Claim:
1. 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 and the display panel; a variable diffuser comprising a diffusivity that is controllable between two or more states; a logic subsystem; and a data-holding subsystem comprising instructions executable by the logic subsystem to receive one or more images from the image sensor, detect a hover input based upon the one or more images received from the image sensor, distinguish blur arising due to hover distance from blur arising due to motion by deconvoluting the image using a predetermined diffusivity profile, and display a response to the hover input via the display panel.
