Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments 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, a method for annotating screen shot content provided by an embodiment of the present invention includes, for example, the steps of:
s11: displaying screen projection content in a screen projection window;
s13: responding to a user trigger operation to enter an annotation mode so as to generate a transparent annotation editing window and placing the transparent annotation editing window above the screen projecting window for a user to write annotation content in the annotation editing window, wherein the annotation editing window has scroll bar attributes and coordinate mapping is established between the annotation editing window and the screen projecting window; and
s15: responding to a sliding touch gesture of a user in the annotation editing window, and controlling the screen casting content in the screen casting window and the annotation content in the annotation editing window to synchronously move.
In order to more clearly understand the screen-casting content annotation method of the present embodiment, the following description will be made with reference to fig. 2, 3A, and 3B.
Specifically, the screen-casting content annotation method of the present embodiment is adapted to be executed on the display device 15 in the conference screen system 10 shown in fig. 2. As shown in fig. 2, the conference screen system 10 includes: a source device 11, a wireless screen projector 13 and a display device 15. The source device 11 is, for example, a notebook computer or other electronic device that is also configured with a processor, a memory, and a display screen and is installed with an operating system (e.g., windows, Mac OS/X, Linux, Android, iOS, etc.) that can establish a wireless network communication connection with the display device 15 in a wireless manner based on the wireless projector 13. In other embodiments, the source device 11 may also directly display the projected content in a wireless manner on the display device 15 without connecting a wireless projector. Moreover, the wireless screen projector 13 can be a mature screen projector with physical keys; the display device 15 is, for example, an LCD display screen with touch control function, an LED display screen with touch control function, or other display screens with touch control screens.
In summary, the method for annotating the screen casting content in this embodiment is based on the technical scheme of the linkage of the screen casting content and the annotation content, and the method uses a slidable window design when creating the annotation editing window 153, and binds the operations of sliding, page changing and the like for the annotation editing window 153 and the screen casting window 151, so that the two windows are synchronously linked to realize the operation, and the user can realize the operation on the screen casting window 151 without exiting the annotation editing window 153, and the specific implementation manner is as follows.
The functions of displaying the screen-cast content and editing the annotation are realized through the two windows, i.e., the screen-cast window 151 and the annotation editing window 153, respectively, the default annotation editing window 153 is not created when the screen-cast content is displayed/presented (corresponding to step S11), and the annotation editing window 153 is created when the annotation mode is entered. Here, the user triggering operation entering the annotation mode may be clicking an annotation control displayed on the screen of the display device 15, and the triggering operation is a mature technology in the prior art, and therefore is not described herein again; still alternatively, the user triggering operation entering the annotation mode is a single-point continuous sliding touch operation in the screen projecting window 151, because the writing operation of the user in annotating is generally a single-point continuous sliding touch operation, the beneficial effect that the user automatically enters the annotation mode to create the annotation editing window 153 once the user is detected to start writing operation can be achieved, and the annotation control does not need to be clicked.
When entering the annotation mode (corresponding to step S13), the transparent annotation editing window 153 with ScrollBar attribute is created for the user to write the annotation content in the annotation editing window 153, because the annotation editing window 153 with scroll bar attribute supports the sliding touch gesture to expand and change pages downward.
Further, a coordinate mapping is established between the annotation edit window 153 and the screen projection window 151, for example, a pixel-based coordinate mapping is established, so that annotation contents and screen projection contents are in one-to-one correspondence by pixel.
In addition, the instruction data of the sliding touch operation on the comment editing window 153 and the instruction data of the page operation on the screen-projected content in the screen-projected window 151 are shared and bound, and the linkage between the screen-projected window 151 and the comment editing window 153 is realized by unifying the touch gesture operation processing function and the response function of performing the page operation on the screen-projected content in the screen-projected window 151 through an input device such as a keyboard or a mouse on the source device 11; as such, when the annotation editing window 153 executes a sliding touch gesture, such as the multi-point sliding touch performed by multiple fingers simultaneously (corresponding to step S15) shown in fig. 3B, the window object is not eliminated, and the window content exists until the window exits; and when the user performs page operations such as page content scrolling or page changing on the screen-shot content through the input device on the source device 11, the annotation content in the annotation editing window 153 can be controlled to synchronously follow.
In summary, based on the screen-casting content annotating method of the embodiment, the user can pull up and pull down the screen-casting content through the sliding touch gesture in the annotating mode, and the annotating content can move synchronously with the screen-casting content; during the whole screen-casting content demonstration period, the user does not need to add redundant operation to switch the window, and the annotation content synchronously follows the screen-casting content, so that the user operation is simplified, the application habit of the user is more suitable, the interaction process is more friendly to the user, and the user experience is greatly improved.
