2 Overall objectives

Interactive devices are everywhere: we wear them on our wrists and belts; we consult them from purses and pockets; we read them on the sofa and on the metro; we rely on them to control cars and appliances; and soon we will interact with them on living room walls and billboards in the city. Over the past 30 years, we have witnessed tremendous advances in both hardware and networking technology, which have revolutionized all aspects of our lives, not only business and industry, but also health, education and entertainment. Yet the ways in which we interact with these technologies remains mired in the 1980s. The graphical user interface (GUI), revolutionary at the time, has been pushed far past its limits. Originally designed to help secretaries perform administrative tasks in a work setting, the GUI is now applied to every kind of device, for every kind of setting. While this may make sense for novice users, it forces expert users to use frustratingly inefficient and idiosyncratic tools that are neither powerful nor incrementally learnable.

ExSitu explores the limits of interaction — how extreme users interact with technology in extreme situations. Rather than beginning with novice users and adding complexity, we begin with expert users who already face extreme interaction requirements. We are particularly interested in creative professionals, artists and designers who rewrite the rules as they create new works, and scientists who seek to understand complex phenomena through creative exploration of large quantities of data. Studying these advanced users today will not only help us to anticipate the routine tasks of tomorrow, but to advance our understanding of interaction itself. We seek to create effective human-computer partnerships, in which expert users control their interaction with technology. Our goal is to advance our understanding of interaction as a phenomenon, with a corresponding paradigm shift in how we design, implement and use interactive systems. We have already made significant progress through our work on instrumental interaction and co-adaptive systems, and we hope to extend these into a foundation for the design of all interactive technology.

3 Research program

We characterize Extreme Situated Interaction as follows:

Extreme users. We study extreme users who make extreme demands on current technology. We know that human beings take advantage of the laws of physics to find creative new uses for physical objects. However, this level of adaptability is severely limited when manipulating digital objects. Even so, we find that creative professionals––artists, designers and scientists––often adapt interactive technology in novel and unexpected ways and find creative solutions. By studying these users, we hope to not only address the specific problems they face, but also to identify the underlying principles that will help us to reinvent virtual tools. We seek to shift the paradigm of interactive software, to establish the laws of interaction that significantly empower users and allow them to control their digital environment.

Extreme situations. We develop extreme environments that push the limits of today's technology. We take as given that future developments will solve “practical" problems such as cost, reliability and performance and concentrate our efforts on interaction in and with such environments. This has been a successful strategy in the past: Personal computers only became prevalent after the invention of the desktop graphical user interface. Smartphones and tablets only became commercially successful after Apple cracked the problem of a usable touch-based interface for the iPhone and the iPad. Although wearable technologies, such as watches and glasses, are finally beginning to take off, we do not believe that they will create the major disruptions already caused by personal computers, smartphones and tablets. Instead, we believe that future disruptive technologies will include fully interactive paper and large interactive displays.

Our extensive experience with the Digiscope WILD and WILDER platforms places us in a unique position to understand the principles of distributed interaction that extreme environments call for. We expect to integrate, at a fundamental level, the collaborative capabilities that such environments afford. Indeed almost all of our activities in both the digital and the physical world take place within a complex web of human relationships. Current systems only support, at best, passive sharing of information, e.g., through the distribution of independent copies. Our goal is to support active collaboration, in which multiple users are actively engaged in the lifecycle of digital artifacts.

Extreme design. We explore novel approaches to the design of interactive systems, with particular emphasis on extreme users in extreme environments. Our goal is to empower creative professionals, allowing them to act as both designers and developers throughout the design process. Extreme design affects every stage, from requirements definition, to early prototyping and design exploration, to implementation, to adaptation and appropriation by end users. We hope to push the limits of participatory design to actively support creativity at all stages of the design lifecycle. Extreme design does not stop with purely digital artifacts. The advent of digital fabrication tools and FabLabs has significantly lowered the cost of making physical objects interactive. Creative professionals now create hybrid interactive objects that can be tuned to the user's needs. Integrating the design of physical objects into the software design process raises new challenges, with new methods and skills to support this form of extreme prototyping.

