LBS-based applications heavily rely on location constraints to select information to meet users' demands. Many decisions in real life, however, must also consider the influence of temporal constraints. This research intends to develop a location-aware push service that provides useful messages of campus events to students by taking both spatial and temporal perspectives into consideration. Temporal information is additionally included as an essential type of constraint to determine if a message would be pushed to users. This implies that the offered information not only changes with the movement of users, but also changes as times go by. The prototype of Location-Aware Pushing Service (LAPS) is designed to continuously and automatically sending useful information from the campus database to students according to their changing status. As the number of students using smart phones continuously increases, the proposed mechanism can be further enhanced to enable schools to instantly select and effectively distribute valuable information to enrich students' campus lives on an individual student basis.
