Vancouver-based startup BioInteractive Technologies Inc. has developed TENZR: the only accurate, hands-free, camera-free, wrist-worn gesture recognition controller for VR AR. For the last three years the company has focused on developing an easy to use, comfortable, accurate, and reliable gesture recognition wearable that will help replace current mobile VR AR controllers. This innovative product will provide a more immersive experience to users by freeing the hand from holding bulky button-based controllers. TENZR's new design is aimed at developers and early adopters that are interested in building and interfacing with systems that have Bluetooth connectivity. Its new design is comfortable, easy to use, and has a similar form factor to Fitbit Charge.
