Team : i3d
Section: Overall Objectives
The objective of the i3D research team is to contribute to making interaction in virtual worlds as simple and intuitive as in the real world.
To this end, three research axes are privileged:
Interaction metaphors and paradigms
Haptic feedbacks (force or tactile feedback)
Human factors study
The objective of the i3D research team is to contribute to making interaction in virtual worlds as simple and intuitive as in the real world. We focus on:
Spatial approaches: spatial input and output.
Immersive environments: immersion of the user into the virtual world or immersion of the application into the user's real world.
Better exploitation of the user's various sensory channels such as visual and haptic.
The research activities are based on the "Workbench", a system that was chosen for its potentialities in terms of interaction and its adequation to the main approaches mentionned above (see 3.3).
Research of the i3d group is organized around three themes:
The study of interaction metaphors and paradigms. Tasks apparently as simple as displacement inside a virtual scene or catching and repositioning an object are still difficult to realize in a virtual world today. The objective of this theme is to study new paradigms and metaphors of interaction using the approaches quoted above.
The study of haptic feedbacks. There are several ways to return a haptic feedback: active haptic feedback (requiring the use of a haptic feedback device), pseudo-haptic feedback, passive haptic feedback (makes use of a prop), and sensory substitution. The objective of this theme is to study these different approaches in order to have a better characterization of haptic feedback according to the completed task.
Human factors study. In addition to the two previous themes, the research group aims at carrying out experiments whenever possible. These experiments are either carried out to provide a basis for the research, such as psychophysic experiments on human perception or evaluation of existing techniques and peripherals, or evaluation of approaches developed in the group.
The i3D group wishes to emphasize the genericity of the proposed solutions. The results are developed with the objective to be integrated into various applications within different application fields. However, concerning applications, the group currently focuses on the most promising applications in term of industrial use for the Workbench:
Interactive exploration of complex data such as data from scientific computation, fractal models or meshes.
Virtual prototyping: assembling/disassembling for industries such as automotive or aeronautic.
