The Visolve webpage or download allows you to check to see if colours are sufficiently distinguishable from each other. This can help those with colour vision deficiency or colour blindness. You can upload an image and it will provide you with the original view and other selected options such as Red-Green transform, Blue-Yellow transform, Saturation increase, Red, Yellow, Green or Blue filter and with added hatching.
Visolve is also available as an app for iPhones or on Windows and Mac.desktop computers.
Here are some useful, free applications I came across for a needs assessment I have just completed.
Colorblind Assistant – PC – Hover mouse over pixel in any running application – Excel/Powerpoint/PDF/Word etc, and the program displays the colours name.
“Colorblind Assistant is free software that instantly picks the color from the mouse pointer, providing you with a written name of the color, as well as other useful data such as RGB values and bar graphs, brightness and saturation.” It is available as an Android app on Google Play.
Color ID Free – iPhone and Android – Point phone or tablet device at any object and software displays name of currently viewed colour.
“Color Identifier uses the camera on your iPhone or iPod touch to speak the names of colors in real-time. It’s an Augmented Reality app for discovering the names of the colors around you!”
My student was a Pharmacology student who was having difficulty with graphs, lab equipment, dissection. Tested the phone app with various items I had around, and it was very good. As it is on a portable device, it is ideal for lab/field work.

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.
In MS Office programs you can get instant access to text to speech via the ‘speak’ button by using the Quick Action toolbar in Word and other Office programs. Go to File > Options > Quick Access Toolbar > Choose All Commands from the drop down menu > scroll down to Speak > add
“Immersive Reading Tools which were originally available in OneNote (and required a download) are now available in Office 365 – Word Online and OneNote as standard – no installation required. It’s also cross platform so will work on a Mac with Safari browser.
To access the Learning Tools in Word Online or OneNote Online, log into your account, open Word or OneNote, go to the View menu and click Immersive Reader.
• Read Aloud—Reads text aloud with simultaneous highlighting – although no option (that I can see) to change the voice. Still, the voice is ‘okayish’.• Spacing—a range of spacing options to help declutter pages. • Syllables—Shows the breaks between syllables to enhance word recognition and decoding.• Parts of Speech —Supports writing instruction and grammar comprehension by identifying verbs, nouns and adjectives.
Immersive Reader also has options to change the page colour, font size, style etc. ”

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
One of the easiest ways of checking for the spelling of a single word when on the move and not requiring a whole document to be spell checked is to say the word into a smart phone or tablet. As long as you have one of the fairly recent versions of Android, iOS iPhone or iPad or Windows, they all have built in speech recognition. I am showing an example of how it works on an iPhone with Siri and this iOS5 hot tip has been on the web since 2012. There is an Android tutorial on using Speech to Text and one for Windows Surface speech recognition
I said to Siri – “spell /filosofical/” (spelt as said) – It not only repeated the word back to me with text to speech, but also gave me the correct spelling and dictionary definition. If I just said the word it gave me the text to speech version back and a collection of links such as the word in Wikipedia.
