本发明是有关于一种触控板侦测触控动作的方法，特别是指一种触控板侦测多指触的方法。The present invention relates to a method for detecting touch motions on a touch panel, in particular to a method for detecting multi-finger touches on a touch panel.
背景技术Background technique
依目前日益复杂的多媒体系统发展趋势，所具备的功能越来越多，相对的操作接口也越来越复杂，然而更多的功能就意味着需要于装置上设置更多的相关操作按键，但在各系统要求越小越精致的需求下，这些按键并未能全数地增设于系统上；故现今的相关开发业者便运用触控板技术，来节省多数操作按键所需空间。According to the current development trend of increasingly complex multimedia systems, there are more and more functions, and the corresponding operation interface is becoming more and more complex. However, more functions mean that more related operation buttons need to be set on the device, but Under the requirement of each system to be smaller and more delicate, these buttons cannot be added to the system completely; therefore, relevant developers use touch panel technology to save the space required for most of the operation buttons.
简而言之，触控板是一种可供使用者利用手指或其它物体(如触控笔)，在其面板上直接触击滑动或是以手势替代按键以控制显示屏上光标移动的输入装置，再加上触控板轻薄的优势，故时常将之结合于笔记型计算机、个人数字助理(PDA)、数字播放器，或其它仅具有限设置空间的电子装置上。In short, a touchpad is an input that allows users to use fingers or other objects (such as a stylus) to directly touch and slide on its panel or use gestures instead of buttons to control the movement of the cursor on the display. device, coupled with the advantage of the touchpad being thin and light, it is often combined with a notebook computer, a personal digital assistant (PDA), a digital player, or other electronic devices that only have limited installation space.
然而，藉由传统的触控板侦测单一指触的触击、移动以及离开等手势指令之装置，于现今电子产品之运用上已不敷使用；因此，相关业者于近些年来亦研发出针对触控板如何判别多指触指令的技术方法，如美国专利案第5825352号之「在一触控板上之仿真鼠标按键及运作的多指触感测方法」(Multiple fingercontact sensing method for emulating mouse buttons andmouse operations on a touch sensor pad)中，即揭露出一种利用侦测触控板感应量之波形来判别手指之碰触的方法。如图1所示，该方法是先预设一最大门坎值10及一最小临界值20，再藉由侦测其触控板1之扫描在线所产生的电容或电阻变化，并判断所形成的感应量波形101之波峰是否不小于前述之最大门坎值10，若其中一扫描在线仅有一感应量波形101且不小于最大门坎值10时，则判定为一手指触；若此扫描在线形成有二感应量波形101、102时，除须先判断此二波形101、102之波峰是否分别不小于前述之最大门坎值10，若仅一感应量波形符合，仍旧判定为一手指触，若此二波形101、102之波峰皆不小于最大门坎值10时，再继续检查此二波形101、102之间所形成的波谷是否不大于前述之最小临界值20，若是，才判定为二独立之手指触。However, devices that detect single-finger gesture commands such as touch, move, and leave by using a traditional touchpad are not enough for the application of current electronic products; therefore, related companies have also developed in recent years For the technical method of how to discriminate multi-finger touch commands on the touch panel, such as the "Multiple finger contact sensing method for emulating mouse button on a touch panel and the multi-finger touch sensing method for emulating mouse button operation" in U.S. Patent No. 5,825,352 buttons and mouse operations on a touch sensor pad), which discloses a method of detecting the touch of a finger by detecting the waveform of the sensing value of the touch pad. As shown in Figure 1, the method is to preset a
但是，如图2所示，上述所揭露之触控板1针对指触之判别技术，却很容易因触控板1受到噪声干扰而造成误判，特别是当此噪声之讯号波形100亦大于一用来判定是否为指触的最大门坎值10时，即会被误判为一指触，也就是图1中，实际仅有一根手指11之触压，却因噪声之干扰，而会被误判为二根手指之触压；因此，如何改善触控板1之侦测方式，以有效防止噪声干扰所导致之误判，便成为相关业者所欲努力研究的方向。However, as shown in FIG. 2 , the

实施方式Implementation
有关本发明之前述及其它技术内容、特点与功效，在以下配合参考图式之二较佳实施例的详细说明中，将可清楚的呈现。The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the second preferred embodiment with reference to the drawings.
