The SkinTrack Technology is a new way to perform touch screen like operation over your own skin. You need to wear the signal giving Ring on the one hand and the wrist band on the other hand. Both components interact with each other and you are able to navigate your smartwatch thru the touch on your skin.
I checked out the homepage and unfortunately the SkinTracker is not available for purchase, yet. It seems to be still a project in development.
Probably they have also have to come up with a more userfriendly signal giving ring than the one that is shown in the video (it looks just like cooper wires)
Very interesting project indeed looking forward to some more updates about it!
Thanks for sharing, good Hunt!
