Abstract
The system produces movements in a home entertainment chair. It has a motor controller and a plurality of movement generator units for generating small amplitude and low frequency movements in the viewers chair according to desired effects. A synchronization is achieved using an audio/video stream.
Claims16
An apparatus for generating motion effects for at least one actuator using an audio/video source stream signal, said apparatus comprising:
- a track analyzer receiving said stream signal and performing a track analysis of said stream signal to produce a time variable characteristic signal;
- an effect generator receiving said time variable characteristic signal and generating at least one effect according to at least one rule;
- and
- a movement generator receiving said at least one effect and compiling said at least one effect to provide a single signal to each of said at least one actuator.
A method for generating motion effects using at least one actuator with respect to an audio/video source, said method comprising the steps of:
- receiving a signal from said audio/video source;
- analyzing said signal to generate a second signal;
- using said second signal and rule to provide at least one effect;
- and
- compiling said second signal in order to provide a third signal to each of said at least one actuator according to said at least one effect.
A method of providing haptic and motion sensations to at least one viewer in a simulator environment, the method comprising the steps of:
- providing at least three actuators supporting at least one seat for said viewer, said actuators being adapted to move said seat and said viewer with small amplitudes at a frequency representing mechanical vibration;
- generating a vibration signal representing a level of vibration in said seat corresponding to a level of vibration associated with a virtual environment at each point in time;
- generating a visual cue signal representing a reciprocal visual cue movement in said seat corresponding to motion in said virtual environment at each point in time;
- converting said vibration signal into a first actuator position value for all of said actuators;
- converting said visual cue signal into second actuator position values for said actuators for causing at least a tilt in said seat;
- combining said first position value and said second position values to obtain an activation control value for each of said actuators;
- and
- supplying said control value to said actuators in real time.
