class logistics

  • be sure to login to blackboard over the weekend!
  • remember: post summary and questions to forum
  • summary and questions are due for the rest of semester
  • keep the summary short, no more than 4 sentences
  • post your introduction and preferred discussions for leading

during class to the forum on blackboard

  • due next time!

  • technology is immediately

recognizable, mundane

  • emulate: writing
  • glanceable
  • needs no explanation
  • easy to ignore or focus on

“The state of the art is perhaps analogous to the period when scribes had to know as much about making ink or baking clay as they did about writing” is this true today?

  • criticism: too much focus
  • n the box
  • suggest: shift focus to the

task, not the tool

shift focus to the task

criticism: multimedia

criticism: virtual reality

  • used to get our attention, rather than be in periphery

criticism?

CSE5390 & 7390 Special Topics in Ubiquitous Computing

  • used to get our attention, rather than be in periphery
  • draws you out of everyday life...
  • is this any better?

  • metaphor: the electric motor in a car
  • simpler, easier installation
  • cheaper than system of pulleys

weiser’s key issues for phase 1

CSE5390 & 7390 Special Topics in Ubiquitous Computing

15

  • a computer should know:
  • location
  • if a system knew where you were, always
  • scale
  • tabs
  • pads
  • boards

what happened to sal?

  • wakes, automated coffee
  • neighbor trail
  • kids awake notified
  • pen used in newspaper
  • foreview mirror for traffic
  • automated login and windows for other places
  • “shared” office with Joe
  • collaborative workspace with Joe

ease of the day? privacy? computer addiction? ability to communicate? choice and diversity?

weiser’s message

CSE5390 & 7390 Special Topics in Ubiquitous Computing

29

  • ubicomp is not about creating something new, but making the

unremarkable faster, easier, and more enjoyable

  • fit the computing to the problem, don’t fit the problem into a

tool

  • make computing calm...

why calm: the eras of computing

CSE5390 & 7390 Special Topics in Ubiquitous Computing

33

  • mainframes
  • personal computers
  • internet
  • mobile computing
  • ubicomp

if it isn’t calm, we will be utterly unfocused and inherently distracted

weiser: “If computers are everywhere they better stay out of the way”

slide-34
SLIDE 34

elements of “calm”

CSE5390 & 7390 Special Topics in Ubiquitous Computing

34

  • center versus peripheral attention
  • calm computing can stream naturally between them
  • periphery informs without overwhelming

weiser’s (best?) calm example

CSE5390 & 7390 Special Topics in Ubiquitous Computing

  • look out for information
  • other’s can look in
  • private enough to control

CSE5390 & 7390 Special Topics in Ubiquitous Computing

  • when would technology be cheap enough to be disposable?

is that even a good idea?

  • does it need to be disposable or commonplace?
  • power?
  • can the system be wrong?
  • is the present computing era calm?
  • is ubicomp necessarily clam?
  • what is missing from the calm model?
  • is anything private?

for next class...

  • do the summary and questions for discussion next week
  • author spotlight: Gregory Abowd
  • I am in CA for the rest of the week
  • no class on Monday (labor day)
  • next week: A0 due!
