Outlines the work of the Interactive Image Based Device for Effective Communication project [IBIDEM] in its aim of developing a video phone useful for lip‐reading by hearing‐impaired people, based on a new generation of space‐variant sensors and using standard telephone lines. The IBIDEM project is constructing a video phone using a camera with a retina‐like sensor, a motorized system for moving the viewpoint of the camera, as well as a display for the transmitted images which will allow high resolution in the area of interest i.e. lips or figures, whilst still maintaining a wide field of view. Experiments have been carried out to evaluate the minimum requirements for the video phone in terms of spatial and temporal resolution and the technical limitations which have to be taken into account in the design of a visual sensor.
