    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.

    Abstract: A hover touch controller device includes a touch sensor having a touch surface with a first aspect ratio and a proximity sensor. Information on when and where a user touches the touch surface is detected. Additionally, information on hover-input events is detected. The hover input events correspond to a user's finger hovering over the touch surface within some maximum depth. The hover touch device further includes a controller. The processor communicates three-dimensional spatial information to a Graphical User Interface (GUI). The GUI generates visualizations based on the hover events and the touch events on a display having an interactive surface with a second aspect ratio. The processor further corrects for any issues associated with supporting a variety of GUI designs. This can include correcting for a difference between the first aspect ratio and the second aspect ratio.
