The Perceptual Browser

The Perceptual Browser (PBrowser) is a prototype software demonstrating the introduction of Computer Vision in classical Graphical User Interfaces. Interacting with PBrowser, users control the scrolling in a window with head motion.

As the user tilts the head downwards from a "neutral" position, the content of the window starts to scroll up. As the head is tilted downwards further, the scrolling speed increases. A symmetrical behavior is obtained when moving the head upwards.
