Kexxu Eye

Kexxu Eye

Model 002.1 Kexxu Eye Tracking Glasses tracks one eye. The manufacturer also offers a separate version, currently in beta, that tracks both eyes, but with different specifications.

Kexxu Eye is a portable, head-mounted eye tracking system designed to record what the user is looking at while moving in a real-world environment. The device uses:

a camera aimed at one eye,

a camera that records the surroundings in front of the user,

a portable computing unit,

an artificial intelligence algorithm that detects the pupil position in real time.

A marker indicating the estimated gaze point is applied to the image from the ambient camera. The material can then be uploaded to the Kexxu Cloud environment to create heat maps, gaze graphs, and AOI (Area of ​​Interest) analysis. The manufacturer suggests applications in marketing research, product and interface testing, UX (User Experience) design, and the analysis of athlete behavior during sports.

Specifications

Model: 002.1 Kexxu Eye Tracking Glasses.
Device type: Mobile eye tracking glasses.
Tracking mode: Single eye – monocular system.
Data processing: Real-time on a portable computing unit.
Accuracy in the central field of view: Approximately 2° of visual angle.
Accuracy in the peripheral fields of view: Approximately 5° according to the manufacturer's technical data.
Measurement rate: 30 measurements per second according to the current product data sheet.
Alternative manufacturer value: The home page and technical data sheet state 40 frames or measurements per second. Therefore, the manufacturer's materials are inconsistent on this point, and the exact value should be confirmed before including it in an offer or purchasing process.
Surround camera resolution: 720p.
Surround camera field of view: Manufacturer claims 160°.
Surround camera: Increased sensitivity in low-light conditions.
Control unit connectivity: Wi-Fi. Battery life: up to 6 hours.
Battery: replaceable; the unit displays the current charge level.
Local storage: up to 16 hours of recording.
Gaze point preview: available in real time.
Captured images: eye image and image of the scene in front of the user.
Cloud-based analytics: heat maps, gaze plots, AOI, dwell time, and time to focus.
Head movement compensation: the manufacturer claims to use artificial intelligence algorithms to stabilize heat maps as the user moves.
