User Study Practice

Ask the experimenter to load the User Study diagram. With this diagram you will practice using Deep View. After the practice you will complete similar tasks on other diagrams.

This is an example of a flow chart that shows a procedure. The procedure is divided into tasks. Links indicate how progress is made from one task to another.

After reading about the diagram, the experimenter will work with you to demonstrate how to use Deep View to navigate the diagram.

To get you started, here is an overview of the diagram is as follows:

Detailed description of diagram

This is a flow chart describing the tasks a participant completes in the user study.

A participant starts the study and completes the informed consent.
Next the tasks are different for a sighted and blind participant.
The sighted participant completes the study using a visual drawing program, Rational Rose.
A blind participant uses our custom audio diagram interface, Deep View.
After using the interfaces, participants complete the post questionnaire and end the study.

Practice navigation

The experimenter will review how to navigate the diagram.
Take some time to navigate the diagram and become familiar with the diagram.
When you are ready, the experimenter will ask you 3 questions about the diagram.

Practice editing

Deep View provides an extensive interface to edit diagrams. In the study you will only need to add links between nodes.

To add a link, press Control + L. A dialog appears in which you enter the information about the link.
The name is optional and would describe the nature of the link.
For this diagram a link indicates how progress is made from one node (or task) to another node (or task).
An example, there is a link from the first task where a participant starts the study to the second task where the participant completes the informed consent.

Let us practice. The experimenter will delete the just mentioned link and you can recreate it.
The link is between the task where a participant starts the study and completes the informed consent.

Practice pointing

Next we will practice pointing at nodes in the diagram.
You will point at nodes to answer questions asked by the experimenter.

To point at a node, select the node and press Control + P.
The experimenter will see what you are pointing at.

To view what is pointed at, press Control + Shift + P.
This changes the Deep View mode to show a list of items pointed by you and the experimenter.
Press delete to return to regular mode of viewing the complete diagram.

Let us practice. The experimenter will ask you two questions.
