The UX of Internet of Things
Tommy Sundström• UX and strategy, at Helt Enkelt
• Användbarhetsboken/The usability book
• Worked in Internet of Things projects for smart offices and heart monitoring
• Writing a book on Internet of Things
What is the Internet of Things?
Mobile phoneNetwork
Basic components of a thing
Brain Processor & Model
Muscles Actuators
Senses Sensors
Sensors• Things are aware of their environment
and/or of their internal state
Processor/Model• Sensor data is useless
• Needs to be translated
• Making sense of data is much harder than collecting it
Actuators (Ställdon)• Some things are able to change physical reality
• Many things ”borrows” the users muscles
Network• All things are connected to the Internet
• …or something equivalent (military, medical)
The things are not what they seem
A thing…
…a team• The function is often built
using a team of physically separated components
• Sensors
• Hubs
• Actuators
• User interfaces (often perceived as the ”thing”)
…the real thing• The extension of a ”traditional” IT system
• Input directly from physical reality (GPS-position of bus)
• Acts directly on physical reality (once we have self driving buses)
• Interface adapted the situation
New UX challenges• Less administrative input—systems will ”read”
physical reality themselves
• …and output—systems will act on physical reality themselves
• Essential parts of UX ”hidden” in the model(if the model is not correct, it cripples user experience)
• More information & interaction
• …in the most appropriate form, when needed, using the most efficient channel
types of things4
Dataharvester
Big Data
User
Marketing
• Targeted advertising—everywhere(Image: Personalized billboard from Coca-Cola)
• Detailed information on every aspect of the customer’s life
• Detailed information on how the product is used
• …and in what environment
Data fetichism• Lazy visionaries—Internet of Things will be like Google
• Marketing
• It is assumed that collecting a lot of data atomagically will produce knowledge
• Optimization of products, workflows and organisations
UX challenges• No one likes a spy – be invisible or at least discrete
• …or give more than you take
Data harvester• Observes – in order to big data-analyze
• Typically asynchronous – results of the analyze is not used in the situation
• Marketing (learn about the user)
• Optimization
• Monitoring & Maintanance (including many health applications)
• Typically totally dependent of the Internet
Interactor
• Engages the user
• Acts by persuading the user to act. The user is the actuator.
• Shopping. Your history and how you move in the store effects what offers are shown on in store screens—and on the web
The intelligent city• Find a
parking spot
Quantified self (Self discipline)• Training • Eating • Sleeping
Everywhere-shopping• Amazon Dash (button,
automatic, bar-code reader, voice order)
Entertainment• Interconnected toys • Virtual reality • Cyber sex
UX challenges• Engagement
• By being useful or fun
Super powers
New senses• Absolute orientation • Simultaneous translation • Remote touch • Mind controlled flight
UX challenges• Translating data into the most useful, intuitive form
• Making the interface fit the situation
Robot
Robot• Acts independently
• Home automation
• Self driving cars
• Industrial production
• Self-checkout in supermarkets
UX challenges• Finding the best way for the user to express what she
wants the machine to do
• Sometimes: Learning from user behavior
In the industry “Internet of Things” is just a new name for something that they’ve been doing for a long long time
UX
If you start with a technical perspectiveSensor →
Processor →
Actuator
”Let’s…
…build a tea kettle you can control from your phone!!”
…build a fart-meter”
Internet of Things is the new Second Life• A symbol of the future
• Attracts early adapters, for whom the technology is the value
• Early success can be a trap
• Early adapters likes to configure & are willing to invest time
• Mainstream consumers are not
How do we avoid building the
Internet of Stupid Things?
Methods
Start with user & business goalsSensor →
Processor →
Actuator
= Product
Why? For whom?
← Business/User goals
← What functionality?
← What model?
← What data?
← What sensor?
Ideal, but not innovative
Tech is often the source of ideas• You won’t get an idea like this,
if you start with user needs
• Possibility-driven design
• When technology develops rapidly,user needs can not be the creative driver
Technology
inspires
User-orientation
gives focus
Understand the user, and the environment
Environment• Is the user doing something else at the same time?
