Notes from a small field posted a neat idea for iPhone accessibility a couple of years back. He proposes an accessibility mode, where the iPhone (or any touch screen device) engages a very simple interface for the disabled. A while ago, I posted about a similar concept for the desktop computer, but that has not achieved any traction either.
The basic idea is for a touch screen device, like the iPhone, to support an accessible mode where, instead of the usual graphical buttons and layouts, large areas of the screen are used with a telephone prompt style system to interact with the user. For example, an audio prompt to, “Press the top right of the screen to make a call” and so on. High contrast blocks of colours would make it possible to find the right area with very little vision, and completely blind users could find the edge of the screen by touch, with small modifications to the case if necessary. Numeric input, to enter a phone number for example, could be handled with simple tactile markers arranged around the outside of the screen. Switching to the accessible mode could be as simple as pressing anywhere on the screen for a few seconds, or recognising a pre-paired bluetooth headset. The main advantage of all this is that it is largely software based with no additional external controls required, so ideal for small devices, or touch screen kiosks that have already been installed… and easy to add to something like the iPhone.
Instead of Apple implementing this, it could be done with an app. Pieces of it probably have already been done.. There are numerous voice dialer apps for the iPhone. Possibly one of these offers a super simple, easy-to-see interface.
