Embodiment
The present invention provides a kind of device that prevents touch of key-press by accident.For above and other objects of the present invention, feature, advantage and embodiment can be become apparent, below will elaborate technical advantage of the present invention with a flat computer as preferred embodiment of the present invention with the device that prevents touch of key-press by accident.
Please refer to Fig. 2, the flat computer that Fig. 2 is according to a preferred embodiment of the present invention and is illustrated prevents the calcspar that the signal of touch of key-press by accident device is imported.Among preferred embodiment of the present invention, flat computer has the device 200 that prevents touch of key-press by accident, prevents that the device 200 of touch of key-press by accident from comprising handwriting input assembly 202, button input module 204 and signal supervising device 206.
The first signal control module 202b is used for controlling the transmission of first signal that handwriting input produces.
Among other preferred embodiment of the present invention, handwriting input assembly 202 also comprises signal transmission interface 202c in addition, and wherein signal transmission interface 202c can be RS232 serial transmission interface or universal serial bus (USB) interface.
The second signal control module 204b is used for controlling the transmission of second signal that the button input produced.Among these some bright preferred embodiments, the second signal control module 204b is an embedded control unit.
Among good embodiment of the present invention, whether signal supervising device 206 monitoring handwriting input assemblies 202 produce the mode of first signal, be by oscillogram variation (High-Low) situation of signal supervising device 206 active detecting output signal (Tx) of this signal transmission interface 202c in the unit interval, detect this first signal.
Please refer to Fig. 3, the process flow diagram of detection first signal that Fig. 3 is according to a preferred embodiment of the present invention to be illustrated.
Please refer to step 301, when supposing not have as yet the input of any handwriting input data, the second signal control module 204b can transfer to second signal that button 204a produced among the operating system 209 in addition computing (please refer to step 303).
Please refer to step 305, when button 204a does not produce second signal, the built-in timing of second signal control module 204b circulation, set one time delay T1, among preferred embodiment of the present invention, timing round-robin T1 time delay is set at 500ms.
Please refer to step 307, carrying out the timing circulation simultaneously, signal supervising device 206 can detect the oscillogram situation of change (please refer to step 311) of the output signal (Tx) of signal transmission interface 202c.
Please refer to step 313, when the oscillogram of output signal (Tx) changed to some extent, T1 made zero again with time delay, reseted timing circulation (please refer to step 311).If the oscillogram of output signal (Tx) does not change, then continue to carry out original timing circulation.
When the oscillogram of output signal (Tx) changes to some extent, represent handwriting input assembly 202 carrying out handwriting input, timing circulation can be carried out continuously, makes the second signal control module 204b second signal that handwriting input assembly 204 produced can't be transferred among the operating system 209 in addition computing.
Another judges whether handwriting input assembly 202 produces the mode of first signal, be when whether handwriting input assembly 202 has first signal of generation, the first signal control module 202b initiatively sends the 3rd signal, 206 of signal supervising devices are passive reception the 3rd signals, judge whether handwriting input assembly 202 produces first signal.When first signal produces, stop second signal is transferred among the operating system 209 in addition computing by the signal supervising device 206 order second signal control module 204b.
In addition, the present invention proposes a kind of method that is used for preventing touch of key-press by accident when carrying out handwriting input on flat computer.
Please refer to Fig. 4, Fig. 4 is the process flow diagram that is used for preventing the method for touch of key-press by accident when carrying out handwriting input according to this bright formula that preferred embodiment is painted a kind of on flat computer.At first, provide handwriting input assembly, button input module and signal supervising device (please refer to step 401).
Wherein, the handwriting input assembly has digiboard, and first signal that is used for handwriting input is produced transfers to operating system and carries out computing; The button input module is used for that second signal that the button input is produced is sent to this operating system and carries out computing.
Please refer to step 403, then on digiboard, carry out handwriting input, make the handwriting input assembly export first signal, and first signal is transferred to operating system carry out computing; And
Please refer to step 405, use the signal supervising device to monitor first signal, when the signal supervising device detects first signal, promptly stop the button input module to transmit second signal to operating system (please refer to step 407).Because handwriting input assembly, button input module and signal supervising device have been specified among the preferred embodiment of this instructions, are not being given unnecessary details at this.
According to above-described preferred embodiment, technical characterictic of the present invention provides a kind of device that prevents touch of key-press by accident of flat computer, monitor the signal that is produced by the handwriting input assembly by the signal supervising device, when the signal that is produced when the handwriting input assembly produces, the signal supervising device promptly impels the button input module, stop the signal that the button input module is produced is transferred to operating system, use preventing from the handwriting input process, additionally to import unexpected signal because of touch of key-press by accident.
Though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; those skilled in the art can be used for a variety of modifications and variations under the premise without departing from the spirit and scope of the present invention, so protection scope of the present invention is as the criterion with claim of the present invention.
