I am an iOS developer with an idea for several apps targeted toward low-vision/blind users. However, I need to get some marketing research to back-up the viability of these apps for the powers that be. Does anyone know of marketing research that has been performed about the adoption rate of iOS devices by the LV community? I have anecdotal evidence, but would need market-wide numbers to sell the concepts.
Also, would anyone here be interested in participating in focus group/beta testing of apps specifically for LV/Blind users?
