Yet another reason to get an iPad. Check the “Rewind” gesture at 1:35.
Here are a few examples of using Touch Notation to encode various gestures. When I’m creating formal documents using Touch Notation, I tend to use black for the number of fingers and blue for the entire gestural part, just to give a subtle sense of energy and motion to the gesture. You’ll find that the gesture instructions in tutorials in the iPad versions of the iWork apps do the same thing.
- Tap (with 1 finger)
- Double-tap with 3 fingers
- Swipe right with 2 fingers
“Within the last twelve to eighteen months, I’ve crossed a threshold whereby the vast majority of my work is now aimed at touch-screen devices. I often have to sketch out feature specs, interaction designs and so forth, and I enjoy working on paper whenever I can. I quickly encountered a problem: touch-screen gestures are difficult to describe concisely. To solve this problem, I created a means of talking about such gestures symbolically; I call it Touch Notation.”
“During Apple’s 90 minute unveiling of the iPad this week, a lot of new multi-touch interactions were shown off. But they went by fast. So as a service to digital product designers everywhere, we took the time to extract 8 minutes of new user interface demos from the iPad keynote. Now you can quickly just catch the UI in action on Apple’s new native iPad and iWork applications.”
