Abstract:
A hover touch controller device includes a touch sensor having a touch surface and a proximity sensor. The touch sensor provides two-dimensional position information on when and where a user's finger touches the touch surface. The proximity sensor provides three-dimensional position information on pre-touch events. The pre-touch events corresponding to the user's finger hovering over the touch surface within some maximum depth. The hover touch controller device further includes a processor. The processor determines from the three-dimensional information a hover point projected on the touch surface and determines from the two-dimensional information a touch point on the touch surface. The processor communicates the hover point and the contact point to a display device. This can include correcting for any perceived user interaction issues associated an offset between the hover point and the touch point.
