Hamsagayathri Journal on Computer Science 2347–6141 2 3 25 31 Three Axes Sensor, RS232 Serial Communication Paralyzed, Microcontroller, Visual Basic, Photo Sensor, IR Transceiver, Biometric Authentication This paper proposed an alternative for the use of computers by physically challenged and paralyzed people. It explains the basic idea of a Human machine interface which can be used to control the mouse using head-tilt [4], [5] and eyeblink [9]. The use of this mouse which is a emulating device does not required much energy since, it uses simple head movement and eye blink [1]. This device or Goggle uses three axes sensor for detecting the movement of the head according to which, the movement of the cursor can been done [8]. A photo sensor detects eye blinking [6]. The Infra Red (IR) transceiver consists of a 935nm IR transmitter and a phototransistor mounted on the same unit. This detects a strong increase in the reflected signal upon intentional long blink as compared to normal eye blink. This also uses palm vein pattern recognition as a biometric authentication for secured use of the computer. Palm vein authentication has a high level of accuracy since, it is located within our body and does not change over time. Hence, it cannot indulge in any kind of forgeries.
