TWEND is a hardware prototype that uses bending gestures as input for a mobile device and experimental setups that compare possible gestures with other, more traditional input methods in mobile computing. These will eventually result in guidelines for researchers and designers how to build bendable devices and show new interaction metaphors for computer user interfaces.
