AR toy gun is mainly composed of 4 aspects: Bluetooth chip, motherboard, shell, AR game. AR game manufacturers integrate Bluetooth chips and motherboards to package them into an overall AR game gun solution. The main function of the Bluetooth chip is to connect the mobile phone and the toy gun via Bluetooth, which is used to pull the trigger of the toy gun and perform virtual operations such as shooting on the mobile phone screen. The Bluetooth chip is the main key. It needs good compatibility and can be compatible with Bluetooth 3.0 mobile phones and Bluetooth 4.0 mobile phones; the delay needs to be about 10 milliseconds; the connection current, working current, standby current and shutdown current should be small, so that the power consumption is small.
The AR gun has the shape of a pistol or assault rifle or the appearance of a game handle; compared with the original ordinary game handle or touch screen, the game experience and senses are greatly improved.
The usual AR gun has one button or multiple buttons, or multiple joysticks. Its functions include trigger button, reload button, weapon change button, etc., forward and backward, translation and rotation angle of view, etc. These operations can fully meet the operations of almost all first-view games, especially action/shooting games.
The AR gun is connected to the mobile phone APP via Bluetooth. This connection method is simple, compatible and quick to respond.
With the help of flexible Bluetooth chip architecture, Juwei provides a variety of flexible low-cost AR gun solutions.
