UX for the internet of things: ThingsCon 150505

  1. 1. What’s different about UX for the internet of things? ThingsCon 2015 Claire Rowland - @clurr Image: Disney Movie Year
  2. 2. Hello :) - Independent UX and product consultant - Lead author: “Designing Connected Products: UX design for the consumer internet of things” (due May 2015)
  3. 3. My grandfather could probably have told you how many electric motors he owned. There was one in the car, one in the fridge, one in his drill and so on. My father, when I was a child, might have struggled to list all the motors he owned (how many, exactly, are in a car?) but could have told you how many devices were in the house that had a chip in. Today, I have no idea how many devices I own with a chip, but I could tell you how many have a network connection. And I doubt my children will know that, in their turn. Benedict Evans
  4. 4. Visions of IoT often look like this
  5. 5. …but the reality can be more like this ‘It’s a bit glitchy but it’s OK, you just have to be in the room at the same time’. Actual review of a connected home system
  6. 6. It’s not just UI and industrial design
  7. 7. Facets of IoT UX
  8. 8. Image: Nissim Farim We don’t (yet) expect Things to behave like the Internet The average consumer is going to find it very strange when objects take time to respond, or lose instructions.
  9. 9. 3 part diagram: Value proposition Conceptual model Interaction model What does it do? How does it work? How do I use it? Image: Instructables Image: How It Works Daily
  10. 10. Value propositions: Solve a tangible problem
  11. 11. Mass market products should - Solve a real problem people have (value) - Offer a good solution (desirable, usable) - Come at a cost (financial, effort) that feels in proportion to the value
  12. 12. Product Tool In areas where they don’t have expert knowledge or are short on time consumers need products, not tools
  13. 13. Nest do productisation really well
  14. 14. Belkin’s mobile app is good, but a connected socket is a tool that requires users to solve their own problems
  15. 15. This is a product
  16. 16. Conceptual model: Connected products are more complex to understand
  17. 17. Conceptual models used to be simple
  18. 18. Connectedness requires users to think about system models Which bit does what? Where does code run? What fails/still works if connectivity is lost?
  19. 19. You can explain the system model... BERG Cloud bridge: transparent network comms
  20. 20. Or you can make the conceptual model simpler Users will get more familiar with connected products… but not for a while
  21. 21. Using it: Interusability: coherent UX across the system Cross-Platform Service User Experience: A Field Study and an Initial Framework. Minna Wäljas, Katarina Segerståhl, Kaisa Väänänen-Vainio-Mattila, Harri Oinas-Kukkonen MobileHCI'10
  22. 22. Functionality should be distributed to suit the context of use AKA composition
  23. 23. Consistency Create device-appropriate interfaces that feel like a family
  24. 24. Continuity Dealing with latency, reliability and intermittent connections BERG Cloudwash prototype
  25. 25. service UX …has my action been executed or is it still in progress? Has it worked? Why/why not? How will I know if it fails?
  26. 26. …the right solution depends on context
  27. 27. …intermittency can also cause discontinuities devices that are out of sync can give different status information 19 2 min delay 21
  28. 28. Designing for interconnected devices: Handling complexity
  29. 29. A simple platform for a few devices is one thing...
  30. 30. • but this is a world of single apps, single devices, single hub But we want things to work together video by Ericsson Ericsson
  31. 31. Technical interoperability is a huge issue
  32. 32. But getting things to work together in common sense ways is also crucial Add to: lighting controls? security system? both?
  33. 33. alarm video lighting heating temp.schedule security Relationships quickly get complicated…
  34. 34. …and then some alarm videotemp.schedule schedule security controls lighting baby appliancessafety energy smoke medicine controls heating
  35. 35. notificationsservices controls devices presence contacts user needs The UX platform challenge: creating the logic that drives sensible interrelationships
  36. 36. A final thought Good consumer UX for IoT is surprisingly hard
  37. 37. Tesler’s law of the conservation of complexity: As you make the user interaction simpler you make things more complicated for the designer or engineer Larry Tesler, former VP of Apple
  38. 38. Thank you @clurr
