Large-scale shape-changing interfaces have great potential, but creating such systems requires substantial time, cost, space, and efforts, which hinders the research community to explore interactions beyond the scale of human hands. We introduce modular inflatable actuators as building blocks for prototyping room-scale shape-changing interfaces. Each actuator can change its height from 15cm to 150cm, actuated and controlled by air pressure. Each unit is low-cost (8 USD), lightweight (10 kg), compact (15 cm), and robust, making it well-suited for prototyping room-scale shape transformations. Moreover, our modular and reconfigurable design allows researchers and designers to quickly construct different geometries and to explore various applications. This paper contributes to the design and implementation of highly extendable inflatable actuators, and demonstrates a range of scenarios that can leverage this modular building block.

LiftTiles：用于制作房间规模变形界面原型的建设性构建块

大规模变形界面具有巨大的潜力，但创建这样的系统需要大量的时间、成本、空间和努力，这阻碍了研究界探索超越人手规模的交互。我们引入模块化充气执行器作为构建房间尺度形状变化界面原型的构建块。每个执行器的高度可以从 15cm 改变到 150cm，由气压驱动和控制。每个单元成本低（8 美元）、重量轻（10 公斤）、紧凑（15 厘米）且坚固耐用，非常适合制作房间规模的形状转换原型。此外，我们的模块化和可重构设计使研究人员和设计师能够快速构建不同的几何形状并探索各种应用。本文有助于设计和实现高度可扩展的充气执行器，