在本发明被详细描述之前，要注意的是，在以下的说明内容中，类似的组件是以相同的编号来表示。Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same numerals.
参阅图3、图4及图5，是本发明触控板侦测多指触的方法之第一较佳实施例，该触控板4可为电容式、电阻式或利用电、光波、音波等感应式触控板4，并包括复数扫描线40，该方法包含以下步骤：Referring to Fig. 3, Fig. 4 and Fig. 5, it is the first preferred embodiment of the method for detecting multi-finger touch on the touch panel of the present invention. Equal
首先，如步骤21所示，扫描该等扫描线40。First, as shown in
其次，如步骤22所示，检查各该扫描线40是否产生复数大于一门坎值60的感应值61，若是，则进行步骤23，例如图4中之二扫描线41、42的感应值61皆大于该门坎值60。在本较佳实施例中，所述之感应值61在一般设计上均非实际量测电容值、电阻值、电感值，而会转换成等效电路、量测电压、电流...等各种方式，由于此非本发明之特征着重处，故在此不予赘述；而于该触控板4上所进行之扫描线40的扫描方式，是以循序的方式针对该等扫描线40逐条地侦测扫描，如先扫描第奇数条之扫描线40，再扫描第偶数条之扫描线40，或是全数扫描线40全面且同时地接受侦测扫描，故此为一般具有相关领域背景者所易于变化转用，因此并不应以该较佳实施例中所揭露者为限。Next, as shown in
另须补充说明的是，在此步骤22中，若各该扫描线40无检查出大于该门坎值60之感应值61时，则返回步骤21，继续扫描该等扫描线40。然而，在此所提及的门坎值60，是针对使用者之手指71触碰该触控板4上，其所触碰位置之感应量(电压、电流等)所产生之改变值，进行量测、平均并依评估所求得的一种参考设定值。It should be added that in
然后，如步骤23所示，检查这些感应值61大于该门坎值60的扫描线40中是否至少有两条扫描线40相邻。Then, as shown in
若上述判断为“是”的话，则如步骤25所示，则找出对应的至少一扫描线群组45，并依照该群组45数量，判定出该等扫描线40上具有相对应该群组45数量之参考手指触46，并进行步骤26；例如图4中之一扫描线41的感应值61大于该门坎值60，而相邻该扫描线41的另一扫描线42之感应值61也大于该门坎值60，则此就代表找出一个群组45；又若在这些扫描线40上共找到三组各分别具有至少两条相邻之扫描线40具有大于该门坎值60的感应值61时，即代表形成有三个群组45，也就是具有三根参考手指触46。If the above judgment is "yes", as shown in
值得一提的是，若于进行上述之步骤23的检查时，发现那些感应值61大于该门坎值60的扫描线40皆互不相邻时，则将于该等扫描线40上所产生之感应值61判定为如图4之步骤24中所示的噪声400；也就是说本实施例是以侦测扫描线40群组的概念来判断触控板4是否被触压，此原理之应用是由于一般人之手指71在触压触控板4时，均会于该触控板4上形成一面积的压触，也就是至少会同时按压二条以上相邻之扫描线40，使被按压之该等(一群)相邻的扫描线40产生电容或电阻电感上之变化，因此，在本较佳实施例中，若判读出此并非是一实体的手指71指触，而是由一噪声400造成时，本发明将进而把此噪声400忽视且滤除，并再回归到步骤21，持续进行扫描该等扫描线40。It is worth mentioning that if it is found that those scanning
接着，如步骤26所示，检查该参考手指触46内所产生感应值61之扫描线40数量是否不大于一参考值，若是，则各该参考手指触46即为真实手指触47，若否，则每一参考手指触46包括复数真实手指触47。Then, as shown in
在此再针对步骤26作进一步说明，在本较佳实施例中，即使是如图6所示之两根紧靠的手指71在本触控板4上触压时，依照上述步骤21至步骤25之判别方式，仅能界定出一根参考手指触46(也就是一个群组45)，但藉由步骤26，即可再将每一参考手指触46进行更深入之剖析，例如经测定，一般人的真实手指71通常会压触的扫描线40数量不超过3条时，及设定上述之参考值为三，因此，当侦测到一参考手指触46内所产生感应值61之扫描线40数量超过三时，即可分析出该参考手指触46内含超过一根之真实手指触47。
