Spatial Sound Voice Ad Delivery via Server Processing

The patent introduces a server as an intermediary between the advertisement delivery system and user terminals. The server receives advertisement data including spatial information, processes it, and transmits it to user terminals. This intermediary enables spatial sound directionality without requiring complex modifications to individual user terminals, as the spatial processing is centralized on the server side.

The patent replaces physical spatial sound transmission (which would require multiple speakers positioned at advertisement locations) with electronic/digital spatial sound processing. By using software-based spatial sound operations on the server, the system achieves directionality information preservation without the mechanical complexity of physical speaker arrays at each advertisement location.

The system performs preliminary actions by having users register their preferred locations and directions in advance. The server stores these preferences and uses them for advertisement delivery without requiring continuous real-time monitoring. This approach maintains measurement precision for advertisement targeting while significantly reducing the energy consumption and processing load associated with continuous location tracking.

Instead of continuous monitoring, the system uses periodic action by updating user location and direction information only when needed for advertisement delivery decisions. The server checks registered preferences periodically or trigger-based, rather than maintaining constant real-time monitoring, thereby reducing energy consumption while maintaining sufficient accuracy for effective advertisement delivery.
