Web Directions Unplugged 2011, Seattle, May 12th 10:45am.
The average size of an adult human’s finger pad is 10-14mm. The average size of a cursor or stylus tip is 1-2mm. That fact alone means that designing native touchscreen apps is an entirely different thing than designing web, desktop, or even traditional mobile apps. This talk outlines the most important concepts, guidelines, and practices to keep in mind when designing with fingers and hands in mind. We’ll cover interaction zones (where it’s easiest for fingers to reach), touch targets (size and distance apart), kinesiology (how fingers can bend, move, and stretch), and signaling (how users can become aware of gestures).
