1. A method of operating a medication delivery system comprising a fluid pump mechanism and at least one controller that regulates operation of the fluid pump mechanism to deliver medication from the medication delivery system, the method comprising:
operating the medication delivery system in a first mode of operation to automatically deliver the medication to a user in accordance with a therapy control algorithm;
receiving body movement information generated at least in part from gesture data for the user, the gesture data provided by a gesture-based physical behavior detection system;
searching a movement correlation database to find a body motion or a pattern of body motions correlated with the body movement information, wherein the body motion or the pattern of body motion associates with involuntary movement of body muscles;
identifying a physiological characteristic response of the user, the physiological characteristic response correlated with the body motion or the pattern of body motions found by the searching; and
operating the medication delivery system in a second mode of operation to automatically deliver the medication to the user in accordance with a movement-correlated therapy control algorithm, based at least in part on the identified physiological characteristic response.
 
9. A medication delivery system comprising:
a fluid pump mechanism;
at least one controller that regulates operation of the fluid pump mechanism to deliver insulin from the medication delivery system; and
at least one memory element associated with the at least one controller, the at least one memory element storing processor-executable instructions configurable to be executed by the at least one controller to perform a method of controlling operation of the medication delivery system, the method comprising:
operating the medication delivery system in a first mode of operation to automatically deliver the insulin to a user in accordance with a therapy control algorithm;
receiving body movement information generated at least in part from gesture data for the user, the gesture data provided by a gesture-based physical behavior detection system;
searching a movement correlation database to find a body motion or a pattern of body motions correlated with the body movement information, wherein the body motion or the pattern of body motion associates with involuntary movement of body muscles;
identifying a glucose response of the user, the glucose response correlated with the body motion or the pattern of body motions found by the searching; and
operating the medication delivery system in a second mode of operation to automatically deliver the insulin to the user in accordance with a movement-correlated therapy control algorithm, based at least in part on the identified glucose response.
 
16. A system comprising:
an insulin infusion device that regulates delivery of insulin to a user;
a gesture-based physical behavior detection system configured to generate gesture data for the user, and configured to communicate the gesture data; and
at least one controller that controls operation of the insulin infusion device, the at least one controller configured to:
operate the insulin infusion device in a first mode of operation to automatically deliver the insulin to the user in accordance with a therapy control algorithm;
process body movement information generated at least in part from gesture data provided by the gesture-based physical behavior detection system;
search a movement correlation database to find a body motion or a pattern of body motions correlated with the body movement information, wherein the body motion or the pattern of body motion associates with involuntary movement of body muscles;
identify a glucose response of the user, the glucose response correlated with the body motion of the pattern of body motions found by the searching; and
operate the insulin infusion device in a second mode of operation to automatically deliver the insulin to the user in accordance with a movement-correlated therapy control algorithm, based at least in part on the identified glucose response.
