The browser is a conventional application supported by a display device system, and a plurality of display devices are preset with the browser application in the system, which is mainly due to the display size of the display device, and the browsing experience by using the browser on the display device is superior to that of portable devices such as a mobile phone or a notebook computer, for example, the browsing experience can be embodied in the aspects of reading texts, watching pictures, playing videos and the like on the display device by a user. However, it is not as convenient to operate with a browser on a display device as with a portable device. Unlike the touch screen operation of a mobile phone and the mouse operation of a computer, when a browser on a display device is used to browse a page, the operation control is generally performed through a direction key on a control device.
In the embodiment of the application, the browser on the display device includes an operating mode and a virtual mouse mode, and in order to maintain the operation consistency of the browser on the display device and the browser on the portable device, the operating mode is generally switched to the virtual mouse mode when browsing a conventional page. In the virtual mouse mode, a mouse similar to a computer browser appears on the display, which is referred to as a virtual mouse in this document, and a user can control the movement of the virtual mouse on the display through a direction key on the control device and realize a click function through a confirmation key or other shortcut keys.
The function requirement of the control device determines that the key event cannot be frequently thrown upwards, so that the key event cannot be frequently thrown upwards in order to avoid misidentification of continuous keys and the like, the interval time of about 100ms generally exists between two keys, the key event can be thrown upwards every 100ms in the process of long-time pressing of a direction key, and the corresponding virtual mouse moves in a jumping manner on a display, so that poor use experience is brought to a user. In addition, when the virtual mouse moves in a jumping manner on the display, the user is hard to judge the time for releasing the direction key in sense, so that the virtual mouse is positioned on the target position, and the virtual mouse is often required to be adjusted repeatedly, thereby wasting the time of the user. For example, as shown in fig. 5, when the user presses the right direction key for a long time in the related art, the virtual mouse will move from point a to point B, from point B to point C, and from point C to point D in a jumping manner. In this process, when the user wants the virtual mouse to stop at point C, the user needs to know the timing of the virtual mouse jumping to point C, but the timing of the user selecting the release button is not well known due to the jumping movement of the virtual mouse, so that the user often needs to adjust the virtual mouse repeatedly.
In the related art, the virtual mouse moving function in the browser on the display device needs to be completed by the browser button processing module and the browser mouse drawing module together. As shown in fig. 6, the browser key processing module is in butt joint with the whole machine key processing module, and is configured to receive a key event, determine whether the key event corresponds to a direction key according to the key event, and if the key event does not correspond to the direction key, perform corresponding processing; and if the virtual mouse is a direction key, calculating the end point position of the virtual mouse and sending the end point position to a mouse drawing module. And the browser mouse drawing module draws the virtual mouse according to the end point position. As can be seen in fig. 6, for each key event, if the corresponding direction key is used, the browser key processing module converts the key event into a virtual mouse movement, and it is noted that the number and time interval of the mouse movement are consistent with the number and time interval of the up-throwing of the key event.
In order to intuitively feel the distance and frequency of the movement of the virtual mouse, a scene is preset: the display device is 65 inches in size, i.e., approximately 144cm wide, the control device is 100ms long to push the button up, and the user wishes to move the virtual mouse from the left to the right of the display in 3 s. According to the scheme in the related art, the total moving times of the virtual mouse is 30 times, the single moving distance is 4.8cm, and the time interval between two adjacent moving times is 100 ms. Because the single movement distance and the interval between two adjacent movements are large, the virtual mouse is in a state of continuous jump on the screen.
In order to avoid the above problem, an embodiment of the present application provides a method for moving a virtual mouse, as shown in fig. 7, the method includes:
s100, receiving an instruction of moving the virtual mouse through a control device key to acquire the current position of the virtual mouse.
In the embodiment of the application, the user presses the key on the control device to realize the purpose of moving the virtual mouse. In some embodiments, the browser key processing module is in butt joint with the whole machine key processing module, and is configured to receive a key event, determine whether the key event is a direction key according to the key event, and perform corresponding processing if the key event is not the direction key. And if the mouse is a direction key, acquiring the current position of the virtual mouse.
It should be noted that, when a user presses a key on the control device for a long time, a previous-polishing interval time is preset at intervals, and a key event is previously polished, the embodiment of the present application is directed to a method for moving a virtual mouse after a key event occurs. In addition, when the user presses the key on the control device for a short time, the key case is only thrown once, and the embodiment of the application moves the virtual mouse according to the key event.
