Abstract: An adapter is disclosed to include a casing holding a webcam and a microphone for picking up images and voices from the display and speaker of a first electronic apparatus, and an A/V (audio/video) transmitting interface connected to the AV (audio/video) receiving interface of a second electronic apparatus and controlled by a control circuit in the casing to transmit audio and video signals obtained from the first electronic apparatus to the AV (audio/video) receiving interface of the second electronic apparatus for output through the display and speaker of the second electronic apparatus.

Abstract: Disclosed is a game control system, which includes a main unit, and a controller for controlling the main unit to run a game software and having a camera mounted in the front side of the housing thereof and electrically connected to the circuit board inside the housing for picking up images and sending obtained images to the main unit for comparison to calculate the amount of movement of the controller relative to the main unit. Incorporating the camera into the inside of the housing of the controller saves manufacturing tools and packing materials, reduces system size and delivery cost.

Abstract: A photographic pointer positioning system includes a photographic pointing device connectable to a game machine main unit (system main unit) and a display screen through a communication interface thereof. The photographic pointing device uses a camera controlled by a control circuit to pick up the image of the display area of the display screen, an image processing circuit to process of the image signal, at least one reference sign to facilitate the processing of the image signal by the image processing circuit, a computing unit to calculate the coordinate value of the aiming point of the camera at the display screen subject to the data of the image signal obtained from the image processing circuit, and buttons for operation by user.

Abstract: A wireless controller for a video game system is disclosed. The wireless controller for a video game player comprises a wireless receiver and a sound transformer that are connected with a first memory chip receiver of the video game player. The built-in microphone and amplifier of the wireless receiver allows the user to use the wireless controller to transmit signals and communicate with the wireless receiver wirelessly. Thus without using headset with microphone, the user can control the wireless controller and also communicate with the other online player within an effective transmission range.

Abstract: A sound device of a video game system is provided. The video game system has at least a video game player having a first control circuit and a first communication interface and second communication interface. The sound device has a game controller, a third communication interface and a second control circuit. The game controller is connected to the first communication interface, the third communication interface is connected to the second communication interface and the second control circuit is connected to the third communication interface, a speaker, a microphone, a volume regulator and a microphone switch. A signal generated by operating the volume regulator and the microphone switch can be used by the second control circuit to control a volume of the speaker and to turn on/off the microphone, and players can communicate with each other via the speaker and the microphone without wearing an earphone and microphone while playing online video game.

Abstract: A video game system having sound device is provided. The video game system comprises a sound adaptor and a sound device connected to a first memory card slot and a second memory card slot of a game controller of the video game player such that a user can communicate with other users through a built-in microphone and speaker of the sound device within a valid range via wireless controller. Therefore, a user can directly execute a game by wirelessly controlling the game controller without wearing wired earphone and microphone.
