Android Tablet
Options for the visually impaired
  • Non-visual feedback. Users can utilize built-in options that allow for non-visual feedbacking: TalkBack, KickBack, and SoundBack. To enable these, go to Settings > Accessibility > Enable Accessibility.
  • Carrier-specific apps. Apps4Android’s Android Accessibility Installer offers a host of accessibility options specific to carriers: Eyes-Free Shell provides one-touch access to Android applications. IDEAL Item Identifier is a barcode-reading app that enables users to take images of standard UPC and QR codes. Music lovers can also enjoy their collection on the go with the help of the Rock Lock music player.
  • Large text. People with sight problems can benefit from having the icons look darker and the text look larger with the BIG Launcher app.
  • Voice commands. Push the boundaries of artificial intelligence and make it work for you. Voice command functionality (Voice Actions) has been with Android for a long time. But, if you want extended features beyond Google Voice Actions, you can try Vlingo Virtual Assistant, which lets you use voice commands to perform tasks such as sending messages, dialing numbers, searching the Web, getting directions, launching apps, and many more. iris. (alpha) is another voice command app that you can try. It not only obeys voice commands but also allows you to interact with your phone using your voice.

Options for the hearing impaired
  • IM Clients and Texting. Google Talk and other messengers now offer accessibility features, and vibration can be used as a convenient alerting tool, too.
  • Text-to-speech. If you would like to converse with a friend who can’t read sign language face to face, the Text to Speech Toy app is your ally. It lets your device talk to your friends for you.
  • Google Translate. This smart tool can be utilized to reach out to others using sound, and if you communicate in multiple languages, switching between different tongues is no hassle.

Options for the mobility impaired
  • Enlarged graphics on interface. Large text is yet another useful tool, as users are able to easily toggle settings and select large icons with the use of the BIG Launcher app.
  • Easier navigation is coming. Potentially revolutionary work is being done with the Tecla Access app. With development still underway, this app aims to make Android devices and other major smartphones and tablets completely accessible using the mechanism that’s being used in navigating powered wheelchairs. While waiting for the commercial version to be released, an open-source Tecla Shield interface can be assembled for users.

Google Glasses will most possibly be used for accessibility functions for motor disabled people, as it comes with voice recognition and virtual reality functions.
