Understand surroundings outdoors and read what’s in front of you. Walking Guard, reading, voice chat, magnification and high contrast support blind and low-vision users.
Perception Assist (Perceive World Assist) is an environmental awareness and voice guidance assistant designed for blind, visually impaired, and low-vision users.
The app combines on-device visual detection, scene understanding, spoken feedback, and haptic cues to help users understand their surroundings more quickly. Even with weak or no network connection, on-device capabilities can provide basic environmental recognition and risk prompts. When a network is available, cloud AI can provide more detailed scene and object analysis.
Key Features
Outdoor risk recognition
Detects selected traffic signals, crosswalks, bicycles, cars, approaching vehicles, and other elements, then provides voice prompts for potential surrounding risks.
AI scene analysis
Uses advanced AI models to interpret people, objects, spatial layout, and visible text, making indoor and outdoor environments easier to understand.
Automatic detection mode
Open the app and it can start automatically, reducing complex operations and helping users enter an assisted recognition state more quickly.
Multilingual voice feedback
Supports multiple spoken languages, adapts to the system language or user selection, and allows speech rate adjustment.
On-device first, cloud assisted
Basic recognition is mainly performed on device and remains available with weak or no network connection. When online, cloud AI can provide richer scene descriptions and review results.
Accessible interaction design
Combines voice, vibration cues, and accessible interface elements to provide detection status, scene overview, operation guidance, and assistive feedback.
Privacy protection
Visual and audio data are processed on device by default. No account registration is required. Except when users actively use optional cloud-assisted analysis, the app does not store personal visual or audio data.
Usage suggestion
For a more stable recognition experience, use headphones, bone-conduction headphones, or a chest phone mount.