Our overall approach is to identify a small number of specific projects, organized around four themes: Creativity, Augmentation, Collaboration and Infrastructure. Specific projects may address multiple themes, and different members of the group work together to advance these different topics.

6 New software and platforms

6.1 New software

6.1.1 Digiscape

  • Name: Digiscape
  • Keywords: 2D, 3D, Node.js, Unity 3D, Video stream
  • Functional Description: Through the Digiscape application, the users can connect to a remote workspace and share files, video and audio streams with other users. Application running on complex visualization platforms can be easily launched and synchronized.

6.1.2 Touchstone2

  • Keyword: Experimental design
  • Functional Description:

    Touchstone2 is a graphical user interface to create and compare experimental designs. It is based on a visual language: Each experiment consists of nested bricks that represent the overall design, blocking levels, independent variables, and their levels. Parameters such as variable names, counterbalancing strategy and trial duration are specified in the bricks and used to compute the minimum number of participants for a balanced design, account for learning effects, and estimate session length. An experiment summary appears below each brick assembly, documenting the design. Manipulating bricks immediately generates a corresponding trial table that shows the distribution of experiment conditions across participants. Trial tables are faceted by participant. Using brushing and fish-eye views, users can easily compare among participants and among designs on one screen, and examine their trade-offs.

    Touchstone2 plots a power chart for each experiment in the workspace. Each power curve is a function of the number of participants, and thus increases monotonically. Dots on the curves denote numbers of participants for a balanced design. The pink area corresponds to a power less than the 0.8 criterion: the first dot above it indicates the minimum number of participants. To refine this estimate, users can choose among Cohen’s three conventional effect sizes, directly enter a numerical effect size, or use a calculator to enter mean values for each treatment of the dependent variable (often from a pilot study).

    Touchstone2 can export a design in a variety of formats, including JSON and XML for the trial table, and TSL, a language we have created to describe experimental designs. A command-line tool is provided to generate a trial table from a TSL description.

    Touchstone2 runs in any modern Web browser and is also available as a standalone tool. It is used at ExSitu for the design of our experiments, and by other Universities and research centers worldwide. It is available under an Open Source licence at https://touchstone2.org.

6.1.3 UnityCluster

  • Keywords: 3D, Virtual reality, 3D interaction
  • Functional Description:

    UnityCluster is middleware to distribute any Unity 3D (https://unity3d.com/) application on a cluster of computers that run in interactive rooms, such as our WILD and WILDER rooms, or immersive CAVES (Computer-Augmented Virtual Environments). Users can interact the the application with various interaction resources.

    UnityCluster provides an easy solution for running existing Unity 3D applications on any display that requires a rendering cluster with several computers. UnityCluster is based on a master-slave architecture: The master computer runs the main application and the physical simulation as well as manages the input, the slave computers receive updates from the master and render small parts of the 3D scene. UnityCluster manages data distribution and synchronization among the computers to obtain a consistent image on the entire wall-sized display surface.

    UnityCluster can also deform the displayed images according to the user's position in order to match the viewing frustum defined by the user's head and the four corners of the screens. This respects the motion parallax of the 3D scene, giving users a better sense of depth.

    UnityCluster is composed of a set of C Sharp scripts that manage the network connection, data distribution, and the deformation of the viewing frustum. In order to distribute an existing application on the rendering cluster, all scripts must be embedded into a Unity package that is included in an existing Unity project.

6.1.4 VideoClipper

  • Keyword: Video recording
  • Functional Description:

    VideoClipper is an IOS app for Apple Ipad, designed to guide the capture of video during a variety of prototyping activities, including video brainstorming, interviews, video prototyping and participatory design workshops. It relies heavily on Apple’s AVFoundation, a framework that provides essential services for working with time-based audiovisual media on iOS (https://developer.apple.com/av-foundation/). Key uses include: transforming still images (title cards) into video tracks, composing video and audio tracks in memory to create a preview of the resulting video project and saving video files into the default Photo Album outside the application.

