Design considerations for Touch UI

Punchcut, a User Experience design company from San Francisco, has just launched a very illustrative video to make people know their thinkings about what´s the best approach to User Interface design:
1/ Design for immediate access
2/ Keep gestures smart and simple
3/ Leverage clear mental models
4/ Design for real hand sizes
5/ Touch feedback is key

So, here you are (Vimeo, 1:17min):

“Touch is merely on dimension that brings a human side to technology”.

These days,, the company I own, is working on an interesting project defining mobile User Interfaces wireframes. Inspiration coming from this kind of documents is always welcome. Thank you guys!
