Outcome

• Received an A grade on the full report and the professor referred to the report as a good example for other groups

• The most noteworthy task-based and interface-based findings summarized below:

Task-based findings

• Locate the "Quiz" tab

  • Participants were asked what they would do if they wanted to refresh their First Aid/CPR knowledge and make sure they knew what to do. We wanted to know which tab they would use to check that they have retained the knowledge. All 4 participants failed to go to the Quiz tab. All 4 went to the Learn tab as they wanted to relearn the information. One of them didn’t even notice the Quiz tab initially and said would either use the Learn or Emergency tab.

  • Takeaway: Place the “Quiz tab”” or quiz section inside of the Learn tab. At the end of each educational topic within the learn section, there should be a link or a button that allows users to easily take a quiz to see if they retained what they learned in the “Learn” tab.

• Get directions to a hospital with an emergency room

  • The participants were asked to get directions to a hospital with an emergency room. Although only 2 of the 7 participants failed to correctly complete this task because they didn’t notice the ER symbol in the list of hospitals, all 7 participants mentioned that the ER was too small. In fact, 2 participants who correctly completed this task did not notice the ER label at first and only once they noticed it, did they correctly identify the nearest hospital with an ER.

  • Furthermore, of the 7 participants, 5 of them had difficulty getting directions because they were unsure what to click on to bring up Google Maps/Apple Maps app. This interface gave users the impression that they would be able to tap the map to be taken to a maps app, but the interaction behavior was inconsistent.

  • Takeaway: The difference between emergency and non-emergency use cases on this app is important to remember, because the emergency use case suggests the high priority of being able to get directions to a hospital that has an emergency room. However, the ER label on each hospital is easily overlooked, and the difference between these two types of hospitals (with or without an emergency room) is not properly emphasized. Additionally, the interface with contact information for each hospital should provide clearer affordances of how to open the directions.

Interfaced-based Findings

• Emergency Tab

  • Finding: In an emergency situation, many users commented that it would be very unlikely that they would read text due to the stressful nature. Experienced users noticed that key information were left out of the steps if a naive user were using this app as a reference. For example, there is a certain position to hold a baby when administering back and chest thrusts if they are choking. The image on the left is not provided in the “Emergency” tab on the right.

  • Recommendation: It would be ideal if the graphics provided in the “Learn” tab remained in the “Emergency” tab. This could provide visual cues to the user rather than solely text.
