Researchers have recently invented smart bracelets with wearable sensing technology or wearable sensing technology. Named FingerTrack, this bracelet can continuously track or monitor the whole thing in 3D. The device assumes many positions of the hand and can convert it to 3D. The low-resolution thermal camera in it can capture the subtle movements of the wrist.
The study was published in the journal Proceedings of the ACM on Interactive, Mobile, Wearable, and Ubiquitous Tech.
The device can also be used for sign language translation. In addition to this, the bracelet will help in virtual reality, mobile health, robotic communication with humans, etc.
Cheng Hang, a researcher at Cornell University in the United States, said it was an important invention in recognizing hand movements by looking at wrist structures. This method can be used to accurately detect hand movements in 3D. This allows the position of the whole hand to be captured perfectly.
This method works with absolutely light bracelets so no heavy camera is required. In the case of fingertracks, virtual hands are reconstructed using thermal imaging and machine learning. The four tiny cameras on the bracelet work.
Researchers say that this bracelet will work well for understanding hand gestures. It may be useful in patients with Parkinson’s or Alzheimer’s. References: IANS
