Wristband-placed physical activity monitors, as a convenient means for counting walking steps, assessing movement, and estimating energy expenditure, are widely used in daily life. There are many consumer-based wristband monitors on the market, but there is not an unified method to compare their performance. In this paper, we designed a series of experiments testing step counting performance under...
This study performed a concurrent comparison of two walking speed estimation methods using shank- and foot-mounted inertial measurement units (IMUs). Based on the cyclic gait pattern of the stance leg during walking, data was segmented into a series of individual stride cycles. The angular velocity and linear accelerations of the shank and foot over each of these cycles were then integrated to determine...
In this study we investigated the feasibility and performance of estimating walking speed under different combinations of step length and step frequency using a shank-mounted inertial measurement unit (IMU). The estimation algorithm is based on the fact that the walking is a cyclical motion with a distinguishable pattern and an inverted pendulum-like behavior. To evaluate its performance under different...
