Constructing a Low-Cost Mobile Eye Tracker


AAAAha I have found it. http://hcvl.hci.iastate.edu/cgi-bin/openEyeswiki/index.cgi?MobileEyeTrackerConstruction

I have a feeling that this is a Linux based project so it maybe pointless researching, but it has spured me on to keep looking for a cheap DIY solution.

This is another site that I found, that is linked to projections, and external devices to manipulate them. This guy has used the Projection Bombing, found on http://www.graffiti-researchlab.com.

"The simple explanation is that it's a cellphone paired to a mac using proprietary software, custom scripting and graphics, and then the results are displayed through a projector connected to the computer. The whole system is mobile and with the right projector/beamer, quite bright." (http://www.txtualhealing.com/how.html)

Just another cool way of creating an interactive projection space. I really don't want to have to code much, to create my project, and have been looking into different ways to createa simple but interesting environment, using projections. If I can manage to get hold of an eye tracking device, or can get hold of some information about to make one myself, that would be perfect.

L.A.S.E.R. research

I have been looking into making this L.A.S.E.R. tagging system but on a much smaller scale. Using the link above which contains full details of the equipment they used, and the application, I will recreate this project with my own projector, camera (borrowed from friend), and PC needed for the program they have written, that is able to track the green light from the laser. As far as I can tell the software provided can be manipulated with some simple changes in its code, to react to any colour of laser, and hopefully be made to do some other interesting things. Once I have bought a new bulb for my projector, and have my PC up and running once again, I will see if I can get this to work. I'll keep you posted.

L.A.S.E.R.







"In the spirt of GRL's and Eyebeam's open source beliefs, we are posting the code and executable
for the Laser Tag application online for you to download, dissect, reuse and hopefully improve. The code is
C++ and compiled in a super old school Codewarrior IDE for windows but it is oepnGL based and written
using openFrameworks which is a cross platform library for writing creative code. So it should be very
straight forward to run in Visual Studio, DevC++ or even xcode on a mac.

In its simplest form the Laser Tag system is a camera and laptop setup, tracking a green laser point across
the face of a building and generating graphics based on the laser's position which then get projected back
onto the building with a high power projector." (http://muonics.net/blog/index.php?postid=15)

Graffiti Research Labs have given a full open source and tutorial for making a similar lazer tagging system. After buying a new bulb for my projector and a lazer pen, I am going to experiment with this idea myself. It would be on a much smaller scale, and would make a really nice interactive environment, if there were several lazer pens for participants to write with. I assume that the software allows the control of colours and saturation etc aswell, so it could make for a really nice project.
