"VR4two" is outdoor virtual reality based on GPS-positioning while being guided by another person.

See VR4two in action in the video above, recorded during the App Olympics event in July 2017

You need a Google Cardboard and a smartphone with a compass and gyroscope to join the game

Check your phone and browser settings and verify that location services are enabled. The positions of players are based on GPS-coordinates.

Finally, make sure your screensaver is turned off.

Find yourself someone to guide you. Put on your VR viewer and start walking towards the virtual ball. The player who reaches the ball first, scores a point.
