This is a project called FrabricKeyboard from MIT media lab. The fabric keyboard consists of multi-layer textile sensors machine-sewn in a keyboard pattern, and it detects different stimuli such as touch, pressure, stretch, proximity, and electric field. What I found interesting is that users can not only touch the interface to interact but also use non-contact gestures to play music. This project reminds me of another musical invention—Hand Roll Piano. With small size and low power consumption, Hand Roll Piano becomes a great portable musical instrument. Compare to Hand Roll Piano, FrabricKeyboard has made improvement in interaction design and music style that can be played.
