请参阅图1,图1是依照本发明实施例所绘示的执行第一扫描模式与第二扫描模式的按键扫描方法的流程示意图,并同时参阅图4A至图6以便理解键盘按键扫描的运作流程。图4A是依照本发明另一实施例所绘示键盘可使用的6*21按键矩阵的示意图,图4B是依照本发明另一实施例所绘示第一扫描模式的键盘可使用6*21按键矩阵的示意图,图4C是依照本发明另一实施例所绘示第二扫描模式的键盘可使用6*21按键矩阵的示意图。图5是依照本发明实施例所绘示一键盘输入设备的方块示意图,所述输入设备具有两种扫描模式,分别对应两个按键组。图6是依照本发明另一键盘输入设备的方块示意图,所述输入设备具有三种扫描模式,分别对应三个按键组。
在本实施例中,一种按键扫描方法,适用于一个具有多个按键的输入设备,上述多个按键的其中一部分组成第一按键组10,上述多个按键的其中另一部分组成第二按键组20,且输入设备具有用于扫描上述多个按键的多条扫描线,多条扫描线包括第一主扫描线Sa(1)与多条次扫描线Sb(1)至Sb(N),其中第一主扫描线Sa(1)电性连接至第一按键组10(具体为连接至上述第一按键组10所包含的多个按键),上述多条次扫描线Sb(1)至Sb(N)电性连接至第二按键组20(具体为连接至上述第二按键组20所包含的多个按键)。
上述多个按键的排列形式为矩阵,由R行和C列所组成,其中R与C 为大于等于2的正整数。输入设备除了具有上述多条扫描线外,还具有对应多个按键的多条感应信号线SS。实际操作中,多条扫描线对应矩阵的第1行至第R行设置,多条感应信号线SS对应矩阵的第1列至第C列设置。以一般较多人使用的104键的键盘为例,目前较常使用的矩阵大小为6行*21列(亦即R为6,而C为21),则输入设备可具有6条扫描线以及21条感应信号线。如图4A所示,当输入设备处于一般扫描模式时,轮流触发六条扫描线的顺序为:Row0->Row1->Row2->直到Row5为止,如此当完成一个扫描循环,六条扫描线中每一条均被触发相同的次数。如图4B所示,当输入设备处于电竞扫描模式时,按键扫描电路会将六条扫描线加以分类,设定Row0为第一主扫描线Sa(1),且设定Row1~Row5为五条次扫描线Sb(1)至Sb(5)。举例来说,第一按键组10所包含的多个按键为电竞游戏操作时会经常使用到的特定按键,例如“W”、“A”、“S”、“D”四个英文字母键与“上”、“下”、“左”、“右”四个箭头键,并且这些按键可以是设置在矩阵的第一行Row0(亦即对应前述第一主扫描线Sa(1))。其余电竞游戏操作时不常使用的按键则可以设置在矩阵的第二行至第六行Row1至Row5(亦即对应前述次扫描线Sb(1)至Sb(5))。如稍后图8示意的流程图所描述,当完成一个扫描循环,第一主扫描线Sa(1)的被触发扫描次数高于次扫描线Sb(1)至Sb(5)中每一条的被触发扫描次数。上述多条次扫描线Sb(1)至Sb(N)的列序,亦即Sb(1)至Sb(5),排在第一主扫描线Sa(1)的列序之后,亦即,多条次扫描线Sb(1)至Sb(N)的扫描排列优先级排在第一主扫描线Sa(1)的扫描排列优先级之后。而上述多条感应信号线SS对应矩阵的第一列至第C列设置,也就是对应矩阵的第一列至第二十一列(亦即Col.0至Col.20)设置。
若输入设备同时兼具电竞扫描模式与稍后描述的文书扫描模式,则可参阅图4C来设置第一行与第二行按键。如图4C所示,当输入设备处于文书扫描模式时,按键扫描电路会将六条扫描线加以分类,会设定Row0至Row1为两条主扫描线Sa(1)至Sa(2)(可分别定义为第一主扫描线Sa(1)和第二主 扫描线Sa(2)),且设定Row2至Row5为四条次扫描线Sb(1)至Sb(4);举例来说,第一按键组10包含文书操作时经常使用到的按键,例如至少包含"A至Z"26个英文字母键,并且这些按键可以是设置在矩阵的Row0至Row1上(亦即对应前述两条主扫描线Sa(1)至Sa(2))。其余字处理操作时不常使用的按键则可以设置在矩阵的第三行至第六行Row2至Row5(亦即对应前述次扫描线Sb(1)至Sb(4))。如稍后图9示意的流程图所描述,当完成一个扫描循环,两条主扫描线Sa(1)至Sa(2)中每一条的被触发扫描次数高于次扫描线Sb(1)至Sb(4)中每一条的被触发扫描次数。
