Abstract
This paper presents user requirements for camera-based mobile applications in touch screen devices for blind people. We conducted a usability testing for a color reading application on Android OS. In the testing, participants were asked to evaluate three different types of interfaces of the application in order to identify user requirements and preferences. The results of the usability testing presented that (1) users preferred short depth of menu hierarchy, (2) users needed both manual and automatic camera shooting modes although they preferred manual to automatic mode, (3) the initial audio help was more useful for users than in–time help, (4) users wanted the OS supported screen reader function to be turned off during the color reading, and (5) users required tactile feedback to identify touch screen boundary.
