Et si vous connaissiez les émotions de vos utilisateurs? | Pierre-Majorique Léger | TEDxMontreal


[Music]
our smartphones are they
really require are very useful
are essential to our daily
they are able to recognize
our voice most of the time but are
they can recognize our
emotions
If our phones were
truly be a leader
that is capable of detecting by
stressed example when expecting a
Texting significant but our battery
is almost flat if our shelves
were really smart it
would identify
our frustration when the function
self-correcting us say
things that really mean if
up was really demanding
would identify our
emotions take over and we
help make impulse purchases
and it was possible to know that
we humans generate
the equivalent of an encyclopedia
British emotion in everyone
other words our reactions
physiological generates the equivalent
a million pages of text then either 1
gigabyte per hour is equivalent
good documentary in HD I am
researcher I have a lab and I
access to a variety of sensors that
can record in real time
the human emotion of users
interaction with all technologies
kinds of shelves phones
computers find my passion
ways of being able to take
Account emotion by design
products and services to create
experiences that will entice people
him to use and ventilated room
used in other words what I
do in life as work is
we are trying to develop new
ways of assessing the experience
User really experience
experienced by people when they
interact with technology in
order to be able to use this
emotion possible to make our
devices may be a little more
smart before you explain
how what you can do with
this mass of data it absolutely
throne mick and that can be collected on
your emotions when you are
interaction with technology
let me explain how
today we are able to
to evaluate the user experience
to do this let me
have a professional
user experience it today
just finished designing a
new website and it will ask a
User try to
first business is
navigate and Hold
website to make an impression
and after a few minutes
professional will ask
the user what you think
is what you can evaluate on a
scale of 1 to 5
usability say
the user responds three out of five
what does it mean clearly
the experience is not optimal some
something wrong but what exactly
perhaps the user makes a
average
maybe it is the beginning and easy
at the end perhaps the user
will not tell us frankly what they
perhaps think actually think
it’s a lake is consciously
not able to retrospectively
come back and understand what
contribute to degrade his experience
in the background there is nothing like that which
allows professionals to
User Experience answer
the real question when
experience is not optimal
What could we change to
make the experience easier and more
nice for the user
in the background the most conventional way
to evaluate the experience
users what it does is that
it assumes that the user
it is like a black box
trying to understand what is happening
in the woods but we really
not what goes into the box
me my passion my work I aim to
see through the box without breaking it
without us open without breaking
but also automatically understand
the experiences of users at
emotional and cognitive and what are
advances in technology
signal processing acquisition
same artificial intelligence
paves the way for our ability
to use this data mega deposit
human you generate by
interaction with technology
appropriate statistical techniques
it possible to predict with
reliability emotion experienced by
Users just when
it manifests
Let me give you an example
taking the facial emotions but
can predict the emotion of a
human by measuring the contraction
certain muscles and literature in
this area there goes up lens
darwin example I’ll five daughters
if he puts the literature
research has shown that
muscle contraction thalys forehead
the briber are typically this has
in surprise emotions while
contraction of the zygomatic explains Ms.
years seated emotions of pleasure
traditionally is able to
accurately measure the contraction
his muscles were needed place
Sensors all over the face
the user
so it was clearly intrusive and it
breaks the authenticity of the interaction
between the human and the machine in me
my research I rely simply
Hunger is capable of measuring
automatically these emotions there without
interfere with the very high Nature
antic interaction but today
with with a simple webcam and a
Specialized software can
to automatically measure without
sensor emotion experienced by a
User very precisely
take the example of our user
on our website
and what we are able to see s
he knows exactly 17 seconds
early 20 clear navigation
the user has had a fun time
there is something happening that
may have found what they were looking
on the website
but moments later
exactly thirty two seconds a
thing wrong
is detected and the obvious pleasure
if you hate this feeling
the negative with many
Users in our experiments
but is beginning to see an element of
answer to the question when
the interaction of people die but
right here in the example we just
generate the throne mas with data
it is very difficult in reality to
a designer to be able to use
these technologies there to help
make design decisions
eg me in my work
when experienced with
twenty participants
may accumulate 30 to 50 gigabytes
data for a single experiment
remember this is the 30 to 50 years
and cigarette 10 is Britannica
equivalent to a semi-trailer
emotions since five years with my
collaborators was measured
the emotional experience of thousands
Users interact with the
technology and we accumulated
several dozen of The Rabeats
human emotions data
enough to fill the Library of
US Congress in which the IDPs
emotional is considerable
data is too large to
allow designers of
designers to use this data
could able to take
Desert decisions I work
designers every day and they
no need answers now
after six months of mega analyzed
4,000 employees this data
we developed its ways
to represent the motions based
the eyes of a user on the screen
so we recently patented a
technology to do so and
for I will illustrate wanted
