I thought I should try the Unity modules for a new motion sensing library called BitGym. A Unity/webcam based motion sensing toolkit that works with depth as well as lateral movements.
It, like many Unity3d packages, is just so straight forward to get working. You simply import the package then add a script to an object and there you have it.
An interesting twist though is that you are not locked into the laptop. Unity being able to target different platforms as a runtime (with the right licences) you can build iOS and Android sensing apps.
I have yet to explore how or if this includes skeleton tracking. It was pure Unity3d. The way it should be done 🙂
Determining size and shape and motion on a camera with a single plane it is of course going to be tricky to look at detail of physical form as with the kinect which is really a 3d scanner. However for some sports applications and rep counters it may well be all that is needed. Some further investigation is on the list of things to do.
The toolkit is available to anyone to download and experiment with but that is on a non commercial licence. Obviously full licences need to be bought to do any more with the kit, but it certainly is worth looking at if you are interested in such things.
