The dataset was collected from five healthy right-handed subjects (3 male, 2 female), 23–30 years old, with BMI ≈ 21. An FMG armband with 24 tactile sensors (two sensing pads, 12 sensors each, positioned on the ventral and dorsal sides of the upper right forearm) recorded signals while subjects mimicked a GUI-controlled virtual hand used as gesture ground truth.

The protocol included 11 hand/wrist gestures. Each gesture was held for 5 s and then returned to a rest (RT) position. Signals were sampled at 900 Hz, producing 4500 samples per channel per gesture (5 s × 900 samples/s), and were time-stamped and saved together with real-time hand position via a C# software suite. The full stimulus sequence was repeated 10 times, yielding 10 trials per gesture per subject, i.e., 110 gesture instances per subject (11 gestures × 10 trials), with each instance represented as a 4500 × 24 signal matrix.
