ABSTRACT:
The specification and drawings present a new method and apparatus for a touch actuation in an electronic device using a general purpose input board. The input board comprises of a grating of conductors running in one direction (y-lines). Between these conductors there are contacts connected to a grating running in the perpendicular direction a layer below (x-lines). The grating layers are separated by an insulating layer. Various known methods can be used to read the position of, e.g., a conductive actuator touching the input board. The input board can be used as a configurable UI board under a keymat. The input devices on the keymat can be a key, a joystick, a touchpad top membrane, etc. Also, the actuators can be made force-sensitive by detecting a contact surface area. In addition, all components of the general purpose input board can be made of materials substantially transparent to light.
