Figure 1: A modular inflatable actuator as a building block for prototyping room-scale shape-changing interfaces. Each actuator can extend from 15 cm to 150 cm (A-C). By constructing these modular blocks, a designer can easily prototype different room-scale shape-changing interfaces, such as a 5 x 5 array of room-scale shape display that a user can sit down and step on (D-E).
