Abstract: Instrumentalities to receive, with respect to a structure, an indication of two distinct problem types that specifies unused space(s), thereby forming a problem space, and responsively presenting second unused space(s) to a mobile device without the specified unused space(s). The second unused space(s) are presented in order, shortest distance to longest distance. Next, instrumentalities present a second mobile device with unused spaces that exclude the specified unused space(s). Order remains, shortest distance to longest distance, with respect to a current user location, which may be fixed by reference to a location of at least one access point to each respective unused space. The at least one access point can be one of several access points that serve the structure.

Abstract: Instrumentalities are effective to at least provide a user interface to a mobile device of the user for finding an unused space, among a plurality of spaces, according to a user-selected criteria, wherein the user interface is transmitted via a wireless protocol agreed during the wireless handshake; and in response, presenting the mobile device with first unused spaces meeting the user-selected criteria. Further, an access point may receive a problem space indication from the user concerning at least one of the unused spaces which associates a problem to the at least one of the unused spaces, thereby forming a problem space, and in response, second presenting a second at least one unused space to the mobile device without the problem space, wherein the second unused spaces are presented in order of nearness to a current user location.
