Embodiment 1

[0039] figure 1 It is a schematic flow chart of a virtual mouse control method according to an embodiment of the present invention, see figure 1 , the method includes the following steps:

[0040] Step S11, using the sensor set in the head-mounted display device to collect the user's head movement data;

[0041] Step S12, calculate the collected head movement data, and obtain the two-dimensional coordinate value corresponding to the coordinate system where the display screen of the head-mounted display device is located;

[0042] Step S13 , according to the obtained two-dimensional coordinate value, control the virtual mouse of the head-mounted display device to perform a corresponding mouse movement operation on the display screen. The virtual mouse in this embodiment is relative to the physical mouse connected externally to the head-mounted display device.

[0043] Depend on figure 1 As can be seen from the method shown, this embodiment collects the user's head movement ...

Embodiment 2

[0045] figure 2 It is a schematic diagram of a virtual mouse control method according to another embodiment of the present invention, see figure 2 The virtual mouse control method of this embodiment is implemented based on the Android platform, that is, the head-mounted display device is installed with an Android operating system, and is provided with sensors and physical buttons.

[0046]When the system of the head-mounted display device is turned on, the system first controls to display the virtual mouse (such as displaying a mouse pointer) at the position corresponding to the preset initial coordinate value of the display screen, and then when the user wearing the device turns his head, the sensor Collect data in real time;

[0047] see figure 2 , step 2.1, the driver application program of the driver layer (Kernel) collects data from the nine-axis sensor of the head-mounted display device, obtains the nine-axis data of the user's head movement, and then uploads the ni...

Embodiment 3

[0059] image 3 It is a structural block diagram of a virtual mouse control device according to an embodiment of the present invention, see image 3 , the control device 30 of the virtual mouse in this embodiment includes:

[0060] The data acquisition unit 301 is used to collect the head movement data of the user by using the sensor provided in the head-mounted display device, and send the head movement data to the coordinate value calculation unit 302;

[0061] The coordinate value calculation unit 302 is used to calculate the collected head movement data to obtain the two-dimensional coordinate value of the coordinate system corresponding to the display screen of the head-mounted display device, and send the two-dimensional coordinate value to the virtual mouse control unit 303;

[0062] The virtual mouse control unit 303 is configured to control the virtual mouse of the head-mounted display device to perform corresponding mouse movement operations on the display screen ac...

Abstract

The invention discloses a control method and control device of a virtual mouse, and head-mounted display equipment. The control method of the virtual mouse comprises the following steps: utilizing a sensor arranged in the head-mounted display equipment to collect the head movement data of a user; calculating the collected head movement data to obtain the two-dimensional coordinate value of a coordinate system where a display screen corresponding to the head-mounted display equipment is positioned; and according to the two-dimensional coordinate value, controlling the virtual mouse of the head-mounted display equipment to execute a corresponding mouse movement operation on the display screen. The control method and the control device of the virtual mouse directly control the movement of the virtual mouse according to the head movement of the user, and omit an external physical mouse. Therefore, the head-mounted display equipment is accurate in input control, is convenient in user operation and improves use experience. In addition, the head-mounted display equipment disclosed by the invention adopts the virtual mouse control device, so that convenience is brought for users to control, and product competitiveness is improved.

Description

technical field [0001] The present invention relates to the technical field of head-mounted display devices, in particular to a virtual mouse control method, a control device and a head-mounted display device. Background technique [0002] At present, with the development of head mounted display devices (Head Mount Display, HMD) and virtual reality technology, users have more and more urgent demands on content diversity of head mounted display devices. Because there is no uniform standard for the existing head-mounted display devices, the content supported by the head-mounted display devices is relatively scarce, and usually only supports 3D applications such as 3D games, and is not compatible with 2D applications. [0003] If the head-mounted display device can be compatible with 2D applications, it will undoubtedly greatly enrich the content of the head-mounted display device. However, when the head-mounted display device is used, it needs to be worn on the user's head. I...
