Developing UI for Any Person, Any Device, Anywhere

Universally designed interfaces work anywhere, on any device, for any user. They’re also future-friendly, which means they’re ready for consumption on devices that haven’t even been invented yet.

The best part is that it's not even that hard; it just takes a little knowledge and a little practice. This session will cover common UI patterns developers often misuse, and how they can be modified to be considered universally designed, automatically opening up new revenue streams you didn't even know existed.
