Coordinate set after changing is into mobile terminal according to the screen annotations and comments event monitored, and acquisition is drawn and is stored in the coordinate set of the current screen image on drawing painting canvas, and obtain after coordinate conversion is carried out to this coordinate set; The annotations and comments person's handwriting that current screen image comprises snapshot picture and obtains according to screen annotations and comments event.
In a specific embodiment, for the mobile device of android system (mobile terminal), the specific works process of the embodiment 1 of the system that the long-range annotations and comments that the present invention implements from interactive intelligent tablet computer angle are synchronous can be as described below:
1) interactive intelligent tablet computer transmitting element 510 sends screen picture in real time to mobile device, is intercepted, and save as the image after screenshotss by mobile device;
2) create Android drawing painting canvas (Canvas) by mobile device, any image or person's handwriting can be drawn on drawing painting canvas by the paintbrush set (Paint class); Annotations and comments operation in the embodiment of the present invention is all carried out on Android drawing painting canvas.
3) by mobile device by the Image Rendering after screenshotss on drawing painting canvas, in graphing (onDraw) method of control, call drawing image method (canvas.drawBitmap) drawing image of Android drawing painting canvas, and record the image of current drafting.And sectional drawing to be plotted on drawing painting canvas figure as a setting and can to ensure the display of mobile terminal and the consistent of interactive intelligent tablet computer.
4) when mobile terminal listens to Android screen annotations and comments event, annotations and comments person's handwriting is drawn in movement according to finger, namely in graphing (onDraw) method of control, call curve plotting method (canvasdrawPath) curve plotting of Android drawing painting canvas, and record the person's handwriting of current drafting.Wherein screen annotations and comments event is the operation being different from screen touch event, specifically, can arrange the annotations and comments tool bar or comment button that trigger Postil Function in mobile terminal, when user triggers Postil Function, namely mobile terminal enters monitors Android screen annotations and comments state-event; Screen touch event then without the need to arranging tool bar or the button of triggers touch function on screen, and user can trigger screen touch event by finger touch screen; In addition also can be different or dynamics is different according to time of staff touch screen, pre-set different gesture operations to trigger screen Postil Function or screen touch function.
5) carry out coordinate conversion by the annotations and comments point coordinate set of mobile terminal to annotations and comments event, obtain the coordinate set after changing; Interactive intelligent tablet computer receiving element 520 receives the coordinate set after conversion, and resolution unit 530 is resolved the coordinate set after conversion, and display unit 540 annotates and comments on person's handwriting accordingly according to the coordinate set display after parsing:
In a specific embodiment, the upper left corner that coordinate set is got in mobile terminal is true origin, coordinate set (A after conversion, B) be: by the set of annotations and comments point, each puts the pixel coordinate (x1 in the relative upper left corner, y1) (65535*x1/Xm is converted to, 65535*y1/Ym), wherein Xm refers to the horizontal resolution of mobile terminal screen, and Ym refers to the vertical resolution of mobile terminal screen.
Interactive intelligent tablet computer receiving element 520 receives the coordinate set (A after conversion, B), resolution unit 530 is resolved the coordinate set after conversion, the coordinate set of resolving is (Xn*A/65535, Yn*B/65535), wherein Xn, Yn are the screen resolution that Intelligent flat (giant-screen) is held, and interactive intelligent tablet computer annotates and comments on person's handwriting accordingly according to the coordinate set display after parsing.
In a specific embodiment, interactive intelligent tablet computer can receive the coordinate set (Xn*x1/Xm, Yn*x1/Ym) of mobile terminal conversion, and uses this coordinate set to carry out annotating and commenting on the display of person's handwriting.
In a specific embodiment, interactive intelligent tablet computer can receive the coordinate set (x1, y1) directly sent by mobile terminal, and carries out the display of annotating and commenting on person's handwriting after being resolved to (Xn*x1/Xm, Yn*x1/Ym).
The system embodiment 1 that the long-range annotations and comments that the present invention implements from interactive intelligent tablet computer angle are synchronous, because adopt mobile device remote manipulation interactive intelligent tablet computer to carry out annotations and comments synchronously, ensures that mobile device is consistent with the annotations and comments that interactive intelligent tablet computer shows; Mobile device constantly receives and intercepts the image of interactive intelligent tablet computer transmission, the related datas such as the coordinate set information of annotations and comments are sent to interactive intelligent tablet computer simultaneously, and operated accordingly according to related data by interactive intelligent tablet computer, so the annotations and comments on guarantee mobile device are consistent with the annotations and comments that interactive intelligent tablet computer shows, thus ensure that user can depart from the associative operation (annotations and comments) of interactive intelligent tablet computer realization to screen content, and and audience interaction.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this instructions is recorded.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
