eZ-Mall Guide: Test Protocol

3/2/2009 Usability testing 1

Usability test script

“Thank you for participating in this usability study. We are in the process of designing an

interface for an application that provides mall information to patrons. It would also show your

current position on the map. The mall information consists of store directory information,

generating favorite lists of stores etc. On selecting a store in the directory the EZ mall guide

would highlight it for you on the map relative to your current position.

I hope you do understand we are not testing you but the application. You would be helping us

find problems that may have escaped our attention.

During the usability test we would be asking you to complete four tasks that we would give to

you in writing. For this exercise we are going to use a paper mock-up of the interface. We would

like you to use just like you would use an interface on a mobile information aide like PDA. Also

during the task we would like you to think out aloud, in terms of what you are doing, information

you are looking for, what you want to do etc. This would help us to capture the task process.

When you find something or receive confirmation of your action we would like you to tap on it to

acknowledge finding/seeing it/ or say you are done. When you make a selection on a screen and if

you find a page that says under construction, just hit the back button and we would walk you

through from there.”
