Currently, hand tracking technology is based on cameras and built-in sensors such as a gyroscope and an accelerometer. While these seem to work well for today's applications, researchers from Cornell University and the University of Wisconsin-Madison have found a potentially better method.
This method of hand tracking, known as FingerTrak, involves the use of heat sensors. These sensors are small and about the size of a pea. These sensors monitor the contours of the wearer's wrist. This has several advantages, one of which is that it can be made smaller than traditional hand tracking wearables, but it can also be used to track more subtle movements.
There are many uses for this technology, e.g. B. the sign language, in which both hand and finger gestures are used. By using heat sensors to record these various movements, computers can interpret and translate sign language. It could possibly also be used for other medical purposes like Parkinson's and Alzheimer's and of course for virtual reality games.
We're not sure when FingerTrak's technology is expected to be commercially available or who will adopt it, but as I said, the potential behind this technology is huge and since VR is still in its infancy, we wouldn't be surprised if this solution could lead to more immersive VR experiences in the future.
