Maybe a bit late, since I only just read the last two monthly reports. If you're looking for more "motion controllers" to implement. It may be an idea to consider implementing support for the VR controllers. IE: Vive, Index, Oculus Touch, etc.
While they generally don't have the normal motion sensors, their method of tracking could be translated/converted to match data needed. Also they all come with wrist straps unlike the phones
