Blink Reaction

Complete eight short rounds by blinking after the target visibly changes shape and color.

For entertainment only. Stop if repeated blinking or screen changes feel uncomfortable.

Private on-device game

Blink Reaction

Camera frames stay in this browser. Starting the game is the first time camera access is requested.

How to play

  1. Keep your eyes clearly visible during calibration.
  2. Blink after the target changes shape and color.
  3. An early blink restarts the round without a penalty score.

How scoring works

  1. Each cue follows a randomized waiting interval.
  2. Response time starts at the visual cue and ends when a blink reopens.
  3. Results include browser and model-detection latency.

Privacy

Camera processing happens on your device. WorkPose does not upload or store video, images, or hand and face landmarks. Results stay in this browser unless you separately choose to contribute the listed numerical values after the game.

Limitations

  1. Spontaneous blinks can create false starts.
  2. This is entertainment, not a cognitive, neurological, or medical test.
