Description of App: 

VizWiz lets blind users recruit remote sighted workers to help them with visual problems in nearly real-time. Users take a picture with their phone, speak a question, and then receive multiple spoken answers.
 

  • VizWiz Social combines automatic and human-powered services to answer visual questions for users with visual impairments.
  • VizWiz Social is an iPhone app that allows blind users to receive quick answers to questions about their surroundings. VizWiz Social combines automatic image processing, anonymous web workers, and members of the user's social network in order to collect fast and accurate answers to their questions.

Accessibility Comments: 

This app requires both a camera and an internet connection to work, so although it is billed as working on the iPhone, iPod Touch, and iPad, you'll need to use an iPod Touch 4G or an iPad 2 (devices with cameras) if you are not using an iPhone. This is different from oMoby and Noogle Noggles (now no longer available), because you can speak a question about the item you take a picture of. This may also mean a slightly longer wait for a reply while the app is "processing". (My tests on identifying canned goods were answered through IQ Engines rather than crowd sourcing.) Be sure to read through the tutorial on the VizWiz website.

VoiceOver Performance: 

VoiceOver reads all page elements.

Button Labeling: 

All buttons are clearly labeled.

Usability: 

The app is fully accessible with VoiceOver and is easy to navigate and use.

Other Comments: 

Unlike oMoby, this doesn't save a history of results, but you can ask specific questions. This is a free app that appears to be available internationally. It was developed by the Rochester Human-Computer Interaction group (ROCHCI), and you can read more about the scholarly aspects of this project at the University of Rochester web page for this project: http://hci.cs.rochester.edu/vizwiz/
