After the successful kickstarter campaign they are now working on the product and i am waiting
kickstarter campaign https://www.kickstarter.com/projects/89577853/stem-system-the-best-way-to-interact-with-virtual
latest demonstration https://www.youtube.com/watch?v=C8z-On6FBTM&feature=player_embedded
The stem system uses electromagnetic waves and each controller has 3 coils which gives 6 degrees of freedom. the position updates every 4 milliseconds which is a lot faster than any optical motion tracking system, the kinect 2.0 has en official latency of 60ms and i am very skeptical against kinect 2.0 "a zero button mouse with a lot of latency to it" and it would need a feet controller with buttons(you can train up your ability to control your toes individually) which microsoft doesn't offer yet. The wiimote was nice for shooting games but it is not that well suited for computer gaming and the camera in the controller also has limited viewing angle and of course some latency. The ps4 move controller together with ps4 eye is interesting but than we have the latency for the camera (between 60 and 240hz) plus the latency for the processing, the resolution decreases for higher refresh rates, the problem with the move controller is that it only have 4 buttons, it doesn't offer six axis control(only positional) and it can only be used for the ps4. The ps4 main controller uses a 3-axis gyroscope and 3-axis accelerometer for 6-axis control but then we have no absolute tracking and latency issues.
I have no doubt that electromagnetic motion control is superior all other types of controls, it is the only low latency high fidelity motion control technique, it makes it possible to controls weapons individually(guns, swords, etc) walk using one thumb stick and still be able to access 6 bottoms easily, i am not sure about the the oval buttons with arrows(2/control), alternatively the second thumb stick could be used for something and still at least 4 buttons would be accessible.
It is backwards compartible with razer hydra, supports linux, windows, osx, is fully open source. up to trackers can be used per base and this would be very well suited for VR headsets, the next occulus rift will use a camera and a gyroscope to determine the head position but i hope some VR headset will utilize the stem system since should offers much better performance at low extra cost over just having 2 STEMs. The whole body can still be tracked using inverse kinematics https://www.youtube.com/watch?v=jkOLswJlTBs . It will be launched july this year and the people who backed thecampaign will be the first the recieve their orders.
I didn't back it up during the kickstarter campaign since there where a lot of uncertainties then and i didn't want them to reach the second stretch goal(android/ios support), their current controller is left-right symmetric and is in black/grey instead of white.
