Habit Tracker for WP8
The Habit Tracker app is a Windows Phone 8 app that helps the users to track and establish daily habits. It was part of my master thesis and was used to evaluate emotional design as a way to improve the user experience.
The Habit Tracker app lets users create daily habits like exercising or reading. If the habit was successfully pursued on that day, it will be checked off in the calendar. Consecutive days count as a chain and will motivate users to keep the habit going.
The topic of my thesis was the exploration of emotional design for mobile apps and finding guidelines on how to use emotional design to improve the user experience. A collection of positive emotions were collected and app aspects were designed specifically to evoke certain emotions in users.
The Habit Tracker app was developed to evaluate emotional designs. Therefore, a minimal valuable version and a version with several emotional design enhancements were developed and delivered to testers. Later, the test user were interviewed about the impact of the version differences on their usage and perception of the app.
- I interviewed users about their favorite apps, enjoyable app features/designs/aspects, perceived emotions. This was supported with simple self-made emotion cards. Those helped the user to select and talk about emotions.
- A minimal valuable product (MVP) was sketched that provides the basic functionality for the app concept.
- Two design workshops were held with design students to get a more diverse set of ideas on how to design for emotions.
- Quick sketches of workshop ideas were created.
- The MVP was implemented and delivered to test users a Windows Store closed beta release.
- The enhanced version was implemented as an update for the MVP.
- Hallway usability testing was done to find and fix rough usability issues.
- Test users were interviewed about their experience after two weeks of testing.
- Targeting specific emotions can help to make an app more meaningful to the user and provide additional motivation to use it.
- Emotional design can only work if basic requirements on usability and user satisfaction are met first.
- Interviews revealed that there were some usability issues in the final prototype. Another iteration would have improved the user experience and enabled some of the emotional design aspects to strengthen their impact.
