In this talk, Joe will take you on a journey to find the holy grail we are all looking for: the “perfect” design. We’ll look at a practical strategy that uses psychology to produce the ideal design for those tricky user experience design problems we face everyday.
What exactly is the perfect design? Well, that’s what you will find out in the session. We’ll look at the three aspects that define the perfect design and how you can make it work in your projects.

Psychology and the
perfect design
2. Hello, I’m @mrjoe
but you can call me
Joe.
I’ve been doing UX for 10 years
I work for cxpartners a UX agency and I work with people like Disney, Marriott
& theTrainline.
I studied Neuroscience, which was really hard.MSc Human Communication
and computing, more on that later.
5. I want to talk about the perfect
design.
Here is what you get if you type
perfect design into Google image
search.
Not what I’d call the perfect design
‘perfect design’

Today I’m going to talk to you about
the brain.
Specifically three parts of it and how
if we talk to each we can create the
perfect design.
7. anybody recognise this city? I want to
tell you a story about Buenos Aires. I
have been twice.
9. The second time it happened. I also
took a photo. What I didn’t realise
until I was putting this talk together.
It’s same damn ATM!
I thought, how can I use psychology
to understand why this happened
and to stop it happening again.

Compared to a UK one, see the problem. The Goal State is reached before
the end of the process. Therefore my brain tells me that we have reached
the end, I can leave now, and I do but without my card.

Mental Models
of how the world
works and apply them
to new situations

ATMS work differently across the world. But notice the commonality. The
Goal State is at the end of the process. Meaning bad errors are avoided, it
does make the the process different and we can’t use the ATM on autopilot
17. Cruising.
So how does this relate to digital design I hear you ask. We don’t design
ATMs.
18. I worked for Saga holiday, vacations for the over 60s. In this case ocean
cruising.
19. This was the online flow SAGA had before we started.
20. We did some research and watched how these people would book a cruise
holiday. (and yes that is a wig, but not the actual people we spoke to)
21. We spent a few days listening to calls and customer service issues.
22. We spent time trying understand the order of steps, and information
needed at each each step to reach the Goal State
23. Remember that line at the top, how the website worked. Well after the
research we talked to SAGA about how it did work, and…
24. This was how people were using the current website. Jumping backwards
and forwards, and almost always having to pick up the phone to ask a
question, the result, very few online bookings. Web analytics might spot
this..
25. The next bit was the easy bit. We took what we new and showed each step
and the information required to move to the next step. Easy if you have
done the research, if you have the data. Web analytics will never give you
this.

Thinking
(cognition)
This is the part of the brain we use when we think.
The Cerebral cortex. Used for thinking, learning, processing

31. This paper, from 2000. ATM experiment.
The same interaction, two scenarios. One plain green text on black screen.
One with a layer of design. The designed version was perceived as being
easier to use.

Emotion
This is the amygdala part of the Limbic System, it controls Emotion
It has deeper more profound effect on us. It’s connections and hormones
permeate throughout the brain, having an effect on everything we are
doing.
Emotion effects everything we do, both positive and negative.

Instinct:
The Hypothalamus &
Brain stem.
They control: Breathing,
eating, sleeping, heart

Instinct, we are
unaware of it
40. Let me tell you a story,
recognise this movie?
I was good at
computers, kids at
school, the Johnson
Gang, asked me to help
them hack ATMs.
Needless to say, I was
useless at it.

Here’s the thing. Designing for the
instinctual part of the brain is almost
impossible. Adding pictures of faces,
genitals or anything to try to nudge or
persuade is not going to get you very
far.
49. Do steps one and two and you’ll have a great design. As for persuasive
design, nudging, gamification and other trickery, let me call bullshit on
that. If you have to use those theories to sell an average product. You’ll be
better improving the product that trying to trick.
You might get tiny incremental improvements but it won’t get you a perfect
design.
The perfect design
1. Match the mental model.
2. Evoke emotion.
3. Ummm...
