Pervasive Human Centric Computing

1
Pervasive Human Centric Computing
A Dangerous Idea

• Larry Rudolph
• Laboratory for Computer Science

2
What do the words mean?

• Computers are already pervasive
• They infest every city, town, village
• Computers are already human-centric
• Are they for the birds?
• Computing
• Nobody computes anymore, well hardly anyone

3
So what do we mean?

• Pervasive
• But they are not where we need them we still go
  to them, or set them up (laptops)
• Should be like telephones, batteries, outlets
• Human Centric
• We adapt to them (but it should be opposite)
• Computation enters the human world
• Computing
• Computer-mediated functions
• Computation becomes oxygen-like utility

4
A Vision

• To bring an abundance of computation
  communication within easy reach of humans
• through natural perceptual interfaces of speech
  and vision
• so computation blends into peoples lives
• enabling them to easily do tasks they want to do
• collaborate,
• access knowledge,
• automate routine tasks

A different Vision
Hi Honey, Im home. Come see what I just bought!

The PC is where its at
8
The PC is passe?

• Exploding the PC and flinging its parts
  throughout the galaxy
• Build your computer out of components in the
  environment Just-in-time assembly
• How to use, name, control, configure, program,
  etc. What applications?

A Scenario

• I walk into Steves office and he asks me to join
  him on a trip to DC
• I slip on the anonymous fingerworn lying on his
  desk
• It recognizes my face and begins to personalize
  itself to me
• I say Call Home
• The fingerworn locates and fetches the cell-phone
  code, customizes itself into a cell phone, finds
  the number, and dials it
• I talk to my wife and verify she can take our son
  to his swim meet
• I then say Arrange a trip to DC on the 24th,
  returning three days later
• I take the fingerworn off, which promptly forgets
  everything
• I return to my office

10
Another scenario

• Birthday present A Wallet finding application
• Cameras, speech input, various output
• Configuration installation
• Extra option for two wallets
• Snoring imitates dialog
• TV selected as output device turn off TV
• Radio 2nd selection turn off radio
• Telephone, then cell phone
• Smash PC
• Application migrates to off-site server
• Application bug Car alarm goes off
• Lose sleep, lose job, no need for wallet

11
The post-PC world will be dangerous.The
question is for whom?
12
Them not us

• Transition from EDU ? COM
• Because of stable, fixed platform
• The bottom is about to drop out
• No platform (of platforms) in sight
• Transition back from COM ? EDU

13
A lack of control
14
many devices require compatible software
15
wasted power
16
The name game
17
Using each others cutting edge technology

• Speechbuilder is a great example

Overview of projects

• Virtual Fishing
• Room is the sea
• When a user joins, a boat is dropped into the
  ocean
• As the user moves, so does the boat
• User sees fish underneath the boat.
• Message in a bottle

19
Overview (cont)

• Boggle
• 16 letters in 4 by 4 grid
• Physically move to square corresponding to letter
• Shake iPaq to capture the letter
• Capture the flag
• Doom interface
• Assassin
• Shoot target when near-by
• Tilting cricket listener confuses location for
  offense defense

20
Multispace symphony

• There are four different spaces
• Each user has one instrument and iPaq
• The iPaq simulates a different instrument in each
  space
• E.g., 4 people, 4 spaces ? 16 instruments
• Global Score tells everyone where they should
  be and when they should play their note