    VideoClipper consists of four main screens: project list, project, capture and import. The project list screen shows a list with the most recent projects at the top and allows the user to quickly add, remove or clone (copy and paste) projects. The project screen includes a storyboard composed of storylines that can be added, cloned or deleted. Each storyline is composed of a single title card, followed by one or more video clips. Users can reorder storylines within the storyboard, and the elements within each storyline through direct manipulation. Users can preview the complete storyboard, including all titlecards and videos, by pressing the play button, or export it to the Ipad’s Photo Album by pressing the action button.

    VideoClipper offers multiple tools for editing titlecards and storylines. Tapping on the title card lets the user edit the foreground text, including font, size and color, change background color, add or edit text labels, including size, position, color, and add or edit images, both new pictures and existing ones. Users can also delete text labels and images with the trash button. Video clips are presented via a standard video player, with standard interaction. Users can tap on any clip in a storyline to: trim the clip with a non-destructive trimming tool, delete it with a trash button, open a capture screen by clicking on the camera icon, label the clip by clicking a colored label button, and display or hide the selected clip by toggling the eye icon.

    VideoClipper is currently in beta test, and is used by students in two HCI classes at the Université Paris-Saclay, researchers in ExSitu as well as external researchers who use it for both teaching and research work. A beta test version is available on demand under the Apple testflight online service.

6.1.5 WildOS

  • Keywords: Human Computer Interaction, Wall displays
  • Functional Description:

    WildOS is middleware to support applications running in an interactive room featuring various interaction resources, such as our WILD and WILDER rooms: a tiled wall display, a motion tracking system, tablets and smartphones, etc. The conceptual model of WildOS is a platform, such as the WILD or WILDER room, described as a set of devices and on which one or more applications can be run.

    WildOS consists of a server running on a machine that has network access to all the machines involved in the platform, and a set of clients running on the various interaction resources, such as a display cluster or a tablet. Once WildOS is running, applications can be started and stopped and devices can be added to or removed from the platform.

    WildOS relies on Web technologies, most notably Javascript and node.js, as well as node-webkit and HTML5. This makes it inherently portable (it is currently tested on Mac OS X and Linux). While applications can be developed only with these Web technologies, it is also possible to bridge to existing applications developed in other environments if they provide sufficient access for remote control. Sample applications include a web browser, an image viewer, a window manager, and the BrainTwister application developed in collaboration with neuroanatomists at NeuroSpin.

    WildOS is used for several research projects at ExSitu and by other partners of the Digiscope project. It was also deployed on several of Google's interactive rooms in Mountain View, Dublin and Paris. It is available under an Open Source licence at https://bitbucket.org/mblinsitu/wildos.

6.1.6 StructGraphics

  • Keywords: Data visualization, Human Computer Interaction
  • Functional Description: StructGraphics is a user interface for creating data-agnostic and fully reusable designs of data visualizations. It enables visualization designers to construct visualization designs by drawing graphics on a canvas and then structuring their visual properties without relying on a concrete dataset or data schema. Overall, StructGraphics follows the inverse workflow than traditional visualization-design systems. Rather than transforming data dependencies into visualization constraints, it allows users to interactively define the property and layout constraints of their visualization designs and then translate these graphical constraints into alternative data structures. Since visualization designs are data-agnostic, they can be easily reused and combined with different datasets.

6.2 New platforms

6.2.1 WILD

Participants: Michel Beaudouin-Lafon, Cédric Fleury, Olivier Gladin.

WILD is our first experimental ultra-high-resolution interactive environment, created in 2009. In 2019-2020 it received a major upgrade: the 16-computer cluster was replaced by new machines with top-of-the-line graphics cards, and the 32-screen display was replaced by 32 32" 8K displays resulting in a resolution of 1 giga-pixels (61 440 x 17 280) for an overall size of 5m80 x 1m70 (280ppi). An infrared frame adds multitouch capability to the entire display area. The platform also features a camera-based motion tracking system that lets users interact with the wall, as well as the surrounding space, with various mobile devices.

6.2.2 WILDER

Participants: Michel Beaudouin-Lafon, Cédric Fleury, Olivier Gladin.

