As seniors continue to make up a growing portion of today's digital society, it is important that they be able to confidently use their devices. We hope that the following how-to directions will be useful for librarians to help their patrons see text and images on their screens more clearly. This part discusses enlarging text and graphics and also making things on screens higher in contrast so that patrons can more easily see them.
Boost the Size of Icons and Text
With the release of iPhone 6, Apple finally joined the trend of manufacturing smartphones with huge screens. It included a handy way to enlarge text and icons to take advantage of the larger display — and happens to be a great way to improve visual accessibility for seniors.
Activate Display Zoom (distinct from temporary magnification) via Settings > Display & Brightness > View.
The view is set to Standard by default. Tapping on Zoomed will enlarge icons and text displayed system wide.
There is currently no way to permanently increase the size of icons on iPad devices without using temporary magnification.
To boost the size of text, go to Settings > Display & Brightness > Text Size and then drag the slider all the way to the right. To make it even bigger, go to Settings > General > Accessibility > Larger Text, then set the switch to On.
On Android devices, increased the font size via Settings > Display > Font size.
Unlike Apple, different Android hardware manufacturers each release their own proprietary versions of launchers — the components of the user interface related to the app drawer and home screens — and most do not include a way to permanently increase the size of icons.
GO Launcher is an excellent solution that you can download to overcome this. Its rich set of customization features includes a way to enlarge icons, making it ideal for elderly users though its typical users are younger.
Once the app is installed, to change the size of icons displayed on home screens, go to GO Settings > Personalization > Icon > Icon size and tap Recommended size (big). You can also drag the slider to play with the icon size until it looks good on the specific device.
To enlarge icons on the desktops of Windows devices, right-click anywhere on the desktop and go to View > Large icons.
To increase the system font size, go to Control Panel > Display and pick Medium (125 percent) or Larger (150 percent).
Make Text High-Contrast
Displaying text in high contrast is another effective way to improve readability for seniors. You can create this effect on iOS devices by going to Settings > General > Accessibility > Invert Colors and setting the switch to On.
On devices running Android 5.0 Lollipop and higher, activate color inversion by checking the box in Settings > Accessibility > Inverted rendering.
Enable high contrast on Windows computers by pressing the Windows key + U, clicking Set up High Contrast, and checking the box next to Turn on or off High Contrast.
Once high contrast is enabled, pressing Left Shift + Left Alt + PrtScr toggles color inversion on and off. If the senior is using a laptop, the Fn key may also be required in the key-press combination.
Additionally, you can install Google's High Contrast browser extension in Chrome to invert the colors of webpages, without the need to adjust system settings.
Once the extension is installed, enable the effect by clicking the icon next to the address bar and then setting the switch to On. Another way is to press Shift + Alt + F11.
