The present application will be described in detail below with reference to the embodiments with reference to the attached drawings. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 illustrates a schematic block diagram of a multi-signal source interface interaction device, in accordance with some embodiments of the present invention.
The connection line types corresponding to the figures are as follows: 1. a network cable; usb line; 3. a bi-directional serial port line; 4, a one-way serial port line; 5. a unidirectional optical fiber; 6. and (5) video lines.
The illustrated multi-signal-source interface interaction device comprises an interaction service and instruction acquisition device 9, a switch 10, a safety instruction service box 11, a safety interface isolation box 15 and a splicing controller 16. According to some embodiments of the present invention, the apparatus may further include one or more of a command output box 12, a tiled screen 17, a display device 8', a control command generating device 8, and a wire between the components. The display screen 17 may also be a non-tiled screen.
The control instruction generating device 8 may be, for example, an infrared frame touch input device, and may also be a capacitive touch device. The control instruction generating device may capture touch or other control actions by various methods such as electric induction, magnetic induction, thermal induction, and optical induction, or may generate other control instructions, such as a mouse and a keyboard. In addition, the control instructions may also be generated via a network approach. The control command generating device 8 can generate a gesture command, a keyboard, mouse control command, or a touch command. According to some embodiments of the present invention, the control instruction generating device can be spatially superimposed on the display device 8', as will be described below, the display device 8' can provide a picture of the control object, and when the control instruction generating device is a transparent touch device, by superimposing the touch device on the display device, a visual touch can be realized on the control instruction generating device by referring to the picture of the display device 8' below the transparent touch device. The display device 8' and the control instruction generating device 8 are connected in the overall apparatus as shown in fig. 1.
The control instruction generating device can also be an infrared light curtain type touch screen based on the display device 8 'or the spliced screen 17, wherein an infrared light curtain is arranged on the surface of the display device 8' or the spliced screen 17. The infrared light curtain may be formed on the screen surface by an infrared laser or a laser array above the screen, and when the user acts on the display device 8' in which the infrared light curtain is arranged or the tiled screen 17 by a finger or the like, the touch input of the user in the screen is captured by the infrared camera. For example, when a touch is performed on the display device 8' or the tiled screen 17, the light distribution of the infrared light curtain at the touch point X will change due to the touch behavior, e.g., part of the infrared light at the touch point is diffusely reflected off the screen by the touch finger and is captured by the infrared camera located in front of the screen; or part of the infrared light at the touch point is transmitted through the screen due to the action of the touch finger (for example, when the screen is a transflective DLP screen), and then is shot by the infrared camera positioned behind the screen. Touch control can be recognized by recognizing the position of the infrared contact in the shooting result.
The splicing controller 16 is configured to process and output the input video signals, for example, after the signals are spliced with each other, or after the input signals are partially cut, the signals are displayed on a splicing screen in a certain layout. The layout comprises the window distribution size and position of each signal source on the screen. The mosaic controller may also output the content output onto the mosaic screen to the display device 8' such that the content displayed thereon is the same as the content on the mosaic screen.
The interactive service and instruction acquisition equipment is used for receiving the control instruction from the control instruction generation equipment, reading real-time layout information on a screen from the splicing controller, judging a signal source to be operated by touch according to the layout information and the touch position indicated in the control instruction, determining an output port (or a transmission link) of a safety instruction service box corresponding to the signal source by reading the configuration file, and sending the determination results to the safety instruction service box. For example, the interactive service and instruction acquisition device reads a real-time layout from the splicing controller, determines distribution positions of each signal source on the screen, and can determine that a position to which touch is applied corresponds to the signal source 14 by analyzing touch information in the control instruction, and then the interactive service and instruction acquisition device sends the related control instruction to a safety instruction service box corresponding to the signal source 14, and the safety instruction service box further sends the control instruction to the signal source, so that the interactive service and instruction acquisition device responds to the control instruction. The signal source may convert the touch coordinates in the control command into coordinates of a signal source program space in response to the control command, for example, by converting the touch coordinates (touch coordinates on the control command generating device) into screen coordinates and converting the screen coordinates into coordinates of the signal source program space), and thereby correspondingly convert the control command into an operation in the signal source program space.
According to some embodiments of the present invention, the interactive service and instruction collection device may further determine whether the control instruction corresponds to a global operation instruction; and if the control command corresponds to the global operation command, the control command is not forwarded to a signal source or a safety command service box. The global operation instruction refers to an operation instruction which is not used for controlling each specific signal source, and the global operation instruction may include, for example, an instruction for controlling the splicing controller to change the layout of each signal source on the screen, where the change includes: displaying the content of other signal sources on the screen (or called switching window) to which the current touch is applied; or, the content on the screen acted by the current touch is displayed on the whole combined spliced screen in a full screen mode (or called full screen display); or changing the size of a display window on the screen acted by the current touch; or changing the size of a display window of the display content of each signal source on the screen; or changing the position of the display window of the display content of each signal source on the screen; or pushing the content on the screen used by the current touch to other screens or screens; or switching various pre-stored layout manners, for example, a plurality of layout manners may be pre-stored, in each layout manner, the same or different signal sources (1 or more) are displayed on the screen according to a certain manner or layout, and when the touch action of the user corresponds to switching various pre-stored layout manners, the layout of the whole screen is switched every touch operation. According to some embodiments, some touches may be set to correspond to global operation instructions and other touches may be set to correspond to non-global operation instructions according to operation habits. For touches corresponding to non-global operational instructions, the corresponding touch information is sent to the corresponding signal source as described above. The touches corresponding to the global operation instruction may include, for example, O, M, C, touch gestures such as < >, or one or more fingers or a pointer sliding on the screen in some other manner, or directional touch actions (e.g., left, right, front left, front right, etc. touches corresponding to pushing a picture displayed on the screen in front of the eye to the screen on the left, the screen on the right, the screen in front of the left, the screen in front of the right, etc., respectively). The touch corresponding to the non-global operation instruction may include, for example, a double-click, a single-click, or the like touch action on the screen. According to some embodiments, some touch actions may also be introduced as boundaries for global or non-global operation instructions. For example, after one W is applied, all touches will correspond to global operation commands, and after one M is applied, all touches will correspond to non-global operation commands. For example, the interactive service and instruction acquisition device may receive the touch input gesture W, control the stitching controller to enter a screen layout adjustment mode (or called a display layout adjustment mode), and then control the stitching controller according to the movement direction and the movement distance of the gesture, so that the stitching controller responds to the instruction corresponding to the gesture to change the predetermined signal source layout mode or the size and/or position of the signal source display window. According to some embodiments, some touch actions may also be introduced as global operation instructions, and the global operation instructions are corresponding to boundaries of the global operation instructions and the non-global operation instructions. For example, after one W is applied, all touches will correspond to global operation commands, and after one M is applied, all touches will correspond to non-global operation commands. For example, the interactive service and instruction acquisition device may receive the touch input gesture W, control the stitching controller to enter a screen layout adjustment mode (or called a display layout adjustment mode), and then control the stitching controller according to the movement direction and the movement distance of the gesture, so that the stitching controller responds to the instruction corresponding to the gesture to change the predetermined signal source layout mode or the size and/or position of the signal source display window.
