Yarbus eye tracker from the 1960s. History[edit] In the 1800s, studies of eye movement were made using direct observations. In 1879 in Paris, Louis Émile Javal observed that reading does not involve a smooth sweeping of the eyes along the text, as previously assumed, but a series of short stops (called fixations) and quick saccades.[1] This observation raised important questions about reading, questions which were explored during the 1900s: On which words do the eyes stop? For how long? When do they regress to already seen words? An example of fixations and saccades over text.
Edmund Huey[2] built an early eye tracker, using a sort of contact lens with a hole for the pupil. The first non-intrusive eye-trackers were built by Guy Thomas Buswell in Chicago, using beams of light that were reflected on the eye and then recording them on film. In the 1950s, Alfred L. Tracker types[edit] Applications[edit] Opengazer: open-source gaze tracker for ordinary webcams. ITU Gaze Tracker. 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.
The cameras that have been tested with the system can be found in our forum. We encourage users and developers to test our software with their cameras and provide feedback so we can continue development. The ITU Gaze Tracker is hosted in SourceForge. You can download the binaries or check out the code in the given link. In order to run the software, uncompress the zip file and double click on GazeTrackerUI.exe. You can also follow this screencast on youtube to help you in the setup process. TrackEye : Real-Time Tracking Of Human Eyes Using a Webcam. Introduction Eyes are the most important features of the human face. So effective usage of eye movements as a communication technique in user-to-computer interfaces can find place in various application areas. Eye tracking and the information provided by the eye features have the potential to become an interesting way of communicating with a computer in a human-computer interaction (HCI) system.
So with this motivation, designing a real-time eye feature tracking software is the aim of this project. The purpose of the project is to implement a real-time eye-feature tracker with the following capabilities: RealTime face tracking with scale and rotation invariance Tracking the eye areas individually Tracking eye features Eye gaze direction finding Remote controlling using eye movements Instructions to Run and Rebuild TrackEye Installation Instructions Extract TrackEye_Executable.zip file.

Here you will find all sorts of information, source code, and demonstrations of the stuff that we're currently working on at PyGaze HQ. We love to share our interest in science and technology with you! Most of this stuff is closely related to PyGaze, and gives a good idea of how you can use the toolbox. current projects PyGazeAnalyser Analysis of eye-tracking data without having to buy an expensive software package, or relying on a commercial party?

Mantis shrimp This isn't really a project, but more of an homage to a creature with a truly incredible pair of eyes. news Sun. 2 March 2014 We have added a new project, and it's a big one!

Right this very second, you are looking at a Web browser. At least, those are the odds. But while that's mildly interesting to me, detailed data on where users look (and for how long) is mission-critical. Web designers want to know if visitors are distracted from the contents of the page. Application developers want to know if users have trouble finding the important tools and functions on screen. The categories mentioned above do a fairly clean job of dividing up the eye-tracking projects.
For example, there are eye-tracking projects designed to work with standard, run-of-the-mill Web cams (like those that come conveniently attached to the top edge of so many laptops), and those meant to be used with a specialty, head-mounted apparatus. Many projects have a particular use-case in mind, but with the ready availability of Webcams, developers are exploring alternative uses suitable for gaming, gesture-input, and all sorts of crazy ideas.
