Wireless accelerator based body posture stability detection and application for meditation practitioners

Meditation is an interesting research issue for these decades. Meditation is benefit for health improvement and illness reduction. Abundant of studies from physiological and psychological point of view were made for meditation. During meditation, it is a fundamental require sitting without body movement. Novel body motion monitoring and estimation system is developed in this study. Wireless tri-axis accelerometer is used to measure the body vibration. Vibration index is developed by mean and maximum vibration derived from the square summation of three axes. 26 subjects participated for 30 minute meditation with half-lotus leg crossing posture. 13 subjects are experienced group (meditation experience >; 3 years); the other 13 subjects are starter group (meditation experience <; 3 years). Results showed that there is significant difference between both groups on the motion index either by mean or maximum vibration value (p<;0.05).
