Abstract

This paper reports the result of IBIDEM, a collaborative project supported by the European Union under the Technology Initiative for Elderly and Disabled People-TIDE initiative. The goal of the project has been to build a prototype of a videophone, connected to standard PSTN lines, that can be used by hearing impaired persons in face-to-face communication. The most innovative content of the project has been the design, fabrication and use of a new generation of space-variant visual sensor characterized by a spatial resolution decreasing linearly with distance from the geometric center of the sensor´s chip. This sampling strategy allows, with a limited number of pixels and consequently a high frame rate, transmission of high resolution information for “speech-reading” and a wide field of view for facial expressions and gestures
