EchoScape is an orientation and mobility (O&M) assistant built for blind and low-vision users. While you follow navigation, it watches the road at the same time, detecting the real positions of objects around you in real time and announcing them through spatial audio from their direction. It also warns of hanging obstacles at upper-body height such as signposts, tree branches, and protruding poles, with optional path passability alerts. From outdoor streets and crosswalks to finding building entrances and reading elevator floors inside the cabin, it supports every stage of independent travel. Four Core Capabilities Navigate and avoid obstacles at the same time Full voice navigation (turn prompts, distance announcements, off-route correction) never pauses, and environmental awareness never stops. Navigation handles where to go, while AI obstacle avoidance handles how to get there safely, and near your destination it can also help you find the building entrance. Elevator floor reading and saved ride records Inside an elevator cabin, point the camera at the floor display or button panel to hear floor changes and illuminated buttons. When exiting floor reading, save your frequent floors; next time you ride the same elevator, select a ride record to track floor changes offline via the barometer and hear an alert when you arrive. On-demand scene description, in and out in a tap Walking smoothly and something blocks your way? Tap once to enter scene description: it tells you the current street, your facing direction, and nearby landmarks, then describes what is ahead of the camera, such as construction, a barrier, or a clear path around. When done, it returns straight to navigation. Voice route book, smarter with every walk Map-planned routes are not always ideal for blind pedestrians, but a route you have walked yourself will always get you there. Save frequent routes and add your own voice notes along the way, marking gaps in railings, construction, or steps so they are announced automatically next time you pass. More Features Spatial audio and direction styles: stereo feedback for direction and distance. Choose between clock-face directions ("10 o'clock") and descriptive directions ("front left"), with system-matched distance units. Traffic light and crosswalk awareness: recognize traffic light states in the camera view, hear crosswalk alerts at intersections, and switch to roadside object alerts after crossing. Quick in-walk adjustment and smart battery saving: use the Adjust button to change object alerts, path passability alerts, scene description detail, and navigation frequency on the fly; detection pauses automatically when the camera faces away. Head gesture control: with supported AirPods models, a head tilt, nod, or shake operates the app; pair with a neck or chest mount to keep the camera facing forward. Multilingual accessibility: localized in 14 languages and deeply optimized for VoiceOver, with swipeable step-by-step route details. Privacy and offline: core obstacle perception and saved elevator ride records run on device; scene description works in the cloud or offline with a downloadable local model. Recommended Scenarios Daily commuting and multi-floor buildings: record your route and save frequent elevator floors once, then follow them with confidence every day. Going to appointments alone: get help finding the entrance on arrival and save the route for smoother future trips. Exploring unfamiliar neighborhoods: scene description combined with directional spatial audio helps you hear the world around you. Important Notice EchoScape is a mobility assistance tool. It cannot replace a white cane, a guide dog, assistance from others, or professional orientation and mobility (O&M) training. Elevator floor announcements are for reference only; always confirm before exiting and combine the app with careful judgment of your surroundings.
