The invention concerns an interface device for the entry of data into an trument of small volume such as a timepiece and comprises a static touch responsive sensor formed by a plurality of juxtaposed electrodes. An electronic logic circuit on the one hand receives signals emitted by the sensor representing the position of a finger on the sensor and on the other hand provides output clock pulses to a first and a second counter. Switching means in the electronic logic circuit enable the switching of the clock pulses to the first counter if the finger is moved over the sensor at a speed v.sub.1 less than a threshold speed v.sub.2 or to the second counter if the finger is moved over the sensor at a speed v.sub.3 greater than the threshold speed v.sub.2. The invention may be employed in small timepieces for time setting for example.
An interface device for the entry of data into an instrument of small volume such as a timepiece comprising a static touch responsive sensor arranged to be manually actuable with each position of a finger corresponding to at least one symbol which may take the form of a number, letter or special sign, said sensor being formed by the juxtaposition of N electrodes adapted to provide at least N-1 coded information items representative of the position of the finger on the sensor and wherein are provided a sense/speed detecting means, coupled to the sensor for receiving signals therefrom and interpreting the signals to detect the sense and the speed of movement of the finger over the sensor, generating means for generating signals representing data to be selected or modified coupled to a display means for displaying symbols representative of the data on a composite display device comprising at least a first and a second displays, said generating means being coupled to said sense/speed detecting means for receiving signals therefrom for modifying the data controlling symbols appearing on said first display if the finger is moved over said sensor at a speed less than a predetermined speed and on said second display if the finger is moved over said sensor at a speed greater than said predetermined speed.
