Inspired by Temple Grandin’s deep pressure device “Hug Machine”, this study aims to construct a therapeutic play space prototype with many tunnels and holes created through knitting. The size of the tunnels and the interactive pneumatic system, which includes sensors, can help users switch between different pneumatic modes more intuitively according to their needs, forming a variety of tension feelings. The project aims to provide a mixed sensory experience with enhanced feedback to help children with over- or under-response to sensory input. Collaboration across the fields of architecture, computational design (digital simulation and fabrication), and information (human-computer interaction), as well as with practitioners in the field of ASD-based therapies, is essential for this project.
