When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present specification. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present description as detailed in the accompanying claims.
In order to solve the problems in the background technology, the application provides a screen-throwing windowed reverse touch control method which is applied to an intelligent screen. The smart screen includes an operating system and a display system. The operating system implements various software applications and intelligent operations. The system such as Windows or Android can be used here. The display system is mainly used for displaying and mainly comprises a large screen, accessories and the like. The operating system and the display system perform data transceiving interaction through a communication protocol. The communication connection is typically established through a serial port or USB or Tab line or the like. The method in the embodiment of the application, as shown in fig. 1, includes:
101: establishing input connection and reverse touch connection with an input source;
the input connection with the input source can be a wired connection, such as an HDMI wire or a USB wire, or a wireless WiFi connection, so that the input source and the intelligent screen are connected in the same network. The input source here may be a computer, ipad, medical device, etc. The video picture is input to the large screen device by establishing an input connection with the smart screen. Remote video transmission can also be performed if an HDMI line is used.
The reverse Touch connection is established mainly through the Touch Out line. The input source picture is transmitted to the large screen and displayed, and touch data can be transmitted to the input source by clicking the input source picture on the large screen in a touch mode, so that the input source responds to touch operation. The Touch Out line is a device through which a Touch device can transmit Touch data to another end connection.
102: the large screen at least comprises an input source region picture and a first column region picture, and the first column region picture layer level is higher than the input source region picture layer level;
the pictures are in hierarchical relation with each other, and the effect of the hierarchical most direct representation is shielding. The layer level below the layer palette is lower, and higher the level. Generally, when a layer level is overlaid on a layer of a picture having a low level, a picture having a high level is easily seen and can be operated. The screen level can be set when the UI interface is designed. If one wants to see a low-level picture, this can be done by tuning to the transparency of the high-level interface. In the embodiment of the application, the first column region picture layer level is higher than the input source region picture layer level, so that the first column region can be controlled when the input source picture is watched, and the multi-software cooperative operation is realized.
103: the operating system acquires the coordinates (x 1, y1, w1, h 1) of the input source region on the large screen and sends the coordinates to the display system through a communication protocol;
the large screen is provided with an initial origin. The device can be arranged at any end point of a large screen or in the center, and is based on actual arrangement. The input source picture region is provided with a default initial picture size region S when projected onto a large screen. The coordinates of each vertex can be obtained according to the distance between each vertex of the area and the far point. The coordinates are sent to a display system through a communication protocol, and are mainly displayed on a large screen. The communication protocol here may be a serial port, USB or Tab protocol, etc. If the HDMI line is used to connect the input source, the HDMI tool area may be directly popped up on the large screen, and the area except the toolbar area of the HDMI tool area may be directly used as the input source screen area to display the input source data. Of course, the size and position of the input source frame area can be adjusted again in the actual use process. For example, moving or scaling, the parameter adjustment of the generated response can also be obtained by measuring the distance from the initial origin of the large screen.
104: the operating system acquires a click position P1 (xp, yp) and transmits the click position P1 (xp, yp) to the display system through a communication protocol;
the clicking operation is realized by means of, for example, a pen or a hand touch, a mouse, etc. And the operating system calculates and obtains the P1 coordinate of the clicking position according to the distance between the clicking position and the initial origin of the large screen. The communication protocol here may be a serial port, USB or Tab protocol, etc.
105: and judging whether the clicking position P1 (xp, yp) is in the input source picture area, and if so, performing reverse touch control.
The determining that the click position P1 (xp, yp) is within the input source picture region includes:
xp > x1, and xp < x1+w1;
yp > y1, and yp < y1+h1.
And if yes, performing reverse touch control, and enabling the input source to respond to corresponding touch control operation by operating on the large screen.
The method comprises the following steps:
1051: the operating system is required to acquire the large screen resolution (xs, ys);
1052: clicking a position P1 (xp, yp) to reversely touch and screen the corresponding coordinate P2 (xp ', yp ') of the input source, wherein xp ' = (xp-x 1) xs/w1; yp' = (yp-y 1) ys/h1.
According to the embodiment of the application, reverse touch control is realized through input source screen projection windowing, operation can be realized on a non-input source area, and multi-software cooperative operation is realized.
In a second embodiment of the present application: as shown in fig. 2, the method further comprises the following steps in the implementation of the method:
201: if the clicking position P1 (xp, yp) is not in the input source picture area, acquiring a first column area coordinate (x 2, y2, w2, h 2), and transmitting the first column area coordinate to a display system through a communication protocol;
the method of acquiring the first column region coordinates (x 2, y2, w2, h 2) is the same as the input source region coordinates (x 1, y1, w1, h 1). The coordinates of each vertex can be obtained according to the distance between each vertex of the area and the far point.
202: whether the clicking position P1 (xp, yp) is in the first column picture area or not is judged, and if so, the reverse touch control is turned off.
Similarly, the judgment of the click position P1 (xp, yp) in the first column screen region includes:
xp > x2, and xp < x2+w2;
yp > y2, and yp < y2+h2.
In this embodiment, the steps described above are not necessarily performed in the order of steps described above. For example, the judgment step 105 and the judgment step 106 judge whether P1 is simultaneously available in the input source picture region. For example, the large screen resolution (xs, ys) and the first column region coordinates (x 2, y2, w2, h 2) can be acquired simultaneously with the input source region coordinates (x 1, y1, w1, h 1), or the input source region coordinates are early removed, so that the protection scope of the application is not affected.

301: the large screen is also provided with a second column region picture, and the layer level of the second column region picture is higher than that of the input source region picture;
the second column region screen level here is obtained by UI interface setting as with the first column region screen level. The first and second column regions may be operation columns, such as task columns, on a smart screen. The first and second column regions may be either transverse or longitudinal, although they may be both in the same direction, depending on the actual design requirements.
302: the operating system acquires the second column region coordinates (x 3, y3, w3, h 3) and sends the second column region coordinates to a display system through a communication protocol;
303: if it is determined that the click position P1 (xp, yp) is not in the input source region or in the first field screen region, the determination that the click position P1 (xp, yp) is included in the second field screen region includes:
