Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
In the prior art, a remote desktop service manufacturer adds functions such as a floating button and gesture operation in a remote desktop, so that when a user terminal is not connected with an external input device but needs to input in an input box of the remote desktop, the user terminal can autonomously call out a text keyboard function of the remote desktop by clicking the floating button or making a gesture. However, the intelligent degree of the mode is low, the operation is not convenient enough, and the user experience is influenced. In view of this, the embodiment provides a virtual keyboard calling method, so that when a user uses a user terminal without a peripheral to control a remote desktop to perform a text input operation, the user terminal can display a virtual keyboard in a screen for the user to input only by clicking in an input box of the remote desktop, the operation is simple, convenient and fast, and the user experience is greatly improved.
As shown in fig. 1, the user terminal is communicatively connected to the remote server. The user terminal includes, but is not limited to, devices such as smart phones, tablet computers, and portable computers, and the remote server includes, but is not limited to, a single server and a server group. The user terminal is provided with a client, and is connected to and accesses the remote server through the client (such as app and wap). The remote server provides a remote desktop to the user terminal, and the user terminal displays the remote desktop, for example: the remote server provides the virtual cloud desktop to the user terminal, and the user terminal displays the virtual cloud desktop.
The virtual keyboard calling method of the embodiment comprises the following steps:
s21: the user terminal acquires the pressing and lifting events and transmits the pressing and lifting events to the remote server.
Specifically, the generation of press and click events is, for example: the user operates an external mouse connected with the user terminal, moves the mouse to a destination (such as an input box) of a remote desktop, and executes the operation of pressing and lifting a left button of the mouse, or the user operates a touch screen of the user terminal, and executes the pressing and lifting operation after a cursor is dragged to the destination (such as the input box) by a finger, or directly clicks the destination (such as the input box) to execute the pressing and lifting operation without dragging the cursor in a touch screen mode.
After acquiring the pressing and lifting event (such as the pressing and lifting event of the left mouse button), the user terminal sends the pressing and lifting event to the remote server. Preferably, in an embodiment, the ue sends the location coordinates of the press and lift events to the remote server.
In other embodiments, when the user terminal is connected to an external input device, such as a mouse, a physical keyboard, a tablet, etc., the user may select to close the function of the virtual keyboard, that is, the user terminal may stop sending the obtained press-down and lift-up events and the position coordinates thereof to the remote server.
S22: and the remote server side receives the pressing and lifting events sent by the user terminal and then acquires the current cursor type of the remote desktop.
In an embodiment, after receiving the press and lift event and the position coordinates thereof, the remote server calculates the corresponding position coordinates of the press and lift event in the remote server according to the resolution of the user terminal and the resolution of the remote server. For convenience of description, the occurrence position of the press-and-lift event in the user terminal is referred to as a first coordinate, and the corresponding position of the first coordinate in the remote server is referred to as a second coordinate. For example: the resolution of the ue is a × b, the resolution of the remote server is c × d, and assuming that the first coordinate is (m, n), the second coordinate should be (c/a × m, d/b × n). The remote server executes the press and lift events at the second coordinate location.
In an embodiment, the press and lift events received by the remote server further include a press operation timestamp and a lift operation timestamp. And the remote server calculates the time difference between the pressing operation and the lifting operation of the pressing and lifting event according to the two timestamps, judges that the pressing and lifting event is a click event after the time difference meets a preset condition (if the preset time difference is 200ms, the calculated time difference is less than 200ms, the calculated time difference is considered to meet the preset condition), executes the click event at a second coordinate position, and then calls the system api to acquire the type of the mouse cursor currently displayed on the remote desktop. Preferably, all click events in this embodiment refer to left click events.
S23: and the remote server identifies the cursor type, and if the cursor type is an input cursor, a notification message that the current user needs to input the text is sent to the user terminal.
Specifically, the remote server judges the type of the acquired cursor, determines that a point clicked by a user is an input box and needs to input a text if the cursor type is IBEAM (in other words, an I-shaped cursor), and then sends a notification message to the user terminal.
S24: and after receiving the notification message sent by the remote server, the user terminal displays the virtual keyboard on a screen.
And when the user terminal receives the notification message returned by the remote server, calling the virtual keyboard to be displayed in a screen so as to allow the user to perform input operation. The virtual keyboard may include all keys or some keys in the physical keyboard, or other keys added by the manufacturer, such as symbol keys, emoticon keys, and so on.
All or part of the steps for implementing the above method embodiments may be performed by hardware associated with a computer program. Based upon such an understanding, the present invention also provides a computer program product comprising one or more computer instructions. The computer instructions may be stored in a computer readable storage medium. The computer-readable storage medium can be any available medium that a computer can store or a data storage device, such as a server, a data center, etc., that is integrated with one or more available media. The usable medium may be a magnetic medium (e.g., floppy Disk, hard Disk, magnetic tape), an optical medium (e.g., DVD), or a semiconductor medium (e.g., Solid State Disk (SSD)), among others.
