A Study of Walking Speed Measurement for Elderly Health Assessment Using UltraHigh-frequency Radio-Frequency Identification Tags
Highlights
A Study of Walking Speed Measurement for Elderly Health AssessmentTwo antennas at a certain distance apart are used to measure human walking speed by reading the time difference of the radio frequency identification (RFID) tag
The health of the elderly is a hotspot in recent scientific research
It can be seen that correlation time difference method using the Phat processor and smoothed coherence transform (SCOT) weighting is more accurate than the maximum time difference method which combines partitioned Gaussian fitting with Kalman filter
Summary
Two antennas at a certain distance apart are used to measure human walking speed by reading the time difference of the RFID tag. The experimental results show that the precise measurement of the walking speed can be realized by employing the maximum time difference method and correlation time difference method. The former combines partitioned Gaussian fitting with Kalman filter, and the latter uses the Phat processor along with smoothed coherence transform (SCOT) weighting. These methods could be used to measure the daily walking speed of elderly individuals in senior health centers
