Patent attributes
A multipoint contact detection device includes at least two capacitive or inductive sensitive structures associated with respective primary detection zones of a surface that a person is likely to contact. The sensitive structures are positioned with a separation that is small enough between them to define at least one intermediate detection zone that the person is likely to contact while exerting a capacitive or inductive disturbance on the adjacent sensitive structures. The device also includes a processing circuit configured to detect, for each sensitive structure, a disturbance induced by the person coming into proximity or into contact and locating the region or regions of the surface with which the person comes into contact relative to the primary detection zones and the one or more intermediate detection zones.
