Technology as a separate species
From the International Herald Tribune (Nov 4, 2007) article on how GPS devices are causing problems in small English villages that can't handle the giant trucks their satnavs systems route them through:
...signs seem to be less and less effective as people increasingly rely more on GPS systems and less on maps, common sense, and their own eyes. ... 'Like if the satnav says, "drive into this muddy field," they think, "that 's weird," but they do it anyway."
If machines can be said to have a "voice," theirs is certainly condescending..." and
"...our products are getting smarter, more intelligent, and more demanding, or if you like, bossy."
Norman cautions that we and machines ".. are two different species," each with its own values, outlooks and objectives. If we recognize this, we have a better chance at communicating effectively. He also suggests we confine machine's task to those that are "augmentative" rather than "autonomous" - helping us make good decisions, not making the decisions for us.
He suggests these "design" rules
Design Rules for Human Designers of "Smart" Machines
- Provide rich, complex, and natural signals.
- Be predictable.
- Provide good conceptual models.
- Make the output understandable.
- Provide continual awareness without annoyance.
- Exploit natural mappings.
Design Rules Developed by Machines to Improve Their Interactions with People
- Keep things simple.
- Give people a conceptual model.
- Give reasons.
- Make people think they are in control.
- Continually reassure.
- Never label human behavior as "error."
The writing iis readable and thought-provoking as are all of Norman's books. A good holiday gift for the geek who reads in your house.
P.S. I was delighted that Mr. Norman himself responded to a Blue Skunk blog entry where I stated that I could not get his book in Kindle format. (His comment is about 4th from the last.) Pretty cool that he took the time to comment. It was like hearning from the Elvis of technology!
