Patent ID: 8866753

Claim:
A user interface ( 1 ) comprising a tablet ( 2 ) that can be touched by the user to enter data, one or more buttons ( 4 ) over the tablet ( 2 ) defining fields upon which the user may apply force, marked with symbols, and sensors ( 3 ) which are located beneath the tablet ( 2 ), positioned so as to remain in contact with the tablet ( 2 ), and which all sensors sense any force exerted onto the tablet ( 2 ) and generate signals by sensing the force which are sensed values for each of the sensors; and further comprising a control unit ( 5 ): wherein a template is stored for sorting of the sensors ( 3 ) according to the sensed values in ascending to descending order for each pressed button ( 4 ) and the control unit ( 5 ) compares a momentary sorting of all of the sensors ( 3 ) in ascending to descending order according to the sensed values, without need to proceed to any calculation of the sensed values, by the sensors ( 3 ) when the user applies force over the tablet ( 2 ) to the template sorting particular to each button ( 4 ), and to conclude at the end of this comparison if there is an overlapping pattern between the template sorting and the momentary sorting of the sensors, that the button ( 4 ) corresponding to that specific overlapping pattern has been pressed.