WILDER (Figure 1) is our second experimental ultra-high-resolution interactive environment, which follows the WILD platform developed in 2009. It features a wall-sized display with seventy-five 20" LCD screens, i.e. a 5m50 x 1m80 (18' x 6') wall displaying 14 400 x 4 800 = 69 million pixels, powered by a 10-computer cluster and two front-end computers. The platform also features a camera-based motion tracking system that lets users interact with the wall, as well as the surrounding space, with various mobile devices. The display uses a multitouch frame (one of the largest of its kind in the world) to make the entire wall touch sensitive.

WILDER was inaugurated in June, 2015. It is one of the ten platforms of the Digiscope Equipment of Excellence and, in combination with WILD and the other Digiscope rooms, provides a unique experimental environment for collaborative interaction.

In addition to using WILD and WILDER for our research, we have also developed software architectures and toolkits, such as WildOS and Unity Cluster, that enable developers to run applications on these multi-device, cluster-based systems.

7 New results

7.1 Fundamentals of Interaction

Participants: Michel Beaudouin-Lafon, Wendy Mackay, Cédric Fleury, Theophanis Tsandilas, Benjamin Bressolette, Alexandre Eiselmeyer, Camille Gobert, Julien Gori, Han Han, Miguel Renom, Martin Tricaud, Yiran Zhang.

In order to better understand fundamental aspects of interaction, ExSitu conducts in-depth observational studies and controlled experiments which contribute to theories and frameworks that unify our findings and help us generate new, advanced interaction techniques. Our theoretical work also leads us to deepen or re-analyze existing theories and methodologies in order to gain new insights.

Following up on our work on fundamental laws of Human-Computer Interaction (HCI), such as Fitts' Law, we revisited the validity of Hick's Law 24. Hick's law is a key quantitative law in Psychology that relates reaction time to the logarithm of the number of stimulus-response alternatives in a task. The law, however, is often misunderstood in HCI. We conducted an in-depth review of the literature on choice-reaction time and concluded that: (1) Hick's law contradicts the popular principle that 'less is better'; (2) logarithmic growth of observed temporal data is not necessarily interpretable in terms of Hick's law; (3) the stimulus-response paradigm is rarely relevant to HCI tasks, where choice-reaction time can often be assumed to be constant; and (4) for user interface design, a detailed examination of the effects of psychological processes such as visual search and decision making on choice-reaction time is more fruitful than a mere reference to Hick's law.

In collaboration with researchers at the University of Zurich, we also contributed to research methodology. Argus 16 addresses a key challenge that HCI researchers face when designing a controlled experiment i.e. choosing the appropriate number of participants, or sample size. A priori power analysis examines the relationships among multiple parameters, including the complexity associated with human participants, e.g., order and fatigue effects, to calculate the statistical power of a given experiment design. We created Argus, a tool that supports interactive exploration of statistical power: Researchers specify experiment design scenarios with varying confounds and effect sizes. Argus then simulates data and visualizes statistical power across these scenarios, which lets researchers interactively weigh various trade-offs and make informed decisions about sample size. We describe the design and implementation of Argus, and the results of a study where researchers used Argus to choose the sample size for a Fitts’s law experiment.

In the context of identifying and applying unifying principles of interaction, we conducted several studies and created prototypes that illustrate the power of this theoretical and methodological approach.

The first study focused on document editing: Writing technical documents frequently requires following constraints and consistently using domain-specific terms. We interviewed 12 legal professionals and found that they must rely on their memory to manage dependencies and maintain consistent vocabulary within their documents. We created Textlets 20, interactive objects that reify text selections into persistent items. Textlets help manage consistency and constraints within the document, including selective search and replace, word count, and alternative wording. A preliminary evaluation showed that users were able to use Textlets to perform advanced tasks. They also spontaneously generated new strategies for search-and-replace and for identifying unwanted words in a document. Textlets is a powerful new technique for text editing, an area that has long since been considered as "solved" by commercial word processors.

The second study addressed the management of consistency across documents by knowledge workers. We interviewed 23 scientists and found that they all had difficulties using the file system to keep track of, re-find and maintain consistency among related but distributed information. We created FileWeaver 18, a system that automatically detects dependencies among files without explicit user action, tracks their history, and lets users interact directly with the graphs representing these dependencies and version history. Changes to a file can trigger recipes, either automatically or under user control, to keep the file consistent with its dependants. Users can merge variants of a file, e.g. different output formats, into a polymorphic file, or morph, and automate the management of these variants. By making dependencies among files explicit and visible, FileWeaver facilitates the automation of workflows by scientists and other users who rely on the file system to manage their data.

