Description

Method, device and electronic device for editing object on touch screen of electronic device

technical field

The invention relates to object editing on electronic equipment, in particular to a method and device for editing objects on a touch screen of an electronic equipment without a keyboard and the electronic equipment capable of such editing.

Background technique

For a long time, various editing methods such as text editing have brought a lot of convenience to all aspects of our lives. Recently, with the advent of electronic devices with touch screens such as mobile phones and tablet computers, input and editing functions for objects such as text have been improved to suit the characteristics of such devices. For electronic devices with touch screens, more and more people gradually use virtual keyboards to replace traditional physical keyboards to edit objects.

Several methods of object editing exist, most requiring the use of a physical or virtual keyboard. For example, text entry and erasing operations are basically performed with a physical keyboard or an on-screen virtual keyboard, selection operations are usually performed with mouse clicks or finger touch events, and other editing operations, such as insert or split operations, require both a keyboard and a mouse (or finger touch) both. For example, when a user inputs and edits text content on a personal computer (PC) or a touch-sensitive device, the user usually uses a physical or virtual keyboard for input, and determines the size and position of the text content before the input action. Users need to use the mouse or fingers to select the text content to be edited. Users can press the back key to erase the text content, and drag the selected content to the position where it needs to be inserted or divided by mouse or finger touch. With the text box, the user can insert text into the document without extra space, but the user still needs to switch between, for example, keyboard and mouse operations to edit the text content.

Patent document 1 proposes a virtual text object editing method based on Graphics Device Interface (GDI)/GDI+. The method comprises the steps of: (a) determining and generating a mouse event for the text object, (b) generating the editing state of the text object (the state of the text object determined by the mouse event), (c) if the system enters the text object editing state , the text object is ready to receive keyboard events for input. Compared with the traditional text box method, with this method, the user does not need any additional input window or widget, thus saving system resources and improving system performance. Additionally, GDI/GDI+ text objects are made more intuitive.

Moreover, in some instances, well-known methods, procedures, systems, components and/or circuits have not been described in detail in order to avoid unnecessarily obscuring claimed subject matter.

For electronic devices with touch screens such as mobile phones and tablet PCs, it is hoped that the touch screen can be completed only by clicking or touching the touch pen or the user's finger without using a physical or virtual keyboard or requiring additional display space. All the editing functions of the objects displayed on the screen can reduce the user's input operations and improve the editing efficiency and convenience.

The invention relates to a method and device for editing objects on a touch screen of an electronic device without a keyboard, an electronic device capable of such editing, and a computer-readable medium.

Figure 1 shows one example of an environment to which an example embodiment of the present invention may be applied. As shown in FIG. 1 , the application environment includes a display device 101 with a large screen, such as a flat panel display, which is mainly used for display functions. Since it also has a touch screen function, users can use a touch pen 103 or fingers to touch the screen. The display device 101 can interact with a host device 102, such as a PC. The system shown in Figure 1 can be used for conference or teaching purposes. In a conventional method, a user loads presentation material into the host device 102 and displays it through the display device 101 . The user stands beside the display device 101 and makes a speech. However, when the user wants to edit the material, such as inserting a note or modifying the material, the user must go to the host device 102 to use the keyboard and mouse to edit. Then, the user returns to the display device 101 to continue speaking. When more editing is required, the user has to repeat the above process many times.

According to an exemplary embodiment of the present invention, after the speech material is loaded into the host device 102 and displayed by the display device 101, the user can stand beside the display device 101 and use the touch pen 103 to directly edit on the screen during the speech, while No need to go back and forth. Specifically, according to an exemplary embodiment of the present invention, when the user needs to edit, the user may input a mode switching command via a button on the touch screen or a button on the touch pen 103 . The host device 102 receives the mode switching command, analyzes it and switches to the corresponding editing mode. Editing modes may include modes such as erase, insert, modify, and split. In the editing mode, the user can input editing actions through the touch pen 103 or fingers on the touch screen. The host device 102 receives the editing action, analyzes the editing action, and performs object editing according to the editing action and the object information of the displayed object. Here, the editing action may include actions input by the user for operations such as erasing, inserting, modifying, and splitting. For example, for an erasing operation, the user can use the touch pen 103 or a finger to draw an oblique pattern on the text or characters to be erased. For the insertion operation, the user can use the touch pen 103 or a finger to select the object to be inserted and drag the object to the insertion position. For the modification operation, the user can use the touch pen 103 or a finger to select an object to be modified. For the segmentation operation, the user can use the touch pen 103 or a finger to draw, for example, a circular or square wire frame to frame the object to be segmented. The object information of the display object may include at least one of type information, location information, font information, color information, size information, content information, and graphic information of the display object. The object information of the displayed object may be stored in advance, or generated and stored when the user inputs the displayed object (such as characters or symbols). In an example embodiment, before switching to the editing mode, the user may switch to the handwriting mode by inputting a mode switching command via a button on the touch screen or a button on the stylus 103 . The user can use the touch pen 103 or a finger to handwrite characters or draw symbols on the screen. The host device 102 converts the handwritten input into text or symbolic objects and displays them on the screen. Prior to this or at the same time, the host device 102 may store information of the displayed object in, for example, a memory as object information. The handwriting input can be converted by techniques well known to those skilled in the art, such as handwriting recognition technology (HWR) to recognize the user's handwriting content.

In the above example, although it is shown that the host device 102 and the display device 101 are separate components, those skilled in the art can understand that the host device 102 and the display device 101 may also be integrated to form a whole electronic device, for example Mobile Phones, Personal Digital Assistants (PDAs), Tablets, etc. Fig. 8 shows a schematic functional block diagram of an electronic device according to an exemplary embodiment of the present invention.

These examples are described below in conjunction with the apparatus 200 shown in FIG. 2 .

FIG. 4 is a schematic diagram illustrating an erase operation according to an exemplary embodiment of the present invention. In FIG. 4, the displayed object is text content 401, such as a GDI/GDI+text object. Here, the text content is only an example, and the displayed objects may also include other types of objects, such as symbols, graphics, images, and the like. In order to erase text content, you first need to switch to erase mode. The switching instruction can be triggered by clicking a virtual button on a touch screen or clicking a touch pen button on a touch pen. The input unit 201 receives the switching instruction and sends it to the analyzing unit 202 . The analysis unit 202 receives the switching instruction and switches the electronic device to the erasing mode. In the erase mode, the user inputs an erase slash 402 on the touch screen with a finger or a stylus. The input unit 201 receives the erasing slash 402 and sends it to the analysis unit 202 . The analysis unit 202 analyzes the received erasing slash 402 and generates information about the erasing slash 402 , such as location information. Since the storage unit 205 stores the information of the text content 401 , such as graphic information, the analysis unit 202 can obtain the stored graphic information of the text content 401 from the storage unit 205 . The analysis unit 202 can determine the part of the text content to be erased, such as the character 402 , based on the graphic information and the location information of the erased slash 402 .
