EyeTracking :the ITU Gaze Tracker

ITU Gaze Tracker
According to the development team, The ITU Gaze Tracker is an open-source eye tracker that aims to provide a low-cost alternative to commercial gaze tracking systems and to make this technology more accessible. It is developed by the Gaze Group at the IT University of Copenhagen and other contributors from the community, with the support of the Communication by Gaze Interaction Association (COGAIN).The eye tracking software is video-based, and any camera equipped with infrared nightvision can be used, such as a videocamera or a webcam.

Processing Easy Eye Tracker Plugin (PEEP)

Processing Easy Eye Tracker Plugin (PEEP)
It is, according to the development team, - "The probably easiest way on earth to develop stunningly looking eye tracking applications (and one of our most eye-appealing by-products we've created so far ... ;-)"

and an example of how to use the eye tracker in Processing available at Text 2.0 homepage:

---------------------------------------

Import eyetracking.*;

EyeTrackingDevice device;

void setup() {
device = EyeTrackingDevice.open(this);
}


void draw() {
ellipse(device.x, device.y, 10, 10);
}

X-box Kinect in Processing

to use X-box Kinect in Processing:

1) First, we need to download the Kinect driver for Windows:

Windows Driver/SDK Download:

2) Second, we need to download a library:

try the openkinect openkinect.org
by Daniel Shiffman
(At the moment, my library only works with Mac OS X (intel, 10.5 or 10.6 should both be ok)
