The system comprises a location tracking sub-system, communication devices and a context-aware location engine. The context-aware location engine is configured to receive from the location tracking sub-system a plurality of initial location estimations for the communication devices and generate a plurality of filtered location estimates for the communication devices. ## Claims ### Claim 1 A system for improving tracking indoor or outdoor object movement using workflow context information, the system comprising: a location tracking system comprising a plurality of sensors located in a facility for real-time location tracking of persons and/or objects; a plurality of communication devices, each of the plurality of communication devices associated with an object or a person, each of the plurality of communication devices configured to transmit a signal to at least one of the plurality of sensors; and a context-aware location engine in communication with the location tracking system, the context-aware location engine configured to receive from the location tracking system a plurality of initial location estimations for the plurality of communication devices and the context aware location engine configured to generate a plurality of filtered location estimates for the plurality of communication devices based on at least one of a standard workflow, specific usage information for a plurality of objects in the facility, location classification, and information from a plurality of communication interactions for interactions between the plurality of communication devices. ### Claim 2 (depends on 1) The system according to claim 1 wherein the context aware location engine comprises the standard workflow that is known a priori. ### Claim 3 (depends on 1) The system according to claim 1 wherein the context aware location engine comprises the standard workflow that is customary. ### Claim 4 (depends on 3) The system according to claim 3 wherein the workflow is at least one of a series of locations, a series of states, a series of dwell times, a series of interactions, a series of milestones, or a series of detected events. ### Claim 5 (depends on 4) The system according to claim 4 wherein the series of milestones is at least one of a physician call, an EMS call, an arrival/sign-in, a nurse saw, a doctor saw, an entered ED, a departed ED, a bed request, a bed check, a bed ready, a fully registered, a triaged, a quick registered, a dispo ordered, and a floor report. ### Claim 6 (depends on 4) The system according to claim 4 wherein the series of milestones is at least one of case created, a check-in, a ready for pre-op, a pre-op declined, a pre-op accepted, an arrived pre-op room, a ready for pre-op nurse, a patient prepped, a left pre-op, an inpatient ready, an ED ready, an arrived OR, a procedure start, a procedure end, a ready for PACU, a ready for ICU, a ready for post-op, a PACU decline, a post-op declined, a PACU accepted, a post-op accepts OR and a departed OR. ### Claim 7 (depends on 1) The system according to claim 1 wherein the role of each object associated with each of the plurality of communication devices is maintained and tracked by the context-aware location engine. ### Claim 8 (depends on 1) The system according to claim 1 wherein the object is selected from the group of a patient, a nurse, a physician, housekeeping member, a technician, a transport, a room, a fix location asset, and a moveable asset. ### Claim 9 (depends on 8) The system according to claim 8 wherein the context-aware location engine is configured to track a location history and a plurality of workflow stages of each the objects being tracked. ### Claim 10 (depends on 4) The system according to claim 4 wherein the facility is a hospital and the plurality of workflow stages of patient under tracking comprises at least one of a patient arrival stage, a patient in preparation for a medical procedure, a patient in a medical procedure stage, a patient in post-medical procedure stage, and a patient departure. ### Claim 11 (depends on 1) The system according to claim 1 wherein the context-aware location engine is configured to maintain and track workflow specific usage information about each of a plurality of locations in the facility. ### Claim 12 (depends on 11) The system according to claim 11 wherein the facility is a hospital and the plurality of workflow specific usage of the locations comprise at least one of a patient room, a nurse station, a hallway, a storage room, a clean utility room, a dirty utility room, a hallway, an exit, a stairway, a restroom, and an office. ### Claim 13 (depends on 1) The system according to claim 1 wherein the context-aware location engine is configured to maintain and track the real-time user input information of each the objects or persons being tracked. ### Claim 14 (depends on 13) The system according to claim 13 wherein the facility is a hospital and the real-time user input information comprises at least one of staff marking a patient arrival and staff assigning a room to a patient. ### Claim 15 (depends on 1) The system according to claim 1 wherein the context-aware location engine is configured to maintain and track a plurality of real-time interactions between moveable and fixed objects under tracking. ### Claim 16 (depends on 15) The system according to claim 15 wherein the facility is a hospital and plurality of real-time interactions between moveable and fixed objects under tracking comprises at least one of staff or patient interactions with fixed known location objects. ### Claim 17 (depends on 1) The system according to claim 1 wherein the context-aware location engine is configured to maintain and track a plurality of real-time interactions between moveable and movable objects under tracking. ### Claim 18 (depends on 17) The system according to claim 17 wherein the facility is a hospital and plurality of real-time interactions between moveable and moveable objects under tracking comprises at least staff and patient interactions.