The third study targeted users who create visualizations. We studied how to enable users to create custom visualizations without programming. Despite their expressive power, previous visualization authoring systems often assume that users want to generate visual representations that they already have in mind rather than explore designs. They also impose a data-to-graphics workflow, where binding data dimensions to graphical properties is a necessary step for generating visualization layouts. Targeting visualization-design tasks, we introduced StructGraphics 15, an approach for creating data-agnostic and fully reusable visualization designs. StructGraphics enables designers to construct visualization designs by drawing graphics on a canvas and then structuring their visual properties without relying on a concrete dataset or data schema. In StructGraphics, tabular data structures are derived directly from the structure of the graphics (Figure 2). Later, designers can link these structures with real datasets through a spreadsheet user interface. StructGraphics supports the design and reuse of complex data visualizations by combining graphical property sharing, by-example design specification, and persistent layout constraints. We demonstrated the power of the approach through a gallery of visualization examples and reflected on its strengths and limitations in interaction with graphic designers and data visualization experts.

The StructGrapher’s user interface consists of: (a) a library of reusable visualization structures, (b) a visualization sketcher for drawing basic shapes and grouping them into collections, (c) a property inspector for exposing and structuring graphical properties, and (d) a spreadsheet for creating mappings between properties and data. The approach enables designers to construct data-agnostic visualizations and create flexible bindings with data.

The approach enables designers to construct data-agnostic visualizations and create flexible bindings with data.

We also investigated navigation in virtual reality, and more specifically, teleportation with head-mounted displays. Basic teleportation usually moves a user's viewpoint to a new destination of the virtual environment without taking into account the physical space surrounding them. However, considering the user's real workspace is crucial for preventing them from reaching its limits and thus managing direct access to multiple virtual objects. We proposed to display a virtual representation of the user's real workspace before the teleportation, and compare manual and automatic techniques for positioning such a virtual workspace 28. Controlled experiments show that both manual and automatic techniques are more efficient than the basic teleportation for reaching many objects of the virtual environment. In addition, manual techniques seems more suitable for crowded scenes than automatic techniques.

7.2 Human-Computer Partnerships

Participants: Wendy Mackay, Baptiste Caramiaux, Wanyu Liu, Janin Koch, Téo Sanchez, Nicolas Taffin, Theophanis Tsandilas.

ExSitu is interested in designing effective human-computer partnerships, in which expert users control their interaction with technology. Rather than treating the human users as the 'input' to a computer algorithm, we explore human-centered machine learning, where the goal is to use machine learning and other techniques to increase human capabilities. Much of human-computer interaction research focuses on measuring and improving productivity: our specific goal is to create what we call 'co-adaptive systems' that are discoverable, appropriable and expressive for the user.

We continued our collaboration with the University of Paris Descartes and the ILDA Inria team to help data analysts query massive data series collections within interaction times. Even though the data management community has developed sophisticated techniques for answering similarity queries quickly, the state-of-the-art indexes are still far from achieving interactive response times — depending on the dataset size and the machine, a single query can take from a few seconds to dozens of minutes. We presented and experimentally evaluated a new probabilistic learning-based method 17 that provides quality guarantees for progressive Nearest-Neighbor query answering. We provided both initial and progressive estimates of the final answer that are getting better during the similarity search, as well suitable stopping criteria for the progressive queries. Experiments with synthetic and diverse real datasets demonstrated that our prediction methods constitute the first practical solution to the problem, significantly outperforming competing approaches.

We collaborated with researchers at Aalto University to create an intelligent tool that helps designers create inspirational mood boards to express their design ideas visually, through collages of images and text. They find appropriate images and reflect on them as they explore emergent design concepts. We designed and developed Semantic Collage23, a digital mood board tool creation tool that attaches semantic labels to images by applying a state- of-the-art semantic labeling algorithm. SemanticCollage helps designers to 1) translate vague, visual ideas into search terms; 2) make better sense of and communicate their designs; while 3) not disrupting their creative flow. Empirical work included and initial participatory design workshop, a survey of professional designers,and a structured observation with 12 professional designers that demonstrated how semantic labels help designers successfully guide image search and find relevant words that articulate their abstract, visual ideas.

