TouchDIVER provides robust 6DoF (6 degrees of freedom) tracking for precise wrist movements in virtual reality, achieved through a combination of optical sensors and inertial measurement units (IMUs). This tracking system guarantees accuracy in various VR applications. In addition to controllers, external tracking systems can be used in VR rooms or structured environments like Location Based Entertainment (LBE). These systems replace headset sensors with arrays of infrared cameras that track reflective markers for precise hand positioning in 3D space. While this approach maintains the headset’s lightweight design, it requires additional equipment.
