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 single-level browsing technique
called Single Window with Zoom and Replace.
This technique, common to many Geographical Information Systems presents
a global view of the entire image. In this instance, the user clicks on
a portion of the screen which is magnified and replaces the original image.
Similarly to zoom out, the user right-clicks on the screen and the image
is replaced by the original version. (Note: You cannot right-click
on a Macintosh so you are better off using an IBM pc)
What am I supposed
to do here?
Before clicking for zoom
After clicking for zoom
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 (left-)mouseclicking them and zooming
out by right-mouseclicking. 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 have to 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.
