So when designing, be careful of using color as a cue – remember that there are those who may miss it. Boldness, contrast, and pattern differentiation can go a long way toward preventing problems. Also, always, always look at programs on a variety of other monitors and devices – the variations in color display might surprise you.

Some resources on color blindness and testing:

• Color Vision Testing
• Graybit Testing
• Color Blindness Simulator

iPhone was already pretty good at helping out if you’re blind or deaf. But until iOS 5 came along, it was tough rocks if you had motor-control problems…

When you tap it, you get a floating on-screen palette. Its buttons trigger motions and gestures on the iPhone screen without requiring hand or multiple-finger movement. All you have to be able to do is tap with a single finger — even a stylus you’re holding in your teeth or fist…

I doubt that people with severe motor control challenges represent a financially significant number of the iPhone’s millions of customers. But somebody at Apple took them seriously enough to write a complete, elegant and thoughtful feature that takes down most of the barriers to using an app phone…

This is really great to see. Keep it up, Apple. Keep caring.

I’ll have much more posted to the resource section in the next week.
