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:
The present invention relates to the communications field, specifically is the method for controlling the page turning of projector lantern slide on a kind of intelligent terminal based on WLAN.
Background technology:
Slideshow is that the PowerPoint mode is often used in present meeting, speech etc.
Present slideshow is to connect projector by notebook computer mostly, comes presentation slides by the office software of adorning on the computer, controls the operations such as page turning of lantern slide with computer.
The drawback of this control mode is that the operator must have computer, and computer also needs VGA line or HDMI line to connect projector.Line La Laila goes very inconvenient, also can occur the situation that line falls short of.Fluency to meeting, speech produces certain influence, makes the big heavy discount of demonstration effect.
Summary of the invention:
The purpose of this invention is to provide the method for controlling the page turning of projector lantern slide on the intelligent terminal based on WLAN, it solves the existing inconvenience that connects projector with data line, by use the gesture that horizontally slips at intelligent terminal, know what action hand-held person makes to intelligent terminal, and by the triggering to corresponding event in the definition of this action intelligent terminal corresponding with this action, the control of projector and intelligent terminal is mapped, do not need to accomplish computer and data line, greatly made things convenient for the speaker of lantern slide.
In order to solve the existing problem of background technology, the present invention adopts following operation steps: the intelligent terminal possessor is in the enterprising line slip page turning of intelligent terminal screen, and the page number sent to projector by WLAN, projector receives page number instruction back and shows this page number lantern slide.
The principle that slides page:
Obtain the movement locus of touch control operation, and be judged as the slip to the right of sliding still left;
If slide left, then be considered as translating into prevpage, this moment, intelligent terminal can send to translating into instruction current and the corresponding page number of intelligent terminal to projector by WLAN;
If slide to the right, then be considered as translating into the next page, this moment, intelligent terminal can send to translating into instruction current and the corresponding page number of intelligent terminal to projector by WLAN.
Obtain the movement locus of touch control operation, and be judged as left to slide and still slide to the right, adopt following steps: establish the X-Y horizontal coordinates at screen, obtain the coordinate (x1 of the starting point A of touch control operation movement locus, y1) and terminal point coordinate (x2, y2), slide if the coordinate x1 of starting point then is judged as left greater than the x2 of terminal point coordinate, slide if the coordinate x1 of starting point then is judged as to the right less than the x2 of terminal point coordinate.Adopt this method, when user's intelligent terminal on-screen options is done, even sliding trace is not horizontal linear, can realize that also touch-control accurately controls, the user can be with being intended to slide experience degree height on the screen.
The present invention has following beneficial effect: by use the gesture that horizontally slips at intelligent terminal, know what action hand-held person makes to intelligent terminal, and by the triggering to corresponding event in the definition of this action intelligent terminal corresponding with this action, the control of projector and intelligent terminal is mapped, do not need to accomplish computer and data line, and under the wireless local environment, corresponding man-machine interactive operation when intelligent terminal is done action and can be finished the projector slideshow has greatly made things convenient for the speaker of lantern slide.
Embodiment:
This embodiment adopts following operation steps: the intelligent terminal possessor is in the enterprising line slip page turning of intelligent terminal screen, and the page number is sent to projector by WLAN, and projector receives page number instruction back and shows this page number lantern slide.
The principle that slides page:
Obtain the movement locus of touch control operation, and be judged as the slip to the right of sliding still left;
If slide left, then be considered as translating into prevpage, this moment, intelligent terminal can send to translating into instruction current and the corresponding page number of intelligent terminal to projector by WLAN;
If slide to the right, then be considered as translating into the next page, this moment, intelligent terminal can send to translating into instruction current and the corresponding page number of intelligent terminal to projector by WLAN.
Obtain the movement locus of touch control operation, and be judged as left to slide and still slide to the right, adopt following steps: establish the X-Y horizontal coordinates at screen, obtain the coordinate (x1 of the starting point A of touch control operation movement locus, y1) and terminal point coordinate (x2, y2), slide if the coordinate x1 of starting point then is judged as left greater than the x2 of terminal point coordinate, slide if the coordinate x1 of starting point then is judged as to the right less than the x2 of terminal point coordinate.Adopt this method, when user's intelligent terminal on-screen options is done, even sliding trace is not horizontal linear, can realize that also touch-control accurately controls, the user can be with being intended to slide experience degree height on the screen.
The present invention is illustrated by above-described embodiment, but should be understood that, above-described embodiment just is used for for example and illustrative purposes, but not is intended to the present invention is limited in the described scope of embodiments.It will be appreciated by persons skilled in the art that in addition the present invention is not limited to above-described embodiment, can also make more kinds of variants and modifications according to instruction of the present invention, these variants and modifications all drop in the present invention's scope required for protection.Protection scope of the present invention is defined by the appended claims and equivalent scope thereof.