如图1所示,本发明实施例可实际应用于具有两种扫描模式的键盘,例如是一般扫描模式(简称为一般模式)与电竞扫描模式(简称为电竞模式)。在步骤S200中,设定扫描模式可以是系统以自动侦测并自动判断的方式执行扫描模式的设定,例如系统侦测到用户开启游戏,此时系统便会自动将扫描模式设定为第一扫描模式(电竞模式)。当然也可以是使用者以手动的方式执行扫描模式的设定。在步骤S210中,在执行第一扫描模式或第二扫描模式的步骤前,所述方法进一步包括判断第一扫描模式与第二扫描模式何者被致能,也就是要执行哪一个模式。第二扫描模式可以是一般模式。在步骤S220中,若第一扫描模式被致能,则执行第一扫描模式,如步骤S221至S223所示。反之,在步骤S230中,若第二扫描模式被致能,则执行第二扫描模式。
接着,请同时参阅图1、图4B与图5,以便理解第一扫描模式的运作流程。在步骤S220中,按键扫描方法包括执行第一扫描模式,第一扫描模式可以是电竞模式,第一按键组10包含电竞操作时经常使用到的多个按键,例如至少包括“W”、“A”、“S”、“D”四个英文字母键,并且这些按键电性连接至第一主扫描线Sa(1),第二按键组20可为除此之外的其他一些按键。在步骤S221中,第一扫描模式包括执行第一扫描程序,第一扫描程序包括触发第一主扫描线Sa(1),并读取多条感应信号线SS的电信号,以判断第一按键组10中是否有按键被触发。在步骤S222中,执行第二扫描程序,第二 扫描程序为触发上述多个次扫描线Sb(1)至Sb(N)的至少其中之一,并读取上述多条感应信号线SS的电信号,以判断第二按键组20中是否有按键被触发。举例来说,以按键的电压准位是否为高准位作为判断此按键是否被按压的例子来说明。若使用者只按压“W”、“A”、“S”、“D”这四个英文字母键的按键。也就是说,在触发第一主扫描线Sa(1)的同时,读取二十一个感应信号线SS的电信号,结果只有第一至第四个感应信号线SS(亦即Col.0至Col.3)的电压准位是高准位,而其余的是低准位,此时便可以判断是“W”、“A”、“S”、“D”这四个英文字母键被按压。换言之,第一扫描程序的阶段便可立即知道是这四个英文字母键被按压,而不用等到第二扫描程序的阶段才得知。因此可以通过软件的方式缩短特定按键的反应时间,提升反应速度。
在步骤S223中,第一扫描程序与第二扫描程序为交替执行,并且每一个次扫描线Sb(1)至Sb(N)至少被触发一次。也就是说,第一扫描程序与第二扫描程序为穿插式、交替式的扫描方式。例如,可以是第一主扫描线Sa(1)搭配一个次扫描线;也可以是第一主扫描线Sa(1)搭配两个次扫描线;或者可以是第一主扫描线Sa(1)搭配三个次扫描线等等。以第一主扫描线Sa(1)搭配一个次扫描线为例子,可以是先触发第一主扫描线Sa(1),接着触发次扫描线Sb(1);然后触发第一主扫描线Sa(1),再接着触发次扫描线Sb(2);紧接着触发第一主扫描线Sa(1),然后触发次扫描线Sb(3);接着触发第一主扫描线Sa(1),然后触发次扫描线Sb(3);再接着触发第一主扫描线Sa(1),紧接着触发次扫描线Sb(4);然后触发第一主扫描线Sa(1),接着触发次扫描线Sb(5),从而完成一个扫描循环,以此类推,再继续地循环下一个扫描循环。假设触发扫描线的时间T为0.5ms,则在第一扫描模式时,第一按键组10的扫描循环为1ms(2T),亦即每1ms会扫描第一按键组10一次;第二按键组20的扫描循环为5ms(10T),亦即每5ms会扫描第二按键组20一次。藉此,大幅度地缩短第一按键组10的扫描循环,同时缩短第一按键组10的按键反应时间。
