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.
