1 Home Automation in the Wild: Challenges and Opportunities A.J. Brush Bongshin Lee Ratul Mahajan Sharad Agarwal Stefan Saroiu Colin Dixon

2 Microsoft Research2 Smart Homes Is it possible to create a home environment that is aware of its occupants whereabouts and activities? The Adaptive House, Mozer et al. Georgia Tech Aware Home Develop a home that essentially programs itself by observing the lifestyle and desires of the inhabitants, and learning to anticipate and accommodate their needs

3 Microsoft Research3 Don’t forget Hollywood It's up to Ben to match wits with PAT's central intelligence and "out-smart" the Smart House once and for all!

4 Microsoft Research4 Home Automation Capability to automate and control multiple disparate systems Motion sensor Door sensor Camera Programmed light switchesWall Panels Phone Access Lucero, S., Burden, K. Home Automation and Control, ABI Research 2010

5 Microsoft Research5 Adopting Home Automation Do-It-Yourself (DIY)Outsourced Our goal: Better understand current state of home automation and learn from people’s long term use.

6 Microsoft Research6 Study Method 14 households with one or more of the following:  Remote lighting control  Multi-room audio/video systems  Security cameras  Motion detectors Inventory Semi-Structured Interview Questionnaire Home Tour Outsourced DIY Chetty, M., Sung, J-Y., Grinter, R.

8 Microsoft Research8 Living with Automation Convenience “It allows me to be lazy, honestly, because every day [before automation] I would go double check the locks, make sure all the lights are off on all the floors and make sure that everything’s closed.” Technology consumer from DIY house 6, D6_C

9 Microsoft Research9 Why? Peace of Mind O: over various devices DIY: over what they installed and enabled. Control Monitoring

10 Microsoft Research10 Diversity in Installation & Desires From X10 to control a few lights to embedded panels in every room MediaSecurityEnvironmentControl

11 Microsoft Research11 Augmented, Not Smart User-controlled Rule-based

12 Not ready for broad adoption Caveat 1: Not problems for our participants Caveat 2: Not answering whether functionality is generally appealing 4 barriers Cost, Inflexibility, Manageability, Security

13 Microsoft Research13 Barrier 1: High Cost of Ownership + DIY: $200 - $60,000, $5,000 median O: $13,500 – $120,000 $40,000 median DIYs trade-off lower monetary cost for time

14 Microsoft Research14 Barrier 1: High Cost of Ownership Consultant visits not a big factor Two Surprises Low perceived value of additional applications

15 Microsoft Research15 Barrier 2: Inflexibility Structural or Retrofit? (9 put automation in place during structural changes) Surprise: Thinking ahead to moving… DIY: Use expertise to overcome Outsource: Choose one brand Integration Ease or Flexibility

16 Microsoft Research16 Barrier 3: Poor Manageability Our households were well-equipped to manage Difficult to customize for Outsourced Complex UIConsultant Required “I started explaining the panel (how to call fire department) to them and they looked in dread. People just don’t want to touch it. And my own mother sat in our house in the dark, because she was scared to touch any of the controls.”

17 Microsoft Research17 Barrier 3: Poor Manageability Iteration required “I thought when I went into this, I’d want my alarm system integrated and I’d want these automatic features firing off in the background like, you know, I’d wake up and music is playing in my bathroom and the lights come up, you know all these Jetson type things. And the challenge with that, while they’re all great, I don’t live that structured of a life, not waking up into [it] every day, and I'm not going in the shower every day at the same time. And you know, I don't want to hear music all the time. So I don’t think the routineness of automation is what I was really wanting.” (D8_G)

18 Microsoft Research18 Remote access – Eight households currently have remote access enabled – Tension between convenience and security Barrier 4: Difficulty Achieving Security Door locks Cameras Very technically savvy participants concerned about vulnerability of remote access

19 Microsoft Research19 What restrictions would you place (if any) on applications you were interested in buying? Presence based security All other restrictions: – Adult household member – Child household member – Guest – Household technology guru Simple User Groups for Future Needs

20 Microsoft Research20 Implications for Research Bandwidth Needs vs. Structural Changes

21 Microsoft Research21 Implications for Research Bandwidth Needs vs. Structural Changes Standalone Devices vs. Home Integration Individually managed sub-systems Cross-device functionality challenging Hard to incrementally add functionality

22 Microsoft Research22 Implications for Research Bandwidth Needs vs. Structural Changes Standalone Devices vs. Home Integration Individually managed sub-systems Cross-device functionality challenging Hard to incrementally add functionality Simple Confidence-building Security vs. Desired Functionality

23 Microsoft Research23 Interviewed 14 households with home automation, DIY and Outsourced 4 Barriers to broader adoption: – Cost of ownership (Time & Money) – Inflexibility – Poor Manageability – Difficulty Achieving Security Identify directions for future research – Eliminate the need for structural changes – Enable composition of home devices – Simple security that can be confidently configured Concluding Remarks
