TL;DR

Prophesee’s neuromorphic “event” cameras ditch full‐frame captures and instead only report pixel‐level brightness changes, slashing power draw (just 2 mW active, 16 µW standby) while pumping out >1 kHz updates with sub-1 ms latency. That combo makes them ideal for always-on AR glasses—boosting battery life, speed and even privacy (no full-image eye snaps).

At AWE the author tried out Prophesee’s eye-tracking demo (built with 7Invensun): a pair of IR LEDs + tiny event cameras mounted on specs, a quick three‐point paper calibration, and boom—the on-screen orange “gaze dot” nailed every gaze shift. Accuracy claims are <1° and it felt snappy and reliable, making these sensors a compelling contender for next-gen, low-power AR smartglasses.
