Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The method of a kind of mobile terminal demonstration PPT document that the embodiment of the present invention provides and device, cursor can be moved according to the change of mobile terminal attitude or draw mark line, user's one-handed performance just can move cursor or draw mark line, the demenstration method of hinge structure, simplify operation, it is possible to bring better experience to user.
It show a kind of schematic flow sheet of the method for a kind of mobile terminal demonstration PPT document of the embodiment of the present invention referring to Fig. 1, Fig. 1, comprises the following steps:
Step S101, opens PPT documented instructions according to user, the PPT document that screen and the PPT projection screen simultaneous display at mobile terminal is opened；
Mobile office software popular on the market at present, much already by technology such as " sharing WiFi ", it is achieved that show the function of the PPT document opened at mobile terminal screen and PPT projection screen simultaneously.Principle is by shared WiFi technology mostly, mobile terminal and the notebook computer for demonstrating PPT document is first made to share PPT document, then mobile terminal and notebook computer are controlled, it is achieved the PPT document that screen and the PPT projection screen simultaneous display at mobile terminal is opened.Concrete implementation process, belongs to prior art, repeats no more here.
When opening PPT document, light target original position can be arranged on any position of screen, is generally arranged at the position of screen center or the position at the arbitrary angle of screen.
Step S102, obtains the attitudes vibration information of mobile terminal in real time；
At present, being mostly equipped with various attitude transducer in the mobile terminal that market is sold, these attitude transducers are for detecting and obtain mobile terminal attitudes vibration information data.
The attitude of mobile terminal and change thereof can describe with a kind of three-dimensional motion attitude measurement system.As shown in Figure 2, this attitude measurement system (is again yaw angle with course angle, yaw), roll angle (is again roll angle, roll) and the angle of pitch (be again pitch angle, etc. pitch) parameter describes the attitude of object in solid space, is widely used in many fields such as model plane unmanned plane, robot, human motion analysis.Above-mentioned course angle, roll angle and the angle of pitch can be collectively referred to as attitude angle.In the prior art, this three-dimensional motion attitude measurement system is also applied in the attitude detection technology of the mobile terminals such as mobile phone.
Step S103, the attitudes vibration information of current mobile terminal and default cursor according to obtaining move the corresponding relation between mobile terminal attitudes vibration, it is determined that lateral displacement that cursor moves and length travel；
In practical application, it is possible to set cursor in predefined coordinate system and move the corresponding relation between mobile terminal attitudes vibration, it is also possible to set cursor in place coordinate system and move the corresponding relation between mobile terminal attitudes vibration.
For example, it is possible to when using reference attitude, the plane at mobile terminal screen place, in the first three-dimensional coordinate system of pseudo-horizontal plane foundation, sets cursor and moves the corresponding relation between mobile terminal attitudes vibration in advance.Wherein, reference attitude can be that mobile terminal screen has, with horizontal plane, the attitude specifying angle.Wherein, specify angle can be 0 degree (in this case, as shown in Figure 2, first three-dimensional coordinate system overlaps with natural three-dimensional coordinate system), the user that can also be default holds the angle that mobile terminal is comfortable, for instance can be the unspecified angles less than 80 degree such as about 15 degree, about 30 degree, about 45 degree.
In practical application, it is possible to preset reference attitude by user setup, for instance: setting options are provided, obtain user's current pose, namely obtain mobile terminal screen, with horizontal plane, there is angle, using the attitude with this angle as reference attitude.It is of course also possible to not by user setup, directly mobile terminal screen and horizontal plane are had and specify the attitude of angle to be fixedly installed as reference attitude.
In this case, cursor moves the corresponding relation between mobile terminal attitudes vibration, can set that for: in the first coordinate system, first corresponding relation of the roll angle angle of mobile terminal attitudes vibration and light target lateral displacement, and the second corresponding relation of the angle of pitch angle of mobile terminal attitudes vibration and light target length travel.
Or, place coordinate system sets cursor and moves the corresponding relation between mobile terminal attitudes vibration, can be: preset the course angle angle of mobile terminal attitudes vibration and the 3rd corresponding relation of light target lateral displacement and the 4th corresponding relation of the angle of pitch angle of mobile terminal attitudes vibration and light target length travel.
