Task
Instructions
In this
test, you are going to perform three different tasks using Webmarking,
an application to organize web bookmarks and history files. Steps that
you take in each task are given in the following. Please feel free to
ask questions and make comments at any time during the test.
A
You organize your bookmarks using folders. Recently you have visited several
newspaper web sites and saved these sites as bookmarks. Now you are viewing
The New York Times homepage.
- Add this
page to your bookmark using the Webmarking interface
- Create
a new folder to store several newspaper web sites. Name the folder "News".
- Put the
New York Times bookmark to the "News" folder.
You remember
having visited The Financial Times homepage yesterday. But the site is
not bookmarked.
- Open
a history folder for yesterday.
- Find
The Financial Times site in the folder.
- Move
the site to the "News" folder.
B
You would like to view your history files using the "Map" view in Webmarking.
The "Map" view allows you to view your history files (pages you've visited)
in a graphical format showing not only the pages you've visited but which
pages you visited them from as well. In this case, you would like to view
all the pages that you visited from The New York Times home page.
- Go to
the "Map" view.
- Find
and select The New York Times home page as the root document in the
"Map" view.
- Find
the article of The New York Times you read which is titled "How to Separate
Good Data from Bad".
C
Webmarking allows users to conduct searches over their history and bookmark
files while also offering them a navigational interface to facilitate
browsing where searching is simply insufficient. In this scenario you
would like to perform a search to find the page from The New York Times
that you visited last week. The problem, however, is that you are not
sure when last week. You are certain that it was not Friday nor was it
Wednesday. You decide that the best way to find this page is by having
the search results displayed in the "Calendar" view so that you can go
to last week's files and see for yourself when it was.
- Open
Search dialog box.
- Search
on all pages from The New York Times. Select Calendar view as a result
view.
- Change
the view to "Week" and determine which day (not Friday and not Wednesday)
it was when you visited The New York Times.

Informed
Consent
A
group of Masters students in the School of Information Management and
Systems at UC Berkeley is conducting a study to assess the usability
of a new system for managing web bookmarks and browser history files.
If
you volunteer to participate in this study, you will be asked to perform
some tasks using a paper prototype of a computer interface. You
will be also asked to answer questions orally before, during and after
the test. A test observer will write down your comments and behaviors
while you are participating in the test.
There
are no direct benefits to you for participating other than what may
be an educational experience in viewing a new interface to organizing
web bookmarks. There are also no risks to you; you will simply
be playing with a paper prototype and answering some questions.
The results of the test will be kept confidential and not shown to anybody
in a form where you can be identified.
If
you accept these terms, please write your initials and the date here:

Logs
steps |
comments
/ behavior
|
A.
Simple adding, saving and sorting bookmarks and folders |
1.Add
this page to your bookmark using the Webmarking interface |
-
no instructions - need labels or something which tell a user what
s/he can do
- which
folder the new bookmark is added? (not recognizing the root folder
"bookmarks")
- nice
if a dialog box comes up when a new bookmark is added to modify
title and add descriptions
- don't
want to have too many dialog boxes. ok with the current way (the
current web page is directly added to the root "bookmark" folder)
but want to modify the title and/or description later
|
2.
Create a new folder to store several newspaper web sites. Name the
folder "News". |
-
description of the folder (can be typed in the new folder dialog)
should be displayed as tool tip text.
- went
to menu bar not icon
- hit
enter key (not "ok" button) to close dialog box
|
3.
Put related bookmarks to the "News" folder. |
-
all test users idicated to use "drag & drop" (not implemented
in this prototype)
|
4.
Open a history folder for yesterday. |
-
what icons with "B" and "H" mean?
- why
need to use different icons "B" and "H"?
- using
day of the week is not intuitive (Today - Monday - Sunday) - better
use date
- maybe
the opposite order is better - today's folder comes at the button
of the tree
- day
of the week is better than date
|
5.
Find The Financial Times site in the folder. |
|
6.
Move the site to the "Newspaper" folder. |
-
all test users idicated to use "drag & drop" (not implemented
in this prototype)
|
B.
Browsing with History Map view |
1.
Go to the "Map" view. |
- in
addition to tabs at the bottom of the page, want to have "view"
menu in the menu bar
- eyes
don't go to the tabs at the button of the page - should add "view"
menu
- move
tabs at the top or left of the frame?
- it
is not obvious which tab (view) is selected - use more flashy
color for selected tab
|
2.
Find and select The New York Times home page as the root document
in the "Map" view. |
- relations
between pages displayed as icons are not clear
- not
easy to understand what the map is showing - sequential order?
but the way people navigate the web is not really sequential
- want
to see more information about each page
- how
about showing descriptions (full title, description, time visited)
when user clicks on an icon as in the list view of cha-cha
- how
about using arrows to show the order of pages not just lines
- better
to have a map which goes from top to button rather than from left
to right
|
3.
Find the second page of one of the articles you read. |
- the
scenario is not good - what is the "second" article?
- need
to see more information on each site
|
C.
Power search history records in calendar view |
1.
Open Search dialog. |
-
two users immediately went to the search icon on the tool bar
- the
other went to the menu bar
|
2.
Search on all pages from The New York Times. Select Calendar view
as a result view. |
-
what should I search for?
- cool!
|
3.
Change the view to "Week" and determine which day (not Friday and
not Wednesday) it was when you visited The New York Times. |
-
don't think I am going to use calendar view as a result view
- how
can I specify which week to show?
- really
neat!
|
Overall |
|
-
bookmark and history files behave differently - e.g. history file
cannot be deleted (but can be moved (copied) to bookmark) sometimes
want to delete/edit history (current browsers allow users to delete
items from history)
- want
to see more text on the interface - there is not enough instruction.
e.g. add label "view" to combo box to change calendar views
|

situations are counted as "errors" in this measurement;

Since test
users and an evaluator talk while users perform tasks, we couldn't measure
the accurate task completion time in this testing. Instead, we measured
it by relative measures, "quick" "moderate" and "slow,"
to see how easy to complete a certain task or how intuitive our interface
is.
Numbers

category.
