1 Background
• We often spend one third time to sleep in our
  life. It is good for us to improve sleep quality
  for comfortable life.
• Gathering sleep data every day, we can take
  care of our condition more easily.




                                                     3
2 Purpose
• The wave which is measured from sleep
  monitoring system shows often strange value
  when we moved.
• That data is wrong to analyze data. So, we
  should detect body movement and remove it
  from waves. Then we get more exactly data.



                                                4
3.1 Data Gathering
         • To gather the data by
           using sleep monitoring
           system. Figure shows
           sensor board, bedside
           box and servers. The
           data is gathered sensor
           board under the pillow
           and the data are
           transmitted servers
           through bedside box.

                                     5
3.2 Detect Body Movement(1)
              • I am trying narrowing
                interval of body
                movement time.

              • Figure of lower right
                graph is the wave of
                heart rate and jumbling
                point happen body
                movement.


                                        6
3.2 Detect Body Movement(2)
• The body movement is
  detected by using
  threshold method. We
  ignore time of 2.5
  second, if absolute
  value is clear large
  value of raw heart rate
  and respiration rhythm.
  Thus, we define that it
  is body movement.

                                 7
4 Future work
• Discover similar point about body movement
  during sleep.
• Compare the my results and previous research.
