• COMPONENTS
   
• Eye/Scene Imaging System (Mounted on Baseball Cap)
• · Ultra-lightweight, miniature eye and scene imaging electronic and optical component assemblies generate eye and scene video images for virtually any subject.
• Pupil/Corneal Reflection Tracking Circuit Card (Installed in Computer Chassis)
• · Eye tracking processor tracks center of subject’s pupil and a reflection from the corneal surface and measures pupil size, all in real-time.
• Autocalibration Circuit Card (Installed in Computer Chassis)
• · Autocalibration processor calculates subject’s fixations with respect to scene being viewed. Real time fixation is represented as a cursor on operator’s scene monitor and may be output in serial format from the PC
• · Output data is in NTSC format and can be recorded with an external VCR
• Eye Monitor
• · 9-inch black and white monitor for viewing video from eye camera.
• Scene Monitor
• · 9-inch black and white monitor for viewing video from scene camera
• Computer System
• · Dell computer system includes computer chassis, color monitor, mouse, and keyboard.

• SPECIFICATIONS
   
• Imaging Environment
• · Fully functional under dark or bright lighting
• · Parallax-free scene imaging means that subject point-of-gaze calibration is accurate over full depth of focus

• · Wide range of subject acceptance: eyeglasses, sunglasses, contact lenses, drooping eyelids easily accommodated.
• · Ultra-lightweight of eye/scene imaging assemblies allows mounting to virtually any headgear. (Weight of eye/scene imaging assembly w/ cap: approx. 8.5 ounces)
• · Complete subject mobility while recording pupil size and point-of-regard information with respect to surrounding environment.

• · Pupil tracking methodology separates pupil from dark shadows or eyelashes in eye image
• · Resolution: 1500 units horizontal x 2200 units vertical
• · Built-in fixation monitoring and blink detection
• · Pupil measurements include horizontal diameter, vertical diameter, and pupil area

• · 60 Hz update rate (upgradeable to 120 or 240 Hz)

• · RS-232 serial interface for all eye data parameters

• · Point-of-regard accuracy typically <0.5 degrees over +/-25 degrees horizontal and +/-20 degrees vertical range
• · Extended range calibration procedure tracks eye movement over +/-40 degrees horizontal and +/-30 degrees vertical range

• · System set-up and subject calibration are both simple and flexible
• · Data collection and calibration procedures are performed from operator’s PC console
• · Subject calibration procedure typically takes less than 3 minutes
• · Stored data is in ASCII format for later retrieval, analysis, and exporting

• · Operator configurable software includes scrolling graph displays to view data
• · Recorded parameters such as raw data, velocity, or acceleration can easily be displayed
• · Automatically computes average, maximum, minimum, and standard deviation
• · Correlates subject fixations to objects within the viewed scene

• · 115/230 VAC, 60/50 Hz
