There are plenty of affordable VR headsets available for iOS and Android devices. While they let you watch 3D content and play games, they don’t offer full body tracking. VicoVR aims to change that. It is a smart kit that enables 3D motion sensing and positional tracking for your iOS/Android based VR headset.
The device does not require a battery or PC to work. It can track 19 body joints for up to 2 players. The data is handled wirelessly with low latency. This project is currently getting funded on Indiegogo.
