1. A method for monitoring an orientation of a person on a support surface of a motion detection system, the method comprising:
receiving, via an input device of the motion detection system, restricted position input defining at least one person-specific restricted body position selected from a plurality of body positions, wherein different regions of the person's body are pressurized by the support surface in different ones of the plurality of body positions;
displaying, via a display device of the motion detection system, the at least one person-specific restricted body position selected via the input device;
generating, by at least one sensor of a wearable sensor device, sensor data associated with an orientation of the person on the support surface;
monitoring the orientation of the person on the support surface over time based on the sensor data;
determining, by a processor of the motion detection system, based on the monitored orientation of the person on the support surface, a turn from a first body position to a second body position;
determining, by the processor of the motion detection system, whether the second body position corresponds with the at least one person-specific restricted body position defined by the received restricted position input;
if the second body position corresponds with the at least one person-specific restricted body position, automatically displaying, via the display device, a restricted position alert and a visual indication of time spent in the second body position; and
if the second body position does not correspond with the at least one person-specific restricted body position:
monitoring, by the motion detection system, a time spent in the second body position;
automatically comparing, by the motion detection system, the monitored time spent in the second body position with a defined threshold time limit for the second body position, wherein the motion detection system dynamically adjusts the defined threshold time limit for the second body position based on a duration of a prior time spent out of the second body position; and
automatically outputting, by an audible or visual output device of the motion detection system, an audible or visual turn alert based on the comparison of the monitored time spent in the second body position with the defined threshold time limit for the second body position, the audible or visual turn alert indicating a needed turn of the person relative to the support surface.
