Abstract
Disclosed herein are methods and systems that involve monitoring presence of items based on context. An exemplary method involves: (i) determining a context for a given user; (ii) determining a proximity framework between a monitoring device and one or more items, based on the determined context, wherein the proximity framework comprises (a) one or more proximity requirements, each proximity requirement indicating a required proximity between the monitoring device and at least one of the items and (b) a notification process corresponding to each proximity requirement; (iii) monitoring proximity of each of the items relative to the monitoring device, based on a presence signal from each of the items, in order to determine when one of the proximity requirements is not met; and (iv) responsive to determining that one of the proximity requirements is not met, initiating the corresponding notification process.