若第二扫描模式被致能,则执行第二扫描模式,如步骤S230所示。请同时参阅图1与图4A,以便理解第二扫描模式的运作流程。在步骤S231中,第二扫描模式包括交替执行第一扫描程序与第三扫描程序,第三扫描程序包括依序触发上述多个次扫描线Sb(1)至Sb(N),并读取上述多条感应信号线SS的电信号,以判断第二按键组20中是否有按键被触发。也就是说,第一扫描程序与第三扫描程序为穿插式、交替式的扫描方式。例如,先触发第一主扫描线Sa(1),接着可以是依序触发次扫描线Sb(1)至Sb(N),从而完成一个扫描循环,以此类推,再继续地循环下一个扫描循环。
然后,请同时参阅图2、图4C与图6,以便理解第三扫描模式的运作流程。图2是依照本发明实施例所绘示的执行第一扫描模式、第二扫描模式与第三扫描模式的按键扫描方法的流程示意图,亦即电竞模式、一般模式与文书扫描模式(简称文书模式)的实施例。本发明实施例中,前述键盘上的多个按键的其中又一部分组成第三按键组30,且用于扫描上述多个按键的多个扫描线中除了第一主扫描线Sa(1)外,还包括第二主扫描线Sa(2),第二主扫描线Sa(2)电性连接至第三按键组30(具体为连接至上述第三按键组30所包含的多个按键),按键扫描方法进一步包括第三扫描模式,且对应在图1判断第一扫描模式(亦即电竞模式)与第二扫描模式(亦即一般模式)何者被致能的步骤中,图2所示的方法进一步包括判断第三扫描模式是否被致能。若第三扫描模式被致能,则执行第三扫描模式(亦即文书模式)。需注意的是,有关步骤S220至S231的第一扫描模式与第二扫描模式的按键扫描方法已于前述实施例所详加叙述,在此不再赘述。
在步骤S300中,设定扫描模式可以是系统以自动侦测并自动判断的方式执行扫描模式的设定,例如系统侦测到用户开启文字处理软件,此时系统便会自动将扫描模式设定为第三扫描模式。或者可以是用户以手动的方式执行扫描模式的设定。在步骤S310中,按键扫描方法包括判断第一扫描模式、第二扫描模式与第三扫描模式何者被致能。在步骤S340中,若第三扫描模 式被致能,则执行第三扫描模式。
接着,在步骤S341中,第三扫描模式包括执行第一扫描程序(具体执行内容可如步骤S221所示);接着执行第四扫描程序,第四扫描程序包括触发第二主扫描线Sa(2),并读取多条感应信号线SS的电信号,以判断第三按键组30中是否有按键被触发;接着执行第二扫描程序(具体执行内容可如步骤S222所示)。此外,第一扫描程序、第四扫描程序与第二扫描程序为交替执行,并且每一个次扫描线Sb(1)至Sb(N)至少被触发一次。需注意的是,第一按键组10的使用频率比第三按键组30的使用频率高。第二主扫描线Sa(2)的列序排在第一主扫描线Sa(1)的列序之后,上述多个次扫描线Sb(1)至Sb(N)的列序排在第二主扫描线Sa(2)的列序之后。
实际操作中,本发明实施例可实际应用于具有两种扫描模式的键盘,例如是电竞扫描模式(简称为电竞模式)与文书扫描模式(简称为文书模式)。同样的,设定扫描模式可以是系统以自动侦测并自动判断的方式执行扫描模式的设定,例如系统侦测到用户开启游戏,此时系统便会自动将扫描模式设定为第一扫描模式(电竞模式)。当然也可以是使用者以手动的方式执行扫描模式的设定。在执行第一扫描模式或第三扫描模式的步骤前,所述方法进一步包括判断第一扫描模式与第三扫描模式何者被致能,也就是要执行哪一个模式。若第一扫描模式被致能,则执行第一扫描模式;若第三扫描模式被致能,则执行第三扫描模式,第三扫描模式包括:先执行第一扫描程序;接着执行第四扫描程序,第四扫描程序包括触发第二主扫描线Sa(2),并读取多条感应信号线SS的电信号,以判断第三按键组中是否有按键被触发;然后执行第二扫描程序;其中,第一扫描程序、第四扫描程序与第二扫描程序为交替执行,并且每一次扫描线至少被触发一次。