SemanticCollage is a semantically enriched digital mood board tool for image collection and interpretation. Blue tools support image and text manipulation; Red tools provide semantic labels.

7.3 Creativity

Participants: Sarah Fdili Alaoui, Baptiste Caramiaux, Wendy Mackay, Viktor Gustafsson, Shu Yuan Hsueh, Janin Koch, Jean-Philippe Rivière, Nicolas Taffin, Theophanis Tsandilas.

ExSitu is interested in understanding the work practices of creative professionals, particularly artists, designers, and scientists, who push the limits of interactive technology. We follow a multi-disciplinary participatory design approach, working with both expert and non-expert users in diverse creative contexts.

Firstly, Exsitu explores methodological considerations. For example, Sarah Fdili Alaoui collaborated with the researchers in Simon Fraser University to study how micro-phenomenology has been used in HCI/Design research since 2001 to articulate user’s experience in third wave HCI and creative contexts  26. The paper illustrates how this method has been applied by the selected experts through developing a practice, and present conditions under which the descriptions of the experience unfold, and the values that this method can provide to HCI/Design field. The paper has earned a best paper award.

Members of Exsitu organised a workshop during CHI 2020 called Where Art Meets Technology: Integrating Tangible and Intelligent Tools in Creative Processes  22. The focus of this workshop is to bring together researchers and practitioners to explore what the future of digital art and design will hold. The exploration will centre around synthesizing key challenges and questions, along with ideas for future interaction technologies that consider mobile and tangible aspects of digital art.

ExSitu has explored diverse creative contexts, including video games, music, and dance. Our work with video games show that players in modern Massively Multiplayer Online Role-Playing Games progress through ambitiously designed narratives, but have no real influence on the game, since only their characters' data, not the game environment, persists  19. Gustafsson et al. introduce Narrative Substrates, a theoretical framework for designing game architectures that represent, manage, and persist traces of player activity as unique, interactive content. They identify key benefits and challenges of their approach and argue that reification of emergent narratives offers new design opportunities for creating truly interactive games.

The second creative context is music and sound design. Baptiste Caramiaux collaborated in the study of timbre, an auditory attribute that conveys crucial information about the identity of a sound source, especially for music  14. The authors use a data-driven computational account to reveal the acoustic correlates of timbre. Human dissimilarity ratings are simulated with metrics learned on acoustic spectrotemporal modulation models inspired by cortical processing. The authors observe that timbre has both generic and experiment-specific acoustic correlates. These findings provide a broad overview of former studies on musical timbre and identify its relevant acoustic substrates according to biologically inspired models. Additionally, Baptiste Caramiaux collaborated in a study which examines mapping design  27. Twelve skilled NIME users designed a mapping from a T-Stick to a subtractive synthesizer and were interviewed about their approach to mapping design. The authors present a thematic analysis of the interviews and suggest that the mapping design process is an iterative process that alternates between two working modes: diffuse exploration and directed experimentation.

The third creative context is dance. Jean-Philippe Rivière defended his thesis  33 on “Capturing traces of the dance learning process”, which encompasses both focused and long-term empirical studies with dancers and choreographers, as well as a novel technology, MoveOn, which supports dance learning as well as provides a in-context tool for capturing and analysing learning and choreographic creative practice.

In Digital art, and in intersection with the use of artificial intelligence, Baptiste Caramiaux provided a five-year art and science collaboration that proposes a methodology combining computational learning technology -Machine Learning (ML) and Artificial Intelligence (AI)- with interactive music performance and choreography  29. The article described two collaborative artistic works Corpus Nil and Humane Methods, with the artistic motivations and reflections on the methodology developed during the collaboration as well as the conceptual shift of computational learning technologies, from ML to AI, and its impact on Music performance. Baptiste Caramiaux also proposes a report with an overview on the Use of Artificial Intelligence in the Cultural and Creative Sectors  31.

