Watch () including time display means () covered by a crystal (). This watch includes an interface device for controlling a computer cursor. It forms a contactless watch-mouse. For this purpose, a plurality of touch sensitive sensors are arranged so that their sensitive pads () are supported at least partially by the crystal (). The sensitive pads are arranged in particular in the shape of a matrix extending over most of the crystal (). The click function is performed using a push-button () associated with electric contactor or by a pressure sensor or by a touch sensitive sensor provided for this purpose.

Watch including a contactless control device for a computer cursor

The invention concerns a communication device () forming an interface between an electrically coupled reader (), in particular with contact, and at least a radioelectrically coupled contactless device (). The interface () comprises electronic coupling pads (), in particular resistive contact pads, with corresponding coupling elements of the reader (), and transmitting and/or receiving means for electromagnetic waves (), in particular an antenna, designed to enable communication with the contactless electronic device (). The interface () comprises in particular means () for managing data transfer between the contacts () and the antenna () so as to enable communication between the electrically coupled reader (), requiring the insertion of a device with electrically coupled contacts, and the contactless electronic device (). Preferably, the device () is arranged in a portable object capable of being fixed on part of the bearer, in particular a watch.
