I need a good solution for basic gesture recognition (touchless), like swipe left, up, down, right, tap.
I've seen http://www.hoverlabs.co/#hover
which looks very cool, but doesn't seem suited for something that could be hidden inside say a panel frame. Can it be enclosed at all? If it is based on capacitance then maybe not.
I've experimented with both PIR sensors and IR emitter/detectors. Both of which work but each have their issues. A pair of PIR or IR sensors can in theory detect swipe direction. But it would be great if their was a nice packaged solution with software for this.
Need something small that can be effectively hidden (maybe some small holes or ir transmissive plastic covering it).
