An essential behavioural measure for researchers studying eye-hand coordination and the oculomotor system
With the Kinarm Gaze-Tracker installed in a Kinarm Lab, both motor and gaze measures are seamlessly integrated for effective experimental control and data analysis. There is no need to customize and coordinate multiple hardware solutions.
Features
- Designed for Kinarm Virtual Reality System; End-Point and Exoskeleton platforms.
- Workspace maximized with highest achievable accuracy.
- Can control experimental paradigm in real-time.
- An exponential increase in experimental possibilities.
Specifications & Information Sheets
System Specifications
- Sampling Rate: 500 Hz.
- Subject Setup: Requires a quick 5 point calibration.
- Resolution: 0.05°RMS; saccade resolution of 0.25°.
- Accuracy: ~0.5° with minimal head movement; up to ~1° with extreme head motion.
- Workspace Area: Elliptically shaped of ~50 cm x ~30 cm (~55° in the horizontal; ~40° in the vertical); the range does not cover the entire Virtual Reality workspace which is much larger (e.g. In the End-Point 76 cm x 44 cm); the gaze-tracker is centered in the middle of the Kinarm Lab workspace to optimize the range.
- Recovery from Loss of Tracking: Fast recovery through use of target sticker.
Infrastructure Needs
- Electrical requirements: can run from the same circuit at Kinarm Lab.
- For North America: a surge protector is provided.

Basic Researchers
- For those studying eye-hand coordination, gaze-tracker operation is fully integrated into the Kinarm Lab providing trouble-free calibration and operation through Dexterit-E.
- Gaze behavioural data is synchronized with the Kinarm data and available for further analysis using the Kinarm data upload scripts.
Clinical Researchers
Clinical Researchers
- The gaze-tracker allows the head to move freely/naturally which is especially important in clinical research.
- Collecting and analyzing gaze data can be finnicky; its not recommended unless you have experience with gaze-trackers.
Clinical Applications
Kinarm Gaze-Tracker integrated into an Exoskeleton or End-Point Lab helps researchers better their findings in:
Stroke
Investigate the relationship between impairments in upper limb and eye movement
TIA
Identify non-transient impairments and monitor recovery
mTBI
Discrimination of subtle, but statistically significant impairments not detectable by manual observation
