Electrooculography-controlled Cursor

Abstract

People with motor disabilities or those with amputated limbs may lack the capability to operate a computer using a standard mouse. In today's world, the use of a computer is necessary for everyday tasks and the inability to use a computer can be a huge burden. For such users, an alternate interface could be used to operate a mouse that does not require the dexterity of the average human but instead uses eye movement for cursor control. This report introduces the design of such an interface that uses Electrooculography (EOG) to control a computer cursor. Our system measures EOG signals from the right eye and were used to move a cursor to target points on the computer screen. Both vertical and horizontal movements were achieved and the cursor was able to be directed to both intermediate and extreme positions on the screen within an approximated 200 pixel region of error.
