Controlling actions in a video game unit

摘要

Sound processing methods and apparatus are provided. A sound capture unit is configured to identify one or more sound sources. The sound capture unit generates data capable of being analyzed to determine a listening zone at which to process sound to the substantial exclusion of sounds outside the listening zone. Sound captured and processed for the listening zone may be used for interactivity with the computer program. The listening zone may be adjusted based on the location of a sound source. One or more listening zones may be pre-calibrated. The apparatus may optionally include an image capture unit configured to capture one or more image frames. The listening zone may be adjusted based on the image. A video game unit may be controlled by generating inertial, optical and/or acoustic signals with a controller and tracking a position and/or orientation of the controller using the inertial, acoustic and/or optical signal.

1. A method for controlling actions in a video game unit having a hand held controller configured for three-dimensional movement, the method comprising configuring a processor for:
receiving an inertial signal from an inertial sensor on the controller; receiving an optical signal generated with one or more light sources on the controller; determining a current position of the controller using the inertial signal, the current position determined using the inertial signal being subject to drift that accumulates over time, the drift being a discrepancy between the determined current position of the controller and an actual position of the controller; receiving one or more images of the light sources obtained with a single camera; separately determining a reference position of the controller from the one or more images; and correcting for the drift that accumulates over time by re-setting the current position of the controller to the reference position separately determined from the one or more images.
