DETAILED DESCRIPTION

[0019] As Figures 1-6 shown, the utility model embodiment provides a handheld XR head-mounted control host with 3D interaction function, including upper shell 21, the back of upper shell 21 is clamped with lower shell 22, the bottom of upper shell 21 and lower shell 22 is equipped with hanging rope hole 27, the whole periphery annular heat dissipation hole 23 of joystick 1, both increase product appearance, with equipment heat dissipation function simultaneously, the outside of upper shell 21 is provided with joystick 1, return key 2, menu key 3, custom key 4 and trigger key 5, the back of lower shell 22 is provided with ray control key 6, the inside of upper shell 21 and lower shell 22 is provided with sheet metal fixing support 19, the side of sheet metal fixing support 19 is provided with volume + 7, volume - 8 and power on key 9, the surface of sheet metal fixing support 19 is provided with battery support 15, the surface of battery support 15 is installed with battery 14, the surface of sheet metal fixing support 19 is installed with main circuit board 16, the top of sheet metal fixing support 19 is installed with sub-circuit board 20, the front of upper shell 21 is provided with system indicator 10, the left side of upper shell 21 and lower shell 22 is provided with power indicator 11, charging debugging interface 12 and noise reduction microphone 26, the back of lower shell 22 is provided with loudspeaker 17, the inside of lower shell 22 is installed with vibration motor 18, the bottom of upper shell 21 is provided with recording microphone 25, the back of custom key 4 is provided with flexible circuit board 24, main circuit board 16 is connected with audio and video output interface 13.

[0020] This scheme is first used in AR split host with joystick interaction, because the size of joystick is higher, the mobile phone needs to keep the overall size small and comfortable to hold, and the thickness is relatively thin, so the joystick 1 is arranged separately from the mainboard, so that a small circuit board (sub-board) is additionally made, the two circuit boards are connected through FPC, the battery 14 is arranged separately from the sub-board, and the thickness of the battery 14 is maximized under the condition that the size of the shell is fixed.

[0021] In order to keep the capacity of the battery 14 maximum, the mainboard and the battery 14 are separated and fixed by a 0.6mm sheet metal support, the parts placed on the back of the mainboard do not exceed the thickness of the sheet metal, and the sheet metal is hollowed out at the part of the back of the mainboard.

[0022] Two Type-C interfaces, power on button 9, volume up and down buttons, menu button 3, custom button 4, back button 2, power indicator 11, system indicator 10, and microphone are placed on the main board. The ray control button 6, trigger button 5, joystick 1, speaker 17, and vibration motor 18 are placed on the sub-board.

[0023] The main board CPU, DDR, and radio frequency chip are placed on the front side, facing the upper shell 21 of the device, and are shielded by a metal shield. These devices are prone to heat, so the shield can direct the heat to the outside of the shell. The shell has heat dissipation holes 23 around the joystick.

[0024] This design fully considers human engineering. Most people are used to operating with their right hands, so the joystick 1 is placed on the front side and controlled by the right thumb. The trigger button 5 is placed on the top of the device and controlled by the right index finger. The back button 2 is placed on the lower left corner of the joystick 1, and the right thumb can directly control the back button 2 when moving away from the joystick 1. The ray control button 6 is placed on the inclined side of the rear shell and controlled by the right middle finger. The overall operation fully considers the division of labor among the fingers.

[0025] This design has a motor for motion interaction. When a certain operation is pressed, the motor provides vibration feedback. The vibration feedback is not only used for system interface interaction, but also for internal operation of various applications and game applications.

[0026] The gyroscope in this design displays a ray cursor in the 3D virtual picture of AR through the sensing of the angle direction and angular acceleration of the gyroscope. The ray control button 6 is used to control the opening, closing, and correction of the gyroscope.

[0027] The product of this design can be held vertically with one hand or rotated 90 degrees to hold horizontally with both hands. The system has a horizontal and vertical holding mode switching option.

[0028] As shown in Figure 7 According to human engineering, the holding feeling is improved, and the size of the square battery 14 is not affected by the arc curve of the shell. In this way, the size of the battery 14 is increased as much as possible to maximize the capacity of the battery 14. The convex arc is added to the lower shell 22 to achieve a better holding feeling, and the battery 14 can be made larger.

[0029] Through the way of increasing the arc of the buckle hand position of the lower shell 22, the battery capacity space is increased. Through the wrong placement of the rocker and the main board, the overall compact structure layout makes the battery space and capacity maximized in the case of maintaining the comfortable holding feeling of the small volume. The rocker function is used on the ar split main machine, and is used with the menu option jump and the control of 3D target or view angle translation, and the unique interactive design of the gyro steering control. The scheme is designed to adapt to 3D application and 3D interaction. Two gyroscopes are used in the operation interaction (one on the device and one on the glasses, used together), the rocker of the device controls the observation view angle 3D translation, the gyro of the AR glasses controls the view angle conversion, and the gyro of the device constructs a virtual ray in the 3D scene, which is used for selection and grabbing and other interactive operations in the 3D environment.
