The document describes a scenario of a building inspector named Harri. Harri uses a point-of-view camera and tablet to record inspections and fill out inspection sheets. He attaches photos and video clips from inspections to the relevant sections of the inspection sheet. Harri finds that including rich media helps him remember and revise findings, and customers also find the multimedia inspection sheets useful.

5. Harri,
a
building
inspector
offers
his
services
for
several
constructors
and
during
inspec7on
visits
he
o8en
cannot
meet
the
people
responsible
for
each
phase
and
site.
When
he
inspects
a
building,
Harri
records
everything
with
a
point-­‐of-­‐view
camera.
He
also
has
his
inspec7on
sheet
on
a
tablet
where
each
area
or
part
is
connected
to
the
people
responsible
of
that
area.
During
inspec7on,
Harri
uses
a
tablet
to
fill
the
inspec7on
sheet.
Whenever
he
takes
a
snapshot,
it
is
added
to
currently
ac7ve
area
in
the
inspec7on
sheet.
He
o8en
also
takes
7me
to
explain
aloud,
alone
or
for
the
building
foreman,
his
evalua7on
of
the
build
quality.
A8er
the
visit
Harri's
voiced
evalua7ons
are
split
into
the
inspec7on
sheet
as
video
clips.
These
clips
are
aGached
to
the
part
of
inspec7on
sheet
that
was
ac7ve
during
the
explana7on.
Harri
reviews
the
clips
and
removes
a
few.
Parts
of
the
inspec7on
sheets
with
possible
addi7onal
explana7ons
from
Harri
are
forwarded
to
the
people
responsible
for
the
work.
Harri
finds
that
the
rich
media
material
makes
it
easier
for
him
to
remember
and
revise
his
findings
about
the
building
and
the

are

the

as

9. 3. DISSENY BASAT EN ESCENARIS
• Afavoreixen la reflexió sobre els problemes de disseny.
• Els escenaris són alhora concrets i flexibles, ajudant als desenvolupadors a
gestionar la fluïdesa de les situacions de disseny.
• Possibiliten diversos punts de vista d’una mateixa interacció.
• Es poden abstreure i ser categoritzats.
• Faciliten la comunicació centrada en el treball entre les diverses parts
implicades en el disseny.
5 motius a favor de l’ús d’escenaris en el procés de disseny (Carroll, 1999):

10. 4.TIPUS D’ESCENARIS
• Escenaris sobre problemes: descriuen les característiques de la situació actual.
• Escenaris d’activitat: proposen la transformació de la pràctica actual en noves
característiques de disseny
• Escenaris d’informació: centrats en com els usuaris perceben, interpreten i
entenen la informació
• Escenaris d’interacció: accions físiques i respostes del sistema que responen als
objectius i les necessitats de les tasques de l'usuari.
Segons Rosson i Carroll (1999):

History teacher Jana
Jana
is
a
history
teacher
in
a
small
primary
school
in
Poland.
She
just
graduated
from
the
university
last
spring,
so
it
is
her
first
year
as
a
teacher.
Jana
is
a
very
concerned
teacher
and
wants
to
make
her
lessons
interes7ng
for
the
students.
She
has
been
using
computers
for
years
-­‐
mainly
for
university
studies
and
communica7ng
with
friends.
She
is
also
interested
to
use
Internet
and
ICT
tools
with
her
students.
In
6th
grade
history
lessons
are
focused
on
the
Middle
Ages.
Currently
Jana
is
preparing
a
lesson
about
life
in
medieval
ci7es.
She
looks
for
addi7onal
informa7on
from
Polish
Wikipedia
and
Google.
Wikipedia
has
good
ar7cles
on
Polish
ci7es,
but
it
lacks
the
detailed
informa7on
about
medieval
7mes.
Jana
remembers,
that
one
of
her
colleagues
was
talking
about
Toolbox.
She
finds
Toolbox
from
Google
and
starts
to
browse
the
website.
Toolbox
has
a
good
selec7on
of
learning
resources,
which
are
all
tagged
with
keywords.
Jana
is
searching
for
history
and
receives
several
hundred
results.
Maybe
there
is
something
on
medieval
ci7es
too?
New
search
gives
only
a
dozen
results.
Some
photos,
some
slide
shows
and
