StrideQuest: Touch Grass, With a Little Help From On-Device AI

说明与用途

StrideQuest 是一个本地优先的 PWA，将散步转变为小型探险，使用浏览器内的 AI 对自然物体进行分类，并将数据本地存储，以鼓励真实世界的探索。

问题

Users spend excessive screen time; need an app that encourages outdoor activity while still leveraging AI for discovery.

结果

StrideQuest demonstrates that open‑weight models and web standards can power a privacy‑first, local‑first outdoor scavenger hunt that rewards physical exploration instead of screen time.

工作流

• Select a quest from the dashboard
• Step outside and pause the phone to photograph a target item
• Use the camera viewfinder to capture an image
• The in‑browser AI model classifies the image and suggests matches
• Save the observation to the local field journal
• Earn XP and unlock badges as you complete expeditions
• Review expedition history and telemetry offline

证据

StrideQuest is a local-first outdoor scavenger-hunt PWA for the DEV Hacktoberfest Week 1 Touch Grass challenge.
