Welcome to the experiment entitled Comparison of Single-level and
Multi-level Browsing Techniques as applied to Lifelines.
You will be using the
technique shown below which comprises of a multi-level browsing technique
called Single Co-ordinated Pair (Overview detail).
Click and drag for magnifying the required area (shown by the
After the required area is magnified on the right screen
This technique combines displays of the overview and a local magnified
view. As shown above this consists of two windows of equal sizes, the one
on the left showing the global view while the one on the right showing
the detailed view. They act as a co-ordinated pair as highlighting an area
on the left reflects the magnified view on the right.
What am I supposed
to do here?
You will be performing a series of tasks on the system shown above.
They are nothing serious, just finding answers to a series of questions,
and the way to do that is to navigate to different portions of the screen
and zooming in (when neccessary) by clicking and dragging on a portion
of the screen. The area in question is highlighted by a red rectanglular
outline, and the magnified view of the outline is shown on the right. Clicking
once more on the left screen (overview screen) restores the default view
of the screen. The question would be followed by 2 or more answers.
Using the mouse effectively on the screen, or just by plain looking at
it, decide on an answer and check the appropriate option (answer). Remember,
it is not you, but rather the interface which is being tested.
Things I should know
You have to use Interner Explorer as your browser
Your browser should be java - enabled (if you are using IE4.0, that takes
care of the first two requirements)
Your monitor should be atleast 15 inches (diagonal) in size.
You must use an IBM pc (which is basically your everybody personal computer).
The first thing is to familiarize yourself with the interface. For that,
there are two help items you can make use of :
After you are done with either version, use the "BACK" button in your
browser to come back to this page.
On with the Experiment...
Animations and Images
with the demo version For the interests of this experiment,
please do not take more than 10 minutes for your practice. Otherwise,
a significant amount of bias creeps into the experiment. However, once
you are finished, you are welcome to play with the demo version as much
as you want to.
Please note: After you start your experiment, please do not use
the back button anymore. Never mind while plodding through a series
of tasks, you find out that you have made a mistake in one of the previous
questions. Please do not go back to correct the answer, your first instinct
is the one that is most important to us. If there is such a situation,
then the fault does not lie with you, but rather with us, the designers.
In order to redeem such flaws, your mistakes are as important to us as
your correct responses. There are two things you should know about the
to the experiment beginning with Background Survery
Before you begin your tasks, you are required to fill up a background survey
form. If you do not want to divulge your name, that is fine, you can use
an alias. But please try to provide answers to the best of your knowledge
for the rest of the questions. The link below will take you to the background
survey and once you are finished with it, press the "SUBMIT" button which
will take you to the actual experiment.
You are required to fill up a subjective satisfaction questionnaire after
you are finished with the tasks. You will find a link to it once you complete
all the tasks, and press the "SUBMIT" button on the form once you fill
up the requisite information. Please remember to fill up the questionnaire,
because without it, the experiment is incomplete.
