This is just the same thing on a screen.

Ovdje je riječ o istoj stvari
samo na zaslonu

00:50
Something happened in the 70s
13

U 70-ima se dogodilo nešto
00:52
that is sometimes referred
to as "the software crisis,"

puno brže nego je to itko očekivao
01:01
from a design perspective.

iz dizajnerske perspektive.
01:02
People were using percent-done
indicators in different ways.

18
50841

Ljudi su koristili indikatore napretka
na različite načine.

01:07
So you might have a graphical

01:15
But no one had done
a systematic survey of these things

22
63081

Međutim, nije postojalo
sustavno istraživanje o toj temi
sustavno istraživanje o toj temi
koje bi odgovorilo na pitanje:
01:18
and tried to figure out:
23
66698
1183
01:19
How do they actually affect
the user's experience

24

Kakav je uopće utjecaj
takvih traka na korisničko iskustvo

01:23
of sitting at the computer?

01:24
This graduate student named Brad Myers,
26
72391
1950
Upravo je zato postdiplomac Brad Myers
01:26
in 1985, decided he would study this.
27
74365
3234
1985. godine odlučio napraviti
svoje istraživanje.
svoje istraživanje.
01:29
He found that it didn't really matter
28
77623
2053
Saznao je da zapravo uopće nije važno
01:31
if the percent-done indicator
was giving you the accurate percent done.
was giving you the accurate percent done.
29
79700
5106
prikazuje li nam traka
točan postotak napretka.
točan postotak napretka.
01:36
What mattered was
that it was there at all.
that it was there at all.
30
84830
2730
Važno je da se traka napretka
uopće prikazuje.
uopće prikazuje.
01:39
Just seeing it there
made people feel better,
made people feel better,
31
87584
2604
Ljude usrećuje već i
sama činjenica da je tamo
sama činjenica da je tamo
01:42
and that was the most surprising thing.
32
90212
2689
što je bilo najveće iznenađenje.
01:44
He has all these ideas
about what this thing could do.
about what this thing could do.
33
92925
2919
Myers je imao pregršt ideja
kako bismo je mogli koristiti.
kako bismo je mogli koristiti.
01:47
Maybe it could make people
relax effectively.
relax effectively.
34
95868
4086
Možda bi ljudima mogla
osigurati učinkovitije opuštanje.
osigurati učinkovitije opuštanje.
01:51
Maybe it would allow people
to turn away from their machine
to turn away from their machine
35
99978
4670
Možda bi ljudima mogla
omogućiti da se nakratko odvoje od uređaja
omogućiti da se nakratko odvoje od uređaja
01:56
and do something else
of exactly the right duration.
of exactly the right duration.
36
104672
3063
i rade nešto drugo
što oduzima točno toliko vremena.
što oduzima točno toliko vremena.
01:59
They would look and say,
"Oh, the progress bar is half done.
"Oh, the progress bar is half done.
37
107759
2881
Pogledali bi i zaključili:
"Traka napretka je na pola puta.
"Traka napretka je na pola puta.
02:02
That took five minutes.
38
110664
1151
Trebalo joj je 5 minuta.
02:03
So now I have five minutes
to send this fax,"
to send this fax,"
39
111839
3897
To znači da sad imam 5 minuta
za slanje onog faksa",
za slanje onog faksa",
02:07
or whatever people were doing in 1985.
40
115760
2364
ili čime god su se ljudi
već bavili davne 1985.
već bavili davne 1985.
02:10
Both of those things are wrong.
41
118148
1804
Obje ideje bile su pogrešne.
02:11
Like, when you see that progress bar,
42
119976
1866
Naime, kad vidite traku napretka,
02:13
it sort of locks your attention
in a tractor beam,
in a tractor beam,
43
121866
2967
odmah vas u potpunosti zaokupira
02:16
and it turns the experience of waiting
44
124857
2016
te iskustvo čekanja pretvori
02:18
into this exciting narrative
that you're seeing unfold in front of you:
that you're seeing unfold in front of you:
45
126897
5082
u uzbudljivu priču
čiji rasplet gledate uživo ispred sebe.
čiji rasplet gledate uživo ispred sebe.
02:24
that somehow, this time you've spent
waiting in frustration
waiting in frustration
