Trail Bingo: a hiking game whose photo check runs on your phone, with no signal
Описание и применение
Trail Bingo позволяет участникам походов идентифицировать живую природу офлайн, используя открытый модель BioCLIP, работающую в браузере Android, без передачи данных в сеть.
Задача
Hikers need an offline, privacy‑preserving way to identify wildlife while playing a game.
Результат
Trail Bingo enables offline, privacy‑preserving wildlife identification during hikes, using an open‑source BioCLIP model that runs locally on Android Chrome, with a 300 MB download and ~1.3 s per photo check.
Рабочий процесс
- Build a Card by querying iNaturalist for species within 10 km of the trail and time of year
- Download the 300 MB BioCLIP model on first launch (requires Wi‑Fi)
- Install the app to the home screen
- During the hike, tap a square and take a photo
- The on‑device model checks the photo against the card
- If confident, the square is marked Verified; if unsure, the top three guesses are shown and the user selects one to mark Confirmed
- After each check, a short fact card is displayed and dismissed with one tap
- Complete a row, column, or diagonal to win Bingo; complete all squares for Blackout
- Close the app and resume later; data is stored in IndexedDB and persists across restarts
Доказательства
The app asks iNaturalist what people have actually seen within 10 km of that spot at this time of year, and deals out a 3×3, 4×4 or 5×5 Card from it
An open model on your phone checks it against your Card, with no signal and nothing sent anywhere
The first launch downloads the photo check's model once (about 300 MB), so use Wi‑Fi. After that, building a Card needs signal, and playing doesn't.
On my phone, a photo check takes about 1.3 seconds.
