Inspired by animal tails, RESTAIL aims to design a wearable and functional tail device that combines both physical capability and emotional-expression functions.
As physical capability function, the proposed device can be transformed into a consolidated state to support a user's weight as a portable chair, similar to a kangaroo's tail.
As emotional-expression function, the proposed device can help users express their emotions, which are realized by different tail-motion patterns. , similar to a cat's tail.
RESTAIL is useful in the context of our daily lives.
Theme Park. The large theme parks like Disneyland could adopt RESTAIL to release the fatigue in the long queues waiting for popular attractions.
Personalized Tails. It can be enjoyable to design a tail with personalized shape and movements.
Communication Support. The proposed device could express the wearer’s emotion in public usages.
