Abstract
Device arranged to identify a manual action on a surface performed by a finger (32), comprising a set of sensors (41) each actuable by the finger so as to create a variation of an electrical quantity, these sensors being respectively arranged within a corresponding set of determined zones of the surface. The device further comprises first detection means (42) for detecting, amongst a subset of said sensors (41) which are activated simultaneously, that actuated sensor representing the greatest variation of the electrical quantity.
Claims5
A device for identifying a manual action on a surface performed by a finger, comprising:
- a set of sensors each being actuable by said finger so as to create a variation of an electric quantity, said electrical quantity varying as a function of degree of coverage of the sensor by said finger, these sensors being independent and distinct from each other and respectively arranged within a corresponding set of determined zones of said surface;
- wherein said device further comprises:
- first detection means for detecting, amongst a subset of said sensors which are activated simultaneously, the actuated sensor which has the largest variation of said electrical quantity.
