This article is the fourth in a five-part series dedicated to sharing what we look for when testing websites and mobile apps to identify the accessibility barriers that might affect people with certain disability types.
Physical, or motor, disabilities refer to any weakness or limitation that impedes movement. This can include, but is not limited to, partial or total loss of muscular control, coordination, or physical sensation, as well as pain and missing limbs.
Many people can't or don't use a mouse and instead navigate with a keyboard, keyboard emulator, or other input device. This can be along with or independent of assistive technology like screen readers. That's why keyboard accessibility is foundational to digital accessibility.
Achieving these checkpoints is critical to achieving digital accessibility.

Some people may need more time to click, type, and complete interactive tasks. They may also type in single keystrokes as opposed to typing simultaneous keystrokes to activate commands, which include commands for special characters, shortcut keys, and active menu items. When users with certain physical disabilities don’t have enough time to complete these tasks, it limits their abilities to do things such as filling out a form for submission. Examples of giving enough time for people with physical disabilities include providing mechanisms to:
There are numerous types of assistive technology that people with physical disabilities might use. In order for special devices or software to navigate and communicate content, accurate and adequate text alternatives are needed. This includes labels for any buttons or controls needing an accessible name available to be activated by tools like speech input.
There is a lot to consider when it comes to orientation, structure, and navigation. For display orientation, referred to commonly as portrait and landscape views, it's important that content is not restricted to a single view unless it has to be for some essential reason — this guideline can be critical for people with certain mobility disabilities who may not be able to rotate a device or may have their device mounted in a fixed orientation, but it is also something to consider for people whose vision allows them to view something more easily in a wider display, for example.
It's also critical that users aren't expected to rely solely on the physical orientation or location of content or a control. For example, asking website visitors to select the red button in the lower left corner is not adequate — information as to where a user currently is and instructions for performing any task need to be available in the code in order to be perceived and communicated by assistive technology, or can be linked to directly to limit unnecessary navigation.
For these elements to provide structural knowledge to everyone, however, they can't only be achieved visually — they must be programatically determined to be available to assistive technology. This means that when testing, something can't just look like a heading, for example, but must be an actual heading in the code.
Presenting navigation mechanisms in a consistent and expected way helps people become oriented with how to use a website and move around it. For example, a design that includes a hyperlinked logo in the same place on every page should make sure it always points to the same destination. Or, maybe there is a standard masthead of navigational elements — they should be consistently positioned and labelled for your users. WCAG states that any navigational mechanisms repeated on multiple pages should be positioned in the same order. The ability to skip content and navigate without using too many keyboard commands is another aspect to consider.
