Predict discomfort symptoms such as back pain, stiff shoulders, and headaches that occur while working in an office chair through casual continuous sensing of postural changes, etc., and explore sitting styles that allow comfortable work.
Others
To predict changes in research participants' daily headache, stiff shoulders, back pain, eye strain, and concentration and work efficiency based on time-series AI analysis data from inertial sensors attached to chairs used in the work environment and mobile cameras attached to work displays, and to identify the conditions of sitting conditions that are unlikely to aggravate discomfort symptoms.

Study participants will report discomfort symptoms, etc. (headache, stiff shoulders, back pain, eye fatigue, work efficiency: all at subjective level) four times a day using Google Form over a 10-week period. We will analyze the relationship with the sitting information obtained from sensors and cameras.
