Spell™ is a smartwatch project that wants to bring airwriting as a way of enhancing interaction with digital devices. The motion sensing technology embedded in new smartwatches will enable the recognition of fast and light movements, produced with a flick of the wrist by writing letters in the air. With a short training, Spell™ will be able to recognize one’s writing style and let him/her airwrite quick replies to messages, notes, responses to the Smartphone’s digital assistant. Spell™ comes with an open development platform for new applications that lets air writing gestures communicate to Bluetooth 4.0 devices.
