A large angle, low voltage, small footprint micromirror for eye tracking and near-eye display applications
Bibliographic record
Abstract
This paper introduces a micromirror device that enables a compact, low-power, high-speed, high resolution eye-tracking system that may be integrated within eyeglasses or heads-up-displays. We report a CMOS-MEMS that achieves a scan range of 65 degrees (optical) in one axis and 25 degrees in another axis. The device operates at CMOS-compatible voltages (0-3.3V) and currents (<;15 mA), and employs isothermal scanning to suppress thermal excursions arising from electrothermal (ET) actuation. The footprint of the device is 40× smaller than commercially available micromirrors, at a mere 750μm × 750μm. Although the eye-tracking system is intended to operate under quasi-static conditions, its 5kHz resonant frequency may also enable QVGA resolution in near eye display applications.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
