Usability Testing in the Field: Measuring the "Infotainment" Value of an In-Store Touch Screen

Overview
touch screen example
In-store customer service is never a customer's definition of fun. Thus, the goal is to provide the customer with some entity that will help them pass the time in a more enjoyable fashion. In many establishments, such as the doctor's office, a TV can do the trick. In the case of the Sprint store, touch screens were provided. The touch screens contained information about phones, such as games the customer could play on the phone that they owned. The question was asked, "Are the touch screens having any affect upon the customer' perceived wait time."


Research Design


Data collection sources for measuring infotainment value
  • The primary question: Does the in-store touch screen have an impact on the following customer values?
    • Customer perceived wait time
    • Overall in-store user experience
  • Hypothesis: The graph in the upper left demonstrates the hypothesis. Perceived in-store wait time for those that use the touch screens will be lower (overall) than the actual in-store wait time, and that the perceived wait time for those that do not use the touch screens will be greater (overall) than the actual in-store wait time.
  • A few study variables
    • Store location: 3 locations
    • Self-selected use of touch screen v. no touch screen use
  • Data gathered
    • Observation of behavior and customer movement
    • Questionnaires
    • Touch screen data including start time, stop time, and pages used
    • In-store wait queue data
  • Team coordination
    • Field video recording vendor
    • Observation and questionnaire administration vendor
    • Touch screen data team
    • Wait queue data team
    • Sales Reps
  • Analysis included:
    • Answers to the primary questions
    • In-store user experience issues
    • Touch screen issues and recommendations for re-design

Accomplishments

In order to obtain the answers to the study questions, we had to integrate a large number of data points, which included three sets of data coordinated through time stamps. To reach study conclusions as to whether the touch screens were worth the cost, and to make recommendations for redesign needs is certainly a great accomplishment. While I can't provide detailed answers on our findings, the presence of the touch screens, still in stores today, may lead you to some type of conclusion.


Building on That

Understanding the wait time as a factors of the touch screens was the critical variable in this study. The next step would have been to undergo further analysis and begin to make changes to other items we identified, including changes to the touch screen user interface.
