François Bérard

Welcome ! I am an associate professor (Maître de Conférence) at Ensimag, Grenoble INP, Grenoble, France.

I am a member of the Computer-Human Interaction group at the LIG laboratory. My research interests are in real-time Computer Vision for Human-Computer Interaction, large interactive surfaces, 3D interaction, Human motor control limits.

On the Web


A library of service for the development of innovative interactive systems. At the moment, only the GMLcanvas is available for download.


Also known as "FingerPaint, one step beyond !" Images and movies available.

Perceptual Window

Also known as "The Perceptual Browser, the Revenge". Screenshots and movies available.

Perceptual Browser

Scroll your windows using head motion. Screenshots, movies and dowloadable demoes are available.


I contributed to the MediaLab's SmartSpaces demo (local mirror) at SIGGRAPH'96.


This system was the demonstration program I developped for the DEA (master), the web page is rich in pictures and movies, avoid it if you have a slow link.
