Abstract
An apparatus comprising circuitry configured to generate one or more focused sound sources as virtual loudspeakers of an announcement system.
Claims19
A public announcement system comprising:
- circuitry configured to
- calculate, in real time, a plurality of successive and different trajectories that represent recommended paths for a person to take to arrive at a predefined destination of a predefined space from respective current locations of the person as the person moves within the predefined space,
- generate, in real time, for the predefined space, one or more focused sound sources as virtual loudspeakers of the public announcement system whose position changes dynamically in correspondence with the plurality of trajectories such that the one or more focused sound sources as the virtual loudspeakers are always on the respective trajectories and between the person and the predefined destination of the predefined space until the person reaches the predefined destination, for any orientation and direction of movement of the person in the predefined space, and
- output, in real time, for the predefined space, the one or more focused sound sources as the virtual loudspeakers of the public announcement system,
- wherein the circuitry is remote from the person.
2 more elements
A method comprising:
- calculating, in real time, using processing circuitry of an announcement system, a plurality of successive and different trajectories that represent recommended paths for a person to take to arrive at a predefined destination of a predefined space from respective current locations of the person as the person moves within the predefined space;
- generating, in real time, using the processing circuitry of the announcement system, for the predefined space, one or more focused sound sources as virtual loudspeakers of the announcement system whose position changes dynamically in correspondence with the plurality of trajectories such that the one or more focused sound sources as the virtual loudspeakers are always on the respective trajectories and between the person and the predefined destination of the predefined space until the person reaches the predefined destination, for any orientation and direction of movement of the person in the predefined space;
- and
- outputting, in real time, using the processing circuitry of the announcement system for the predefined space, the one or more focused sound sources as the virtual loudspeakers of the announcement system,
- wherein the processing circuitry is remote from the person.
2 more elements
A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by one or more processors of an announcement system, cause the one or more processors to perform a method comprising:
- calculating a plurality of successive and different trajectories that represent recommended paths for a person to take to arrive at a predefined destination of a predefined space from respective current locations of the person as the person moves within the predefined space;
- and
- generating for the predefined space one or more focused sound sources as virtual loudspeakers of the announcement system whose position changes dynamically in correspondence with the plurality of trajectories such that the one or more focused sound sources as the virtual loudspeakers are always on the respective trajectories and between the person and the predefined destination of the predefined space until the person reaches the predefined destination, for any orientation and direction of movement of the person in the predefined space,
- wherein said generating includes generating, at a same time, for each of a plurality of persons in the predefined space, including said person, a person-focused sound source as said one or more focused sound sources, and
- wherein the one or more processors of the announcement system are remote from the plurality of persons.
