A few years ago I taught a class at New York University in the Interactive Telecommunications Program, called, “1, 2, 10.”
The class explored the then-nascent challenge of designing apps and experience across the multiple screens that popped up everywhere in our lives. The numbers 1, 2, 10 defined the distance between a screen and a person’s face: The cellphone being approximately one foot away, the desktop computer and tablet about two feet away, and the television about 10 feet away.
