Embodiments are disclosed that relate to hover detection in interactive display devices. One embodiment provides an interactive display device comprising a display panel configured to display an image on an interactive surface, an imaging optical wedge disposed adjacent to the display panel, an image sensor configured to capture an image of an object located in front of the interactive surface and spaced from the interactive surface by capturing the image through the imaging optical wedge, a logic subsystem, and a data-holding subsystem comprising instructions executable by the logic subsystem to operate the display panel and the image sensor, and to detect a hover input based upon one or more images received from the image sensor. |
