Activity recognition invariant to sensor orientation with wearable motion sensors
(MDPI AG, 2017)Most activity recognition studies that employ wearable sensors assume that the sensors are attached at pre-determined positions and orientations that do not change over time. Since this is not the case in practice, it is ... -
Breathing detection based on the topological features of IR sensor and accelerometer signals
(IEEE Computer Society, 2017)This paper describes a non-contact breathing detection system using a pyro-electric infrared (PIR) sensor and an accelerometer. The multi-sensor system can be used to detect the respiratory disorders. A PIR sensor is placed ... -
A comparative study of classification methods for fall detection
(IEEE Computer Society, 2014)A comparative study of various fall detection algorithms based upon measurements of a wearable tri-axial accelerometer unit is presented in this paper. Least squares support vector machine, neural network and rule-based ... -
Detection and evaluation of physical therapy exercises by dynamic time warping using wearable motion sensor units
(Springer Verlag, 2014)We develop an autonomous system that detects and evaluates physical therapy exercises using wearable motion sensors. We propose an algorithm that detects all the occurrences of one or more template signals (representing ... -
Detection and evaluation of physical therapy exercises from wearable motion sensor signals by dynamic time warping
(IEEE Computer Society, 2014)We develop an autonomous system to detect and evaluate physical therapy exercises using wearable motion sensor units. We propose an algorithm based on the dynamic time warping (DTW) dissimilarity measure to detect the ... -

(Institution of Engineering and Technology, 2016)Deterministic error modelling, calibration and model parameter estimation of consumer-grade accelerometers is considered and improvement to the traditionally used measurement model is proposed. Calibration experiments on ... -
Inertial navigation systems for mobile robots
(Institute of Electrical and Electronics Engineers, 1995-06)A low-cost solid-state inertial navigation system (INS) for mobile robotics applications is described. Error models for the inertial sensors are generated and included in an Extended Kalman Filter (EKF) for estimating ... -
Investigation of Sensor Placement for Accurate Fall Detection
(Springer Verlag, 2017)Fall detection is typically based on temporal and spectral analysis of multi-dimensional signals acquired from wearable sensors such as tri-axial accelerometers and gyroscopes which are attached at several parts of the ... -
Leg motion classification with artificial neural networks using wavelet-based features of gyroscope signals
(2011)We extract the informative features of gyroscope signals using the discrete wavelet transform (DWT) decomposition and provide them as input to multi-layer feed-forward artificial neural networks (ANNs) for leg motion ... -
Recognizing daily and sports activities in two open source machine learning environments using body-worn sensor units
(Oxford University Press, 2014-11)This study provides a comparative assessment on the different techniques of classifying human activities performed while wearing inertial and magnetic sensor units on the chest, arms and legs. The gyroscope, accelerometer ...