然后,请参阅图3,并同时参阅图4A至图5以便理解按键扫描的运作流程。图3是依照本发明另一实施例所绘示的使用于按键扫描电路的扫描方法的流程示意图,需注意的是,由于使用于按键扫描电路的扫描方法的步骤 流程与按键扫描方法的步骤流程非常相似且有部分是一样的,而按键扫描方法已于前述实施例所详加叙述,在此不再赘述,仅作重点概述。在本实施例中,一种使用于按键扫描电路40的扫描方法,按键扫描电路40可用于扫描第一按键组10与第二按键组20,第一按键组10包含X个优先按键,第二按键组20包含Y个次要按键,按键扫描电路40包括M条主扫描线Sa(1)至Sa(M)、N条次扫描线Sb(1)至Sb(N)与多条感应信号线SS,其中X、Y、M、N为正整数,M条主扫描线Sa(1)至Sa(M)电性连接至X个优先按键,N条次扫描线Sb(1)至Sb(N)电性连接至Y个次要按键,扫描方法包括下列步骤:步骤(1)开始扫描循环,设定主扫描次数j的初始值为0(如步骤S500所示);步骤(2a),判断主扫描次数j是否等于主扫描默认上限值Jmax(如步骤S510所示),其中Jmax为正整数。若是,则执行步骤(3);若否,则执行步骤(2b);步骤(2b),轮流触发M条主扫描线Sa(1)至Sa(M)中的每一条,读取上述多条感应信号线SS的电信号,以侦测X个优先按键中是否有按键被触发(如步骤S530所示);步骤(2c),增加主扫描次数j的值,其中j=j+1(如步骤S531所示),并回到步骤(2a);步骤(3),轮流触发N条次扫描线Sb(1)至Sb(N)的其中P条次扫描线,读取上述多条感应信号线SS的电信号,其中,P条次扫描线为耦接到Y个次要按键中的Q个次要按键,以侦测Q个次要按键中任一个是否被触发,其中P<N,且Q<Y,P、Q为正整数(如步骤S520所示);步骤(4),于扫描循环中,判断N条次扫描线Sb(1)至Sb(N)是否均被触发过(如步骤S521所示),若是,则结束扫描循环(如步骤S540所示),若否,则设定主扫描次数j值为0,并回到步骤(2a)(如步骤S522所示)。
当按键扫描电路40被设定为第一扫描模式时,M等于1(M=1),即输入设备具有一条主扫描线,定义为第一主扫描线Sa(1),X个优先按键均电性连接至第一主扫描线Sa(1)上。于扫描循环中,轮流触发第一主扫描线Sa(1)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:对Sa(1)扫描Jmax次,例 如若Jmax为3时,则连续扫描Sa(1)三次。接着依序扫描次扫描线Sb(1)至Sb(P),然后再对第一条主扫描线Sa(1)扫描Jmax次,接着扫描Sb(1+P)至Sb(2P),以此类推,直到对Sa(1)扫描Jmax次,且接着扫描完P条次扫描线后判断N条次扫描线Sb(1)至Sb(N)均被触发过为止。实际操作中,第一扫描模式可以是电竞模式,X个优先按键至少包含“W”、“A”、“S”、“D”四个英文字母键与“上”、“下”、“左”、“右”四个箭头键。
举例来说,当Jmax=1且P=1时,于扫描循环中,轮流触发第一主扫描线Sa(1)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:Sa(1)->Sb(1)->Sa(1)->Sb(2)->Sa(1)->Sb(3)直到Sa(1)->Sb(N)为止。换言之,先触发第一主扫描线Sa(1),接着触发次扫描线Sb(1),然后触发第一主扫描线Sa(1),再接着触发次扫描线Sb(2),紧接着触发第一主扫描线Sa(1),接着触发次扫描线Sb(3),以此类推,直到触发第一主扫描线Sa(1),接着触发次扫描线Sb(N)为止。
或者例如,当Jmax=1且P=2时,本实施例中,输入设备一共具有6条扫描线,其中包括一条主扫描线和5条次扫描线。于扫描循环中,轮流触发第一主扫描线Sa(1)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:Sa(1)->[Sb(1)->Sb(2)]->Sa(1)->[Sb(3)->Sb(4)]直到->Sa(1)->Sb(5)为止。本实施例中,P等于2,N等于5,P不能够被N整除,在扫描循环内的最后一次扫描时,仅选择N条次扫描线Sb(1)至Sb(N)中尚未被扫描的1条次扫描线Sb(5)进行扫描。实际操作中,还可以于扫描循环中,轮流触发第一主扫描线Sa(1)与N条次扫描线Sb(1)至Sb(N)的顺序还可以是:Sa(1)->[Sb(1)->Sb(2)]->Sa(1)->[Sb(3)->Sb(4)]直到->Sa(1)->[Sb(5)->Sb(1)]为止。即,还可以将N条次扫描线Sb(1)至Sb(N)的循环来作为扫描对象,则可扫描Sb(5)和Sb(1)。
