It is designed specifically for the deep woods, remote mountains, and hidden valleys where cell service goes to die.</p> <p>You point your device at a strange mushroom, a set of animal tracks, or an unfamiliar berry. TrailSight analyzes the image, identifies the specimen, and provides critical context: Is this edible? Is it an invasive species? What bird makes that nest?</p> <p>How it gets people off the screen:<br> TrailSight features a "Pocket Mode." Once you snap a photo, you put your phone away. The local AI processes the image and uses local Text-to-Speech (TTS) to whisper the findings into your earbuds while you continue your hike. The screen is just the camera shutter; the actual experience happens in the world around you.</p> <p>It is built for hikers, foragers, amateur botanists, and anyone who wants to rediscover the wilderness without needing five bars of 5G.</p> <h2> Demo </h2> <p>Imagine a video playing here... 🎬<br> A dense, foggy trail in the Pacific Northwest. The phone screen clearly shows "No Service." The user snaps a picture of a vibrant orange mushroom on a rotting log, locks the phone, and puts it in their pocket. A few seconds later, an audio voiceover chimes in: "That appears to be a Chicken of the Woods. It is a choice edible mushroom. Notice the overlapping, sulfur-yellow shelves..." The user smiles, harvests a piece, and keeps walking.</p> <p>Live Demo / Docs: TODO</p> <h2> Code </h2> <p>The entire stack is built to run locally on a smartphone or a Raspberry Pi field kit.</p> <p>github 1Prototype1/TrailSight-TouchGrass</p> <p>Core components include:</p> <ul> <li> <code>vision_engine.py</code>: Handles local inference of the quantized vision model.</li> <li> <code>audio_guide.py</code>: The local TTS pipeline for screen-free feedback.</li> <li> <code>trail_memory.sqlite</code>: A local vector database that maps your discoveries to GPS coordinates (saved locally, synced only when you choose to).</li> </ul> <h2> How I Built It </h2> <h2> Why Does Open Innovation Matter? </h2> <h2> My Agent Session </h2> <h2> Prize Categories </h2> devchallenge hf26challenge
