Eyegaze Analysis Systems


WHAT DO PEOPLE LOOK AT?

The Eyegaze Analysis System is an instrument for measuring, recording, playing back, and analyzing what a person is doing with his eyes. It is used for both developing and running custom eyetracking applications and includes all the basic video equipment, computer hardware, and Eyegaze software and C/C++ development libraries necessary to build and run eyetracking application programs.

SYSTEM FEATURES

  • Calibration: Fully automated calibration is fast (15 - seconds), easy and long lasting.
  • Accuracy: Highly accurate and tolerant to many variations, such as pupil drift and head range variation - typical average bias error .45 degrees. Good tolerance to ambient infrared light and to high-speed head motion.
  • Remote Video Tracking: Unobtrusive and non-distracting with nothing attached to the subject.
  • Accommodates Most Human Eye Variations: Useable by 90% of the people who try it, functional with most glasses and contacts.
  • Binocular Eye Tracking: Tracks both of the subject’s eyes to increase gaze point accuracy by adjusting for head rotation.
  • Trace Suite: This suite of programs captures a subject’s gaze when presented with static or moving images or during computer operations. In addition to generating the standard data of our Analysis System, the user’s gaze and the stimulus are linked so they can be replayed and studied in depth. The observer can view the subject’s screen, eye images and gaze point in real time on a separate monitor.
  • Eyegaze Software Development Tool Kit: EgWin API - Eyegaze Function Library (DLL and import library), Gaze Tracking Demonstration Program (executable and C source code), EgTraceImage and EgTraceText Programs (executable and C source code), Fixation/Saccade Analysis Function (C source code), EgServer and EgClientDemo Programs (C source code)
  • NYAN Analysis Tool: NYAN is an analysis tool based on screen recording technology with synchronized gaze and mouse data. It can be used instead of the Trace Suite to analyze web pages and intranet applications as well as standard application software and still images. In addition to Gaze Video Overlay Playback, Scanpath Analysis and Area of Interest Analysis it provides a way to visualize subjective perception of individuals or groups of people by means of Attentional Landscapes technology. NYAN also provides group statistics and many export possibilities.

SYSTEM OUTPUTS

At each camera image sample, the Eyegaze System generates:
  • an eye-found flag indicating whether or not the eye is visible to the camera and thus whether or not a valid gazepoint is calculated,
  • x-y coordinates of the subject's gazepoint on the computer screen,
  • pupil diameter,
  • 3-dimensional location of the eyeball center within the camera field of view, an indicator of head location and movement, and
  • fixation and saccade analysis.

SYSTEM SOFTWARE

  • Eyegaze Software: (Eyegaze.dll), video camera interface, eye image processing, gazapoint calculationTrace Program (trace.exe), Calibration Program (calibrate.exe), Eyegaze Demonstration Program (gazedemo.exe)
  • Windows XP Professional

EYEGAZE ANALYSIS SYSTEMS


Eyegaze Analysis System

  • Mini computer
  • Runs all existing Eyegaze Analysis System programs
  • Expandable: will allow you to add on binocular eye tracking and wide field of view camera lenses in the future

Binocular Eyegaze Analysis System

  • Improved accuracy!
  • Provides two independent measurements of gaze point
  • Averaging of gaze points from both eyes gives you an improved estimate of gaze point
  • A 30% reduction in point-to-point error
  • Near elimination of roll error
  • Upgradeable to EyeFollower™

Eyegaze Analysis EyeFollower™

  • Accommodates all natural head motions during normal computer operation
  • Automatic Eye Acquisition – The EyeFollower™ automatically acquires the eyes when the user enters the workspace and it rapidly re-acquires the eyes when he returns his attention to the screen after turning his head away
  • Head Motion Volume
    • Side to Side: 20 inches (51cm)
    • Up and down: 12 inches (30cm)
    • Back and forth: 15 inches (38cm)
  • Head Speed: 8 inches/sec (20cm/sec)
  • Head Accelerations: 20 inches/sec (50cm/sec)
