“…Data are first processed by applying the unscented Kalman filter (UKF), 15 which was implemented similar as in Beravs et al 5 No calibration step is needed to orient the IMUs, as consistent placement is achieved by proper labelling of IMU sensor covers. The evaluated trunk IMU orientation is then expressed relative to the gym IMU coordinate system.…”

Early intervention programs aim at improving cognitive and motor outcomes of preterm infants. Intensive custom-tailored training activities are usually accompanied by assessment procedures, which have shortcomings, such as subjectivity, complex setups, and need for structured environments. A novel sensorized system, called CareToy, was designed to provide stimulation in the form of goal-directed activity training scenarios and motor pattern assessment of main developmental milestones, such as rolling activity, grasping, and postural stability. A group of 28 differently skilled preterm infants were enrolled. Acquired measurement data were analysed with dedicated sensor data processing algorithms, along with clinical evaluation of motor ability. High correlation among technically determined parameters and Alberta Infant Motor Scale values was determined by Pearson correlation coefficients. Due to good accuracy and possibility of single motor skill subfield analysis, results confirm system suitability for motor ability assessment. Statistical analysis of inter-motor ability group and inter-training goal data comparisons demonstrate system's appropriateness for goal-directed activity stimulation. The proposed system has evident potential of being an important contribution to the field of infant motor development assessment, expanding accessibility of early intervention programs and affecting rehabilitation effectiveness of preterm infants.

“…They can be used to capture the camera motion precisely. Based on the captured motion information, navigation [20], orientation determination [4], and human motion tracking [47] can be implemented. Also, deblurring can be performed based on the captured camera motion, in order to remove image blur caused by camera motion [15].…”

Wireless sensor networks present a growing interest in health care applications since they can replace wired devices for detecting signals of physiological origin and continuously monitoring health parameters, offering a reliable and inexpensive solution. In this paper a low cost open architecture wearable sensor network for health care applications is presented. Through this study, an experimental wireless sensor network (WSN) architecture has been built from scratch in order to investigate and present the development procedure and the corresponding capabilities and limitations of such a system. Moreover, technological aspects regarding implementation are also presented.
