  • 1. The Home of the FuturePerspectives on “Smart Home” from the viewpoint of HCI
  • 2. ContentsSmart Home State-of-the-Art *What is the Wise Home?Smart Home Research AreasContributions to these Research AreasConclusions / Outlook* The focus of research is COTS (consumer off the shelf) systemsavailable on the mass market.
  • 3. A state-of-the-art Smart Home
  • 4. What about the future?What could the smart home of the future look like?Increased AutomationMultimodal Interaction“Smartness” (e.g. Smart TV, UPnP, DLNA)
  • 5. “Actually, I do have a vision for the nation, and our goal is a simpleone: By the time I leave office, I want every single American to be ableto set the clock on his VCR.” G.W. Bush (US President), 1990…he failed. D. Norman (HCI Guru), 2010
  • 6. Challenges for future HomesHardware Installation, Network Configuration, NAT-Routing, PortForward, Firewall Setting, Remote Maintenance, Web Interface,Device Pairing, Scenario Programming, Parameterization, Finetuning,3G Access, …
  • 7. But why should we care about Smart Homes ?Demographic ChangeIncrease of Self ServiceUbiquitous Computing, Embedded Devices
  • 8. What constitutes a Wise Home?different possibilities.A Wise home is to its users like a mother to her child. She is supporting whennecessary, but lets the child learn from own experiences, mistakes andsuccesses. However, when the child is in danger or not able to solve theproblem on its own, she intervenes.State-of-the-Art smart Homes don’t work that way.They have to be pre-programmed in a strict and un-flexible way.They are not adaptive to changing needs.They are overruling their users.They do not learn from experiences.The Wise home will be different…

  • 11. Ageing / Well-beingChallenges of demographic change are intensivelyresearched in AAL (Ambient Assisted Living) (Steg et al.)80% of topography of EU 27 constitutes rural area25% of population are living there (Eurostat) Research on this specific context isunderrepresented Achieved Results can be appliedto other environmentsThe region I grew up
  • 12. ComfortWe spend around 70% of our time in our homes The goal is to make it as comfortable as possibleGeneral tendency to self-service (including “programming” tasks)At the end of 2012 about 90 million people were doing some sort ofprogramming (About one third of them are professional programmers).End user programming is already an essential part of our daily lives.(Holloway et al.)But people do not want to control devices, they want to have bettercontrol of their lives. (Davidoff et al.) Interfaces have to focus on Usability and User Experience
  • 13. Safety / SecurityCorrelated to the amount of time spent at home, safety and securityaspects are of relative importance“…falls among the elderly, is increasing at a faster rate than demographictrends”“…incidence … is rising in the area of home and leisure“(European Injuries Report, 2009, 2010)Product and non-product related causes of fatal home injuriesComprehensive View on injuries in EU 27 by domain(unintentional injuries)

Contribution to Comfort / ControlTwo-step study was performed addressing the following questions:- Are so-called “home scenarios” relevant?- If yes, how can they be supported by a computerized system?Leitner et al.: Scenario Programming 2013, Proceeedings of Southchi 2013.Leitner et al.: AAL 4 ALL – a matter of User Experience, Proceedings of ICOST 2010.Leitner et al.: Usability - Key Factor of Future Smart Home Systems, Proceedings of HOIT 2007.Card Sorting Pretest (OUR) Digital Prototype

  • 25. Contributions Summarydifferent possibilities.The focus of this presentation was to show how a Human ComputerInteraction perspective can enhance the development of Smart Homes.An interdisciplinary approach based on interoperable technologies enablesethnographic research to achieve results with a high ecological validity.A basic platform has been established and, in contrast to similar researchprojects, is up and running under real world conditions for almost two years.Unobtrusive ethnographic observation methods enable the collection ofmeaningful data building the basis of further research activities.A combination of methods allows for the identification of psychological,sociological and social aspects influencing the access to technology ingeneral and smart home technology in particular. For example, significantgender differences could be observed within Casa Vecchia.
  • 26. What constitutes the home of the future?different possibilities.Smart Homes are not adaptive or flexible:The WISE home adapts to the needs of its inhabitants, by enabling, e.g:- Multimodal interaction- Spontaneous interruption of automated procedures(such as cruise control in a car)- Interoperability of devices from different manufactures- Learning of patterns of daily activities- Consideration of changing life circumstances and stages of life So that we come closer to the goal that interaction with and within thehome is “as refreshing, as a walk in the woods”. (Weiser, 1991)
