Introduction

ViRoom is a mobile scalable low-cost multi camera setup based on standard consumer hardware. Its applications will be based on detecting and tracking humans in this room, recognizing and storing descriptions of their actions, and selecting the best viewpoint for this actions and generating new view from a virtual camera if necessary. We do not want to restrict the system to one particular room with a specific arrangement. We would like to be able to turn any room into ViRoom just by setting up the cameras.

This project has a strong overlap with STAR project in which we are involved by cooperation with KU Leuven.

Some of the possible applications of of ViRoom are:

• Training videos: An action performed by an instructor can be recorded automatically without human cameramen and editor. Moreover, viewpoints not possible for a real camera can be provided.
• Automated training: After watching a training video the trainee can perform the action in the ViRoom. The system generates a description of the actions, compares them to the descriptions from training video, and notifies the trainee if any differences occur.
• Remote support: An unexperienced person performing some action in a ViRoom can be alerted when his/her actions differ from the predefined pattern. A remote expert can be contacted automatically. This expert will get the best view on the actions in the ViRoom and can provide an advice.
• Telepresence, Augmented reality
