Your home is the one significant thing in your life that you canʼt stay in contact with online. Itʼs a big dumb box of mostly dumb things that canʼt talk to you, or each other.
Thursday, 27 September 2012 Sensors and controllers around the home, embedded computing in everyday objects, and connecting it all up to the internet so you can access and control it via web and phone. Currently that allows you to do things like...
back as 1975... This is X10 Powerhouse for the Commodore 64, from 1986. Thursday, 27 September 2012 It let you schedule lights and appliances to turn on and off, control a burglar alarm and thermostat, and could be operated remotely by telephone. Those are pretty much the things Iʼm working on right now. Except the telephoneʼs got a bit smaller and now we have the internet. Well, yeah, actually.
standards meant poor interoperability •Usability was poor ...and/or a geek Thursday, 27 September 2012 For most people, the benefits just didnʼt outweigh the cost
good at designing it in ways that work in home environment. This is where UX comes in. With my colleagues, I have been working on understanding what this technology could do for people, where it often goes wrong for people, and defining what I think a good connected home UX might look like. These come from reviewing competitors, academic research, and our own concept testing...
are in or out •One phone/keyfob = one user •Program home for optimal efficiency! Thursday, 27 September 2012 This is the (very old) AlertMe home monitoring homepage.
Thursday, 27 September 2012 The Microsoft HomeOS team take the view that this is right. People understand computers, with users, access permissions and suchlike, and that that makes this a suitable metaphor for a smarthome. This causes them to say things like “Users could manage their deployment.” Iʼm sure theyʼre very smart but this is boring corporate IT speak and most of us donʼt want to take that home with us.
a bit disorganised and bad at predicting their future needs •Life is full of contradictions and exceptions •Devices are shared, and lent •Whoʼs allowed to do what is negotiated and flexible, not completely codified Thursday, 27 September 2012 e.g. Little Jack isnʼt normally allowed to watch that much TV, but today heʼs ill so youʼre feeling sorry for him e.g. The sheets ought to be washed but everyoneʼs busy so theyʼll do for a bit longer.
Itʼs the home This one happens to be my home. I donʼt want to log into it, become a super user, or worry that itʼs going to crash or need debugging. sudo open-window Thursday, 27 September 2012
the world I want to feel out of control. And weʼve all seen how people often feel out of control of computers when they are too hard to use or do things we donʼt understand. Thursday, 27 September 2012
it •Itʼs often possible to work out who is in, out, turning the heating up all the time, or on the Playstation •When parties have different ideas about how things should be, that surfaces tensions 21 °C 19 °C Thursday, 27 September 2012 Itʼs a healthy and necessary part of most relationships to have the right to some private space, and to ignore or pretend not to notice some of the other personʼs behaviours. Technology makes this harder.
Was anyone with them?!!) How long did the cleaner really stay? If this information is up on the internet, who might get access to it? Presence surfaces trust and privacy issues Thursday, 27 September 2012
homes. They want more control of their lives” Scott Davidoff, Min Kyung Lee, Charles Yiu, John Zimmerman, Anind K. Dey: Principles of Smart Home Control (Ubicomp 2006) Thursday, 27 September 2012
actually pretty unremarkable and mundane •We develop routines to help us stay on top of the boring stuff without too much conscious effort •This allows us to save our attention for important or interesting things Thursday, 27 September 2012
most urgent and important thing in my life Thursday, 27 September 2012 It beeps when itʼs finished a load. That is fine. But it doesnʼt stop beeping until you empty it. It expects you to drop everything and come running, right now, because the washing must come out IMMEDIATELY. This is appropriate behaviour from a burglar alarm, but not a washing machine.
might leave you Thursday, 27 September 2012 Ericsson made a video about the social web of things, in which a manʼs home and his appliances all talk to each other (and him) via some weird kind of Facebook analog. It is meant to look easy but he seems to spend a lot of his time in idle chat with his house. Right at the end, his girlfriend dumps him and he spends the rest of his evening alone with the house. Apparently this is a promotional video.
messaging, lights... Sensor data is highly visible Primary aim is peace of mind ...may not map well Thursday, 27 September 2012 Monitoring has some of the properties of a burglar alarm, but not all. But it does a lot of extra stuff too. Thinking of it as a burglar alarm doesnʼt help you understand it.
broken ones At a glance, show: what it does, when, which devices are involved, and who will be affected Be forgiving: mitigate the impact of ʻincorrectʼ usage Thursday, 27 September 2012
Interusability: usability for services composed of interconnected devices. Important to create the experience of interacting with the service, not just a device. See Minna Wäljas et al paper in the references. A number of aspects of interusability, like assigning the right interactions to the right devices and figuring out what degree of consistency is appropriate across the different devices and platforms.
2012 Perhaps the biggest challenge is continuity. If i interact with the service on one device, all other devices reflect that change in state. e.g. if I turn the target heating temperature up on my physical thermostat, the new temperature should be immediately reflected on the smartphone too otherwise thereʼll be a confusing period when I have two devices saying different things. Not that easy to implement!
it I dream of time for ethno but right now, the focus is too broad, context too complex to manage it in the time I have Make wireframes and test in a lab... playing fast and loose with ecological validity No early adopters... they’re too unrepresentative Thursday, 27 September 2012
useful for testing conceptual models of new things: you can put lots of things in front of people at once and see how they interpret them Once a product's conceptual model is well defined, we focus most heavily on mobile, as the central control platform We zoom back out to web later Thursday, 27 September 2012
security lighting ? ? ? ? appliances ? Thursday, 27 September 2012 What the connected home needs is a platform: a framework for making all this stuff work together, and lots of new, unanticipated stuff too. User-centred design tools can be a bit too linear for this. For example, it’s impossible to define personas with any degree of specificity for general smart home, it's like defining personas for people who live in homes. You need different ones for different product lines, e.g. to reflect different motivations around energy (who's to say that the DIY fiend in home security is also the energy saver in heating? You have to look at fundamental logical structure of tasks and concepts and look for common components, like timers, danger warnings. You then apply UCD to explore each example. I don’t claim we’ve got this right yet and would love to find the right methods.
of things for people who live in homes! Thursday, 27 September 2012 A complex and worthy challenge, and one many more of us will be getting involved in.
