What is MA?
Mobile accessibility (MA) refers to accessibility to application contents on smartphones, tablet PCs, and other mobile devices. An MA Certification Mark is granted for mobile device applications that have been developed in compliance with MA standards. The standards have been designed for easy access to mobile application contents for those with or without disabilities .
- The Internet user environment is rapidly shifting from PC to mobile devices, and the use of such devices by information access–challenged populations, such as the elderly and persons with disabilities, is also increasing. However, at the national level, attention to MA is still lagging behind WA. Efforts to improve MA are urgently needed.
- In the case of smartphones, the operating systems have improved tremendously with regard to embedded accessibility technologies. What this means is that, with improved accessibility in application software, anybody—persons with or without disabilities—can use mobile applications and enjoy the convenience of today’s "smart generation" without discrimination.
- Mobile device applications designed in compliance with the accessibility standards are not only useful for persons with disabilities, but they also contribute to improved user satisfaction among general population users because they greatly improve software compatibility and thus contribute to improved information exchange. In the long term, such applications will also contribute to higher application utility overall.
MA standards in Korea follow "Mobile Application Accessibility Guidelines," issued by Korea Telecommunications Technology Association (TTA).

Program development environment
There are two mobile device operating system (OS) platforms, iOS and Android OS. The two systems use different development (native) languages, which means that accessibility programs for each platform must be developed separately from the start. As for the screen reader program, the two platforms recognize and support different programs (iOS VoiceOver and Android OS TalkBack); thus, mobile content from an identical web source could be presented very differently on different readers.

User Input Method
Mobile devices do not come with a keyboard or mouse. Users must use a stylus or finger to touch the screen to operate or to input text into the device. In short, input method and operation of a mobile device is different from a PC. In order to implement mobile accessibility for persons with disabilities, software and application designers must also understand how the different users operate their mobile devices.
The following are the most common ways of searching contents by persons with vision disabilities.
|Search Method||Consecutive Search||Random Search|
|Description||Tab and Shift+Tab keys are used to select "next" and "previous" objects. This move uses one finger swiping from left to right.||When the finger touches the screen randomly, a screen reader gives a voice feedback. The user moves around the screen with one finger.|
