Abstract
The sensitive display device of the invention comprises a scanned screen in front of which is situated a plate of transparent material; a detector being coupled with the edge of this plate and a specific position on this plate being determined by contact of a diffusing object, such as a finger. The detector picks up a signal which, after processing, enables the position of this point of contact to be determined. The invention may be used, in particular, as an interface between a computer and a user.
