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
![Page 3: CMPT480 Term Project Yichen Dang Nov 28,2012. For me: Introduce a technology for painting without hands requirement Deeper understanding of eye](https://reader030.vdocument.in/reader030/viewer/2022032607/56649ed35503460f94be2f61/html5/thumbnails/3.jpg)
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

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

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.

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
