TilePoP: Tile-type Pop-up Prop for Virtual Reality
summary
TilePoP builds a floor-mounted pneumatic shape display: a 3x3 array of 27 airbags with stacked cube airbags that inflate into blocky props and can support people by relying on trapped air, measured to support 120 kg. It uses a 22 liter compressor and a 46 liter vacuum tank so cubes fully inflate in about 5 seconds and deflate in 20 seconds. Design details include spiral folding to ensure consistent folding, valve multiplexing for per-tile control, stacking-order rules to prevent topple, and current limits on resolution and stability.
