Finger tracking

Traditional VR controllers like the Oculus Touch or the VIVE controllers allow the user to interact with virtual content by pressing buttons and pulling triggers.

Although this concept is very similar to the legacy console controllers, it is counter-intuitive for users to handle different buttons, especially since in VR one cannot see the real controller.

Furthermore, holding a device like this in your hand significantly dampens your immersion and lowers your VR experience quality.

A more natural and intuitive way to interact with virtual and augmented reality would be to directly use your hands and fingers as the input device - like in the real world.

However, purely optical hand- and finger-tracking systems like Leap Motion have a hard time to track fingers due to occlusions caused by the user's own hands, and thus, more advanced technologies are required.

One possibility to track finger gestures is to attach flex sensors over the joints of the finger segments, measuring the degree of bending of the finger.

While this approach is quite robust, it only measures two degrees of freedom for each finger and thus, the spreading of the fingers cannot be be tracked.

The VRfree glove system in contrast deploys multiple inertial measurement units (IMU) on finger segments, capable to measure their full 3D orientation.

Using in-house developed, hardware accelerated sensor fusion algorithms, the VRfree glove is capable of precisely tracking full hand gestures at high frame rates and low latency.

As a results you can use your finger tips to naturally interact with any virtual object in the same way as you do in the real world, making your journey through virtual reality a fully immersive experience!
