AB Electronic apppliances are increasingly a part ofour everyday lives. In particular, mobile devices,with their reduced dimensions with power rivalingdesktop computers, have substantially augmented ourcommunication abilities offering instant availability,anywhere, to everyone. These devices have becomeessential for human communication but also include amore comprehensive tool set to support productivity andleisure applications.However, the many applications commonly availableare not adapted to people with special needs. Rather, mostpopular devices are targeted at teenagers or young adultswith excellent eyesight and coordination. What is worse,most of the commonly used assistive control interfaces arenot available in a mobile environment where user'sposition, accommodation and capacities can vary even   widely.To try and address people with special needs new  approaches and techniques are sorely needed. This paper  presents a control interface to allow tetraplegic users to  interact with electronic devices. Our method uses  myographic information (Electromyography or EMG)  collected from residually controlled body areas. User  evaluations validate electromyography as a daily wearable  interface. In particular our results show that EMG can be  used even in mobility contexts.