又或者例如,当Jmax=1且P=3时。于扫描循环中,轮流触发第一条主扫描线Sa(1)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:Sa(1)->[Sb(1)->Sb(2)->Sb(3)]->Sa(1)->[Sb(4)->Sb(5)->Sb(6)]直到->Sa(1)->[Sb(N-2)-> Sb(N-1)->Sb(N)]为止。
或者例如,当Jmax=2且P=1时,于扫描循环中,轮流触发第一主扫描线Sa(1)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:[Sa(1)->Sa(1)]->Sb(1)->[Sa(1)->Sa(1)]->Sb(2)直到->[Sa(1)->Sa(1)]->Sb(N)为止。
又或者例如,当Jmax=3且P=1时,于扫描循环中,轮流触发第一主扫描线Sa(1)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:[Sa(1)->Sa(1)->Sa(1)]->Sb(1)->[Sa(1)->Sa(1)->Sa(1)]->Sb(2)直到->[Sa(1)->Sa(1)->Sa(1)]->Sb(N)为止。总的来说,藉由增加对主扫描线Sa(1)的扫描次数,可以大幅度地缩短X个优先按键的反应时间。
当按键扫描电路40被设定为第二扫描模式时,M等于2(M=2),输入设备具有两条主扫描线,分别定义为第一主扫描线Sa(1)和第二主扫描线Sa(2),X个优先按键电性连接至两条主扫描线Sa(1)、Sa(2),于扫描循环中,轮流触发两条主扫描线Sa(1)、Sa(2)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:Sa(1)至Sa(2)循环扫描Jmax次->Sb(1)至Sb(P)->Sa(1)至Sa(2)循环扫描Jmax次->Sb(1+P)至Sb(2P)->Sa(1)至Sa(2)循环扫描Jmax次直到->Sa(1)至Sa(2)循环扫描Jmax次且接着扫描完P条次扫描线后判断N条次扫描线Sb(1)至Sb(N)均被触发过为止。实际操作中,第二扫描模式可以是文书模式,X个优先按键至少包含“A至Z”26个英文字母键。
举例来说,当Jmax=1且P=1时,于扫描循环中,轮流触发两条主扫描线Sa(1)、Sa(2)与N条次扫描线Sb(1)至Sb(N)的顺序可以是:[Sa(1)->Sa(2)]->Sb(1)->[Sa(1)->Sa(2)]->Sb(2)->[Sa(1)->Sa(2)]->Sb(3)直到[Sa(1)->Sa(2)]->Sb(N)为止。换言之,先触发主扫描线Sa(1),接着触发主扫描线Sa(2),然后触发次扫描线Sb(1),再接着触发主扫描线Sa(1),紧接着触发主扫描线Sa(2),接着触发次扫描线Sb(2),然后触发主扫描线Sa(1),再接着触发主扫描线Sa(2),紧接着触发次扫描线Sb(3),以此类推,直到触发第一主扫描线Sa(1),接着触发第二主扫描线Sa(2),然后触发次扫描线Sb(N)为止。总的来说, 藉由增加对主扫描线Sa(1)与Sa(2)的扫描次数,可以大幅度地提升X个优先按键的反应时间。
接下来要说明的是,本发明实施例所提供的按键扫描方法与使用于按键扫描电路的扫描方法是可以执行于输入设备1中,请同时参阅图1至图4C。但本发明并不限制图1至图2的按键扫描方法与图3的使用于按键扫描电路的扫描方法仅能够执行于图5的输入设备1中。需注意的是,由于按键扫描方法与使用于按键扫描电路的扫描方法的步骤流程,已于前述实施例所详加叙述,在此不再赘述,仅作重点概述。
