Outlines the work of the Interactive Image Based Device for EffectiveCommunication project [IBIDEM] in its aim of developing a video phone usefulfor lip-reading by hearing-impaired people, based on a newgeneration of space-variant sensors and using standard telephone lines.The IBIDEM project is constructing a video phone using a camera with aretina-like sensor, a motorized system for moving the viewpoint of thecamera, as well as a display for the transmitted images which will allow highresolution in the area of interest i.e. lips or figures, whilst stillmaintaining a wide field of view. Experiments have been carried out toevaluate the minimum requirements for the video phone in terms of spatial andtemporal resolution and the technical limitations which have to be taken intoaccount in the design of a visual sensor.
