Abstract

A tracking device for use in obtaining information for controlling an execution of a game program by a processor for enabling an interactive game to be played by a user and related apparatus are disclosed.

Claims

1. A tracking device for use in obtaining information for controlling an execution of a game program by a processor for enabling an interactive game to be played by a user, comprising:

a movable body;

a sound emitter operable to emit a sound attached to the body; and

a processor operable to execute the game program for enabling the interactive game to be played by the user, the apparatus further comprising an acoustic transducer, wherein the acoustic transducer includes a microphone array having two or more microphones, each microphone being coupled to a plurality of filters, the filters being configured to filter input signals corresponding to sounds detected by the microphones thereby generating a filtered output, wherein the processor is configured to;

pre-calibrate plurality of sets of filter parameters for the plurality of filters to determine a corresponding plurality of pre-calibrated listening zones, wherein each set of filter parameters is selected to detect portions of the input signals corresponding to sounds originating within a given listening zone and filter out sounds originating outside the given listening zone; and

select a particular pre-calibrated listening zone at a runtime by applying to the plurality of filters sets of filter parameters corresponding to two or more different pre-calibrated listening zones;

determine a value of an attenuation of the input signals for the two or more different pre-calibrated listening zones;

select a particular zone of the two or more different pre-calibrated listening zones for which the attenuation is closest to an optimum value; and

apply the filter parameters for the particular zone to the plurality of filters;

wherein the processor is operable to register input to the game program based on acoustic information produced by the acoustic transducer in response to a sound emitted by the sound emitter.

2. The tracking device as claimed in claim 1, wherein the sound emitter includes at least one of a speaker, a buzzer, a horn or a pipe.

3. The apparatus as claimed in claim 1, wherein the processor is operable to register the input when the acoustic information satisfies a predetermined criterion.

4. The apparatus as claimed in claim 3, wherein the sound emitter is operable to emit a sound specific to a particular user associated with the tracking device and the processor is operable to register input specific to the particular user when the specific sound is emitted.

5. The apparatus as claimed in claim 3 or 4, wherein the predetermined criterion includes at least one criterion selected from the group consisting of pitch, audio pulse frequency, audio pulse shape, audio pulse duty cycle, beat frequency, or spectral signature including a spectral content characteristic of a distinctive sound.

6. The tracking device as claimed in claim 1, further comprising a communications interface operable to conduct digital communications with at least one of the processor, a game controller or both the processor and the game controller.

7. The tracking device as claimed in claim 6, wherein the communications interface includes a universal asynchronous receiver transmitter (“

UART”

).

8. The tracking device as claimed in claim 7, wherein the UART is operable to perform at least one of receiving a control signal for controlling an operation of the tracking device, or for transmitting a signal from the tracking device for communication with another device.

9. The tracking device as claimed in claim 6 or 7, wherein the communications interface includes a universal serial bus (“

USB”

) controller.

10. The tracking device as claimed in claim 9, wherein the USB controller is operable to perform at least one of receiving a control signal for controlling an operation of the tracking device, or for transmitting a signal from the tracking device for communication with another device.

11. The tracking device as claimed in claim 1, wherein the body is mountable to a game controller, the game controller including a game controller body and at least one input device assembled with the game controller body, the input device manipulable by a user to register an input from the user.

12. An apparatus including the tracking device and the game controller as claimed in claim 6.

13. The tracking device as claimed in claim 1, wherein the body of the tracking device is mountable to the user'"'"'s body.
