<p>The detection method is characterised by a touch-sensitive control disc (200) associated with a dynamoelectric module detecting said disc rotation, controlling digital data reading and the operation of members and/or devices. Said dynamoelectric module (300), by the fact that its rotor is coupled in rotation with the disc, permanently and simultaneously translates, by loading and modulating of the direct current voltage it generates, the variations in direction and speed of said disc rotation. Said proportional electrical characteristics are converted into digital data so as to control the direction and speed for reading the data stored in a memory observing the fine variations of rotation direction and speed exerted on the control disc. Said disc sensitivity generates, by contact with the user, a signal enabling to control said operation of member(s).</p> |
