There is a significant need for access to low-cost assistive mobile services through standard devices. Many special purpose devices that provide services are specialized for few functions, are usually not networked, and are expensive and difficult to sustain. Mobile devices and their sensors, along with audio or tactile output, show immense promise for improved daily accessibility to the world for blind people on the go. Particularly, the camera has the potential to expand environmental knowledge using context and computer vision. This research will investigate general camera interaction techniques, mobile device and camera accessibility for blind users, and computer vision techniques for recognition given mobile phone limitations. These studies along with formative studies and focus groups with users will inform the design, implementation, and evaluation of future lab and field studies for semi-autonomous focalization with the camera for blind users.
