ForceField: Visualizing Intermaterial Interaction through Floor and Depth Sensing

ForceField realizes the measurement of intermaterial contact forces across any surface within a room-scale environment without the need for additional device attachments to bodies or objects. It achieves this by acquiring a 3D model through a depth sensor and capturing ground pressure through a floor sensor, and then reconstructing contact forces between surfaces where no sensors are attached, such as when a hand pushes a desk, or people push against each other, from information on force and geometry. Through this unobtrusive environmental measurement approach, ForceField opens up the possibility of highly physical spatial interactions in domains such as healthcare, sports, and entertainment.
