Abstract:
1. A computer-implemented method comprising: generating and storing historical context data, at each of a plurality of instances, comprising: determining a current context for the monitoring device; retrieving the historical context data; selecting, from among multiple proximity frameworks, a particular proximity framework between the monitoring device and two or more items from the plurality of items using the historical context data, based on the determined current context, wherein each proximity framework indicates (a) two or more different proximity requirements, each proximity requirement indicating a required proximity between the monitoring device and at least one of the two or more items and (b) a different notification process corresponding to each proximity requirement, and wherein, for a particular item, two different proximity frameworks indicate a different proximity requirement or a different notification process; monitoring a proximity of each of the two or more items relative to the monitoring device, based on a presence signal from each of the two or more items, in order to determine when one of the proximity requirements of the particular proximity framework is not met; and responsive to determining that one of the proximity requirements is not met, initiating the corresponding notification process.
