Abstract
Heads-up display systems for vehicles which generate a virtual display in a field of view of an occupant of the vehicle when facing outward of the vehicle. A control system is coupled to the heads-up display system and detects an action by the occupant, e.g., touching of a touch pad, and controls the content of the virtual display being generated by the heads-up display system based on the detected action. The touch pad may include a surface acoustical wave (SAW) device whereby touching causes a particular returned signal from the SAW substrate, with this particular returned signal being processable into an activation of the manner in which the touch pad was touched.
