How Smart Homes Learn The Evolution of the Networked Home and Household Marshini Chetty, Ja-Young Sung, and Rebecca E. Grinter Ubicomp 2007 Presenter:Brian

Contribution Overview A starting point for discussing within the Ubicomp community about whom and how the home network will be designed Networked technology interacts with a house’s infrastructure.

Outline Introduction Background Participants and Methods Networking in the Evolving Home Conclusion

Introduction Computing has migrated into the home. Past research focus on individual device Home networking Under-explored Interaction with home’s infrastructures Ubiquitous computing research rely Seamless integrations?

Four themes of paradoxes Virtual boundaries Home network control Home network access Responsibilities V.S. possibilities of WiFi Introduction

Outline Introduction Background Participants and Methods Networking in the Evolving Home Conclusion

Domestic Technology &Home Networking Home networking is only the apart of domestic technologies. Smart home research solves the problems associated with infrastructure.

Outline Introduction Background Participants and Methods Networking in the Evolving Home Conclusion

11 households in Atlanta

Outline Introduction Background Participants and Methods Networking in the Evolving Home Conclusion

Site Affected what Stuff is installed and required Shaping Services and managing boundaries Cable, Digital Subscriber Line Mismatch of physical and virtual site boundaries Is it good or bad for community?

Site Network security: personal data WEP and MAC control to manage security

Structure Ethernet installation with wired LAN due to reliability of connection Embedding the home networking into the Structure Challenges: cost and complexity Wireless

Service for responsibility Internet, cable, phone line Ethernet, PowerLine and X10 Service Provider v.s. DIY Financial and technical People can not trust and accept the responsibility for the Ubicomp community. Ex.TW Cable

Space for access paradox Space Plan computer in kitchen Private space Constrained access for children Against ubiquitous access

Stuff for the control paradox Devices Computing and AV related equipments Complexity of device configuration and interoperability Multiple remotes, noticed maps and instructions Householder-centric V.S. technologically- centric

Outline Introduction Background Participants and Methods Networking in the Evolving Home Conclusion

Security is the most concerned for Site, Service, Space Stuff must be made easy use, ex. iPod Householders should have greater degree of responsibility for designing and delivering the Service of the home network.
