MiNap: Smartwatch-Based Sleep Diary Application: Empowering Sleep Research with Digital Data Collection

Abstract

MiNap is a smart watch application to serve the purpose of a sleep diary. Designed to replace conventional paper-based sleep diaries, MiNap embodies the fusion of technology and research objectives, facilitating the seamless transition from analog to digital sleep data collection.Researchers in this field study the different stages of sleep, sleep patterns, circadian rhythms, and the underlying causes of sleep disorders. They also explore the impact of sleep disorders on mental health, cardiovascular health, neurological disorders, and other medical conditions. Researchers are now utilizing consumer-grade wearable devices to track sleep, but current devices have limitations around recognizing the time when a participant falls asleep and wakes up.As opposed to other sleep tracking technologies, MiNap Smartwatch application helps to mitigate the limitation of figuring out when a person falls asleep vs. if they are using their phone in bed or wakes up. The simple UI only requires the participant to click on a button while about to sleep and once after waking up, promising more compliant and better data collection. MiNap can thus replace paper sleep diaries. Summary: MiNap consists of a Smartwatch and Smartphone Application, sharing the same backend resources. The Smartwatch app, built in Swift, simplifies sleep session recording and stores data in DynamoDB. The Mobile app, using React Native, offers cross-platform access to sleep data and surveys. AWS DynamoDB handles data storage, with two main tables: Authentication and Sleep Session. Data sync between AWS and Oracle SQL relies on a Docker script. AWS Amplify simplifies resource setup for both apps, ensuring smooth integration. In conclusion, MiNap's architecture, driven by AWS services and Amplify, streamlines sleep data management for research participants, providing a user-friendly experience.
