Abstract: A peripheral device for a computer or the like comprises: a thin flat housing suitable for resting on a work surface and having a generally plane and smooth top surface; a keyboard, and a flat screen disposed in a central zone of the device; and two blank zones situated on either side of said central zone. The dimensions of the housing are chosen so that it constitutes a desk pad that permanently occupies a portion of a work surface. The invention is applicable to improving workstation or computer ergonomics.
