Luke Wroblewski tweeted 3 links about Designing for the thumb:
1. Designing for Thumb Flow features video that shows how you use polar with one thumb.
2. Scott Hurff explains how the “thumb hook” gesture used often in Facebook’s new Paper app might drive the sale of arthritis medication in a few years. He then shares a Thumb Zone template to use when designing for the most comfortable area for one handed touch.
3. Michael Oh demonstrated the Vice Versa UI pattern that bisects the screen diagonally and allows for a more natural thumb motion. This works best for two choices that are the opposite of each other.
