A system for automated monitoring of a person's position, comprising: a wearable sensor device configured to be secured to or otherwise worn by the person; at least one multi-axis accelerometer provided in the wearable sensor device and configured to generate sensor data regarding an orientation of the person; a display device; and a processor (125, 310) configured to: monitor the orientation of the person over time based on the sensor data generated by the at least one sensor; manage an accumulated time counter associated with indicating time spent by the person in a particular orientation of the person, including: increasing the accumulated time counter at a defined pressurization rate while the person is positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; and decreasing the accumulated time counter at a defined depressurization rate while the person is not positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; and characterized in that the processor is further configured to: dynamically adjust at least one of the pressurization rate for the accumulated time counter and the depressurization rate for the accumulated time counter; compare the accumulated time counter to a pressurization threshold to determine a remaining time until a next turn, as defined by a turn protocol for the person; and control the display device to visually indicate the remaining time until the next turn based on the comparison of the accumulated time counter to the pressurization threshold. a wearable sensor device configured to be secured to or otherwise worn by the person; at least one multi-axis accelerometer provided in the wearable sensor device and configured to generate sensor data regarding an orientation of the person; a display device; and a processor (125, 310) configured to: monitor the orientation of the person over time based on the sensor data generated by the at least one sensor; manage an accumulated time counter associated with indicating time spent by the person in a particular orientation of the person, including: increasing the accumulated time counter at a defined pressurization rate while the person is positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; and decreasing the accumulated time counter at a defined depressurization rate while the person is not positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; monitor the orientation of the person over time based on the sensor data generated by the at least one sensor; manage an accumulated time counter associated with indicating time spent by the person in a particular orientation of the person, including: increasing the accumulated time counter at a defined pressurization rate while the person is positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; and decreasing the accumulated time counter at a defined depressurization rate while the person is not positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; increasing the accumulated time counter at a defined pressurization rate while the person is positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; and decreasing the accumulated time counter at a defined depressurization rate while the person is not positioned in the particular orientation, as determined based on the sensor-based monitored orientation of the person; and characterized in that the processor is further configured to: dynamically adjust at least one of the pressurization rate for the accumulated time counter and the depressurization rate for the accumulated time counter; compare the accumulated time counter to a pressurization threshold to determine a remaining time until a next turn, as defined by a turn protocol for the person; and control the display device to visually indicate the remaining time until the next turn based on the comparison of the accumulated time counter to the pressurization threshold. dynamically adjust at least one of the pressurization rate for the accumulated time counter and the depressurization rate for the accumulated time counter; compare the accumulated time counter to a pressurization threshold to determine a remaining time until a next turn, as defined by a turn protocol for the person; and control the display device to visually indicate the remaining time until the next turn based on the comparison of the accumulated time counter to the pressurization threshold.
