Dharohar: an open-source AI audio guide that makes you put your phone in your pocket

Описание и применение

Dharohar – аудио‑путеводитель по историческим районам Индии, который удерживает экран телефона в черном режиме, использует геозоны для автоматического воспроизведения историй и кэширует аудио для автономной работы, тем самым уменьшая отвлечение от прогулки.

Задача

Users in heritage towns want to learn local history while walking without constantly looking at their phone screens.

Результат

Dharohar provides an audio‑first heritage walking experience that keeps users off their screens, uses geofencing for automatic story playback, caches audio for offline use, and enforces a no‑screen‑talk rule, thereby enhancing engagement with local history.

Рабочий процесс

• 1. User opens the app and grants location permission.
• 2. User taps "Walk where I am" to start a walk.
• 3. The app uses the Wake Lock API to keep the screen on and paints it pure black to save battery and avoid visual distraction.
• 4. The app orders nearby heritage sites into a route and creates geofences for each stop.
• 5. As the user enters a geofence, the phone vibrates and the pre‑generated audio guide for that stop plays.
• 6. If the device is offline, the service worker serves cached audio and data.
• 7. The walk continues until all stops are visited, with each stop played only once.

Доказательства

Dharohar is an audio guide for India's old city lanes that tries to get you to stop doing that.

Источник

The screen goes black. You walk. When GPS says you have reached the next stop, the guide starts talking.

Источник

Every stop is written and voiced before you leave, while you still have signal. A service worker caches the app and every MP3, so a temple courtyard with no network doesn't stop the walk.

Источник

The guide is forbidden from mentioning screens. No "on your map", no "tap here".
