TrailWhisper: Keep Eyes on the Canopy. Phone in the Pocket.

说明与用途

TrailWhisper 让徒步者在不依赖网络和屏幕的情况下，实时获取附近野生动物的音频提示，利用开源边缘 AI。

问题

Modern hikers rely on smartphone apps that require constant internet and screen focus, causing a "Screen Trap" and loss of situational awareness in cellular dead zones.

结果

TrailWhisper enables hikers to receive real‑time, privacy‑preserving audio cues about nearby wildlife without relying on cellular connectivity or screen focus, demonstrating the benefits of open‑weight edge AI.

工作流

• 1. User puts phone in pocket and connects bone‑conduction headphones.
• 2. TrailWhisper captures ambient audio via the device microphone.
• 3. On‑device acoustic models (BirdNET‑Mini ONNX, MobileNet‑V3 BioAcoustic) analyze the audio in WebAssembly/WebGL.
• 4. The app synthesizes a 528 Hz Solfeggio tone and speaks a one‑sentence directional cue via window.speechSynthesis.
• 5. If the user looks at the screen for >30 s, a blur shield prompts them to put the phone away.
• 6. Sightings are stored locally in localStorage with SHA‑256 fingerprints and can be exported as JSON.

证据

We built TrailWhisper to reverse this. It is an offline‑first, zero‑screen nature trail audio companion powered by on‑device open‑weights AI.
