Tapping Headset Input

I have heard of some apps implementing "tapping the headset" as a way of adding input interaction. I would very much like to use this as it gets away from the problem of using a keyboard or controller.

Has anyone implemented / heard of this? Is it reliable? Has it been implemented in UE4?

    Replying to my own post;

    I call upon the wisdom of artyom17 to help me figure out if there is a current implementation :)

    Just seems like it's out there but I see little to no info

    Tapping a device is usually achieved by measuring spikes in the raw accelerometer data (fast acceleration in one direction followed by the opposite). When implemented correctly, this input is pretty accurate.

    artyom has been recently upgrading the Oculus bind and is working on getting raw accelerometer data exposed at least in C++. How long until it is available in the vanilla engine is unknown.

    You could in theory use the headset position (derive twice for acceleration) to the same effect, but due to position filtering, the peaks may not be as apparent.
