Don Norman's jnd.org / Chapter 1: I Go to a 6th Grade Play. I went to a sixth grade play.
It was a small play, at a small school. Only the sixth grade was involved, so we were in a relatively small auditorium, with approximately 50 folding chairs crammed together on the floor. If there had been only 50 parents present, it would have been crowded. But in addition to the parents, we had the video cameras. Some parents came with camera alone, but then had to seek an electric outlet to provide power. Don Norman's jnd.org / user advocacy and human-centered design.
