With the Gagagu VR-Streamer App in combination with the Gagagu VR-Streamer Server (available on http://www.gagagu.de for free) you are able to transfer the Image output from a game running on your Windows PC (only in windowed mode!) to your iPhone. In combination with some corresponding VR Glasses e.g. Durovis Dive, Google Cardboard, etc. you can simply dive into virtual reality gaming.
At the same time the image stream is transferred to the iPhone you are able to send the sensor data to a corresponding application (e.g OpenTrack; special plugin available on http://www.gagagu.de for free) to realize head tracking. The Software is trimmed to keep the transmission delay as small as possible. In free mode the App will disconnect from Sever after 10 minutes, but it can be restarted. You can unlock the time limitation through in app purchase. Please only unlock the app when everything is working right for you in limited mode!
