Project Introduction

Project Background

EOG - Based Glasses-Type Wireless Mouse For The Disabled is an assistive device that utilize biopotential amplifier in order to obtain a physiological signal due to eye movements thus feeding it to a decoder to move mouse’s cursor. Eye control is an alternative and complimentary input method to using a mouse or hands, and allows user to adapt your communication methods according to your changing needs.  Many people with severe disabilities usually retain intact their control capacity over the occulomotor system, so eye movements could be used to develop new human-machine communication systems. Furthermore, this type of interface would not be limited to severely disabled persons but could be extended to the whole group of persons with the capacity for controlling their eye movements. 

Project Statement

I started this project after wondering how to assist the disabled with only eye-motor coordination in communication and for them to be able to live independently and be exposed to current technologies. Paralyze patient are not able to move their finger or hand, but they can still move their eye. By taking that slight movement in account, signals are obtained via EOG and fed control system to move the cursor. 

Objective

• To design, construct, and test an eye-controlled method based on electrooculography (EOG) to develop a communication assist device for the disabled.
• To enhance communication between the disabled and their family members, medical practitioner, and their environment.
• To assist those with only eye-motor coordination, to live more independent lives and catch up with current technologies. 

    Scope of Project / Limitation

  EOG - Based Glasses-Type Wireless Mouse For The Disabled is a communication aid device. The crucial part of the system is the conversion of EOG output to mouse input signal.  Thorough research, experiments and result analysis have to be conducted on input/ output of EOG and wireless mouse in order to achieve the objective of the system. Motion artifact might cause error to EOG output thus affect the mouse input. Experimental research will be conduct by testing the interface early on with real users who come in contact with the interface on an everyday basis. The user interface design must take in account to ensure patient’s comfort.
