My wife is registered blind; she can see just not very well. When we were looking for a new phone for her last year the staff in the phone shops we visited were sympathetic, but ultimately not knowledgeable enough to help.

In the end I managed to find out that vodafone has a specialist unit to help people with disabilities. I spoke to them and they recommended a number of products, but they either had limited functionality or where text to speech programmes. My wife doesn’t want a phone that talks to her, she’s self conscious as it is, the last thing she would want is each letter of her txt being spelt out to her.

The problem is with the quality of screens getting better and better and the resolution getting higher the average text size on a mobile is probably about 8px. Astonishingly most of the phones we looked at had no way for a user to adjust the text size. In my opinion adjustable text size is probably the single most useful accessibility feature manufacturers could add.

In the end we found the motorola razr had a screen that my wife could cope with so she went for that.
