Oculomotor & vestibular measurement · standalone headset
Saccade latency, convergence, pupillary light reflex, smooth pursuit, VOR, balance and reaction time — scored against each athlete's own baseline, with the raw eye-tracking trace kept for every session. Under five minutes on the sideline. Sixteen for a baseline. The clinician decides; the numbers are there when they do.
Illustrative trace. Every athlete is measured against their own recorded values, not a population curve.
Two modes
The same headset runs two batteries. One compares an athlete to their own pre-season baseline when a deficit is the question; the other compares them to their own best when performance is. Same instrument, same roster, different reference.
Against the athlete's own pre-season baseline
Four systems in under five minutes. Output is a finding — no deficit detected, deficit detected, significant deficit detected — for a clinician, never a return-to-play decision.
Against the athlete's rolling personal best
A harder battery for decision speed under load. No baseline needed; the first session sets the mark. Kept apart from recovery data so training gains never read as healing.
The battery
No composite wellness score. Each test returns a quantity you can read, question and compare across sessions — or reports unavailable, with the reason, when it could not measure.

The report
For every test, the report shows the measured value, the athlete's own baseline value, the result as a percentage of that baseline, and a colour band.
Sample
Generated by the software from a synthetic test athlete.
For the neurologist
Detector definitions, fixed across builds: PLR latency at 10 % of constriction amplitude on a median-filtered trace · saccade onset at 2° displacement after a 1–2 s random foreperiod, <80 ms excluded as anticipatory · pursuit gain from a least-squares fit of eye on target position, no differentiation · objective vergence break = filtered vergence lagging demand by ≥ max(3°, 20 %) for 0.3 s with hysteresis.
NuOptic Desk
Add athletes once. Tag the headset before each session; the tag is used once, so a result can never attach to the next person. Pull over USB. Open any athlete's report. Windows, Linux, Mac; the database stays on your machine, every pull is kept raw.
In the headset
A session runs in four stages. The examiner chooses the athlete and the assessment on the menu, then hands the headset over. The athlete presses START only once the headset is seated and comfortable, so nothing is timed against a fumbled start. Between tests the headset shows a neutral progress screen: no score, no colour band, no hint of how the last test went. When the battery ends, the athlete is asked to take the headset off and return it. No result, band or finding ever appears in the headset. The examiner reads them on the desktop after the pull.
The four panels below are drawn illustrations of those screens. Photographs from inside the headset will replace them after the first recorded sessions.
Limits
NuOptic does not diagnose concussion and does not make return-to-play decisions. It is a measurement instrument; its output supplements the evaluation of a qualified clinician under your institution's protocol. Not FDA cleared. Deficit scoring requires the athlete's own baseline under the same software configuration and response device. Intended for athletes 13 and older.