Wherein, the first described corresponding relation can be: the first proportional relationship of the roll angle angle of mobile terminal attitudes vibration and light target lateral displacement, such as: roll angle often increases or reduces some degree, cursor lateral displacement x (x > 0) individual pixel (or x millimeter) to the right or to the left；Described second corresponding relation can be: the second proportional relationship of the angle of pitch angle of mobile terminal attitudes vibration and light target length travel, such as: luffing angle often increases or reduces some degree, cursor length travel y up or down (y > 0) individual pixel (or y millimeter).The 3rd described corresponding relation is: the 3rd proportional relationship of the course angle angle of mobile terminal attitudes vibration and light target lateral displacement, such as: course angle angle often increases or reduces some degree, cursor lateral displacement z (z > 0) individual pixel (or z millimeter) to the right or to the left；Described 4th corresponding relation is: the 4th proportional relationship of the angle of pitch angle of mobile terminal attitudes vibration and light target length travel, the setting of the 4th proportional relationship is similar with the second proportional relationship.
So, it becomes possible to the attitudes vibration information of current mobile terminal and default cursor according to obtaining move the corresponding relation between mobile terminal attitudes vibration, it is determined that lateral displacement that cursor moves and length travel.
Visible, apply the embodiment of the present invention, when mobile terminal attitudes vibration being detected, just can move cursor according to above-mentioned corresponding relation, thus realizing rotating (upset) mobile terminal by user's one hand to control the purpose that cursor moves.Owing to the cursor on the cursor on mobile terminal screen and PPT projection screen is synchronization-moving, so cursor mentioned here moves the cursor both referring on mobile terminal screen, combine with other steps of the embodiment of the present invention, also refer to the cursor on projection screen.

Therefore, described drafting mark function, it is simply that the above-mentioned selection in order to reflect user is intended to.This realization at least can have following two mode:
Judge whether the drafting mark function button preset is pressed, determine that described drafting mark function is opened when drawing mark function button and being pressed, determine that described drafting mark function is closed when drawing mark function button and not being pressed；
Or it is on state or closed mode according to default drafting mark function switch, it is judged that draw whether mark function has turned on.
Above two mode is respectively arranged with pluses and minuses, and this method embodiment can also provide options, makes user can select between two ways, to meet the difference preference of different user.
Step S105, when drawing mark function and not opening, the synchronizing moving cursor on the screen and PPT projection screen of mobile terminal according to the lateral displacement determined and length travel；
In this step, the lateral displacement on mobile terminal screen and length travel first can be marked on according to light, lateral displacement according to default mobile terminal screen and the 6th corresponding relation of the 5th corresponding relation of the lateral displacement of PPT projection screen and the length travel of the length travel of mobile terminal screen and PPT projection screen, calculate light and be marked on lateral displacement and the length travel of PPT projection screen.The the 5th and the 6th corresponding relation in this step, it is possible to be configured according to the ratio of the size of lantern projection's screen Yu the size of mobile terminal.
So, it becomes possible to be marked on the lateral displacement on mobile terminal screen and length travel according to light, and light is marked on lateral displacement and the length travel of PPT projection screen, synchronizing moving cursor on the screen and PPT projection screen of mobile terminal.
Mobile office software popular on the market at present, much already by technology such as " sharing WiFi ", it is achieved that synchronizing moving light target function on the screen and PPT projection screen of mobile terminal.This technology belongs to the prior art that can obtain of those skilled in the art, is not detailed at this.
Step S106, when drawing mark function and having turned on, from the position that cursor is current, synchronizes to draw out track that cursor moves as mark line according to the lateral displacement determined and length travel on the screen and PPT projection screen of mobile terminal；
In this step, the lateral displacement on mobile terminal screen and length travel first can be marked on according to light, according to the 5th described corresponding relation and described the 6th corresponding relation (the concept such as step S105 of the 5th and the 6th corresponding relation), calculate light and be marked on lateral displacement and the length travel of PPT projection screen.On the screen and PPT projection screen of mobile terminal, synchronize to draw out track that cursor moves as mark line according still further to the lateral displacement determined and length travel.
In practical application, drawing before mark line, it is possible to be first smoothed with the corresponding so track of method of least square scheduling algorithm, then actual again drawing.Concrete drawing process, belongs to prior art, no longer describes in detail here.
