System and Method for Exploring 3D Scenes by Pointing at a Reference Object

摘要

The system and method are described for enhancing location-based services by enabling spatial database systems to respond to or answer spatial queries that use a reference object to identify objects or features of interest in environmental scene before a system user. The system and method present invention enhances pointing technology by permitting system users to use queries to identify objects or features within the system user's field of view by pointing at the reference object or feature, and linking it to the object of interest by using spatial prepositions.
