Visolve for checking colours and

Visolve showing colours of a logoThe 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.

Free Apps to assist with colour deficinecy issues in a pharmacy lab, with graphs and dissection

Here are some useful, free applications I came across for a needs assessment I have just completed.

colour blind assistantColorblind 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 appColor 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.

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

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.

Colour filters come to iOS 10

colour tint iOS 10Even though you could have colour filters on the Android and your desktop it has only been possible on the iPhone and iPad since the introduction of iOS 10.  These filters can be useful for dulling the screen, offering different choices of colour overlay for those with colour deficiencies or visual stress.  Go to Settings > General > Accessibility > Display Accommodations > Colour Filters. Turn them on and there is a choice of filters with the names of different colour deficencies such as Protanopia Red/Green filter.  Go to the bottom of the list and there you will find the colour tint that allows you to choose a hue and the intensity to suit your preference.

These filters have also been exciting star gazers as they provide a form of night vision according to Dave Mosher from Business Insider UK. 

f.lux and eyestrain – cool colours for the day and warm for the evening.

screen view of tintIf you are struggling with eye strain, because of screen glare, then the application ‘f.lux‘ may help you. The software changes the colour temperature of your screen based on the time of day. Daylight has a considerable amount of blue light; whereas sunset and late evening have much warmer tones. F.lux changes the screen from daylight settings to sunset or late evening settings. The application has a basis for its development within research – the negative impact of blue or day light on a person reading at night.

I downloaded the application and have already found it has had a positive impact on my eye strain. The initial setup did not take long but the changing of your location can be a bit clunky and you will need to check the longitude and latitude of your location. I’d recommend just typing the name of the village, town or city that you live in into Google asking for the longitude and latitude. Once setup the application runs unobtrusively in the background.

I would still recommend running f.lux in conjunction with altering your screens brightness or contrast. The application also has a feature that enables you to override the settings temporarily in case you need to do colour work – graphic designers, reprographics and commercial print companies will need to take note.

Free for Windows.(also available for Mac, Linux , and iPhone/iPad)

Here is some more information about eyestrain and computer screens from Wired

Extra note

“‘During the daylight hours, f.lux keeps your monitor relatively cool with a default color temperature of 6500K. Your brain tends to associate blue light with daylight. At night, f.lux dials down the color temperature to a warmer, more yellow glow (3400K). You can also choose from presets (Candle, Tungsten, Halogen, Fluorescent, and Daylight) or adjust the settings to another specific preference. In general, the yellower the light, the less straining it is on your eyes’”

Screen Adjuster for Android that adds a tinted overlay

I’ve found that Screen Adjuster for Android works well at tinting and adjusting brightness of the screen. Screen Adjuster allows you to change contrast, brightness and colour of the screen really quickly and easily.
However, working with the app can be very frustrating when you want to move the sliders near the edge of the touch screen.  The swipe gesture may not always respond.   Otherwise the app is free and easy to use and can even dim the screen below the system settings.

Screen Adjuster runs on Android 2.2+ and is on Google Play – there is a version that costs 0.73p that comes without the advertisements.