• Social context—other people can often see you when using a thing
• Shared usage—things are often used by several persons
• A swarm of things—your thing is not the only one wanting the users attention
User journeys*, experience maps
* Setup is often a frustrating part of the experience
Service design & touchpoints
• Many things are parts of a larger context or service
• Medical
• iBeacons (in-store offerings on the phone)
• Service design & touchpoint maps are methods to cover the full context
System thinking• The coffee maker in Oxford—probably the
first Internet of Things-thing
• You can see if there is any coffee, before you go to the kitchen
• But—new coffee is mostly made by someone who comes to the kitchen and discover that there is none
• Result: Empty most of the time
• We’re not designing things, we’re designing systems
Prototyping Arduino + 3D-printers makes high-fi prototypes fairly cheap
But never underestimate the power of quick prototyping
Things already sold will be the Google Analytics of IoT design• …if they call home and report usage patterns
With remote configuration they can be used for A/B testing
Return of the waterfall
Production starts
The end of agile?• Physical production often has many dependencies
(specially for consumer products)
• Christmas
• Production slots
• Features (described in documentation, retailer info, marketing material etc.)
• Continuous development hard
• Distinct product generations (the marketing logic of something new and shiny)
Agile philosophy still useful when prototyping & for products that essentially are computers
Mistakes are expensive—so easier to get a test budget• …hopefully
• Design and starting production are expensive for physical products (compared to digital)
• The cost for misstakes are higher$
DiffsHow IoT-design differs from digital
More senses• Digital: eye + ear
• IoT: + haptic + acceleration + sound + presence + brainwaves + electrodes effecting balance + …
Focus is often on something else
Symbiotic relation to the user• Thing and user cooperates
• The thing analyzes data and present them to the user in an accessible form
• The user makes the decisions
• The user is the actuator
Interfaces* of Things
* Technically, the interface is usually a set of sensors.
Men are mice
• Presence (and to some extent body language) replaces mouse/touch
• We all carry a remotely readable barcode:our phone
• Used when identity of the useris needed
• Example: The heater in your house starts working when you are on your way home
Zero interface• We will have to deal with (to) many things every day
• Solution: Zero interface. No interaction, it just works
• Sometimes the user is not even aware
• (Topp, here in Malmö, is an active proponent of this ideal)
• But, to be quiet is to be forgotten
• Will brand managers accept that their products do not attract attention? (Anti-virus do not need to, but do)
Gestures• Works well for natural and cultural gestures.
• Works well if you have only a few things.
• But, does not scaleWith many things, will you remember them?
• Will gestures be a common interface?
• My guess: No.
Voiceis likely to be a major interface for the Internet of Things
…and buttons (knobs, levers, etc.)• Oldie but a goldie
• Direct connection between control and effect
• Labeling is good for UX
• Has its limitations—almost useless for configuration and complex actions
…and apps• Configuration, complex actions and remote
control, will be handled with apps
Will the phone replace the buttons?• Phone:
• Cheaper
• Easier to set up
• Button
• Easier to understand (?), and to use
Is anthropomorphism a good idea?• Should things behave like humans?
• Should things look like humans (or animals)?
• Should things talk like humans?
Yes, it is• Humans relates strongly to things that appears to be alive
• Soldiers in Iraq did not only name their robots, they formed emotional bounds to them.There were incidents when soldiers risked their lives to save their robot.
But don’t fall into the uncanny valley

Challenges
Many physical things (like sea turtles and refrigerators) has a long life span
Computers (like dragonflies) has a short life span
Internet of Things expects them to marry and live happily together
It took Samsung Smart TVs less than a year to lose functionality
How do we make this a happy marriage?• The computer/smart phone way:
Throw away hardware after 2-4 years
• Can smart recycling make this viable?
• The set top box way: Loose coupling. Switch box every other year, keep screen
The industrial and the digital designer• The industrial (physical) designer’s culture:
• No errors
• Late changes or recalls is extremely expensive
• The digital designer’s culture:
• Time to market
• No need to be perfect, better get experience and fix it in next version.
One thing—no problem
Multiple things is a kindergarten screaming for attention
How many things are we willing to take care of?• How many things-controlling apps can we have?
TV has taught consumers to fear interconnected technology
Risk is part of the value proposition• Will this work, or will I have to spend countless hours
waiting for telephone support?
• Specially when connecting different brands
Accessibility• More senses involved
• + Environment
• = New demands on accessibility
The calendar tells your house that you have a date with Sara. Your refrigerator has checked with Saras refrigerator for allergies and preferences, and ordered the ingredients for a romantic dinner. Your car informs the house that you will arrive in 30 minutes, and the oven…

happen
Downton Abbey of ThingsSorry, but there will be no butleranticipating your every need
(There will however be a chauffeur)
Integrity
IoT designer ethics• Users are—sometimes—extremely concerned about
integrity
• When is it ok to spy on the user?
• Internet of Things will observe our lives in greater detail then Stasi ever did. Do we always have to know this much about our users?
• Is a blockchain (Bitcoin) model a feasible way to build Internet of Things?
A turnkey police state
