User study

Due to the protection of patients’ privacy, we could not approach patients with Insomnia at hospitals. Therefore, we searched for alternatives who had trouble sleeping at night. Users problems and behavior were documented with Persona and Storyboard.




The challenge in ideation stage was whether to provide tangible interaction or software interface interaction to users. Tangible interaction could be more intuitive however was not able to record important detail of users’ trouble with sleeping. Software interaction enable users to record details efficiently and convenient however may had the risk to keep them awake.

As users needed to provide subjective experience to doctors, which was a significant part of treatment, we decided to focus on software interface design.



interface Design

The goal in interface design was to provide charming, interesting and efficient experience to users when recording their symptoms. The experience was helpful in releasing their pressure and anxiety.


how to use


voice recording

Compared to writing, voice recording is much faster according to scientific researches. With voice recording, users will have more time recalling and describing their symptoms in detail than with writing. Doctors will have a more comprehensive understanding of their patients.

emotion logging

Users with paper sleep diary also find it difficult to illustrate their emotion. To decrease the burden of identifying emotion. Rummi provides a wide range of selections for them. In this way, they don’t need to struggle to find the best vocabulary that match their feeling.




We invited 5 users for user tests. The feedback from users was positive as they liked the cute monster design, and voice recording was more faster than typing.




Though the product gained positive feedback from users with sleep problems. The influence of the design was unknown to insomnia people as the two users groups were different.

Voice recognition was able to record full details of the symptoms efficiently while tangible interaction could be easier and more convenient. A/B testing should be performed to evaluate which method suited the context that could solve users’ problems and meet their needs.
