We in this paper introduce a real-time human arm movement tracking system that can be used to aid the rehabilitation of stroke patients. A 3-axis inertial sensor is used to capture arm movements in 3-D space and in real time. The tracking algorithm is based on a kinematical model that just

Abstract—ARMA-modeling the inertial sensor’s colored noise must determine the AR parameters, the MA parameters, as well as the variance of the measurement white noise when the order of the ARMA model is estimated. Due to the existence of the MA items, the Yule-Walker equation constructed

A calibration technique for a redundant inertial measurement unit (IMU) containing low-grade inertial sensors is proposed. In order to calibrate a redundant IMU that can detect and isolate faulty sensors, the fundamental coordinate frames in the IMU are defined and the IMU error is modeled based

Abstract — This paper proposes an approach to calibrate off-the-shelf cameras and inertial sensors to have a useful integrated system to be used in static and dynamic situations. The rotation between the camera and the inertial sensor can be estimated, when calibrating the camera, by having both

Abstract—this paper presents our results on the application of various inertial sensors for motion analysis. After the introduction of different sensor types (accelerometer, gyroscope, magnetic field sensor), we discuss the possible data collection and transfer techniques using embedded signal

from electromagnetic disturbances, noise and multipath problems. Mechanical systems have physical constraints that limit the natural body movement. Recently, the availability of low-cost wearable inertial sensors containing ac-celerometers, gyroscopes, and magnetometers has provided an alternative

Abstract—Inertial sensors, like accelerometers and gyroscopes, are rarely used by themselves to measure displacement. Accuracy of inertial sensors is greatly handicapped by the notorious integration drift, which arises due to numerical integration of the sensors zero bias error. A solution
