HMOS: Head Control Mouse Person with Disability

This paper presents an idea to build a human machine interface for disable persons. The purposed idea is very economical and useful for those disable persons who cannot use their hands to control computers.The main focus is to control the mouse through their head movements by using head-tilt sensor and air blow sensor. The system uses dual axis accelerometer based tilt sensor for detecting the movement of the head which is mounted on the headset and clicking of the mouse is activated by the 2 air blow sensor which are placed near the mouth to detect the left and right click of the mouse from the effect of the air blow in to the sensors. Since the device relies only on the user?s head and air blow, so it can be used easily without requiring too much energy neither in the head movement nor in the air blow for clicking. This system encourage the disable person to start their independent professional life
