Abstract: A man-machine interface method comprising generating physical interactions with active zones (10) belonging to an interface object (5), the active zones being associated with predetermined items of information, detecting the active zones where interactions occur by measuring at least one physical magnitude, and associating each detected interaction with the corresponding predetermined item of information. The active zones are defined for a predetermined finite length of time and they are then deactivated at the end of said predetermined length of time, and when interactions with the interface object are detected while the active zones are deactivated, the active zones are automatically redefined as a function of the first detected interactions.

Abstract: Apparatus and methods for locating an impact point on a surface of an object. The object is provided with an acoustic sensor that senses the impact from the acoustic waves that are generated when the object is subjected to the impact. The location of the impact on the surface of the object is determined by a recognition step that includes a comparison of the sensed signal to one or more predetermined signals. Each predetermined signal represents an active zone on the surface of the object. A predetermined signal corresponds to the sensed signal when the impact causing the sensed signal is generated in the active zone represented by the predetermined signal. The impact is associated with the active zone represented by a predetermined signal when the sensed signal and the predetermined signal sufficiently correspond to each other.
