ABSTRACT
This demonstration presents EasySnap, an application that enables blind and low-vision users to take high-quality photos by providing real-time audio feedback as they point their existing camera phones. Users can readily follow the audio instructions to adjust their framing, zoom level and subject lighting appropriately. Real-time feedback is achieved on current hardware using computer vision in conjunction with use patterns drawn from current blind photographers.

Supporting blind photography
ASSETS '11: The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibilityBlind people want to take photographs for the same reasons as others -- to record important events, to share experiences, and as an outlet for artistic expression. Furthermore, both automatic computer vision technology and human-powered services can be ...
Evaluating existing audio CAPTCHAs and an interface optimized for non-visual use
CHI '09: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsAudio CAPTCHAs were introduced as an accessible alternative for those unable to use the more common visual CAPTCHAs, but anecdotal accounts have suggested that they may be more difficult to solve. This paper demonstrates in a large study of more than ...
Why read if you can skim: towards enabling faster screen reading
W4A '12: Proceedings of the International Cross-Disciplinary Conference on Web AccessibilitySkimming broadly refers to different speed-reading methods that aim to enhance the rate of reading without unduly compromising on comprehension and retention of information. Skimming of content could be particularly useful for people with vision ...
