Transcript of UX for the internet of things: ThingsCon 150505
What’s different about UX for the internet of things?

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.

Visions of IoT often look like this

…but the reality can be more like this

It’s not just UI and industrial design
Facets of IoT UX

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.
3 part diagram:
Value proposition
Conceptual model
Interaction model
What does it do? How does it work? How do I use it?

Value propositions:
Solve a tangible problem
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
Product Tool
In areas where they don’t have expert knowledge or are short on time
consumers need products, not tools
Nest do productisation really well
Belkin’s mobile app is good, but
a connected socket is a tool that requires users to solve their own problems
This is a product
Conceptual model:
Connected products are more complex to understand
Conceptual models used to be simple
Connectedness requires users to think about system models Which bit does what? Where does code run? What fails/still works if connectivity is lost?
You can explain the system model...
BERG Cloud bridge: transparent network comms
Or you can make the conceptual model simpler
Users will get more familiar with connected products… but not for a while
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
Functionality should be distributed to suit the context of use
AKA composition
Consistency Create device-appropriate interfaces that feel like a family
Continuity Dealing with latency, reliability and intermittent connections
BERG Cloudwash prototype
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?
…the right solution depends on context
…intermittency can also cause discontinuities devices that are out of sync can give different status information

Designing for interconnected devices:
Handling complexity
A simple platform for a few devices is one thing...
• but this is a world of single apps, single devices, single hub
But we want things to work togethervideo by Ericsson

Technical interoperability is a huge issue
But getting things to work together in common sense ways is also crucial
Add to: lighting controls?
security system?
both?
alarm video
lighting heating

Relationships quickly get complicated…
…and then some

The UX platform challenge:
creating the logic that drives sensible interrelationships
A final thought
Good consumer UX for IoT is surprisingly hard
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
