Embodiment Construction

[0013] This specific implementation method adopts the following operation steps: the holder of the smart terminal slides to turn pages on the screen of the smart terminal, and sends the page number to the projector through WLAN, and the projector displays the slideshow of the page number after receiving the page number instruction.

[0014] The principle of sliding page turning:

[0015] Obtain the trajectory of the touch operation and judge whether it is sliding to the left or sliding to the right;

[0016] If it is sliding to the left, it is regarded as turning to the previous page. At this time, the smart terminal will send an instruction to the projector through WLAN to turn to the current page corresponding to the smart terminal;

[0017] If it is sliding to the right, it is regarded as turning to the next page. At this time, the smart terminal will send an instruction to the projector through WLAN to turn to the current page corresponding to the smart terminal.

Abstract

The invention discloses a method for controlling page turning of projector lantern slides in an intelligent terminal based on a WLAN, and relates to the field of communication. The method comprises the following operation steps that a holder of the intelligent terminal turns a page in a sliding mode on an intelligent terminal screen and sends the page number to a projector through the WLAN; the projector displays the lantern slide at the page number after receiving a page number instruction. The method solves the problem that in the prior art, a data line and the projector are connected inconveniently, left-and-right sliding gestures are used on the intelligent terminal so that an action exerted on the intelligent terminal by the holder can be acquired, the projector corresponds to the control of the intelligent terminal through the definition of the action and the triggering of an event, corresponding to the action, in the intelligent terminal, a computer and the data line are not needed, and great convenience is brought to a speaker of the lantern slides.

Description

Technical field: [0001] The invention relates to the communication field, in particular to a method for controlling slide page turning of a projector based on WLAN on an intelligent terminal. Background technique: [0002] Slide show is a presentation method often used in conferences, speeches, etc. at present. [0003] Most of the current slide shows are connected to a projector through a notebook computer, the office software installed on the computer is used to demonstrate the slide show, and the computer is used to control operations such as page turning of the slide show. [0004] The disadvantage of this control method is that the operator must have a computer, and the computer also needs a VGA cable or HDMI cable to connect to the projector. It is very inconvenient to pull the thread back and forth, and there may be cases where the thread is not long enough. It has a certain impact on the fluency of meetings and speeches, which greatly reduces the effect of presenta...
