When my friend first got an iPad, their first question to me was about how to use Apple’s Zoom screen magnification tool so that they could use their iPad with low vision. Since they use screen magnification software on their computer already, it was fairly easy to teach them how to open Zoom and configure different magnification settings, though I was surprised to learn that even though we both have low vision, we each had different preferred settings for screen magnification. Here are my tips for using the Zoom Magnifier on iOS and iPadOS with low vision.
There are a few different options for opening Zoom on iOS that all lead to the same program, though Zoom must be turned on in accessibility settings before using any of these shortcuts:
Zoom offers three different types of views for screen magnification, called zoom regions. Users can change which view they want to use by triple-tapping to open Zoom setting and selecting “choose region” or by changing the Zoom region in settings.
Options for Zoom views include:
In Pinned Zoom, the zoomed image is shown in a fixed area on the screen. By default, the docked lens is placed at the top of the screen, but this can be changed in settings to be on the bottom, left, or right sides as well. When enabled, the Pinned Zoom takes up half of the screen size and can be adjusted by tapping and dragging on the edge of the magnifier window.
The docked lens will follow the user’s gestures and touch input, though does not magnify the keyboard when Smart Typing is available.
In full screen, all of the contents on screen are magnified to the percentage set by the user. Just like in docked view, Zoom will follow touch input, and users can drag with two or three fingers to explore the screen.
With the Window Zoom, a magnification window will show up on the screen, and the user can drag it to their desired region on the screen, just like a magnifying glass. By clicking the “resize lens” option, users can adjust the size of their magnification window to be as large or as small as needed. Users do not need to set their magnification window size every time they open the Window Zoom.
Users can adjust the magnification power within Zoom by doing the following
Users can change the maximum Zoom level by opening accessibility settings and scrolling to the bottom to adjust the Zoom level using the slider. The maximum Zoom level available is 15x, though I set my maximum Zoom level to 5x.
The Zoom magnifier can be changed to have different color filters, including:
Users can also adjust display settings in the accessibility menu to invert the entire screen or apply other color filters.
Additional options for configuring Zoom include:
Some examples of how I use Zoom include:
Zoom magnification has helped me tremendously with being able to use my iPad for various apps and with following along with my reading and classwork in college. Knowing how to use Zoom magnifier is essential for people with low vision, and I hope that these tips will help users to learn their magnification preferences and use their iPad for displaying information in an accessible format.
