WHAT IS UX?
During a typical day, the
brain accounts for about
20% of our daily energy
our energy is depleting,
the natural reaction is to
seek some rest.
LIKE A SIEVE
It’s like decoding
gathered data that we
forget with the passing
Within a month since
experiencing a set of
repetition, we lose 80%
of what we’ve learnt.

them touches a different
part of it and is sure

A FEW TRUTHS ABOUT THE USERS
In his book “The Power of
Habit”, he describes our life
as something consisting of
thousands of automated
habits that simplify our
Technology is a part of this
The starting point of
designing a mobile app
should be to understand the
future users’ need that we
want to satisfy.
INTERACTION WITH A DIGITAL PRODUCT
1. It’s just a picture, so we can only review the visual layer and the
placement of the elements (usability)
3. We also don’t know whether the users stumble upon any problems on
2. We don’t know who uses this page and what their expectations are
Snapchat - First-time experience
Test participants aged above 40 were frustrated with the lack of
instructions for beginner users
Test participants aged below 25 were self-confident and wanted to
discover the hidden features of the app and the meaning behind the icons
Snapchat - Additional features
The members of the youngest group were interested in the additional
features (Stories / Discover) and devoted the most time to them
The members of the oldest group were disoriented and couldn’t focus on
the entertainment. They were still trying to figure out the main function of
„“I’m really not sure about this whole
Discover thing. It seems to bug me a bit.
I’m not sure what it’s about.”
- Male test participant, 37, United States
Snapchat - Overall appeal
In both groups, there were people who weren’t convinced to using the app
and to the app itself in general
Many members of the youngest group said they did not see any particular
advantage of the app over the other ones, but they still felt like “someone
had designed it for them”
The members of the oldest group indicated “a generation gap”
Younger users, who stuck to the app, had fun using it.
Their tolerance “for fun” was much higher than in the oldest group, whose
members focused on possibilities and functions.
