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. Settings to be Done to Perform a Good Tracking Settings for Face & Eye Detection Settings for Snake History
Free Eye Tracker API for Eye Tracking Integration The S2 Eye Tracker supports an open standard eye-gaze interface. The interface uses TCP/IP for data communication and XML for data structures. Our vision is to see this API adopted by many eye tracker developers, providing application developers a standardized interface to eye gaze hardware. For now this easy to use and free eye tracker API provides a simple way to interface with the S2 Eye Tracker. The S2 Eye Tracker API requires no software download whatsoever. The free eye tracker API is available to existing customers. Download: Open Eye-gaze API Version 1.0 The S2 Eye Tracker API is extremely flexible. Currently, we have example source code for C, C++/MFC, C++/CLI, C#, Python and MATLAB. The S2 Eye Tracker (and its older S1 predecessor) smoothly works with MATLAB.

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. In order to run the software, uncompress the zip file and double click on GazeTrackerUI.exe. The user's guide to run and configure the ITU Gaze Tracker can be downloaded from here (PDF document) The requirements to run the ITU Gaze Tracker are:
actionscript 3 - Flash library for eyes tracking Inexpensive or Free Head & Eye Tracking Inexpensive or Free Head & Eye Tracking Software For individuals that have lost the ability to use a standard mouse to control their computer, there are several low cost or no cost alternatives. It seems these methods work best when the target areas (the spots where you click) are larger, requiring less precise movements. To move the mouse around the screen without using your hands, you need to have software and a tracking device. Head tracking software to move the mouse around the screen:

Weekend Project: Take a Tour of Open Source Eye-Tracking Software 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. 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. Tracking Eye Movement With a Webcam On the inexpensive end of the hardware spectrum are those projects that implement eye-tracking using a standard-issue Webcam. OpenGazer is by far the simplest such project to get started with. Looking Ahead
Eye tracking Scientists track eye movements in glaucoma patients to check vision impairment while driving. Yarbus eye tracker from the 1960s. History 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. This observation raised important questions about reading, questions which were explored during the 1900s: On which words do the eyes stop? An example of fixations and saccades over text. Edmund Huey 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. In the 1970s, eye-tracking research expanded rapidly, particularly reading research.
play.blog2t.net » Realtime Terminator Salvation "Machine Vision" fx Have you seen Terminator Salvation yet? There's a bunch of cool visual effects developed by Imaginary Forces, it shows the world as seen by machines. There's a lot of object tracking going on there, I was thinking whether I could recreate the whole thing just in pure AS3. And, well, here's the result (which I am actually very proud of) ;-) Click image to activate, wait for the video to buffer (1.6MB) press EDIT button to play with the filters (in full screen mode). Enable your webcam (if you have one) and play about with sliders and checkboxes – try if your face can be tracked too – but then watch for evil Terminators – they'll come and get you! This is a part of the whole video filter framework I am developing just now, the inspiration came from Joa Ebert's Image Processing library (as far as I know, he's cooking a complete rewrite). My approach is to make everything as much simple as I can. The face tracking is actually relatively simple, I will briefly describe each step:
Why facial recognition failed It’s a staple of TV dramas — the photograph of a suspect is plugged into a law enforcement database, and a few minutes later: presto! We have a match! Facial recognition for the win! Except the magic didn’t work in the case of the Boston bombers, according to the Boston law enforcement authorities. The surveillance society did a face plant. What happened? Acquisti explained to Salon what he thinks might be happening on Monday morning. The Boston police commissioner says that facial recognition software did not help identify the Boston bombing suspects, despite the fact that their images were included in public records databases such as the DMV. There are three or four potential hurdles that all types of facial recognition software face when we try to apply them in real time on a mass scale. The first is image quality. The second hurdle is the availability of the fine facial data on the identified faces that you already have in your existing databases. What’s going to change?
