MALE SPEAKER: I would like to introduce Veronica Liesaputra,

She is working under a Google scholarship to study ebook

user interfaces, and she's going to present some work

VERONICA LIESAPUTRA: First of all, I want to say thank you

for giving me the opportunity to talk about my PhD project,

which focuses on simulating electronic documents using the

For today's talk, I'm going to explain about how to turn the

The outline of my talk will be first, I'm going to explain

about the book metaphor, the evolution of the book, users

Then I will show you my book part of example that uses one

of these page turning mechanisms, and I will

There are actually lots of debates on the

Some people believe that it is useful using the book

metaphor, because people are already familiar and have

But others believe that it's actually useless using the

They believe it actually doesn't matter how the new

Once users are familiar with it, they will no longer rely

And so they're saying, don't judge a book by its cover,

And those experts believe that only the text is important.

The physical properties of the document don't matter at all.

However this is not how humans are trained.

Our human brains are already trained unconsciously to use

the physical properties of the documents to tell us about the

Using the right text format is important, because it

essentially tells how the knowledge is organized and

presented, which in turn affects how you serve reading

Through the 4,000 years of its history, the document format

The main motivation for this change is to find a format

that is economical, portable and user friendly.

Surprisingly, we can also find the same evolution in the

development of the electronic document formats.

So the three main document formats are scrolls,

In the scroll format, a document is represented in a

so if it's electronic, then you have web pages.

The users have to use the scroll bars to basically roll

and unroll documents to search for a passage.

Another example of the scroll format is the

It was preferred over scrolls, because when it is folded, it

An unfolded concertina is essentially a scroll,

An example of this format are the [UNINTELLIGIBLE] printing

papers at every Acrobat Readers and Microsoft Word

print preview, where users can either use the scroll bars or

the page up and down buttons to go to the next page.

A user study shows that for their short documents, users

prefer scrolls over the concertina format, because

they are already used to using scrolls longer than

However, for long documents, users actually do not prefer

to use scrolls, because they can easily get lost in the

Just moving the scroll bar slightly can change the screen

That's why they always use page up and down buttons.

Where the concertina, although it helps the user gain better

understanding of the document's logical structures,

they still find it hard to know where they are on the

document and the length of the document itself.

So that brings me to the last document format, which is the

It was preferred over the concertinas, because it uses

less material, which means that it's cheaper, it's easier

And recently, many researchers tried to simulate electronic

They found that the user gained a better understanding

about the document's logical structures, and also the user
