Abstract: Users with severe motor difficulties may experience problems when interacting with traditional computing devices. This article addresses these problems by setting out a new method that involves interacting through binary sequences. A hardware and software system was designed based on this method. This system enables users to interact using binary movements that are triggered by clicking a single button. Comparative tests were carried out between the proposed method and Switch Control, an assistive technology embedded in iOS devices for the interaction of users with motor difficulties. In terms of typing speed, the results show that the proposed method proved to be more efficient in all the tested cases, and it was, on average, 22% more productive than the Switch Control.
