detailed description

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a first embodiment of an input control method for a projection device according to the present invention; this embodiment is described from the projection device side. In this embodiment, the input control method of the projection device includes:

Step S110, the projection device detects whether the focus of the current projection interface is located on the text input box;

Step S120, if yes, send predetermined feedback information to the mobile terminal communicatively connected with the projection device to notify the mobile terminal to input text for display in the text input box;

In this embodiment, generally, the projection device is provided with a variety of operation interfaces to facilitate the user to control the projection device through a remote control or other devices, such as a text input box for inputting text, a search interface, a search button control, etc. When the device is operated remotely, the focus of the current operation will generally be displayed on the projection interface, such as a button highlighted, or displayed in the form of a cursor, thereby informing the user of the current control point on the projection interface.

In this embodiment, the projection device detects the focus position in real time to determine whether the current focus position is located on the text input box. In this embodiment, positioning the focus on the text input box may include three types of situations:

(1) In the same projection interface, the focus is transferred from other controls to the text input box; in such cases, the user can control the focus to move to the text input box through a remote control or other devices;

If this is the case, after receiving a focus movement instruction sent by a remote control or other equipment (such as a mobile terminal) for controlling the focus to move between controls, the projection device executes a focus movement operation corresponding to the focus movement instruction , and check whether the current focus is located on the text input box after the focus moves.

(2) Jump from one projection interface to another projection interface, and the focus of the projection interface after the jump is positioned on the text input box by default;

If this is the case, after the projection device receives the page turning instruction sent by the remote control or other devices (such as a mobile terminal), it executes the page jump operation corresponding to the page turning instruction, and detects the page turning operation in the current projection interface after the page jumps. Whether the focus is initially positioned on the text input box, wherein the page turning instruction is specifically used to control the projection device to execute the operation of jumping from the current projection interface to the projection interface specified by the page turning instruction.

(3) The focus of the first projection interface launched when the projection device is started is positioned on the text input box by default;

If this is the case, the projection device needs to detect whether the focus in the initial projection interface is initially positioned on the text input box when it projects the initial projection interface after booting.

If the projection device detects that the focus of the current projection interface is positioned on the text input box, that is, when any of the above three types of situations exists, the projection device will send predetermined feedback information to the mobile terminal. In this embodiment , the specific setting of the feedback information is not limited, and the feedback information is specifically used to inform the mobile terminal that the focus of the projection interface has been shifted or positioned to the text input box and the mobile terminal needs to input text into the text input box. For example, the feedback information can be set by agreement between the projection device and the mobile terminal.

In addition, it needs to be further explained that the projection device may only send predetermined feedback information to the mobile terminal when the focus of the current projection interface is positioned on the text input box, and when the focus is positioned on other controls outside the text input box, The projection device may not send any feedback information to the mobile terminal.

Step S130, receiving the text sent by the mobile terminal for displaying in the text input box;

Step S140, displaying in the text input box the received text sent by the mobile terminal for display in the text input box.

In this embodiment, after the mobile terminal receives the feedback information sent by the projection device and enters the text to be displayed in the text input box, it sends the input text to the projection device; the projection device receives the text sent by the mobile terminal for The text displayed in the text input box is displayed in the text input box.

In this embodiment, there is no limit to the method of generating the text sent by the mobile terminal to be displayed in the text input box. For example, the user is first prompted to select the corresponding text input method, or the most commonly used virtual input for text input by the user pops up directly. controls, such as a virtual keyboard or voice input, etc., and then complete text input through the virtual input control to generate corresponding text for display in the text input box.

Optionally, when the mobile terminal receives the feedback information sent by the projection device, the mobile terminal will start its own virtual input method application, thereby popping up a virtual input control (such as a virtual input keyboard, pinyin input or handwriting input) so that the user can Text input on the virtual input control. Wherein, the user can further select and set the type of the virtual input control (such as a keyboard), the type of the input method, and the like.

Optionally, when the mobile terminal detects a text sending instruction, the text sending instruction can be triggered by the user touching the send button on the virtual input keyboard, and the mobile terminal sends all the text input by the user on the virtual input keyboard One-time sending to the projection device for display in the text input box on the projection device, so as to avoid directly inputting text through multiple selection operations on the remote control or other devices on the projection interface, thereby improving the convenience of the user's text input operation .

In addition, it needs to be further explained that when the input text is used for searching, in order to avoid real-time input, each input text needs to be searched separately, thereby reducing the accuracy of the search results, so in this embodiment , preferably by sending all the text to the projection device at one time, so that the projection device can accurately obtain the required search results only through one search.

In this embodiment, by monitoring whether the focus of the projection interface is located on the text input box, if so, the projection device is triggered to send feedback information to the mobile terminal to inform the mobile terminal that text input is required, thereby improving the text input response speed. In addition, the projection device displays the received text input through the mobile terminal in the text input box, so that the user does not need to input text by operating the input panel on the projection interface, thereby improving the convenience of the text input operation.
