Design outcomes

Primary

Measure	Time frame
We implement several interfaces as a part of the assistive system for recording symptoms of chronic pain and their related data. These interfaces are composed of smart devices, input devices and wearable devices. Primary outcome is the usability of these interfaces for integrating into the system. The usability of these interfaces is evaluated by questionnaires and interviews with participants.	—

Secondary

Measure	Time frame
The promising cause of chronic pain exacerbation factors will be analyzed after four to twelve weeks system use, by contrast with the questionnaires and the change in the other related data (e.g. atmospheric pressure). These are correlated by date and time. Key secondary outcome is results in recording data analysis. The results are associated with the relationship between an exacerbation of pain and its factors, and between the exacerbation and the degree of environmental factor changes.	—
