Introduction
 
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 red outline)
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
 
Getting Started

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...

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 experiment:
