The device according to the invention comprises a sensor formed by a plurality of capacitive or resistive electrodes. The user searches the symbol to be selected by displacing his finger on the sensor while looking at a control display unit. Any position of the finger on the sensor causes the display of to at least one symbol within an alphanumeric group, these symbols appearing sequentially on the control display. The device does not require any instruction for use nor any indicator marked on the instrument because its working principle is based on permanent visual feedback. The device is compatible with the dimensional requirements of portable instruments of small dimensions, e.g. timepieces.

An interactive device for the input of data into an instrument of small dimensions, comprising: at least one manually actuated sensor having a plurality of N electrodes placed side by side, said N electrodes defining a number greater than N of possible positions of a finger on the sensor; a control display unit for displaying the data to be entered into said instrument to permit inspection of said data; a transcoder coupling said sensor to said control display unit for delivering output signals to said control display unit, each discrete output signal of said transcoder corresponding to one of said possible positions of the finger on said sensor; and electronic means coupled to said control display unit for processing said data; said control display unit being responsive to output signals of said transcoder produced by the movement and position of the finger on said sensor to cause the search and selection, respectively, of one symbol to be entered into said instrument from an alphabet of greater than N symbols.
