Abstract
The purpose of this study is to realize the comfortable swinging fitted in the condition of the individual. A simple active rocking chair changing the driving force with heartbeat fluctuation is developed. The rocking chair is driven by a solenoid for safety and silence. The time in which the solenoid operates is proposed that the time is lengthened so that the stimulation may strengthen as the heartbeat period of human sitting on the chair lengthens, and the time is shortened so that the stimulation may weaken as the heartbeat period shortens. Then, the swing is evaluated using the 16 scales questionnaire. And it is confirmed that the comfortable swinging had been realized by the active rocking chair changing the driving force with heartbeat fluctuation. Especially, the evaluation for "the feeling of lively" with low evaluation in the uniform swing is high by fitting the swing in the condition of the individual.
