Detailed Description
The embodiment of the invention provides a touch control method and a touch control system for a large-screen display terminal, which are used for solving the technical problem that a large-size display device in the prior art influences the normal touch operation of a user due to overlarge size, so that the user is inconvenient to use.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flowchart of a touch control method for a large-screen display terminal according to an embodiment of the present invention.
The touch control method for the large-screen display terminal provided by the embodiment of the invention comprises the following steps:
s101, adding a virtual window interface on the interface to be displayed by the processing terminal according to the content to be displayed, wherein the content displayed on the virtual window interface is consistent with the content to be displayed, and the virtual window interface is smaller than the interface to be displayed.
S102, the processing terminal sends the interface to be displayed containing the virtual window interface to the large-screen display terminal, so that the large-screen display terminal displays the interface to be displayed.
It is to be understood that the processing terminal may be a computer, a notebook, or other terminal with image processing capability, and for convenience of description, the computer will be described as the processing terminal in the following description of the embodiment of the present invention. Generally, displaying a picture on a large-screen display terminal requires generating a content to be displayed on a computer, and transmitting the content to the large-screen display terminal for displaying. The large-screen Display terminal may be a large-sized Display device (such as a tiled wall) using Digital Light Processing (DLP), Light Emitting Diode (LED), Plasma Display Panel (PDP), Organic Light-Emitting Diode (OLED), or the like. In the embodiment of the invention, after the computer generates the content to be displayed, the interface to be displayed is preliminarily formed according to the content to be displayed, a smaller virtual window interface is added at the preset position of the interface to be displayed, and the content displayed by the virtual window interface is consistent with the original content to be displayed in the computer. Specifically, as shown in fig. 2, fig. 2 is a schematic view of a computer display interface according to an embodiment of the present invention. It can be understood that the content displayed on the virtual window interface can be regarded as a reduced version of the original content to be displayed on the computer, the size ratio between the virtual window interface and the interface to be displayed on the computer can be set according to actual requirements, and the preset position of the virtual window interface can also be set according to specific requirements of a user (for example, the preset position is set at the lower left corner or the lower right corner of the interface to be displayed so as to facilitate operation of the user), which is not specifically limited herein.
S103, the processing terminal obtains touch coordinates sent by a touch positioning frame arranged on the large-screen display terminal, and the touch coordinates are converted into display coordinates corresponding to the large-screen display terminal in proportion.
It should be noted that, in the embodiment of the present invention, a touch positioning frame that can be used for sensing a touch operation needs to be set on the large-screen display terminal in advance, and the size and the position of the touch positioning frame are determined according to the size and the position of the virtual window interface added on the computer. The touch positioning frame may be specifically an infrared touch positioning frame, and the infrared touch positioning frame is formed by an infrared matrix closely attached to the front of the screen in the direction of X, Y. The infrared matrix mainly comprises an outer frame, a circuit board, and transmitting tubes and receiving tubes arranged around the outer frame. The working positioning principle is as follows: when a finger or other object touches the panel of the infrared touch positioning frame, the finger or other object naturally shields a specific position on the panel, and the position can be found during screen scanning, for example, the related position of an X axis is scanned first, the Y axis is switched to and positioned at the related position immediately after the positioning is successful, and finally the specific positioned position (X, Y) is fed back to a computer, so that the corresponding touch coordinate can be obtained.
As shown in fig. 3, fig. 3 is a schematic structural diagram of a connection between a touch positioning frame on a large-screen display terminal and a computer according to an embodiment of the present invention. It can be understood that the touch positioning frame can send the multi-touch coordinates collected in the virtual window to the computer through a signal transmission line, for example, a USB port of the computer through a USB cable in real time. And the computer converts the touch coordinates acquired by the touch positioning frame into touch operation coordinate parameters on the whole large-screen display terminal according to the position parameters of the virtual window (touch positioning frame), thereby realizing the touch operation on the computer. It should be noted that, in the specific conversion process of the touch coordinate, the touch coordinate is converted into a display coordinate corresponding to the large-screen display terminal according to the set position parameter of the touch positioning frame and the size of the large-screen display terminal; the set position parameters comprise coordinates of any two opposite angles of the touch positioning frame, and the size of the large-screen display terminal comprises the width and the height of the large-screen display terminal.
