Touch Grass: voice dares that get you off the screen, running on-device with Gemma 3 270M

Описание и применение

Touch Grass — это PWA, генерирующая короткие задания на свежем воздухе на основе пользовательского ввода времени и энергии, используя модель Gemma 3 270M в браузере для обеспечения конфиденциальности и работы без сети.

Задача

Users often spend time on their phones without taking action, leading to inactivity and missed opportunities to be outdoors.

Результат

Touch Grass provides a privacy‑preserving, offline‑capable solution that turns idle phone time into actionable outdoor activity, with a single dare, photo proof, and streak tracking.

Рабочий процесс

• 1. User opens the PWA and speaks their available time and energy via the Web Speech API.
• 2. The app matches the input against a curated dare bank (dares.json) or, if a Hugging Face token is provided, generates a new dare with Gemma 3 270M via transformers.js.
• 3. The generated dare is spoken using the browser’s speechSynthesis and displayed in a dialogue ribbon with time/energy tags and a "prove it outside" button.
• 4. The user clicks the button, the camera opens via getUserMedia, captures a photo, and saves it as proof of completion.
• 5. The app records the completion toward a daily streak and updates the UI accordingly.

Доказательства

Touch Grass — say how much time and energy you've got, and it gives you one short, concrete dare to go do outside.

Источник

It's a PWA: install it, and after the first load it keeps working with no signal, because the shell and the model are both cached by a service worker.

dare generation runs on-device with gemma 3 270m via transformers.js, not a hosted api

Источник

The app is a static site, no build step.

Источник

Camera proof uses getUserMedia + canvas, with a defensive timeout — confirmed by hand that getUserMedia can hang indefinitely on a device with no camera rather than reject, which otherwise traps the UI with no way out.
