Device and method for monitoring the presence of items and issuing an alert if an item is not detected

A system comprising:

• a mobile device and one or more storage devices storing instructions that are operable, when executed by the mobile device, to cause the mobile device to perform operations comprising:
• determining, by the mobile device, a first context of the mobile device;
• determining, while the mobile device remains associated with the first context, that one or more items are located within a predetermined distance from the mobile device;
• generating, by the mobile device, a data record that indicates the first context and the determined one or more items;
• determining, by the mobile device and using multiple data records (i) including the data record, (ii) including data records from historical data, and (iii) that each indicate the first context and each of the one or more items, that each of the one or more items are determined to be within the predetermined distance from the mobile device at least a threshold amount when the mobile device determines the first context;
• and
• identifying, by the mobile device using the multiple data records, a proximity framework for the first context that indicates the one or more items and a particular notification.

A non-transitory computer-readable medium storing software comprising instructions executable by a mobile device which, upon such execution, cause the mobile device to perform operations comprising:

• determining, by the mobile device, a first context of the mobile device;
• determining, while the mobile device remains associated with the first context, that one or more items are located within a predetermined distance from the mobile device;
• generating, by the mobile device, a data record that indicates the first context and the determined one or more items;
• determining, by the mobile device and using multiple data records (i) including the data record, (ii) including data records from historical data, and (iii) that each indicate the first context and each of the one or more items, that each of the one or more items are determined to be within the predetermined distance from the mobile device at least a threshold amount when the mobile device determines the first context;
• and
• identifying, by the mobile device using the multiple data records, a proximity framework for the first context that indicates the one or more items and a particular notification.
