Imagination Arcade

Eight games you play with your whole body. The camera is the controller.

Stand about 6 to 9 feet from the camera so it can see you from head to knees (feet are optional). One player at a time; take turns and beat each other's records.

Video never leaves this device. The body tracker runs inside the browser. The first launch loads the tracker (about 10 MB), then it is cached. Works best in Chrome, Edge, Chromium, or Safari on a laptop, desktop, or a TV with a webcam.

About

Imagination Arcade is a family movement arcade: wireframe games, sound effects only, no music, no screens to sit in front of.

Privacy

The camera image is processed entirely inside your browser by an on-device body tracker. No video, images, or body data are sent anywhere. Scores are saved only in this browser's local storage. There are no accounts, cookies, or analytics.

Credits and licenses

Body tracking: MediaPipe Pose Landmarker (MediaPipe Tasks Vision 0.10.14) by Google, Apache License 2.0. The library ships with this site; the pose model is fetched from Google's public model storage on first run. ai.google.dev
Sound effects: four packs by Kenney (kenney.nl), all released under Creative Commons Zero (CC0 1.0): "Interface Sounds", "UI Audio", "Digital Audio", and "RPG Audio". Footsteps, coins, pots, cloth swishes, power-ups, zaps, pops, ticks, and chimes come from these packs, converted to small MP3 files and bundled with the site. Thank you, Kenney.
All other sounds: whistles, cheers, boings, animals, and the pong and brick tones are synthesized live in the browser with the Web Audio API. Original code, no recordings.
Line icons: animals, trees, mountains, trophies, and other little drawings are icons from Lucide (ISC license, copyright Lucide Icons and Contributors), embedded as path data and drawn as strokes so they match the blueprint look.
Smoothing: landmark jitter is tamed with the One Euro filter (Casiez, Roussel and Vogel, CHI 2012), reimplemented here.
Design: all graphics are drawn live as vector wireframes on a canvas. No images, no 3D, no generated art. Nothing flashes more than three times a second, and there is a Calm mode in Settings.
Typeface: whatever geometric sans-serif your device already has (URW Gothic, Century Gothic, Futura, or the system font).

Imagination Arcade is free and open source under the AGPLv3. Built by Kamsiob with Claude. Version 3.0.

Settings

Player size

Little is forgiving and slow (about age 4). Medium is for around 8. Big is tight and fast (10 and up).

Calm mode

Calm mode removes screen shake, halves particles, and softens celebrations.

Sound

Tracker model

Full is steadier. Lite is faster on slow computers. Changing this reloads the tracker.

Camera

Performance

Shows the tracker speed in the corner plus live body meters (run, steps per second, jump, stillness) so you can see what the game sees. If the speed sits under 20, switch the tracker to Lite.
