Abstract
A watch includes a control member which makes it possible to manage one or more electronic functions. The control member includes an optical guide, which extends between a proximal face and a distal face with respect to the middle. A light source is arranged such that it can illuminate the distal face through the optical guide, and an imaging device, including a photodetector, is arranged to capture an image of a portion of the finger of a user of the watch, when they touch the distal face. A processor generates commands based on signals generated by the photodetector, in the way of an optical mouse, for example, to make it possible for the user to browse in a menu displayed on a digital screen.
