A new wrist-mounted device can track the entire human hand in 3D. Designed by researchers at Cornell and the University of Wisconsin, The FingerTrak bracelet can create an abstraction of 20 finger joint positions. Here’s more from Raspberry Pi Pod:
Cheng Zhang, assistant professor of information science and director of Cornell’s new SciFi Lab, where FingerTrak was developed said:
“The most novel technical finding in this work is discovering that the contours of the wrist are enough to accurately predict the entire hand posture,” Zhang said. “This finding allows the reposition of the sensing system to the wrist, which is more practical for usability.”
