MID-FI PROTOTYPE

We created mid-fi prototype in Axure. First part was for mobile interactions and second part was for smart watch interactions.

• First Iteration – Mid-fi prototype

Testing the Mid-fi Prototype

We conducted four observations to determine the usability of our app. We asked the participants to complete a series of six tasks. The first four tasks were for the mobile interactions and the last two tasks were for the smart watch interactions.

Participants were instructed to think aloud when completing the tasks. After completion, participants were asked for suggestions for improving the application.

Participants information

Data

Observation data was collected from each participant during a 15 minutes testing session with an observer. The data was analyzed for similarities between users

Observations for App

Observations for smart watch

Findings

All of the users were able to complete all of the tasks presented to them with minimal difficulty (no more than 1 error per task). Despite this, the users mention some pain points that should be considered in future iterations.

• Users were confused about the calendar feature on the app.
  • Two were confused about the icon.
  • One was confused about the use of the calendar while driving.
  • One was confused by the layout.
• Users expected the message to send automatically without tapping the send button.
• Two users pointed out that the hang-up button in the watch screen interface looks like a call button since the phone icon does not face downward.
• Users were concerned about the size of the buttons. Most suggested to make the buttons bigger.

Based on the users’ feedback the following changes were made to the first prototype:

• Mobile
  • Automatically send message after selecting the message.
  • Add option to create new message
  • Add names to icons on the menu
  • Add title to the custom message screen
  • Use icons on the navigation screen
• Smart Watch
  • Increase button size
  • Change hang-up button

• Second Iteration – Mid-fi prototype

Conclusion

Safeable aims to make communicating while driving a safer experience for its users. Based on this first round of testing of the application, we still have some improvements to make in order to achieve this goal. Although all users were able to successfully complete the tasks presented to them, the experience was not seamless enough to ensure the user can safely operate the app while driving. Being that safety is the most important concern of Safeable, future iteration of the application must strive for an optimal user experience by fixing factors that cause the user to hesitate, such as icon choices, menu options, and button sizes. Our testing also was also impacted by certain limitations such as small sample size and observer bias. By continuing to test future iterations of the application we can help mitigate these problems.
