Figure 2: Acoustic Virtual Reality System
The research team of Dr. Akihiro Funamizu, Prof. Bernd Kuhn, and Prof. Kenji Doya from OIST built a virtual reality system in which a mouse can be made to believe it was walking around freely, but in reality, it was fixed under a microscope. In this system, twelve speakers are placed around the mouse. The speakers generate sound based on the movement of the mouse running on the spherical treadmill (left). When the mouse reaches the virtual sound source it will get a droplet of sugar water as a reward.
