Nespreso Zenius with cellular connectivity
Nespresso is a coffee service that happens to make devices.

1. Find device 2.Tap home button 3.Slide to unlock 4.Enter PIN 5.Find app 6.Tell it what product 7.Tap ‘Add to basket’
Connected product model
1. Pick up device 2.Tell it what product

Device ecosystem plays
This is a way to make this better.
But it needs to stand on its own as well.
20
Device ecosystem plays
The battery as delivery mechanism

Design for IoT
What’s design for IoT all about?
22
Design for IoT has many facets
It’s no longer just UX and industrial design.
23
Designing Connected Products
What’s different about UX for IoT?
Technology of connectivity
Product & service definition & strategy
Design methods for connected products
Industrial design & Interface types
Prototyping
Cross-device interactions
Responsible IoT design
Designing with data
Value proposition
Conceptual model
Interaction model
24
From value prop to interaction model
What does it do? How does it work? How do I use it?
Images: Instructables, How It Works Daily
25
Productisation
What does it do?
Why would I want it?
26
A products solves a specific problem.
Nest don’t talk about connectivity, just about how it is a better smoke alarm.
27
A tool puts the onus on the user
A connected socket requires the user to solve their own problem.
28
A niche example from Belkin Wemo
This is a product.
- Clear benefit - Focussed context
29
Mass market consumers want products, not tools.
Product Tool
30
Design methods
Design can help develop and focus the value proposition early on.

Press release Sketch-the-box / sketch an advert
• Can this service, idea or product be plausibly conveyed?
• Are we able to convey the idea in simple terms?
• Forces you to clearly and simply convey the value and why anyone should care.
• Can be iterated quickly.
• Why should people care? • How do you persuade them? • How can you proof your
claims?
32
Conceptual model
How does it work?
33
Non-connected products are conceptually quite simple.
34
Connected products are more complex.
35
Connected products are more complex.
Connectedness means users have to think about system models.
36
Extra stuff to think about
Connects via your WiFi No hub
Connects via ZigBee Comes with a hub
Connects via ZigBee Requires a hub, but
doesn’t come with one
37
Explaining the system model
Images: Lowes, Apple
You might need to explain your system model.
38
Explaining the system model
Or develop a really good way to simplify it.

Interaction model
How do I use it?

Interusability
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: http://bugi.oulu.fi/~ksegerst/publications/p219-waljas.pdf

A tale of two thermostats…

Hardware Simpler & cheaper to design & make. More expensive due to UI.
Iteration & updates
Quick and easy to iterate the product,app stores, developer community.
Can be tricky. Firmware updates, physical controls.
User identity Smartphone can act as proxy for user identification - analytics.
Everyone can use the thermostat, but less easy to learn about users.
Smartphone Requires charged & connected smartphone.
Works independent from smartphone.

Interusability
Composition
Consistency
Continuity
45
Consistency is a two-way street.
One one hand: Platform conventions
On the other:Consistency within your touch points
Android: Contextual menu
iOS: Separate screen
46
Top priority: terminology
However different the UIs, identical functions or settings must have the same name.
Consistent use of terminology
47
Consistency
Secondary colour
Typeface, terminology, accent colour Accent colour
CMF
Paper insert as a means to delay decision making.
This is hard across physical/digital development timelines.

Consistency is a two-way street.
Platform conventions vs. System consistency

Continuity
Coherent flow of interactions and data across devices.
51
Hard because:
1. Latency and reliability of the network.
2. Battery powered devices that only connect intermittently.
52
Has my action been executed?
Delays & interruptions mean there is a third state between on and off.
53
Option 1
A little white lie to make it feel smooth. Showing the action as executed before it really has.
54
Option 2
Transparency at the expense of a more complex UI flow. Communicating what is actually happening.

In progress
Off

UIs might need timestamped data because they may be out-of-sync.
57
A word of caution
58
Error proof power tools
59
“Guided cooking for guaranteed success”
60
Reducing “time to destination”
61
Smart vending machine
62
Design responsibility
Connected products will reach far deeper into our everyday lives than anything before.
We should be careful what values drive them.
63
Design for IoT has many facets
These were just a few of the areas your design needs to address…
