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.