present this beautiful frittata
Mediterranean could you please
take a few moments to
view the page and imagine yourself
preparing this wonderful meal
tonight at home so our
laboratory
we have access to equipment that is
Appoints kilometers to 15 km it
allows to record with great
precisely the look of a user
in its interaction with
km interface helps produce
analyzes like the one that allows
produce a heat map
attentional diagram you see
Here is, for example red
the place that was the most watched
in trains by the group
Users who looked
So what might be concluded by
example here is that people have
petain past the immense image of
dishes prepared and focused their
focus mainly on the instructions
paris club after it makes sense
the designer could use
results this analysis and conclusion
that there should be more emphasis on
instructions and may reduce
the image when crossed against
attentional information and
emotionally it’s a different
story that are told that
you see here what we developed
my staff is a map
emotional heat that it
provides on screen what you see
is essentially what is the source of
emotion when the eyes of
individuals and the story is
completely different
we find that the picture and generates a
obvious pleasure in the page that then
instructions generates a high of
pleasure
in the background there what happened to the
People are tense on the page saw the
beautiful image are told we really air
good one continues to read instructions
life where it will be difficult to
to prepare
So you see how it is
important to take into account the
emotions in design
because if we do not take into account
emotions can really
actually make a mistake
design, but there are no indications that the
in the user experience there
Also the board eg
mental burden effort cultivates you
must turn to interact with
technology
it plays a big role in your
ability to find a technology
easy to study
I have in my laboratory a
range of technologies to
measuring accuracy
the electrical activity of your brain
to be able to measure this
mental burden but say that it is a
compact are other
indicators that can be used for is
we can inform mental load
User and of them
is the expansion of the peep and I
explains how it works
basically is that I simplify
if it takes more dilated pupil more
mental load of a person is
likely to increase
if the constant brightness which will
do an experiment here together we will
do mental arithmetic
you look in the eyes of
your neighbor you go
Specifically look stinks countries
for those who in the course of
Biology 101 is a few years
qpc as the small black bag you
have downtown
So I ask you look your
neighbor look good in the eyes is
mental arithmetic is a
great way to get to know
anyway
how much is twice three very good
easy it means how much is 14 x 17
14 x 17
do you see the pupil
dilated unless einstein to
next to you so the dilated pupil
what you have here is obviously
very useful information in
product design
one is able to measure so
fairly intrusive mental load
a person and if we had our
and provision of kilometers we would
have taken three hundred pictures in a
second, we would have had a very able
precise your villa tation two countries
What can we do with it but
with my colleagues what we
developed is a way of
represent the cocktail of emotions and
conditions experienced by users
in order to be able to compare
all products or prototypes
and to show you I you
present results of a recent
a project that led to measure
the young user experience
learner applications that use
Tablet to learn
math that’s important
the experience of the learner
this is probably a factor
important in the continuing anger
being able to have an experience
optimal in learning and what
we did here is that compared
two applications with exactly the
same level of complexity
math so it’s the same
complexity but two applications
different you will see how
Point the experience between
two applications is completely
so different to what I
present a graphic first you
So you have emotional lax in your soul
left you displeasure and
right have you liked it in
the other axis oriented vertical
you have the Committee therefore you down
have low mental load and blood
high loading
al essentially the optimal wave
developed a development
application that would be easy to
use and create an emotion
positive should probably be compatible
with persistence therefore compared Kohler
have two applications so first
Application 1
and if what you see is a cloud
points representing experience
instant every 200,000 seconds
experienced by all users who have
participated in the study you
truly an experience that is here
difficult and clearly present
let’s see the application ba
totally different experience
what you have here is objectively
bl application is easier to
use and in addition it generates a
experience is positive that
bring the child surely have
used and reused application
So in learning ways
also to compare different
prototypes and make decisions
design where one is able
really objectively compare
the experience between
users
is what one could do that
Now in real time and in life
everyday it could really
changed our society in our life
a way to learn how to
work but it is what is
occurring and e.g.
Manufacturers who have recently
marketed a computer in
which is one kilometer boarded
the case the bull is to allow
disabled people can
question only with their looks
with computer
software is used by us
Search for the detection of
emotions but they become
commercially available men on the
market but it really is not all there
will appear in the next
years of so-called self interfaces
Adaptive able to recognize
the emotion and the Committee on
users eventually able
adapt to your state’s image
imagine content providers
Media can provide you
suggestions for your mood
moment
imagine imagine autonomous cars
able to use the emotion of
driver as a warning of
security
Imagine a teacher can
automatically detecting the load
mental of its learners and adjust
teaching based on this
information
well I think it’s your
emotions that will make your devices
really smart smart thank you