Finally, Theophanis Tsandilas successfully defended his Habilitation 30, reviewing the results of more than 10 years of research at Inria on interactive tools and techniques for creative activities.

7.4 Collaboration

Participants: Cédric Fleury, Michel Beaudouin-Lafon, Wendy Mackay, Joanna McGrenere, Arthur Fages, Janin Koch, Yi Zhang.

ExSitu explores new ways of supporting collaborative interaction and remote communication. In particular, we studied co-located and remote collaboration on large wall-sized displays, video-conferencing systems, and computer tools to support collaborative activities for design and creativity.

In an industrial context, design review is an iterative process which mainly relies on two steps involving many stakeholders: design discussion and CAD data adjustment. We investigated how a wall-sized display could be used to merge these two steps by allowing multidisciplinary collaborators to simultaneously generate and explore design alternatives. We designed ShapeCompare 25 based on the feedback from a usability study. It enables multiple users to compute and distribute CAD data with touch interaction (Figure 4). To assess the benefit of the wall-sized display in such context, we ran a controlled experiment which aims to compare ShapeCompare with a visualization technique suitable for standard screens. The results show that pairs of participants performed a constraint solving task faster and used more deictic instructions with ShapeCompare. From these findings, we draw generic recommendations for collaborative exploration of design alternatives.

In collaboration with researchers at the University of Aalto, we worked with professional designers to create a collaborative tool to support mood board design. Professional designers create mood boards to explore, visualize, and communicate hard-to-express ideas. We developed ImageSense12, an intelligent, collaborative ideation tool that combines individual and shared work spaces, as well as collaboration with multiple forms of intelligent agents. In the collection phase, ImageSense offers fluid transitions between serendipitous discovery of curated images via ImageCascade, combined text- and image-based Semantic search, and intelligent AI suggestions for finding new images. For later composition and reflection, ImageSense provides semantic labels, generated color palettes, and multiple tag clouds to help communicate the intent of the mood board. A study of nine professional designers revealed nuances in designers’ preferences for designer-led, system-led, and mixed-initiative approaches that evolve throughout the design process. We discuss the challenges in creating effective human-computer partnerships for creative activities, and suggest directions for future research.

ShapeCompare  enables non-CAD experts to generate and explore multiple design alternatives on a wall-sized display.

  • Funding: European Research Council (ERC Advanced Grant)
  • Duration: October 2016 - September 2021
  • Coordinator: Michel Beaudouin-Lafon
  • Summary: The goal of ONE is to fundamentally re-think the basic principles and conceptual model of interactive systems to empower users by letting them appropriate their digital environment. The project addresses this challenge through three interleaved strands: empirical studies to better understand interaction in both the physical and digital worlds, theoretical work to create a conceptual model of interaction and interactive systems, and prototype development to test these principles and concepts in the lab and in the field. Drawing inspiration from physics, biology and psychology, the conceptual model combines substrates to manage digital information at various levels of abstraction and representation, instruments to manipulate substrates, and environments to organize substrates and instruments into digital workspaces.

8.2.1 ARCOL

  • Title: Interactive Reinforcement Co-Learning
  • Funding: ANR
  • Type: Young researcher project, Equipment and human resources
  • Duration: 2020-2024
  • Coordinator: Baptiste Caramiaux
  • Partners: ISIR
  • Inria contact: Baptiste Caramiaux
  • Summary: Throughout our lifetime, we are acquiring and improving a wide range of motor skills. In other words, we are able to perform certain movements faster, better and more accurately. The mechanisms at play in motor skill acquisition are complex and not yet fully understood, but there is a consensus that practice is fundamental to skill learning. For instance, a novice musician would spend hours practicing her instrument in order to play music pieces, or to play with other musicians. The same is true for athletes. Practice plays a fundamental role in motor learning and it can, ideally, be designed in order to improve learning performance. However, practice design is challenging as it relies mostly on heuristics (from the learner, a teacher, or a pedagogy), tacit knowledge and varies across learners and along the learning development. Designing good practice sessions is all the more important for beginners who do not have the expertise to select efficient practice routines and to understand what makes a good or a bad practice schedule.
