Following these guidelines not only benefits users with visual impairments but also enhances the overall user experience.

Interactive features and navigation

Interactive features and navigation, being core elements of any mobile app, greatly influence its accessibility. Here are some guidelines to follow:

  • Controls and interactive elements for touchscreen devices should have a hit target of at least 44x44 pt — this dimension recommendation ensures that elements are easily tappable by users with varying levels of ‘hand-control’.
  • Gestures should be operable with a single pointer — meaning users can perform actions using a simple touch or mouse-click without the need for multi-touch or complex maneuvers.
  • Function triggers should not rely solely on device motion, allowing alternative methods such as single taps — ensuring accessibility for users who may have difficulties with motion gestures.

The navigational paths should be enhanced by the consistent placement of navigational elements, and features such as speech recognition can benefit users with physical disabilities by allowing voice control over navigation.

Tip: When considering the design and features of your mobile app, don't overlook the importance of accessibility. Incorporate guidelines from the outset to create an inclusive experience that accommodates all users, including those with disabilities. This proactive approach can prevent costly redesigns and promote a more universally accessible app.
