Tactile control interface

A tactile control interface comprising:

• an outer surface;
• means for locating a pressure by a finger of a user on the outer surface;
• wherein the outer surface is implemented by a plate;
• wherein said locating means include:
• at least four force sensors onto which the plate is attached and which are configured to measure a force in a direction substantially normal to a plane of the plate, and
• means for calculating a position of the pressure of the finger on the plate based on measurements supplied by at least three of the force sensors;
• wherein the calculation means is configured to determine the position of the pressure of the finger on the plate through triangulation based on the measurements supplied by said at least three of the force sensors,
• wherein the calculation means is configured to estimate environmental parameters using the measurements supplied by a force sensor that is not used for the triangulation,
• wherein at least one of the force sensors is configured to transmit haptic feedback to the user,
• and
• wherein the calculation means is configured to calculate a plurality of locations through triangulation based on said at least three of the force sensors using, alternately, different combinations of three sensors from among the at least four force sensors;
• and
• a display screen facing the plate, said plate being transparent, wherein said four force sensors are between the plate and the display screen, wherein the display screen is divided into a plurality of parts, wherein each part of the plurality of parts corresponding to a different function,
• wherein the determined the position of the pressure of the finger is in one part of the plurality of parts such that the at least one of the force sensors provides the transmitted haptic feedback in said one part.
