Project PRIMA has constructed Smart Environments Plateforme, show in figure 5 , in order to test and develop context aware interactive services. The PRIMA Smart Environments Plateforme is equipped with a microphone array, wireless lapel microphones, wide angle surveillance cameras, panoramic cameras, steerable cameras, scanning range sensors and two camera-projector video-interaction devices. The microphone array is used as an acoustic sensor to detect, locate and classify acoustic signals for recognizing human activities. The wide-angle and panoramic cameras provide fields of view that cover the entire room, and allows detection and tracking of individuals. Steerable cameras are used to acquire video of activities from any viewing direction.
Video interaction devices associate a camera with a video projector to provide new modes if man-machine interaction. Such devices may be used for interaction, presentation or capture of information based on natural activity. Examples include selecting menus and buttons with a finger and capturing drawings from paper or a whiteboard. Fixed video interaction devices in the AME have been constructed for a vertical surface (a wall mounted white board) and a horizontal desk-top work-space. Recently a steerable interaction device has been constructed based on a tightly integrated steerable camera-projector pair (SCP). The SCP described below, allows any surface to be used for interaction with information. It also offers a range new sensing techniques, including automatic surveillance of an environment to discover the environment topology, as well as the use of structured light for direct sensing of texture mapped 3D models.
