Project Goal
Incorporate media space concepts into domestic environments
![Page 3: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/3.jpg)
Influences
Previous work in computer-mediated communication (e.g. awareness, audio-related media spaces)
Home technologies (e.g. HomeNet)

Early Prototypes
CommuteBoard NeighborNet KitchenNet
Poor video performance over ISDN
![Page 5: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/5.jpg)
CommuteBoard
Handwriting and audio sensing Helping carpool participants arrange their
rides more effectively
Feedback: pros: useful, fun, casual interface.
Cons: audio not informative, handwriting hard to read, space limited
![Page 6: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/6.jpg)
CommuteBoard
Conclusions on home-based technology Use simple, expressive means to
communicate Aesthetics are important Video and audio: need high-speed to be
effective
![Page 7: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/7.jpg)
Themes
Household as displays Household as sanctuary Family life is household priority Women are household communicators Telephone not adequate
Design implications: focus on aesthetics, family life and adult women
![Page 8: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/8.jpg)
Concepts
Awareness-related In Touch- “thinking of you” tokens Presence Light – linked objects showing activity
Audio Space-related RoomLink connects rooms in 2 households via
high quality audio Note and Picture Sharing
MessageBoard- a way for collocated individuals to share notes, photos etc on the same space
![Page 9: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/9.jpg)
Feedback
RoomLink widely regarded as useful Appreciated sound quality
MessageBoard- valued for group coordination, artifact sharing abilities
In Touch – fun but not very practical Presence Light- perceived as a privacy threat
![Page 10: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/10.jpg)
Prototypes
Intentional Presence Light- share a user’s presence only when activated by user Curtain /lampshade devices Users choose icons to represent them
ScanBoard- similar to messageboard using existing technology Post messages Scan pictures move/hide notes Automatically updated through shared database
![Page 11: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/11.jpg)
Prototypes-Results
IPL valued for Intentionality and aesthetics ScanBoard valued for scanning and sharing Both valued for Expressiveness and
simplicity

Conclusions
Domestic domains are distinct from workplace environments, with different goals and priorities
Media space in homes will span a wide range Social communication is a valuable research area Let users express themselves, but keep it simple Don’t make users feel obligated to keep in touch
![Page 13: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/13.jpg)
Questions
Isn’t focus group data fundamentally flawed? Most of these applications only work if other
people you know had them also. How will that affect popularity? (curse of the videophone)
Are these applications appealing to men also?
What happens when things malfunction?

Smart Homes
Definition: Domestic environments in which we are surrounded by interconnected technologies that are responsive to our presence and actions.
![Page 16: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/16.jpg)
Aware Home Research Initiative (AHRI) Interdisciplinary work at Georgia Tech Uses both location-aware and context aware
technologies Challenges in both developing the technology
and addressing privacy concerns
![Page 17: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/17.jpg)
AwareHome
Design for people: improve communication, create memory aids, home assistants- especially good for elderly and homebound
Examples: Dude’s Magic Box
Gesture Pendant
![Page 18: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/18.jpg)
Seven Challenges
The Accidentally Smart Home Impromptu Interoperability No Systems Administrator Designing for Domestic Use Social Implications of Aware Home
Technologies Reliability Inference in the Presence of Ambiguity
![Page 19: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/19.jpg)
The Accidentally Smart Home Existing homes do not have infrastructure in place Technology will most likely be added piecemeal Result: Unintended communication btw devices How will people understand how to fix problems as
they arise? Design Challenge: Provide ways to help users
understand the capabilities of the technology and how to control it
![Page 20: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/20.jpg)
Impromptu Interoperability
The ability to interconnect without advance planning How do we solve Issues with incompatible
device/software? Challenge: every device must be programmed to
understand every device it may ever encounter or need to connect with
Standards may help devices connect with a class of devices but not every individual one
Need new models of connectivity (e.g. CoolTown, Speakeasy)
![Page 21: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/21.jpg)
No Systems Administrator
Computers in home = users become system administrators
Home networks add increased workload and complexity to admin tasks
Challenge: don’t require “expert level” knowledge to use system
How can small devices provide rich interaction without sacrificing simplicity?
How do we design for remote diagnosis and support while preventing unwanted parties from using it?
![Page 22: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/22.jpg)
Designing for Domestic Use
Vendors and users find it hard to predict in what context people will use technology
Most home devices “shared”, rules dictate use
Best technology are the most flexible Smart technology will be disruptive in
domestic environment Challenge: Designing Technology that can
adapt to domestic routines
![Page 23: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/23.jpg)
Social Implications of Aware Home Technologies Labor saving devices really labor-changing:
reduce work time initially, but increases expectations
Good parenting- discussion of “values” regarding technology use can lead to broader debates( e.g. V chip)
Privacy issues
![Page 24: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/24.jpg)
Reliability
Existing domestic technology very reliable Different development culture- wary of bugs, hard to
implement patches, upgrades Different technological approaches – bulk of functionality
placed on network, not device utility approach) Different market expectations-appliances so reliable, not
seen as complex systems Different regulations- safety, service standards in place
Challenge: Achieving expected level of reliability – need adequate time and resources
![Page 25: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/25.jpg)
Inference in the Presence of Ambiguity Technology that assists/predicts human behavior,
not well received How smart does a smart home need to be to be
useful and successful? Machine inference- greater possibility of error If inference is required, models of actions and
preferences must be built Challenge: Ensure ambiguity is not hidden from
users or parts of system that need to access it Inference needs to be predictable and recoverable
![Page 26: Casablanca: Designing Social Communication Devices for the Home](https://reader036.vdocument.in/reader036/viewer/2022062807/568150a3550346895dbea462/html5/thumbnails/26.jpg)
Conclusion
Homes not currently designed to be smart Need a balance between reliability and
Interoperability Social impact of technology hard to predict Big question: How smart does the smart
home need to be? “Smartness” makes it disruptive to users, unpredictable

Questions
How will these technologies affect the “home as sanctuary” belief?
How expensive would these systems be to set up, even if they were built in to a new house?
Will there ever be enough demand to warrant standards in connectivity?
How will Smart homes change communication within families?
Because routines are so personal and unique, how do we design a system to adapt seamlessly?
