Embodiment
Below in conjunction with accompanying drawing structure of the present invention is done further detailed explanation.
Fig. 1 is the structured flowchart of the electronic blackboard of one embodiment of the invention.Fig. 2 is the structural representation of the touch display screen of Fig. 1.Fig. 3 is the cut-open view of the touch display screen of Fig. 2.
As depicted in figs. 1 and 2; A kind of electronic blackboard that the embodiment of the invention provides; It comprises touch display screen 1 and computer 2, and said touch display screen 1 is connected with the main frame (not shown) of said computer 2, is used for the touch track that acts on the said touch display screen 1 is changed into the main frame that electric signal is transferred to said computer 2; The main frame of said computer 2 is discerned said touch track according to said electric signal, and said touch track is presented on the said touch display screen 1.The electronic blackboard that the embodiment of the invention provides has comprised computer 2, therefore also can realize very various function through the various interface of computer 2, for example:
1, bluetooth receives, and supports the wireless blue tooth microphone to give lessons, Bluetooth transmission courseware and alternative document exchange;
2, network is shared, and connects the campus computer network, the distribution of courseware and shared, and it is convenient to transmit;
3, USB flash disk plug and play: convenient easy-to-use exchange files and courseware calls.
As shown in Figure 3, X axle and Y axle that the touch display screen 1 of present embodiment is provided with display panel 13 have light emitting diode transmitter 15 arranged in a uniform and receiver 14, in correspondence with each other.The display circuit (not shown) is arranged in the housing 11, when touching with finger, pen or any object that can stop light, can block the infrared light beam through this point, can detect the position of touch at the receiver of X axle and Y axle, to judge its coordinate.Can find out that it has the mouse all functions, but more flexible than mouse, not have by space and time and go up control, can be directly advantage such as dialogue face-to-face.In addition, said touch display screen 1 also can be used for the vision signal display image according to the main frame output of said computer 2.If cooperate the software support that is installed on said computer 2 again, electronic blackboard of the present invention more can be accomplished more more rich functions, for example:
1, three-dimensional geometry shows: three-dimensional arbitrarily angled conversion, and the plane, three-dimensional, dynamic geometry figure is supported entirely;
2, Latex word flow, the seamless combination literal, formula etc. also can easily be edited, and need not to switch to computer;
3, colorful writing on the blackboard: polytype lettering pens such as writing brush, pencil are provided, can also draw straight line, figure, and can self-defined ink marks and the attributes such as thickness, color, line style, line cap, line tail and transparency of line;
4, screen annotations and comments: can in arbitrary interface, annotate and comment in real time also and can preserve the annotations and comments content;
5, teaching notes editor: powerful teaching notes editting function and lantern slide playing function is provided;
6, handwriting recognition: easily discern teacher's original handwriting;
7, Figure recognition: can discern various figures;
8, screen blocks: a key hides and recovery electronic blackboard zone.
As stated, electronic blackboard of the present invention can directly use pen or finger on touch display screen 1, to write or note when using, and at this moment it can regard one " blackboard " fully as, and different is not need chalk, and writes color and can arbitrarily change.But; The electronic blackboard of the above embodiment of the present invention can also have other expanded functions, and is for example, as shown in Figure 1; Can also comprise the sensor 4 that is connected with the main frame of said computer 2, said sensor 4 is used for the measurement environment parameter and said environmental parameter is presented at said touch display screen 1.As everyone knows, under some specific environments, environmental parameters such as temperature, humidity may directly have influence on teaching or meeting quality.For example, in the chemical experiment course, quite most experiment parameter requires very harsh, and the variation of temperature or humidity possibly directly influence experimental result, thereby has influence on the height of quality of instruction.The electronic blackboard of the above embodiment of the present invention can easily solve an above-mentioned difficult problem through increasing temperature sensor or humidity sensor, makes electronic blackboard of the present invention to be more suitable for being applied in chemistry or the physics laboratory's teaching by more existing multimedia teaching facility.The same parameter that influences the teaching factor should be not limited to temperature and humidity, and therefore, environmental parameter described in the present invention comprises oxygen and carbon dioxide content, temperature, humidity and/or environmental noise in atmosphere or the enclosure space; Said sensor 4 correspondingly comprises air borne sensor, temperature sensor, humidity sensor and/or sound transducer.
In addition, for abundant teaching, possibly need displaying video to help students understand and memory in case of necessity, traditional method is to accomplish through other extra video equipments, for example projector or TV or the like.But this has increased number of devices undoubtedly, and one increases cost, two operate also extremely loaded down with trivial details and inconvenient.In the present invention, as shown in Figure 1, the main frame of the computer 2 of the electronic blackboard of the embodiment of the invention can comprise video signal input interface 5, and it is configured to gather outer video signal and sends it to computer 2.Wherein said video signal input interface 5 is included as television interface, computer VGA interface or high definition HDMI interface.Like this, electronic blackboard of the present invention just can directly be connected with TV or other audio-visual devices, realizes the various video curricula, for example:
1, animation courseware such as Flash is play, flash demo;
2, video display, all main flow forms are supported in program request;
3, computer model: can accept the computer video input;
4, television mode: play-over TV functions
5, support to connect peripheral audio-visual devices (AV video, SV video, YPBPR, HDMI HD video).
Based on identical thinking; As shown in Figure 1; The electronic blackboard of the embodiment of the invention can also also comprise the audio frequency apparatus that is connected with the main frame of said computer 2; Said audio frequency apparatus comprises audio collecting device 6, audio processing equipment 7 and audio output apparatus, and said audio collecting device 6 is used to gather external audio signal, and said audio processing equipment 7 is used for the said external audio signal of encoding and decoding and sends it to audio output apparatus and said computer 2.The effect of audio collecting device is to gather the person's of giving lessons audio frequency and it is conveyed to the participant through audio processing equipment and audio output apparatus; General microphone can be competent at this work; But consider and give lessons conveniently; In the embodiment of the invention, as shown in Figure 1, said audio collecting device is a Bluetooth audio equipment 6; Said audio processing equipment is a Bluetooth adapter 7; Said audio output apparatus comprises digital power amplifier DDAS 8 and loudspeaker 9.Certainly, also can be by computer 2 direct output audios to audio output apparatus, aided education.For example with completed courseware recording carrying out once more playback, audio file is play, and the electronic blackboard of the embodiment of the invention can be supported all main flow forms, for example mp3, wma, ogg, wav etc.
Certainly, the above is a preferred implementation of the present invention, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also are regarded as protection scope of the present invention.
