Radar; Hand-gesture recognition; User-defined gestures; Through-materials

Radar signals can penetrate non-conducting materials, such as glass, wood, and plastic, which could enable the recognition of user gestures in environments with poor visibility, occlusion, limited accessibility, and privacy sensitivity. This dataset contains nine gestures from 32 participants recorded with a radar through 3 different materials (wood, glass, and PVC) to explore the feasibility of sensing gestures through materials.
