In the first experiment, the sensor module was
attached to the thigh of testers to acquire acceleration
signal. Five testers were asked to walk normally,
upstairs, downstairs, stand still and sit down in order
to collect data of five postures. Each posture was then
to be recognized for twenty times, and the statistics of
recognition rate for each tester as well as an average
recognition rate of five testers are calculated. Figures
11-15 depict the experimental results of, respectively,
upstairs, downstairs, walking, standing and sitting.
Table 1 shows the average recognition rate of five
testers.
