The EAS Monocular is a monocular eye tracker – it measures the gaze position of a single eye.It is particularly popular in research because of its low cost, reliability, and consistent accuracy and rich data output which is acquired with a high sampling rate.

Calibrating the EAS Monocular is fast and easy to perform. The calibration procedure takes approximately 10 seconds and only need to be conducted once. the EAS Monocular system also has the capability of remembering the last subject to use the devise enabling no further calibration procedures.

To achieve high gazepoint tracking accuracy, the image processing algorithms obtain very high resolution images of the eyes resulting in less than 0.4 degrees of angular error from the eye.

Reliability refers to the range of operational conditions under which the EAS Monocular is able to measure gazepoint data.

Dark and bright environments.

Operates on 90% of the human population!

The EAS Monocular accommodates a wide variation in the eye image, such as pupil size and pupil and iris brightness and it accommodates to most glasses and contacts. The system typically tracks 90% of the human population.

EYEGAZE EDGE® EYE FOLLOWER

This unique new technology solves eye tracking‘s tolerance-to-head-motion challenge once and for all. The EyeFollower accommodates all natural head motions during computer operation.

AUTOMATIC EYE ACQUISITION

The EyeFollower automatically locates the eyes when the user enters the work-space, and it rapidly re-acquires the eyes when he returns his attention to the screen after turning his head away.

ENHANCED FOCUSING TECHNOLOGY

LC Technologies‘ EFT achieves consistently high gazepoint tracking accuracy throughout the system‘s head-tracking volume.

Autofocusing telephoto lenses (rather than wide angle lenses) produce clear, high-resolution images of the user‘s eyes providing excellent gazepoint accuracy.

Cameras continually point and focus directly on the eyes, allowing the large volume of free head movement.

4-CAMERA-TRACKING

The system uses special cameras to track the head position and adjust the eye tracking cameras to the subject‘s eyes.

HIGH ACCURACY

The EyeFollower achieves its highly accurate 0.4-degree gaze point tracking accuracy throughout the whole operational head range. Even with high computer processing loads, the system samples data at a constant 120 Hz.

BINOCULAR EYE TRACKING

The EyeFollower tracks both eyes over the full range of head motion to enhance accuracy.

EASY CALIBRATION

The hands-free calibration is fast, easy to operate, and long lasting. The calibration can be saved and reused when working with the same subject again.

VERSATILE

The EyeFollower may be used with a wide variety of computer monitors, with a projection screen, with stereoscopic displays, or in a real-world, 3-dimensional setting with no monitor at all. 3-dimensional gazepoints are available for real or simulated 3D environments.

TECHNICAL SPECIFICATIONS

• Totally free head motion
• Automatic eye acquisition with face detection
• EFT (Enhanced Focusing Technology)
• 120 Hz sampling rate
• < 0.4 degree accuracy over the whole range of head movement
• Full range binocular eye tracking - both eyes
• Fully automatic calibration
• All-in-one system for starting right away
• Maintains accuracy if subject tilts his head to either side
