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.

I really like OneNote as I can dump all my research into different sections and pages, grabbing things from the web. I can share them with colleagues which has been made easier now that OneNote can be used both off and online and there is a Chrome extension called web clipper. You need to have a Microsoft account and download the extension. The icon sits at the top of the browser and when there is something you want to keep for reading later you can choose to have the complete page or sections etc. OneNote has always been good at automatically capturing where the clip comes from with a URL but this method allows you to add to the information.
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.
Ready for exporting
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 .
I use coloured glasses when working with computers but our network has ssOverlay. which I can use if I forget them! You can select the colour you want from settings arrow and activate the overlay. It covers the screen completely and can be turned off and on from the bottom right of the taskbar. where a small yellow arrow can be seen. Right hand mouse and you can exit the program. It is very simple and easy to use.
ssOverlay (921Kb download )
“Very similar to Dark Screen, ssOverlay (the ss stands for Scotopic Sensitivity), places a coloured overlay onto the screen. The colour and transparency levels can be adjusted to suit the user.”

Evernote is the “most useful app. Good layout and easy to organise my notes and research. Able to synchronise with laptop. I can use a notebook for each of my modules. I find the ability to synchronise whatever I input on iPad with laptop. Excellent for storing notes which were made earlier, easy to find, no more searching through pages in books. Far superior to Notebook+ and Notebook. This app really met my needs.”
