Trainer1 : Hi, my name is Lou and this is Dori and we’d like to welcome you to our data
visualization experiment. Thank you for your participation in this experiment.
Before we begin with the training, I’m going to tell you a little bit about the
experiment we are conducting, and then have you fill out and sign release papers.
What you will be working on is a software database application called InfoZoom.
InfoZoom allows you to search through, manipulate and analyze data in a given
data set. What you will be given is a set of data, and through InfoZoom, you will
search for answers to questions regarding that data set. Once we have finished
filling out the paperwork, we will train you and introduce you to some of the
functions InfoZoom has. When our tutorial is finished, we will go to the testing
room where you will be given the chance to get familiar with InfoZoom an
answer a set of training questions. At the end of the training session, the answers
to the training questions will be discussed. Once you are familiar with InfoZoom,
the test will begin. You will be given half an hour to complete questions within a
given data set. Since there are three data sets, expect to be in testing for an hour
and a half. You will be given breaks so don’t worry. Once the testing is finished,
you will be given a questionnaire to complete and you will receive your
handsome reward.
Trainer2: Reads from Room 259 handout about documents. Shows consent forms, video
release forms, etc. ( Should take about 10-15 minutes ).
BEGIN TRAINING INSTRUCTION
Slide 1 – Title Page
Slide 2
Trainer: InfoZoom is a program that helps you do visual data mining. It achieves this by
allowing you to….( trainer can simply read from slide ).
Slide 3 – Screen shot of User Interface
Trainer: This is what the InfoZoom interface looks like. I’m actually going to open the
InfoZoom application right now so that I can refer to it as we go through this
presentation.
( Open InfoZoom application and load “dating” data set if not already done so,
then demonstrate key features )
Slide 4
Trainer: There are two variables in InfoZoom…( continue reading from slide.)
( Refer to InfoZoom. Show trainees examples of objects and attributes )
Slide 5
Trainer: InfoZoom has three types of presentation styles ( continue reading from slide ).
( Refer to InfoZoom. Display all three types of views to the trainees. )
Slide 6
Trainer: Within each presentation style, there are four important functions…( continue
reading from slide )
Slide 7 – Zooming IN/OUT
Trainer: Zooming in….Zooming out….( continue reading from slide ).
( Refer to InfoZoom. Show how the display function works by zooming in on a
specific attribute. After seeing this, in all three different views ( wide,
compressed, and overview ), zoom out to show how the zoom out function
works ).
Slide 8 - Sorting
Trainer: InfoZoom allows you to select an object, and have that object sorted ascending
or descending.
( Refer to InfoZoom. Select an object/row and click on the arrow to sort
ascending and descending. )
Slide 9 – Graphing
Trainer: To help analyze data and compare the attributes of an object, InfoZoom allows
you to graph the attributes of the object. ( Read from slide )
( Refer to InfoZoom. Select object to graph. Show various representations of
data …pie chart, bar graph, etc. )
Slide 10 – Domains
Trainer: There are three different data sets you will be working with … ( continue to
read from slide ).
( Refer to InfoZoom. Starting with the “dating” data, since it is already what
we’ve been using, identify the objects and attributes. Then move on to describe
the other two data sets. In the “cars” data set, there is an inverse relationship
with respect to acceleration. The higher the value, the slower a car accelerates.
This should be explicitly discussed during the training session. For the
“environment” data set, the X and Y values represent coordinates of particular
places in Sweden.
Continue along these lines in describing the data set. )
Slide 11 – Dating Question
( Refer to InfoZoom to solve question. Go through process of acquiring the
answer to give trainees an idea of how they will be solving such questions. )
Slide 12 – Car Question
( Refer to InfoZoom to solve question. Go through process of acquiring the
answer to give trainees an idea of how they will be solving such questions. )
Slide 13 – Environment Question
( Refer to InfoZoom to solve question. Go through process of acquiring the
answer to give trainees an idea of how they will be solving such questions. )
Slide 14 – Summary
Slide 15 – Final Comments
