3D Theremin: A Novel Approach for Convenient “Point and Click”-Interactions in Vehicles

Efficient and intuitive interaction with screens is a topic of ever increasing importance. The same applies for the car domain, where (i) navigation systems use large screens to provide information, (ii) traditional instrument boards are more and more replaced with fully configurable digital screens, and (iii) novel visual information systems such as the head-up display (HUD) find its way into. Capacitive proximity sensing has been identified as promising technique to cope with the lack of support for screen content adaptation by proposing eyes-free, contactless humansystem interaction in a mouse-like manner. While input with a single or dual dimensional capacitive proximity sensing device has been successfully demonstrated, the extension of the same paradigm to support “point & click” operations in 3D is a novelty discussed in this work.
