US 8,804,093 B2 · Systems and methods for theater seat movement

Abstract

Systems and methods for providing movement to seating including theater seating generate complex motion responses in the seating by automatically analyzing an audio component of media being consumed for one or more aspects of the audio information contained in the audio component at certain frequencies or frequency ranges. The aspects analyzed include aspects relating to frequencies and frequency ranges substantially higher than the low-frequency signals used to drive motion of theater seating. From the analysis of the audio aspects contained in the audio component, a plurality of independent low-frequency output signals is generated. The plurality of independent low-frequency output signals is directed to a plurality of individual actuators incorporated into different locations in a seat to provide sensations of motion at different locations of the seat, such as at a seat location, at a lower back location, and at an upper back location.

Dependent claims

A system for providing a motion-enhanced experience to consumption of media containing audio information, the system comprising:

a seat having a plurality of motion-generating assemblies incorporated therein at different locations of the seat;
and
a signal processor module communicatively connected to the motion-generating assemblies, the signal processor module being configured to receive audio information from an audio source and to process the audio information into a plurality of output signals, each output signal comprising primarily low-frequency signal information generated by the signal processor module to drive one of motion and output simulating motion, and each output signal being simultaneously directed to one of the motion-generating assemblies, the output signals differing from the audio information received from the audio source;
wherein the signal processor module comprises a digital signal processor that is configured to devalue or suppress audio information carried on an input channel carrying a majority of dialog contained in the audio information from the audio source to minimize or eliminate motion at the motion-generating assemblies caused by dialog.