46
132003
3849
Vrijeme potrošeno na čekanje i frustraciju
02:27
for the computer to do something,
47
135876
1635
dok računalo radi svoj posao,
02:29
has been reconceptualized as:
48
137535
1975
pretvoreno je u nešto
sasvim drugačije:
sasvim drugačije:
02:31
"Progress! Oh! Great stuff is happening!"
49
139535
2294
"Napredak! Sjajne se stvari događaju!"
02:33
[Progress...]
50
141853
2138
[Napredak...]
02:36
But once you start thinking
about the progress bar
about the progress bar
51
144015
3215
Međutim, jednom kad počnete
razmišljati o traci napretka
razmišljati o traci napretka
02:39
as something that's more
about dulling the pain of waiting,
about dulling the pain of waiting,
52
147254
3345
kao o nečemu što služi za
ublažavanje boli čekanja,
ublažavanje boli čekanja,
02:42
well, then you can start fiddling
around with the psychology.
around with the psychology.
53
150623
3883
možete se poigrati s psihologijom.
02:46
So if you have a progress bar
that just moves at a constant rate --
that just moves at a constant rate --
54
154530
4048
Ako primjerice imate traku napretka
koja se kreće konstantnom brzinom,
koja se kreće konstantnom brzinom,
02:50
let's say, that's really
what's happening in the computer --
what's happening in the computer --
55
158602
2976
jer recimo odražava
stvarni napredak računala,
stvarni napredak računala,
02:53
that will feel to people
like it's slowing down.
like it's slowing down.
56
161602
3257
ljudi će imati osjećaj da usporava.
02:57
We get bored.
57
165668
1286
Postat će nam dosadno.
03:00
Well, now you can start
trying to enhance it
trying to enhance it
58
168002
2107
Sad je možete početi unapređivati
03:02
and make it appear to move
more quickly than it really is,
more quickly than it really is,
59
170133
2762
i prikazati brži napredak
nego što je to uistinu slučaj,
nego što je to uistinu slučaj,
03:04
make it move faster at the beginning,
like a burst of speed.
like a burst of speed.
60
172919
3707
pobrinuti se da krene brže na početku,
kao da je dobila nalet energije.
kao da je dobila nalet energije.
03:08
That's exciting, people feel like,
"Oh! Something's really happening!"
"Oh! Something's really happening!"
61
176650
3344
To je uzbudljivo i ljudi će pomisliti:
"To! Nešto se uistinu događa!"
"To! Nešto se uistinu događa!"
03:12
Then you can move back into a more
naturalistic growth of the progress bar
naturalistic growth of the progress bar
62
180018
4029
Zatim se možete vratiti
prirodnijem napretku trake
prirodnijem napretku trake
03:16
as you go along.
63
184071
1311
kako prilazi kraju.
03:17
You're assuming that people are focusing
on the passage of time --
on the passage of time --
64
185406
3194
Pretpostavljate da se ljudi koncentriraju
na prolazak vremena,
na prolazak vremena,
pokušavaju gledati travu kako raste,
03:20
they're trying to watch grass grow,
65
188624
1703
03:22
they're trying to watch a pot of water,
waiting for it to boil,
waiting for it to boil,
66
190351
2980
pokušavaju gledati lonac pun vode
čekajući da proključa,
čekajući da proključa,
03:25
and you're just trying
to make that less boring,
to make that less boring,
67
193355
2392
i pokušavate cijeli proces
učiniti što zanimljivijim,
učiniti što zanimljivijim,
03:27
less painful and less frustrating
68
195771
2226
bezbolnijim i manje frustrirajućim
03:30
than it was before.
69
198021
1326
nego što je bio ranije.
03:31
So the progress bar at least gives you
70
199371
3001
Traka napretka vam barem daje neku vrstu
03:34
the vision of a beginning and an end,
71
202396
2461
prikaza početka i kraja
03:36
and you're working towards a goal.
72
204881
1694
i dojam da napredujete prema cilju.
03:38
I think in some ways,
it mitigates the fear of death.
it mitigates the fear of death.
73
206599
2953
Mislim da na neki način
ublažava strah od smrti.
ublažava strah od smrti.
03:44
Too much?
74
212079
2111
Previše?
