Abstract
The remote control includes a central button and side buttons. Touch sensors are associated with each of the buttons, with the central button being associated with a multizone touch pad that is activatable in different manners as a function of the movement of the finger over said pad. A set of pushbutton electromechanical switches is provided, comprising a central switch and one side switch in common for the buttons of each pair of side buttons. Selector means serve, on detecting a state transition of a side switch, to select a control signal as a function of that one of the touch sensors that is activated by contact with one of the side buttons associated with the switch. The movement of the finger over the central button is analyzed in order to distinguish between rectilinear movement and circular movement of the finger, and in order to determine the direction of said movement.
