Detailed description of the invention
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the execution flow chart for the method that a kind of conventional teaching of the present invention and electronic white board projection teaching are switched fast.
Specific embodiment
Please emphasis referring to Fig.1 shown in, a kind of conventional teaching of the present invention and electronic white board projection are imparted knowledge to students the method being switched fast Preferred embodiment, which comprises
Step S1, the response time that setting finger touches；
Step S2, using singlehanded at least three finger touch electronic whiteboards, driving obtains the coordinate of each finger touched As initial coordinate；In the specific implementation, after driving gets initial coordinate, initial coordinate can be saved；
Step S3, after reaching the response time, driving obtains the coordinate of each finger of touch again, and will obtain again Coordinate be compared with initial coordinate, if comparison result be identified as unanimously, triggering put out screen operation；If be identified as It is inconsistent, then terminate this touch operation and (removes the data saved, and before this operation is not bounced all, no longer Screen operation is put out in triggering)；
Step S4, singlehanded at least three finger touch electronic whiteboards are reused, driving obtains each finger touched Coordinate is as initial coordinate；In the specific implementation, after driving gets initial coordinate, initial coordinate can be saved；
Step S5, after reaching the response time, driving obtains the coordinate of each finger of touch again, and will obtain again Coordinate be compared with initial coordinate, if comparison result is identified as unanimously, triggering wake-up screen operator；If by recognizing It is set to inconsistent, then terminates this touch operation and (remove the data saved, and before this operation is not bounced all, No longer screen operation is put out in triggering).
It can be seen from the above, by the present invention in that at least three fingers come touch electronic whiteboard, and reaching the response time Afterwards, automatic trigger puts out screen operation, to achieve the effect that put out screen；Carry out touch electronic whiteboard when reusing at least three fingers, And after reaching the response time, automatic trigger wakes up screen operator, to reach normal drop shadow effect.Therefore, through the invention Method come realize conventional teaching and electronic white board projection teaching between being switched fast, valve projection machine can be significantly reduced Time consumption, to can guarantee with sufficient instructional blocks of time.
In the specific implementation, touch point in order to prevent relatively far apart causes false triggering operation (in order to prevent except one hand False triggering caused by other factors except the five fingers), in the step S2 or step S4, the driving obtains each of touch The coordinate of a finger is as initial coordinate specifically:
Setting one is apart from limits value；For example, can be that 4000 (this 4000 refers to electronic whiteboard with set distance limits value On coordinate distance), since everyone finger size and length are different, this can be according to reality apart from limits value Situation is configured；
Driving obtains the coordinate of each finger touched as initial coordinate, calculates the spacing between each initial coordinate Value, and limits value is compared at a distance from setting by the maximum distance values between each initial coordinate, if maximum distance values Less than apart from limits value, then start timing；If maximum distance values are less than apart from limits value, terminate this touch operation.Example Such as, the maximum spacing between calculated each initial coordinate is 3098, set apart from limits value as 4000, due to 3098 small In 4000, therefore, it is necessary to start to carry out timing；For another example, the maximum spacing between calculated each initial coordinate is 4120, if Fixed is 4000 apart from limits value, and since 4120 are greater than 4000, therefore, it is necessary to terminate this touch operation.
In the step S3 or step S5, the coordinate that will be obtained again is compared specifically with initial coordinate Are as follows:
Set a permission moving distance；After being touched on electronic whiteboard due to finger, finger can inevitably occur small It is mobile, it is therefore desirable to set a permission moving distance as the standard compared；
The coordinate obtained again is compared with initial coordinate, and if each coordinate for obtaining again and each initial Deviation between coordinate all within the permission moving distance of setting, then it is consistent to regard as comparison result；If do not set entirely Within fixed permission moving distance, then it is inconsistent to regard as comparison result.
In order to reach better implementation effect, the permission moving distance set is 100, i.e., in the specific implementation, such as Deviation between each coordinate that fruit obtains again and each initial coordinate all within 100, then regards as comparison result one It causes；Otherwise it is assumed that it is inconsistent for comparison result.
In the step S3, screen operation is put out in the triggering specifically:
Driving one full screen window of creation, is filled with blank screen window for the full screen window of creation and brings to Front, and pass through Projector projects to blank screen window on electronic whiteboard, to realize the effect for putting out screen；Meanwhile cursor of mouse is closed, close electricity The touch control operation of sub- blank, coordinate identification when at least three fingers only being kept to touch electronic whiteboard is (i.e. when using at least three When a finger touch electronic whiteboard, the coordinate of each finger of available touch is driven, and if it is other situations, then Touch control operation can not be carried out to electronic whiteboard), at this point, the person of giving lessons can use white board marker to carry out writing behaviour on electronic whiteboard Make.
In the step S5, the triggering wakes up screen operator specifically:
Driving projects to normal teaching window on electronic whiteboard by blank screen close, and by projector, thus real Now normal projection teaching's effect；Meanwhile cursor of mouse is opened, the touch control operation of electronic whiteboard is opened, at this point, the person of giving lessons can Projection teaching is carried out to use electronic whiteboard.
In the step S2 or step S4, using five singlehanded finger touch electronic whiteboards, and singlehanded five After a finger touches on electronic whiteboard, driving will obtain each initial coordinate, for example, five got initial coordinate point Not Wei P1 (25512,11920), P2 (27232,12000), P3 (24960,11136), P4 (24976,10432), P5 (25440, 9472)。
In the step S1, screen effect preferably is put out in order to realize, the triggering set put out the time of screen as 3~6 seconds.
In conclusion the present invention has the advantage that realizing conventional teaching and projection teaching by means of the present invention Between be switched fast, the time consumption of valve projection machine can be significantly reduced, to can guarantee with sufficient instructional blocks of time.
