At Home with Ubiquitous Computing: Seven Challenges

“Smart homes” better people’s lives with increased communication, awareness, and functionality However, there exist technical, social, and pragmatic challenges Raise awareness of existing domestic technology literature Increase the use of situated studies an overview

At Home with Ubiquitous Computing: Seven Challenges

Technology is getting there:

  • Moore’s Law
  • Everything networked and wireless
  • Increased vendor focus
  • Proof of concepts exist: Aware Home @ Ga Tech

But, there still exist some challenges! the smart home is coming

At Home with Ubiquitous Computing: Seven Challenges

Current “smart” environments are intentional More realistic that technology brought piecemeal into the house Even mundane examples, demonstrate big problems How do users debug their home? Is this simply “a design problem?” Solution is to provide affordances the “accidentally” smart home

SLIDE 8

At Home with Ubiquitous Computing: Seven Challenges

When designing think of these questions:

  • What kinds of affordances do we need to make the system intelligible?
  • How can I tell my device is interacting?
  • What are the boundaries of my smart home?
  • What are the potential configurations of my devices?
  • How can users be made aware of the entire houses’ affordances?
  • Where will the locus of interaction be in a system that isn’t in one place?
  • How do I control these devices and the whole system?

At Home with Ubiquitous Computing: Seven Challenges

Learning from the telephone Learning from the cell phone Learning from domestic technology studies

  • domestic technology use governed by rules of the house
  • television use indicated who “controlled” an area of the house
  • teenagers used individually owned technology to coordinate using a shared

technology

  • teenagers used “quiet” technologies to avoid disrupting other’s routines

Are domestic technologies labor saving? Introduction of technology into the home changes societal expectations Has the introduction of technology increased or shifted the amount of work you do? TV has changed “good parenting” to controlling what not if your child watches In Europe mobile phones teaches children about managing money and safely gives them increased independence social implications of aware home technologies

At Home with Ubiquitous Computing: Seven Challenges

Current domestic technology is pretty reliable Because of differences in:

  • Development culture
  • Technological approaches
  • Expectations of the market
  • Regulations

Current machine inference is kinda bad (e.g. Clippy) How smart does a smart home have to be? Is it better to not act or to act and be wrong? interference in the presence of ambiguity

SLIDE 19

At Home with Ubiquitous Computing: Seven Challenges

Current machine inference is kinda bad (e.g. Clippy) How smart does a smart home have to be? Is it better to not act or to act and be wrong? Modes of intelligence:

  • Infer state of world through interpretation of sensor data
  • Infer existence of states by aggregating other contexts
  • Inter my intent based on its view of the state of the world
  • Preemptively act of the assumptions of my intent

Predictability is important

  • System’s expected behavior is known
  • System’s facilities for detecting or inferring this condition are known
  • Provision is made for the user to override the system’s behavior

Awareness

  • In Touch: tokens can transmit touches to other token holders
  • Presence Light: pair of linked lights use their brightness to show activity from the
  • ther’s context

Audio

  • RoomLink: two locations are linked, so you can hear everything that happens

there

Note and Picture Sharing

  • MessageBoard: people in different locations can communicate with each other

by drawing on a paper-sized whiteboard and can also use it to send physical articles (snapshots, drawings, etc)

RoomLink and MessageBoard resonated with participants Desirable attributes for social communication devices:

  • Fun to use, low cost, simple to operate
  • Keep in touch or assistance with monitoring
  • Respected privacy and didn’t create new social obligations
  • Multiple communication modes and enough information
