Project Summary

Eyes base Electric Wheel Chair Control: EBEWC is the proposed project. The proposed EBEWC is controlled by human eyes only. Therefore disabled person can control the EBEWC by themselves. Most of the computer input system with human eyes only consider in specific condition and does not work in a real time basis. Moreover, it is not robust against various user races, illumination conditions, EWC vibration, and user's movement. Though experiments, it is found that the proposed EBEWC is robust against the aforementioned influencing factors. Moreover, it is confirmed that the proposed EBEWC can be controlled by human eyes only accurately and safely.

Project Objectives

The existing computer input devices such as keyboard, mouse, and the other input devices have been used to interact with digital instruments. These computer input devices cannot be operated by handicap persons. In this project a computer input device by human eyes only is proposed for handicap person and also for wearable computing.

Project Implementation Method

The problem of the utmost importance of a proposed EBEWC system is the robustness against different user types, illumination changes, user's movement, vibration, and accuracy. In order to consider these as vehicle system, if the user changes, the system should be works without any input parameter changes. In accordance with EWC movement, illumination condition may change. Also, disturbances due to EWC vibration is potentially problem. In the conventional EWC control system with human eyes only, camera is mounted on EWC. This may cause a vulnerable when EWC is vibrated. Also, when user moves their head, gaze estimation is difficult. Furthermore, illumination condition may change during EWC movement. The proposed EBEWC system utilizes IR camera which mounted on user's glass. This way will eliminate problems of illumination changes, user's movement, and EWC vibration. Furthermore, the pupil detection based on pupil knowledge will improve the robustness against different users.

Benefits of the Project

It allows user movement: User can move during using the proposed EBEWC system in directions in the allowable distance of which the camera mounted on the glass acquires user face,

It does not require any calibration process before using the proposed EBEWC system,

It is robust against immunization changes, additive noises, vibrations to the EWC, user nationality (different color of eye as well as skin, size, and shape of eye), eyelid influence, and shade and shadow,

Pupil center detection accuracy for the acceptable angle range is almost 0.2 degree,

Even if pupil center is not detected when user close eye, gaze location is estimated with the knowledge of previously detected pupil center location.

Technical Details of Final Deliverable

The proposed system will be tested by several users with different race and nationality. The experimental results with the proposed eye gaze estimation method will be compared to wellknown adaptive threshold method and template matching method. Also robustness against illumination changing, noise influence, vibration, and accuracy has been confirmed.
