Wheel of Plush: A Co-Design Toolkit for Exploring the Design Space of Smart Soft Toy Materiality

Soft toys foster strong and enduring early childhood attachments, with positive effects extending into adulthood. Smart toys are vulnerable to exploits and can harm users. Bridging this contrast, pairs of smart objects, equipped with only simple sensors and actuators, may support peripheral and emotional awareness. At the same time, how exactly such pairs should negotiate the soft/smart spectrum to yield positive long-term impacts for people connecting through them is a design challenge. We engage this with the Wheel of Plush co-design toolkit. It enables 8x8 different sensor-actuator combinations in plush for co-designers to explore multimodal interactions for smart soft toy pairs connected over distance. We detail our design process and offer insights on designing a toolkit that combines artisanal plush material with simple sensors and actuators. With the Wheel of Plush, we contribute a toolkit for exploring smart soft toy materiality, data-frugal multimodal interaction, and opportunities for smart soft toy pair co-design.