For convenience of understanding, a specific process of converting the touch coordinate into a display coordinate corresponding to the large-screen display terminal by the computer in a proportional manner will be illustrated below. As shown in fig. 4, fig. 4 is a schematic diagram of an operator operating a large-screen display terminal according to an embodiment of the present invention. Wherein, the operator operates the key in the virtual window by three clicks, and the infrared positioning frame outputs the parameter f (x)0，y0). Suppose that the coordinates of one pair of opposite corners of the virtual window in the display large screen are (a)1(xa1,ya1)，a2(xa2,ya2) A width of the large screen display terminal is a and a height of the large screen display terminal is B). It is possible to obtain:
X＝(x0-xa1)*A/(xa2-xa1)
Y＝(y0-ya1)*B/(ya2-ya1)
and F (X, Y) is exactly three positions of the key in the large screen display terminal.
And S104, the processing terminal performs touch operation response on the content to be displayed according to the display coordinates, generates a corresponding display interface and sends the corresponding display interface to the large-screen display terminal.
And after the processing terminal converts the touch coordinate into a display coordinate corresponding to the large-screen display terminal, the processing terminal regards the display coordinate as a touch operation coordinate, makes a touch response to the display coordinate, and displays the responded display interface on the large-screen display terminal in real time. For example, when the user touches the corresponding key three on the touch positioning frame, the processing terminal converts the touch coordinate and then can be regarded as performing touch operation on the key three on the large-screen display terminal, so that the response of key three touch is realized, and the interface after the key three is pressed is displayed on the large-screen display terminal.
Further, in a preferred implementation manner provided by the embodiment of the present invention, when a plurality of processing terminals are connected to a large-screen display terminal through a signal processor, the signal processor receives interfaces to be displayed sent by the plurality of processing terminals, merges virtual windows in the plurality of interfaces to be displayed on one of the interfaces to be displayed, and outputs a display interface including the plurality of virtual window interfaces to the large-screen display terminal; the plurality of virtual window interfaces correspond to the plurality of processing terminals, and one interface to be displayed corresponds to one processing terminal in the plurality of processing terminals. As shown in fig. 5, fig. 5 is a schematic structural diagram of a connection between a plurality of processing terminals and a large-screen display terminal through a signal processor according to an embodiment of the present invention. It can be understood that, when a plurality of computers are simultaneously connected to the large-screen display terminal (e.g. 2 in fig. 5), a plurality of touch positioning frames corresponding to the plurality of computers may be set on the large-screen display terminal, and the signal processor may perform the screen selection display of the computers. The signal processor can select one of the pictures to be displayed according to the instruction of a user and send the picture to be displayed to the large-screen display terminal for displaying. It should be noted that, when acquiring the to-be-displayed pictures sent by the multiple computers, the signal processor combines and processes one of the to-be-displayed pictures (for example, the computer picture 1 is used as the display picture 1 of the large-screen display terminal) that needs to be displayed on the large-screen display terminal, and the virtual windows in the computer picture 1 and the computer picture 2 on the display picture 1 of the large-screen display terminal. Specifically, as shown in fig. 6, fig. 6 is a schematic view of a display screen when a large-screen display terminal is connected to a plurality of processing terminals according to an embodiment of the present invention.
