But despite this we still forget the user. Fingers and thumbs take up space, and cover the screen. Corners of screens have different accuracy than the center. It's time to re-evaluate what we think we know. Steven reviews his ongoing research into how people actually interact with mobile devices, presents some new ideas on how we can design to avoid errors and take advantage of this new knowledge, and leaves you with 10 (relatively) simple steps to improve your touchscreen designs tomorrow.
