Design of Feedback and Interface for a Digital Lock
(2021) MMKM10 20211Innovation
- Abstract
- This thesis was performed in collaboration with Phoniro AB, that develops digitally unlocked products that are mainly used in home care service. The purpose of the project was to develop one of their products through a user-centered design process. To determine which product had the greatest development potential, an evaluation of three products and the associated app was conducted. A custom heuristic evaluation form was created and used to evaluate the products and the app.
After the evaluation, Phoniro's medicine cabinet was chosen to be developed with the aim of improving the user experience. Some focus was also placed on the app as the user experience is strongly dependent on the interaction between the app and the medicine cabinet....

The purpose of the project was to develop one of their products through a user-centered design process. To determine which product had the greatest development potential, an evaluation of three products and the associated app was conducted. A custom heuristic evaluation form was created and used to evaluate the products and the app.
After the evaluation, Phoniro's medicine cabinet was chosen to be developed with the aim of improving the user experience. Some focus was also placed on the app as the user experience is strongly dependent on the interaction between the app and the medicine cabinet. Through interviews with the medicine cabinet's regular users, needs were identified, and personas created.
In the development of the medicine cabinet, great focus was put on the feedback during the unlocking process, since it had no feedback implemented. Different variants of light and audio feedback, as well as an integrated light were implemented based on suggestions from the interviews. A prototype of the app was created and the unlock page was re-designed. The prototypes were tested in three iterations with a total of 13 users, and they were updated between the test rounds according to the test persons' suggestions and results. After the third round of tests, a final proposition was created, both regarding the app's interface and the cabinet’s implemented feedback. The proposition was evaluated through a final round of user tests with three users.
The results showed that implementation of both audio and light feedback was appreciated. Light feedback throughout the entire unlocking process was considered to be clearest. Yellow, flashing light was by far the most popular option for the loading process among the users, and blue for the connection process. Whether the users thought the blue light should light constantly or flash varied but the flashing light was preferred by 80 %. (Less)
