Smatable Vibration Gesture Dataset (4-Channel, 44.1 kHz, Swipe UDLR)

This dataset provides 4-channel table-vibration recordings (44.1 kHz, 16-bit PCM) for swipe-direction gesture recognition (Up/Down/Left/Right). Signals were captured using four synchronized piezoelectric sensors attached under tabletops in two scenarios: (i) DataByPerson (three participants on the same table), and (ii) DataByTable (one participant across three tables). Each target has ten sessions; each session contains 4 classes × 10 trials = 40 samples. The archive includes raw WAV files. See README for protocol and recommended evaluations.
