  • Part 4: Using keyboard shortcut keys to increase the font size in Microsoft Word – improving speed and workflow.
  • Part 5 (a): Using Immersive Reading tools in Microsoft Word to customise the font / text and listen to it spoken aloud.
  • Part 5 (b): Using Learning Tools in Microsoft Edge Browser to customise font/text, layout and hear it read aloud.
  • Part 6: Introduction to Microsoft Ease of Access Tools Display Settings – how to ‘Make text size bigger’, ‘Make everything bigger’ and how to adjust the mouse pointer size and colour.
  • Part 7: Using Windows Magnifier – how to use Windows Magnifier in combination with other Ease of Access Display Settings such as ‘Make everything bigger’ etc.

Seeing AI for recognising things and reading out what it has found!

Posted on by

According to Stuart Ball this free Seeing AI iPhone or iPad app has multiple benefits for those with visual impairments or who are blind.   It has been developed by Microsoft so has the ‘swiss army knife approach’ according to AccessWorld to telling you about the world around you.  It searches out light sources, identifies colours and money and describes them using text to speech.  It will recognise a person is approaching and offer a description.  Barcodes can be read and optical character recognition is used for documents etc.  Clear handwriting can be deciphered and scenes described.

Another college student called Veronica in USA has provided a very helpful Seeing AI review from a blind student’s point of view

Microsoft have produced a YouTube video about the Seeing AI app.

Thank you so much Stuart for providing this strategy.

overTHERE iPhone app for locating places in your locality.

screengrab of overthere appThe free overTHERE iPhone app has been called a ‘game changer’ by Stuart Ball as it allows places to be located via their signs by holding the phone in a horizontal manner.  You can then simply turn around on the spot and listen as businesses/shops are brought to your attention.  It also tells you how far away they are from where you are standing. According to the app developer it is an “accessibility app that helps blind individuals explore and interact with the surrounding environment by using virtual audible signs.”

 

“When the phone is held vertically you can use the screen or VoiceOver to review the list of signs around you. By selecting a sign from the list you can access details about a location such as its address, phone number, or web site.”

The app grew out of Smith-Kettlewell’s Virtual Talking Signs Project.

Claro Scanpen used with an exam paperI have found that Claro ScanPen works well with typed text and has the advantage of real time scanned conversions without an internet connection.  You can take a photo of the text using your smartphone camera and the app will scan the content and read it aloud using optical character recognition (OCR). Having had the text read out you can copy and paste sections into another app such as Notes.

Claro Software have created the a video showing you how to use Claro ScanPen with Guided Access

It works both on an iOS or Android phones and tablets and is available from the Apple app store and Google Play. The Android version is free and updates have fixed some of the glitches, the iOS version costs £6.99 outright at the time of writing.  This version has a restricted number of voices for different languages, whereas the premium version with an annual payment of £9.99 provides unlimited access to many different languages and option to have 10 free scans before paying as well as a 14 day trial.

Free Microsoft Office Lens speeds productivity

Taking an photo of the screen

Office lens is a free app available on an iPhone, Android and Window smartphone  that links to One Drive accounts and allows you to take photographs and put them straight into Microsoft Office applications. The really good thing about Office Lens is that when I take a picture of a presentation or whiteboard I can make sure it is exactly the right shape and is straight not set at an angle using the outline on the screen by selecting the document or whiteboard menu item.

Making sure the image is straight for OCR

That is really important if you are taking photos of text that you want to have read aloud later.  If they appear out of focus or at an odd angle you will not be able to use Optical Character Recognition (OCR), to have the image converted to text so you can use a text to speech or screen reader application later on.  Once you have taken your photo you choose which application you want to send it to and if this is Microsoft Word it will extract the text.  The other options are your photos on the phone, OneNote, OneDrive, PowerPoint and Outlook or your phone mail if you want to send it as an email attachment.  The app will also save it as a PDF.

The best thing I like about Office Lens is how it is linked to OneNote because I can collect all the images, notes and presentations, even photos of handwritten notes straight into my Notes folder and then I can search for them at any time,  as  I really have trouble remembering what I have heard in lectures etc and this process acts as a back up .

KNFB Reader app – Take a photo then have text read aloud

KNFB iphone app

knfbReader by Sensotec nv – View of the iPhone screen with a scanned document and output

I received a free version of the app through my role on the British Dyslexia Association’s New Technologies Committee and I love it!  For my own personal use (dyslexia rather than VI), I’ve historically relied on apps such as Prizmo or ClaroSpeak (with OCR addon). I started using this app a few months ago and for me this app is a big step up for two reasons:
1. Exceptionally fast user experience
2. Exceptional accuracy

1. Exceptionally fast user experience

The app’s purpose is essentially the same as Prizmo / ClaroSpeak (with OCR addon) / CapturaTalk.  However, the main advantage for me is that the time from snapping the photo and to starting to hear it being read aloud is a couple of seconds on my old iPhone 4S, and instantaneous on my iPhone 6.  They do this by:
a) Having an auto-read function, so as soon as it has text from the photo it reads aloud to you, without you having to press another button.
b) Starting to read before the whole page has been analysed.  As soon as it’s recognised the first sentence it starts to read that aloud.

The user interface is really nice – open the app, hold it above the page and press one button!  Then sit back and relax while the page is read to you.  This is a big plus for day-to-day use.

2. Exceptional accuracy

From my non-scientific playing with the app, the OCR accuracy appears to be at least as good as (and I think better than) ClaroSpeak’s OCR addon, and it is much better than Prizmo.

So money-no-object it wins hands down for me – an ideal example of an app that does only one thing and does it very well. Cost £79.99 for the iPhone
