Perception Assist is an environmental awareness aid. It does not replace a cane, guide dog, professional navigation, or your own safety judgment.

Capabilities

One product, two natural ways to use it

Get a quick answer when you need to understand your surroundings, then move into a focused reading space when you want to continue.

Perceive as you move

Stay aware outside. Understand what is in front of you.

Walking Guardian, surroundings observation, text reading, and voice conversation help with streets, signs, menus, and nearby objects.

Start walking guard

Start walking guard automatically when the app opens, so it can watch for nearby hazards while you walk.

Observe surroundings

Double tap to run the current option. Swipe up or down to switch between Observe surroundings and continuous recognition.

Describe people

Captures a fresh image and describes only visible people, their positions, and visible appearance.

Text recognition

When you are seated or checking fixed text, use “Read text aloud”. The app watches the camera view, asks you to hold steady or adjust light when needed, then automatically chooses a clear still frame for cloud analysis.

Start voice conversation

Ask follow-up voice questions, such as what is ahead or where the tactile paving is.

Important Item Memory

Off by default. After you enable it, selected items seen indoors are saved locally as time and position text. Images, audio, and full questions are not saved.

Sit down and keep reading

Sit down and keep reading. See clearly and manage the whole document.

Reading Camera and the Assistive Reading workspace make photos, documents, and web pages easier to see, hear, find, and manage.

Reading camera

Magnify what is in front of you or align a page for automatic reading.

Open a photo or document

Choose what you want to read. Photos use Smart Photo Reading; PDF, Word, Excel, and web pages are extracted locally first.

Step outside and enjoy the sunshine and breeze at your own pace

Mount your phone at chest level and start Walking Guardian. Perception Assist adds spoken information through your earpiece, alongside your cane or guide dog, as you stroll through parks, city streets, or the waterfront.

Everyday uses

Once seated, read menus, newspapers, and documents at your own pace

Use quick text reading for short content, or open Assistive Reading to magnify, reflow, listen, and keep your place in longer content.

Text recognition. Point at a sign, menu, or package for a quick spoken result without leaving what you are doing. — Read it now and answer the immediate need

Accessibility and privacy

Accessibility runs through the interface. Data boundaries stay clear.

Accessibility support

The app supports VoiceOver. For hands-free use, pair it with a chest or necklace-style phone holder so the rear camera faces forward; such holders are available from mainstream retailers. The app also works alongside third-party navigation. Start your preferred navigation app, set your destination, begin guidance, and then switch to Perception Assist (Perceive World Assist) to stay aware of obstacles while following directions.

Everyday reading tools work locally first

Magnification, display, reflow, search, bookmarks, and notes mainly stay on your device. Image description and AI explanation use cloud services only when you choose them.

Safety guidance

Perception Assist (Perceive World Assist) is an assistive aid only. Always combine it with a cane, guide dog, or a trusted companion when moving around. Be cautious near traffic, stairs, elevators, or complex intersections, and confirm what you hear before taking action. Avoid depending solely on the app at night or in poorly lit environments.
