We can also see the sparsity of the sensor readings and the irregular time intervals between sensor readings during activity performance, noted by the varying time intervals between markers on the plot. (b) shows RSSI values for the 3 antennas used in the hospital deployment, we can see the changes in RSSI values across activity boundaries, most notable change is that of antenna 3 (in green) when the patient moves from sitting on chair to ambulating.</p> 2017-10-09 17:32:00 chair exits activity score function chair exit recognition RFID chair exit recognition process wearable sensor system movement monitoring sensor system pilot study multifactor sensor acceptance model