When a plurality of virtual windows exist on the large-screen display terminal, a user can respectively perform touch operation on the pictures in any one of the virtual windows, the touch operation performed by the user sends corresponding touch coordinates to the signal processor through a touch positioning frame arranged on the virtual window, and the signal processor returns to the corresponding processing terminal according to the source of the touch coordinates. For example, a user performs a touch operation of a first key on the virtual window 1 corresponding to the computer screen 1, and another user performs a touch operation of a second key on the virtual window 2 of the computer screen 2, and the touch positioning frames on the virtual window 1 and the virtual window 2 are respectively connected with the touch positioning frameRespective sensed touch coordinates F1And F2Sent to a signal processor which converts the touch coordinates F1And F2Returning to the computer 1 and the computer 2 to enable the computer 1 to be capable of operating according to the touch coordinate F1Carrying out response of the first key, and sending the computer picture 1 displayed after response to a large-screen display terminal through a signal processor; and the computer 2 can be enabled to operate according to the touch coordinate F2And responding the second key, and sending the computer picture 2 displayed after the response to the large-screen display terminal through the signal processor.
It should be noted that, the signal processor may perform, according to the acquired display switching instruction, a merging process on the interface to be displayed on the processing terminal corresponding to the display switching instruction and the virtual window of the other processing terminal, and output the corresponding display interface to the large-screen display terminal. It can be understood that, in the embodiment of the present invention, a large interface displayed by a large-screen display terminal may be used as a main display interface 1 (corresponding to a virtual window 1), and a plurality of virtual windows (1 to N) are disposed on the main display interface and respectively correspond to computer images output by a plurality of computers connected to a signal processor. When the user respectively touches the virtual windows (1-N), computer pictures displayed by the virtual windows (1-N) on the large-screen display terminal and the main display interface 1 respectively respond. If the user touches any one of the virtual windows 2 to N, the main display interface 1 on the large-screen display terminal does not respond (does not change), and the corresponding one of the virtual windows 2 to N on the large-screen display terminal responds by touching. When a user needs to switch the main display interface on the large-screen display terminal, an instruction corresponding to a computer picture to be switched can be input to the signal processor, so that the signal processor can combine the interface to be displayed on the processing terminal corresponding to the display switching instruction and the virtual windows of other processing terminals according to the acquired display switching instruction, and output the corresponding display interface to the large-screen display terminal. For example, when the large-screen display terminal is correspondingly connected with the computer 1 and the computer 2, the main display interface on the large-screen display terminal is the display interface corresponding to the computer 1, and when the user 1 performs touch operation on the virtual window 1 on the large-screen display terminal, the virtual window 1 and the main display interface on the large-screen display terminal respectively make touch response; meanwhile, if the user 2 performs touch operation on the virtual window 2 on the large-screen display terminal, the virtual window 2 on the large-screen display terminal also makes a corresponding touch response. When the main display interface on the large-screen display terminal needs to be switched to the interface displayed by the virtual window 2, the user 1, the user 2 or the user 3 can send a display switching instruction to the signal processor, so that the signal processor can switch the main display interface on the large-screen display terminal according to the display switching instruction. Therefore, the embodiment of the invention realizes the touch control of the multipath computer signals on the large-screen display terminal, so that a user can respectively perform touch control on the multipath computer signals on the large-screen display terminal according to actual needs, and a corresponding computer picture is displayed on a main display interface on the large-screen display terminal through the signal processor.
In the embodiment of the invention, a path of smaller virtual window interface is added on the display interface of the large screen through the processing terminal, the display content of the virtual window interface is consistent with the content displayed by the large screen, the touch positioning frame for sensing touch operation is arranged at the position corresponding to the virtual window interface of the large screen, the processing terminal is utilized to identify the touch operation of a user on the touch positioning frame corresponding to the virtual window interface and convert the touch operation into the touch operation of the corresponding display content on the display interface of the large screen, thereby realizing the touch operation on the display interface of the large screen, ensuring that the user can control the whole large screen only by performing the touch operation on the touch positioning frame, avoiding the complexity of the user when touching the display screen, and solving the problem that the normal touch operation of the user is influenced by the oversize display device in the prior art, causing the technical problem of inconvenient use for users.
