Abstract: Method of dynamically assigning storage locations starts with the processor receiving a signal from a first client device associated with a first user. Processor stores a current location of the first client device in a historical database and determines whether a home location data associated with the first user matches the current location. In response to determining that the home location data associated with the first user does not match the current location, processor determines whether the first user has been associated with the current location at a greater frequency than the home location data based on the historical database. In response to determining that the first user has been associated with the current location at a greater frequency, processor updates the home location data associated with the first user to the current location. Other embodiments are described.

Evaluation of the conditions may contribute to the determination of weights for each of the respective widgets, with the ranking based on the weights. Widgets with the highest rank may be invoked, and selectively displayed on an electronic display. Multiple possible parameter values for the displayed widgets may also be dynamically ranked and selected values applied when invoking the widget.
