There are many barcode scanner apps available for both iOS and Android devices, but the standard for iOS and VoiceOver, is Digit-Eyes, for $9.99 on the App Store. This may be as simple as the name of the product, size, and weight, or it may also contain more comprehensive information, like ingredients. The Product channel on Seeing AI provides a barcode scanner that uses the camera to help locate the barcode printed on most product labels, and then read out the available product information. “What’s in this unlabeled can?” If you can’t read the printed label on a can, and it’s of a standard size and shape, it’s virtually impossible to tell what’s in it without some sort of labeling system in place. It scans a barcode that appears on most products that identifies what that product is, and other details about it, such as directions and ingredients. Prizmo is just under $10 and appears to be available only on iOS devices. After the photo is processed, text can be exported to a document and read with the screen reader. Like the others, Prizmo provides support for VoiceOver users to position a document below the camera viewfinder and prompts when to take the picture. PrizmoĪnother alternative OCR app for iOS is Prizmo. So try before you buy to make sure your next purchase provides all the accessibility features you need. The camera APP of some modern phones provides similar prompts when accessibility is enabled. The photo is processed, and the text saved into a digital text document that can be read by a screen reader. The user is then prompted to take the picture.

The software can identify the edges of the paper to be photographed and prompt users when all edges of a document are within the viewfinder. However, it works well with a screen reader and has some support for focusing the camera. Unlike Seeing AI, it was designed as a simple OCR app for both the computer and iOS – not specifically for visually impaired users. Office LensĪnother OCR from Microsoft is called Office Lens and it too is free. Although the app differs very little in the way it works, on either the iOS device or Android, the KNFB Reader is significantly less expensive on the Android-about $20 versus the $100 price tag on the iOS side. The “K” in this product name stands for Ray “Kurzweil,” still developing OCR products, and “NFB” for the National Federation of the Blind. Up until now, the go-to OCR app for both Android and iOS has been the KNFB Reader. For example, you can take a picture of a magazine article or printed recipe and have it read aloud by the smartphone. One of the most powerful categories of productivity apps available for visually impaired users on both smartphones and tablets is Optical Character Recognition, or OCR: software that enables users to take a picture of text, and have the app read it back with the device’s screen reader.
Short Text and Documents Channels are types of Optical Character Recognition or OCR. Other devices, like the Orcam 2.0 provide slightly different functionality which is self contained within the device and does not require internet connectivity to function. At the time of writing, Seeing AI still depends on a live Internet connection in order for its recognition services to work, because image processing is carried out on remote servers and not on your device. The Seeing AI app has several navigational “channels” that categorise the type of task required: Short Text Documents Product Currency Person and Scene. He opted to focus on the structure and components of the APP itself comparing it to some of the APPs it is competing with and the concepts that may be helpful to users as they decide which of these software tools is right for them.
Kelly did not write yet another review or tutorial for the APP, of which there are plenty.
PRIZMO GO 2.0 FREE
Kelly was among the people who downloaded the APP and tried it out with considerable interest, because as he said, it is a free app, and because it includes what many technology users with a vision impairment are seeking most in productivity tools: reading printed text object or obstacle recognition and labelling utilities, all packaged together in one APP! Within a few weeks from its release nearly a year ago, “techies” were giving glowing reviews to the Seein AI APP and podcasters were creating tutorials. Designed for the low vision community, this research project harnesses the power of AI to describe people, text and objects. A free app from Microsoft that narrates the world around you.
