How many people are bored at their desk

Koliko se ljudi dosađuje za svojim stolom,

for how many hours every day

koliko sati dnevno,

and how many days a week and how many weeks a year

koliko dana tjedno, koliko tjedana godišnje

for how many years in their life?

koliko godina u svom životu?

[Small thing. Big idea.]

[Mala stvar. Velika zamisao.]

[Daniel Engber on the Progress Bar]

[Daniel Engber o traci napretka]

The progress bar is just an indicator on a computer

Traka napretka na računalu samo nam daje do znanja

that something's happening inside the device.

da se nešto događa unutar uređaja.

The classic one that's been used for years is a horizontal bar.

Klasična verzija koja se koristi već godinama je vodoravna traka.

I mean, this goes back to pre-computer versions of this

Pojavila se u raznim oblicima i prije samih računala

on ledgers, where people would fill in a horizontal bar from left to right

kad su ljudi u poslovnim knjigama ispunjavali traku s lijeva nadesno

to show how much of a task they had completed at a factory.

kako bi prikazali količinu odrađenih zadataka u tvornici.

This is just the same thing on a screen.

Ovdje je riječ o istoj stvari samo na zaslonu

Something happened in the 70s

U 70-ima se dogodilo nešto

that is sometimes referred to as "the software crisis,"

što se ponekad naziva "softverska kriza",

where suddenly, computers were getting more complicated

vrijeme kad su računala odjednom postala sve kompliciranija

more quickly than anyone had been prepared for,

puno brže nego je to itko očekivao

from a design perspective.

iz dizajnerske perspektive.

People were using percent-done indicators in different ways.

Ljudi su koristili indikatore napretka na različite načine.

So you might have a graphical countdown clock,

Koristili su se grafički prikazi sata za odbrojavanje

or they would have a line of asterisks

ili linija zvjezdica

that would fill out from left to right on a screen.

koja bi ispunjavala zaslon s lijeva nadesno.

But no one had done a systematic survey of these things

Međutim, nije postojalo sustavno istraživanje o toj temi

and tried to figure out:

koje bi odgovorilo na pitanje:

How do they actually affect the user's experience

Kakav je uopće utjecaj takvih traka na korisničko iskustvo

of sitting at the computer?

sjedenja za računalom?

This graduate student named Brad Myers,

Upravo je zato postdiplomac Brad Myers

in 1985, decided he would study this.

1985. godine odlučio napraviti svoje istraživanje.

He found that it didn't really matter

Saznao je da zapravo uopće nije važno

if the percent-done indicator was giving you the accurate percent done.

prikazuje li nam traka točan postotak napretka.

What mattered was that it was there at all.

Važno je da se traka napretka uopće prikazuje.

Just seeing it there made people feel better,

Ljude usrećuje već i sama činjenica da je tamo

and that was the most surprising thing.

što je bilo najveće iznenađenje.

He has all these ideas about what this thing could do.

Myers je imao pregršt ideja kako bismo je mogli koristiti.

Maybe it could make people relax effectively.

Možda bi ljudima mogla osigurati učinkovitije opuštanje.

Maybe it would allow people to turn away from their machine

Možda bi ljudima mogla omogućiti da se nakratko odvoje od uređaja

and do something else of exactly the right duration.

i rade nešto drugo što oduzima točno toliko vremena.

They would look and say, "Oh, the progress bar is half done.

Pogledali bi i zaključili: "Traka napretka je na pola puta.

That took five minutes.

Trebalo joj je 5 minuta.

So now I have five minutes to send this fax,"

To znači da sad imam 5 minuta za slanje onog faksa",

or whatever people were doing in 1985.

ili čime god su se ljudi već bavili davne 1985.

Both of those things are wrong.

Obje ideje bile su pogrešne.

Like, when you see that progress bar,

Naime, kad vidite traku napretka,

it sort of locks your attention in a tractor beam,

odmah vas u potpunosti zaokupira

and it turns the experience of waiting

te iskustvo čekanja pretvori

into this exciting narrative that you're seeing unfold in front of you:

u uzbudljivu priču čiji rasplet gledate uživo ispred sebe.

that somehow, this time you've spent waiting in frustration

Vrijeme potrošeno na čekanje i frustraciju

for the computer to do something,

dok računalo radi svoj posao,

has been reconceptualized as:

pretvoreno je u nešto sasvim drugačije:

"Progress! Oh! Great stuff is happening!"

"Napredak! Sjajne se stvari događaju!"

[Progress...]

[Napredak...]

But once you start thinking about the progress bar

Međutim, jednom kad počnete razmišljati o traci napretka

as something that's more about dulling the pain of waiting,

kao o nečemu što služi za ublažavanje boli čekanja,

well, then you can start fiddling around with the psychology.

možete se poigrati s psihologijom.

So if you have a progress bar that just moves at a constant rate --

Ako primjerice imate traku napretka koja se kreće konstantnom brzinom,

let's say, that's really what's happening in the computer --

jer recimo odražava stvarni napredak računala,

that will feel to people like it's slowing down.

ljudi će imati osjećaj da usporava.

We get bored.

Postat će nam dosadno.

Well, now you can start trying to enhance it

Sad je možete početi unapređivati

and make it appear to move more quickly than it really is,

i prikazati brži napredak nego što je to uistinu slučaj,

make it move faster at the beginning, like a burst of speed.

pobrinuti se da krene brže na početku, kao da je dobila nalet energije.

That's exciting, people feel like, "Oh! Something's really happening!"

To je uzbudljivo i ljudi će pomisliti: "To! Nešto se uistinu događa!"

Then you can move back into a more naturalistic growth of the progress bar

Zatim se možete vratiti prirodnijem napretku trake

as you go along.

kako prilazi kraju.

You're assuming that people are focusing on the passage of time --

Pretpostavljate da se ljudi koncentriraju na prolazak vremena,

they're trying to watch grass grow,

pokušavaju gledati travu kako raste,

they're trying to watch a pot of water, waiting for it to boil,

pokušavaju gledati lonac pun vode čekajući da proključa,

and you're just trying to make that less boring,

i pokušavate cijeli proces učiniti što zanimljivijim,

less painful and less frustrating

bezbolnijim i manje frustrirajućim

than it was before.

nego što je bio ranije.

So the progress bar at least gives you

Traka napretka vam barem daje neku vrstu

the vision of a beginning and an end,

prikaza početka i kraja

and you're working towards a goal.

i dojam da napredujete prema cilju.

I think in some ways, it mitigates the fear of death.

Mislim da na neki način ublažava strah od smrti.

Too much?

Previše?
