Abstract
Easy Input is a head-controlled keyboard and mouse input device for paralyzed users. This study describes the motivation and the design considerations of an economical head- operated computer mouse. In addition it focuses on the invention of a head-operated computer mouse that employs tilt sensors placed in the headset to determine head position and to function as simple head operated computer mouse. One tilt sensor detects the lateral head motion to drive the left or right displacement of the mouse. The system uses accelerometers to detect the user's head tilt in order to direct mouse movement on the monitor. The clicking of the mouse is activated by the user's eye blinking through a sensor. The keyboard function is implemented by allowing the user to scroll through letters with head tilt and with eye blinking as the selection mechanism. We constructed an interface system that would allow a sin-Wady paralyzed user to interact with a computer with almost full functional capability. That is, the system operates as a mouse initially, but the user has the ability to toggle in and out of a keyboard mode allowing the entry of text. This is achieved by using the control from a single eye, tracking the position of the pupil for direction, and using blinking as an input. As detection of eye motion proved too challenging, we built an accelerometer based tilt detector to determine head motion, so that, although not as applicable in this particular case, it might be used by a quadriplegic individual.
