| Outline of Final Research Achievements |
The public concern has been raised that prolonged usage of smartphone could lead to users' constraint postures and physical inactivity, resulting in development of neck and shoulder discomforts. The objective of the study is to confirm the association between risk factors of psychological restraint on smartphone usage and musculoskeletal disorders of the neck. As a first step toward achieving the objective, we developed a smartphone based application for recording time-series data from the sensors embedded on smartphone. To evaluate the reliability of data obtained from built-in sensors, analyses of sensor precision and accuracy were performed. The results showed a high level of stability and reliability of built-in sensors on smartphones, indicating that the smartphone based application has great potential to be applied in ergonomics or epidemiological research.
