Handouts for Next Time:
Many Wireless Articles for Prof. Poor's Lecture next time
Assignment for next time:
1) Read the papers, be ready for discussion.
2) Go out on the web and begin a page of links to
related topics/articles you're personally interested in.
What is this class?
Opening thoughts:
This class is not exactly about computers.
Nobody really wants to wear a computer.
Grandma doesn't care if there's a computer in her toaster.
Why do I have to "sync" my computers?
What's up with battery life?
Nerds and early adopters don't drive a market/technology
etc. . . .
What do people want?
People do want information, communication, help,
assistance, empowerment, . . . .
But, people also want: Privacy, security, reliability,
ease of use . . . .
What's An Information Appliance?
Today, device that helps you tap into a database.
Tomorrow, devices that connect to each other, share
and track, etc. . . .
What are the roadblocks today?
Computing power
size
energy
tethers
bandwidth
realtime?
standards
I/O
marketing (perceived need)
competition
algorithms
user interface
persistance (obviousness) of function
. . . .
What of these are we going to look at in this class?
We will talk about, but maybe can't do so much about ourselves:
size
power consumption
marketing
competition.
We will talk about:
computing power
Tethers and wires (wireless RF and Infrared)
I/O
algorithms
system architecture
Apps (marketing and ???)
Basically, if somebody sold the components,
we'd (we will) know what to do.
Some things to ponder:
What is "information"
What's an "appliance"
Does "Information Appliance" make sense given these?
What are the multi of multi-media?
Text? (Hypertext?)
Sound
Video
Touch
Any More?
What will the library of the future look like?
What will entertainment of the future look like?
What will the house of the future look like?
What will the shopping mall of the future look like?
What will the office of the future look like?
What will the hospital of the future look like?
What do we mean by future?
What does all this have to do with the web?
Internet provides (provided) a loosely coupled information system.
Is the Web passe? What's next?
Wireless web browsers are here now.
Is it worth $50.00 per month to get directions
to the nearest Thai restaurant?
What is worthwhile, or at least marketable?
In 1 year, in 10, in 50?
What we hope to do:
Take each of the things that we cover, and
discuss what does and does not work
Look at what hardware/software/tools are available
Look at which ones we have available (in the labs).
Think up a cool project
Do it
More future assignments to think about:
Go out and find all you can on the state of the
art in the devices that interest you.
Write a scenario for some of the "What wills" above.
