For example, default display setting information (such as default display positions, default display styles corresponding to various data formats, and the like) is stored in advance in the storage unit of the keyboard, and the processing module reads the default display setting information from the storage unit. For another example, the user inputs display setting information of the user for content information to be currently displayed through the input module 103 on the keyboard, and the input module 103 provides the display setting information to the processing module, based on which the user can input the display setting information based on own habits or current needs.

As an implementation manner of the preferred embodiment, the control module obtains a control instruction provided by the first interface unit 101 for controlling the virtual reality device, or obtains a control instruction provided by the second interface unit 102 for controlling the terminal device.

It should be noted that, the first interface unit 101 or the second interface unit 102 may first provide the received control instruction to the processing module, and then the processing module provides the control instruction to the control module, that is, the processing module identifies the control instruction; alternatively, the first interface unit 101 or the second interface unit 102 may directly provide the received control instruction to the control module, that is, the first interface unit 101 or the second interface unit 102 has the capability of recognizing the control instruction.

As an example, a control instruction for the virtual reality device is generated in the terminal device and sent to the keyboard, and a control module of the keyboard obtains the control instruction and provides the control instruction to the second interface unit 102, so that the control instruction is sent to the virtual reality device through the second interface unit 102, thereby controlling the virtual reality device through the keyboard by the terminal device. Similarly, the virtual reality device can control the terminal device through the keyboard.

As another implementation manner of the preferred embodiment, the user input information includes the control instruction, and the control module obtains the control instruction provided by the input module 103.

Preferably, the keyboard is provided with at least one specific key corresponding to at least one control instruction, and the user can issue the corresponding control instruction by pressing the specific key.

As an example, a user inputs a control instruction by clicking a specific key on the keyboard, and the control module obtains the control instruction provided by the input module 103 and provides the control instruction to the first interface unit 101, so as to send the control instruction to the terminal device through the first interface unit 101, thereby enabling the user to control the terminal device through the keyboard. Similarly, the user can control the virtual reality device through the keyboard.

It should be noted that, the two implementation manners may be combined, and the control module may receive a control instruction from the terminal device or the virtual reality device, and may also receive a control instruction included in the user input information.

It should be noted that, the above examples are only for better illustrating the technical solutions of the present invention, and not for limiting the present invention, those skilled in the art should understand that any control module is used to obtain a control command, and provide the control command to the first interface unit or the second interface unit, so as to send the control command to the terminal device or the implementation manner of the virtual reality device, which all should be included in the scope of the present invention.
