Abstract: The person affected with paraplegia normally has malfunctioning of limbs. Some of these patients can only move their head. Establishing a new channel without speaking and hand/arm motions makes life easier for patients and therefore improves their life quality. The objective of our project is to present the design and application of an accelerometer based efficient human computer interface (HCI). A head mounted accelerometer device is used to detect acceleration caused by head movements of the user in three axes and the provided data are collected by software on the target computer. The movement of the eye is detected by an eye blink sensor. Through this facility, the disabled person is able to control laptop, fan, lamps and other house hold equipment’s in his room. Our main aim is to make computer easily accessible by everyone including disabled people.
