Eye tracking and head tracking technology are two input technology are closely related to each other and provide a new powerful way for users to communicate with their computers, especially for users with paralysis and aphasia, who may often find it is very hard to communicate with a computer without using limbs.
This ADE will provide you with a quick introduction to using the web camera based head tracking and eye tracking techniques.
In this ADE your goal will be to navigate a user interface or a webpage and perform some required tasks by using each of head tracking and an eye tracking software.
At the end of this ADE, you will have experienced some of the difficulties of navigating user interface and performing tasks with head tracking and eye tracking programs, and be able to discuss the impact of using eye-tracking and head tracking as primary modalities in navigation and performing tasks.
Note: This ADE is intended to be completed using Windows.
1. To begin, please view the video http://www.youtube.com/watch?v=JSAdRJ6BDHc , this video demonstrates the application, ‘Camera Mouse’, which will be used for head tracking in my ADE. This demo shows how you can use Camera Mouse step by step. You can get the camera to focus on a feature on your face and then by moving your head control the mouse. Hovering over the link you wish to select for few seconds can make selections.
2. Download and Installation (Note: This software requires windows system platform, it works with standard features of typical laptops or desktop computers, and do not require special hardware or other software support).
A. Follow the link to download Camera Mouse 2013 Installer program to your computer. http://www.cameramouse.org/downloads.html , after you have successfully downloaded the program, you would be able to see a file named “CameraMouse2013Installer2013.exe” in the file directory where you choose to download this program. Double click this executable file and install “Camera Mouse” into one directory that you preferred on your computer. After installation finishes, you will see a green square icon on your desktop.
B. Now, download an application program, “Aliens and Paint”, which is a painting program that uses the Camera Mouse, follows the link: http://www.cameramouse.org/downloads.html .

Double click this executable file and install it into the same directory where you have just installed “Camera Mouse”. After installation finishes, you will see an icon called “EaglePaint” on your desktop.
3. Using Head tracking software: Now, double click “Camera Mouse” icon to open Camera Mouse program, and perform following activities.
A. Configuration. Click on Settings, then check the “Click” checkbox, and Set Radius to be normal, and set Dwell to be 3 sec. Also check the “Enable Double Clicking” checkbox to allow double clicking. As soon as Enable Double-Clicking is checked, a 2-click button will appear in the main Camera Mouse window, click ok and close the settings window.
B. Calibration. Look at screen and click on one feature on your face to start track (suggest using one eye of two eyes). After selection is down, slowly move your head for few seconds and then you will see the mouse moves on the screen corresponds to your head movement.
C. Navigation task. Control your mouse by using head, move mouse over the link: http://www.usask.ca/ and hover over that icon for 1 second to open this link in your default web browser, now use your head mouse to check what undergraduate programs are in University of Saskatchewan, and how many programs are currently in the Kinesiology college. After you have the answer, hover over the exit icon on your web browser to close it.
D. Open Painting Program. In Camera Mouse main window, hover over the 2-click button for 1 second to enable next clicking to be a double-clicking.
