Abstract

A control interface assembly includes a touch sensor panel, a laser assembly, first and second laser detectors, and a controller. The touch sensor panel includes a touch surface extending within a touch plane. The laser assembly emits first and second portions of laser light. At least one of the first and second portions of laser light is directed within a laser plane which is spaced from the touch plane. The first and second laser detectors are positioned to receive the respective first and second portions of laser light. The controller is coupled with each of the touch sensor panel and the first and second laser detectors. The controller is configured to detect engagement of the touch surface by an operator'"'"'s finger and is further configured to detect passage of an operator'"'"'s finger through the laser plane. Vehicles including a control interface assembly are also provided.
