Numerous studies are currently focusing on the modelling of humans and their behaviour in 3D environments. The CINEMA project has similar goals but differentiates itself by aiming at enhanced interactions, the creation of mixed reality, and the creation on interactive and reactive acoustical environments. Part of the project consists in gesture recognition of a user, who is given the real-time control of auralization and audio spatialization processes.
The CINEMA project is a collaborative effort between teams at four Belgian universities. The project foresees the development of a real-time system that includes 3D user and environment modelling, extraction of motion parameters, gesture recognition, computation of depth maps, creation of virtual spaces, and auralization and spatialization. The merging of these techniques is expected to produce a tractable 3D model allowing users to interact with a virtual world.

Although much progress has been made in the areas of video and audio processing, there is still a need to find a way of properly combining these elements. The production of a tool for augmented or virtual reality that mixes video and audio could be used for a number of applications: as an educational tool for example, or at cultural places like museums.
This project started on January 2003 and will end in September 2006. It is funded by the Walloon Region, Belgium.The goals of the imaging laboratory of the ULg for the CINEMA project are:
- Extraction of depth maps robust to light changes.
- Extraction of motion parameters.
- Automatic extraction of three-dimensional data about the user.
