An unrestrained mouse explores an elevated platform placed above a 75” consumer television. FreemoVR simulates a virtual world consisting of two platforms placed virtually 20cm and 40cm below the physical platform. By tracking the mouse head position, a perspective correct virtual reality can be displayed to the mouse, retaining naturalistic parallax queues and thus the percept of height to the mouse.

The Lab of Andrew Straw studies neural circuits and behavior at the University of Freiburg, Germany. By developing advanced technical systems such as virtual reality arenas, they investigate the mechanistic basis of visual behaviors such as navigation in Drosophila.
