The one or more hardware processors can modify a value of the plurality of timers based on an amount of time the patient is oriented in the plurality of orientations. The one or more hardware processors can generate an interactive graphical user interface on the display screen. The user interface can include a graphic for illustrating an orientation history of the patient. The one or more hardware processors can modify an appearance of the graphic based upon the values the plurality of timers. ## Claims ### Claim 1 A system for monitoring an orientation of a patient to reduce a health risk of the patient, the system comprising: one or more hardware processors configured to: receive output signals from a sensor attached to the patient;
