“DESIGN: is a funny word. Some people think design means how it looks. But
of course, if you dig deeper, it’s really how it works. The design of the Mac
wasn’t what it looked like, although that was part of it. Primarily, it was how it
worked. To design something really well, you have to get it. You have to really
grok what it’s all about. It takes a passionate commitment to really thoroughly
understand something, chew it up, not just quickly swallow it. Most people
don’t take the time to do that. – Steve Jobs

“DESIGN: This is what customers pay us for–to sweat all these details so it’s
easy and pleasant for them to use our computers. We’re supposed to be
really good at this. That doesn’t mean we don’t listen to customers, but it’s
hard for them to tell you what they want when they’ve never seen anything
remotely like it. Take desktop video editing. I never got one request from
someone who wanted to edit movies on his computer. Yet now that people
see it, they say, ‘Oh my God, that’s great!’” [Fortune, January 24 2000 – Steve
Jobs

Introduction to Human Computer Interaction
What is Human Computer Interaction?
Some Webster Definitions:
• Computer - a programmable usually electronic device that can
store, retrieve and process data
• Application - a program (as a word processor or a spreadsheet)
that performs one of the major tasks for which a computer is used
• Technology - the practical application of knowledge especially in a
particular area The terms “computers” and “technology” are virtually
synonymous
• Computers support many technologies
– Obvious computer applications
» Word, Web Sites
– Non-obvious computer applications
» Automobiles
» Mobile Devices

A word on the PC vs Mac
“I wish him the best, I really do. I just think he and Microsoft are a bit narrow. He’d be a broader guy if he had dropped acid once or gone off to an ashram when he was younger.” [Steve Jobs on Bill Gates, The New York Times, Jan. 12, 1997]
“It will go down in history as a turning point for the music industry. This is landmark stuff. I can’t overestimate it!” [On the iTunes Music Store, Fortune, May 12, 2003 – Steve Jobs
