Background research

Nowadays, sleep quality has been found that it is associated with people’s physical and mental health in addition to affecting quality of life. Low sleep quality is able to create a series of diseases, including cardiovascular disease, dementia, and diabetes [1]. Some people have a poor sleep quality result in a lack of sleep [2]. A report display that adults should have sleep between 9 to 10 hours per day [3]. On the other hand, drinks which contain caffeine and alcohol harm sleep quality [4]. People who do more exercise will easier to sleep than others [5]. Many people do not know the reason for poor sleep quality because of different factors affecting sleep quality.

Under above consideration, we noticed that smart watch plays an important role in sleep quality in people’s daily life. For instance, O. Ogbanufe at al. (2018) proposed their research contribution on how smart watch support user in recording sleep information. Their research contribution about the interactions between smart watch features and user perceptions. For example, as one type wearable device, they thought that smart watch has advantage on the ‘distance’ to users than other devices. This advantage support smart watch in detecting people’s information, including sleep quality, blood pressure and heart rate [6].

In addition, the interaction between smart watch and users are a crucial problem. It is not only associated with user experience, but also connected to how to provide more appropriate and ration services. In this case, some scholars suggested their achievements on how to perform better communication between smart watches and users. K. J. Kim thought that the shape and size of smart watch have deep impact on communication. He thought that larger screen has positive influence on hedonic. Square screen often more popular than round screen [7].
