"sEMG 8 channel data using OpenBCI cyton biosensing board and 3D keypoints using LEAP motion controller"

"We present a 3D hand gesture prediction application, leveraging the sEMG signal and the optical hand tracking information. A transformer\u2013encoder classifier (TEC) module is introduced in an IPC-system to predict the 3D-hand gestures using eight monopolar channels from sEMG as input. Using Cyton Biosensing board to acquire biosensing data and 3D key points from LEAP motion IR controller, a 3D hand gesture prediction is implementation in a real time environment.An experimental testbed is setup to acquire, train, and predict the 3D hand gestures within a feasible range of performance. The performance has been evaluated in terms of percentage of correctly classified keypoints (PCK). PCK is measured by first estimating the euclidean distance between the actual and the predicted keypoints. The percentage of keypoints within a threshold distance value are then calculated. Results from the ablation study indicate that the proposed scheme shows a percentage of correctly classified keypoints of up to 72.8%, 92.7%, 97.2%, and 98.6% with a PCK threshold of 5 mm, 10 mm, 20 mm, and 30 mm, respectively."
