Abstract
The utility model provides an RF (Radio Frequency) wireless slide demonstration system with a finger sensitive panel and buttons. The RF wireless slide demonstration system is characterized by being provided with a finger sensitive panel, a button module and a PC (Personal Computer) host, wherein the finger sensitive panel and the button module are respectively connected with an RF transmitting remote controller, an RF receiver is connected to a USB (Universal Serial Bus) interface of the PC host, and the PC host is connected with a projector. The RF wireless slide demonstration system with the finger sensitive panel and the buttons has the advantages that a lecturer can operate in a manner of breaking away from the location of the host, the intercommunion and interaction with audiences is facilitated, and the operating experience of the lecturer can be more intuitive and convenient.
Description
Technical field
The utility model belongs to the improvement of a kind of office and tutoring system, relates in particular to the improvement of a kind of magic lantern system.
Background technology
Existing slide show system generally adds projector by main frame and forms, and wherein possibly have the remote control equipment that some have keypress function, possibly not have remote control equipment yet and by the speaker directly with the keyboard and mouse operating host.Be applied to that the business people does project alternative demonstration or expert, the teachers' instruction demonstration is used more.
There is following drawback in existing slide show system:
1, not with the demo system of remote control equipment, the speaker need to switch the demonstration interface, be not easy to the audience closely interactive at operating host by the main frame;
2, the demo system of band button remote control, the user is difficult to locate button or other icons that possesses handoff functionality at demonstration interface.
The utility model content
The utility model provides a kind of wireless slide show of RF system with finger induction panel and button; Its objective is and solve the shortcoming that prior art exists; It is interactive to provide a kind of speaker both to be convenient to the audience, can easily control the slide show system of the information switching at demonstration interface again accurately.
The utility model solves the technical scheme that its technical matters adopted:
Have the wireless slide show of the RF system of finger induction panel and button, it is characterized in that: have finger induction panel and key-press module, the finger induction panel is connected RF emission telepilot respectively with key-press module; Have the PC main frame, connect the RF receiver on the USB interface of PC main frame, the PC main frame connects projector.
The usefulness of technique scheme is:
The utility model can make speaker's Offhost position operate, convenient and audience's exchange and interdynamic, and the operating experience that can make the speaker again is intuitive and convenient more.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model synoptic diagram.
Embodiment
RF is the abbreviation of Radio Frequency, and expression can be radiated the electromagnetic frequency in space, and frequency range is between 300KHz～30GHz.The RF telepilot is the RF remote that occurs at present; Comprise RF emission telepilot and RF receiver; Carry out subsequent treatment after RF emission telepilot is received by the RF receiver through the emission electric wave signal and reach teleaction; Because RF emission remote controllers use is directly need not point to the RF receiver basically to propagated less electric wave, the user has spatially obtained higher dirigibility.
The finger induction panel also is a touch-screen; The branch that capacitive touch screen and resistive touch screen are arranged; Point to the diverse location on the finger induction panel through finger sensing; With selected processing of functional symbol that this position appears to the user, obtain the symbol of confirming that the user selects, the operation that this symbol is corresponding is implemented.
As shown in Figure 1, the utlity model has finger induction panel and key-press module, the finger induction panel is connected with RF emission telepilot through I2C or SPI interface, and key-press module connects RF emission telepilot through universal I/O port; Have the PC main frame, connect the RF receiver on the USB interface of PC main frame, the PC main frame connects projector.
Use is following:
1, the user is with the button of finger touch finger induction panel or key-press module;
2, the touch information of finger induction panel controlled and obtains by RF emission telepilot through I2C or SPI interface;
3, RF emission telepilot obtains the key information of key-press module through the universal I interface,
4, RF emission telepilot will be pointed the touch information of induction panel or the key information of key-press module is launched through self-defining protocol data bag.
5, the RF receiver receives the self-defining protocol data bag of above-mentioned steps 4; Parse the finger induction panel touch information or key-press module key information and this information is converted into mouse device type datagram in the USB HID agreement, pass to the PC main frame through USB interface;
(2), the Windows system of PC main frame will receive the Mouse device data newspaper of USB HID, with the form notice lantern slide application program of mouse Action Events;
(3), the lantern slide application program is upgraded the lantern slide interface according to the mouse Action Events;
(4), projector shows lantern slide interface switching state.
Claims (1)
1. have the wireless slide show of the RF system of finger induction panel and button, it is characterized in that: have finger induction panel and key-press module, the finger induction panel is connected RF emission telepilot respectively with key-press module; Have the PC main frame, connect the RF receiver on the USB interface of PC main frame, the PC main frame connects projector.
