Ursa Blink
A clip-on camera puck that turns face, gaze, and expression into control — and doubles as a high-quality webcam. Vision inference runs on a nearby companion device over the local network, never the cloud and never your laptop's compute budget.

What it does
Blink is a small puck that clips to a laptop lid or monitor and plugs in like any webcam. It tracks your face, facial landmarks, gaze direction, and expressions, and turns them into live Relay input — another vision-based channel into the same amplifier as switches, voice, and gaze glasses.
It's also just a good webcam. The same sensor that drives input tracking serves normal video calls, so the device earns its clip-on spot even before the accessibility features — and the vision compute never touches the computer you're actually working on.
How it works
- The puck itself stays cheap and low-power: it captures frames and hands them off. The heavy lifting — face detection, landmark tracking, gaze and expression inference — runs on a separate companion device on your local network.
- Inference results stream back into Relay as ordinary input events, alongside every other Ursa device, rather than as a separate control surface.
- Nothing leaves the local network. Frames and inferences never touch a cloud server, and the host computer running Relay never spends its own compute budget on vision.
- Blink is a deliberate architectural departure from Specs' camera-free philosophy — intentionally the one camera-based product in the lineup, for users and situations where camera tracking is viable and preferred over EOG or photodiode sensing.
Blink is intentionally the one camera-based product Ursa makes. Specs exists precisely because many people don't want a camera pointed at them — Blink exists for the people and situations where that tradeoff is fine, and a camera simply tracks better. Both feed the same Relay pipeline; the choice stays with the user. See Specs, the camera-free counterpart →
