Using social microvolunteering to answer visual questions from blind users
Erin L. Brady · ACM SIGACCESS Accessibility and Computing · 2015
Advances in technology have proven uniquely useful for blind people, but some visual questions they encounter still require human assistance to answer. We developed VizWiz, a smartphone application that connects blind people with visual questions to sighted workers who can provide answers. In order to make this app more sustainable and scalable, and keep costs from being passed directly to the users, we propose social microvolunteering, which allows people to donate their own time as answerers, but also access to a larger pool of answerers through their friends on social networking sites.
