Web camera based Eye tracking and

Head tracking ADE

CMPT480Term ProjectYichen DangNov 28,2012

For me:

Introduce a technology for painting without hands requirement

Deeper understanding of eye tracking and head tracking fields

For the field of accessibility: Help with people who has difficulties in moving

hands Introduce technologies that are cheap and

require least accommodation from users

Why my ADE is important

In 1800s, initial methods for tracking the location

of eye and head involving direct mechanical contact with the head or eyes.

In the 1940s, Shackel and Mackworth developed the concept of head-mounted eye tracking systems.

In the 1970s, Monty discovered that multiple reflections from the eye can be used to dissociate eye rotations frees eye tracking from head movement

Background

In recent years, infrared or near infrared

camera based systems to detect eye movements are introduced.

Lately, more advanced software to perform eye-tracking and head-tracking control have been introduced, which only require a web camera and can work under normal lighting rather than infrared lighting environment

Background

Read more materials about eye tracking

and head tracking technology Go over existing user lab ADEs, and create

a structure for my ADE Introduction Video What to Do What to Hand In

Project Milestones - Design

Create introduction section of my ADE Search good ADE videos Search good software Create instruction on software download,

installation, and configuration Developing activities in my ADE Create questions

Project Milestones - Construct

Find users to test ADE Conduct user testing Analyse users’ feedback Improve my ADE based on users’ feedback

Problems Finding a user with disability in hands

movement to test my ADE Creating a web page

Project Milestones – User testing

Result

In- class Demo

Head Tracking Software Demo

Test whether my ADE is informative Test whether the eye tracking and head-

tracking software is effective Test whether the eye tracking and head-

tracking software is easy to use Test whether the eye tracking and head-

tracking software is efficient

Evaluation Goal

Evaluation process:

Pre Session questions Task Session Post Session questions

5 Participants with different characteristics

Evaluation

Before experience ADE, most of my participants

think the eye-tracking and head-tracking require using special functional devices

For question that to describe situations where eye-tracking and head-tracking are useful, after experience my ADE, all participants mentions some or all tasks that they have preformed in my ADE.

Two participants suggest more videos should be included in my ADE.

One participant suggest more history information should be included in my ADE.

Result and Analysis Descriptive

data

The average rate of uses’ expectation has been met

by my ADE is 6.2/7 The average rate of ease of use for head-tracking

software is 6.2/7 The average rate of ease of use for eye-tracking

software is 4.4/7 The average rate for head-tracking video is 6 The average rate for eye-tracking video is 6.4

Result and Analysis Quantitate

Data

The average number of head-tracking related

questions that are answered correctly is 90% The average number of eye-tracking related

questions that are answered correctly is 65% The average time spent on performing head-tracking

related tasks is 4.8 minutes. The average time spent on performing eye-tracking

related tasks is 4.4 minutes.

Result and Analysis Quantitate

Data

Provide a more detailed instruction for eye-tracking

related task, especially for the calibration part. In introduction section of my ADE, mentions that eye

tracking and head tracking helps with people who have difficulties in moving hands or fingers, interact with computers.

Add an Additional Information and videos section in my ADE to provide optional history information and more videos

Improvements

Good enough to be used Further improvement Further use
