Objectives
Narrative objectives1 Some patients with chronic pain report that their pain is fluctuated intermittently in daily living. The exacerbation of pain is caused by various exacerbation factors, which can be classified into environmental, physiological and psychological factors. Conventional studies suggested that association between these factors and pain exacerbation. However, these studies did not pay attention to records for correlating exacerbation factors, time and patient personalities.
The purpose of this study is to develop an assistive system for recording symptoms of chronic pain in order to find the relation regarding exacerbation factors. We analyze data recorded by the system, and then elucidate both the specific exacerbation factors in each patients and the common factors in patients with chronic pain.

Assessment
Primary outcomes 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.
Key secondary outcomes 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.

Interventions/Control_1 We implement several interfaces as a part of the assistive system for recording symptoms of chronic pain and their related data. These interfaces of assistive system are composed of smart devices, input devices and wearable devices. The system will record symptoms of chronic pain and their related data which are correlated by date and time.
As a preliminary test, healthy subjects will use the system for a week and then the usability of these interfaces is evaluated by questionnaires and interviews with participants. After a preliminary test, patients will use the system for four to twelve weeks and then the usability of these interfaces is evaluated by questionnaires and interviews with participants.