最后，如步骤27所示，根据所判定之各该真实手指触47内的感应值61求出各重心位置48，并分别标示每一重心位置48为一手指触源。在本较佳实施例中，所提及之重心位置48的求得方法，是先对各扫描线40进行权重标示，之后，再分别乘上每一群组内具有合于门坎值之感应值的扫描线40上所产生之感应变化量(如电流、电压等变化量)并于相加后再除以所有感应变化量之总和，如此触控板4上依序具有编号1到8之扫描线40，且其权重亦为1到8而这些扫描线40之其中在一群组45内仅有编号2及3之扫描线40上有电容之变化，且感应变化值皆为0.5时，则其重心位置48即为(2×0.5+3×0.5)/(0.5+0.5)＝2.5，因此所求得之重心位置48(也就是前述之手指触源)即为2.5处，就是在编号2及编号3之扫描线40之中间，然而于实际应用上，也可视为是以各具有大于该门坎值60之感应值61且又相邻的扫描线40之坐标位置相加后，再简单地利用求算数平均数的方式求得或其它计算方式，故不应局限于本实施例之说明。Finally, as shown in
参阅图7、图8、图9及图10，是本发明触控板侦测多指触的方法之第二较佳实施利，其所运用的原理及架构大致与该第一较佳实施例所述之方法相同，相同之处不再赘述，其不同之处在于，于该触控板4上之扫描线是以二维的方式设置，也就是说，本较佳实施例之触控板4，包括复数第一扫描线402及复数与该等第一扫描线402交错的第二扫描线401，该方法包含以下步骤：Referring to Fig. 7, Fig. 8, Fig. 9 and Fig. 10, it is the second preferred implementation benefit of the method for detecting multi-finger touch on the touch panel of the present invention, and the principle and structure it uses are roughly the same as the first preferred embodiment The methods described are the same, and the same parts will not be repeated. The difference is that the scanning lines on the
首先，如步骤301所示，扫描该等第一扫描线402及第二扫描线401。First, as shown in
值得一提的是，上述之第一扫描线402或第二扫描线401不一定皆各自平行，且第一扫描线402与第二扫描线401间之交错可相互垂直或不垂直皆可，此乃因于实际应用上，各式触控板4会有其不同的形状变化所致。It is worth mentioning that the above-mentioned
其次，如步骤302所示，检查该等第一扫描线402是否产生复数大于一门坎值60的感应值61，若是，则进行步骤33；若扫描各该等第一扫描线402无检查出大于该门坎值60之感应值61时，则返回步骤31，继续扫描该等第一、二扫描线402、401。Next, as shown in
然后，如步骤303所示，检查该等感应值61大于该门坎值60的第一扫描线402中是否有至少两条相邻。Then, as shown in
若步骤303之判断结果为“否”，则如步骤304所示，此感应值61判定为噪声400。If the determination result of
而当步骤303之判断结果为“是”，则如步骤305所示，找出对应的至少一扫描线第一群组49，如图8的第一扫描线402中之编号41及42两条所示，此即界定出二个第一群组49。And when the judgment result of
再进行步骤307，检查该等第二扫描线401是否产生复数大于一门坎值60的感应值61。Then go to step 307 to check whether the
若步骤307之判断结果为“否”，则如步骤306所示，此感应值61也判定为噪声400。If the judgment result of
而当步骤307之判断结果为“是”，则进行步骤309，再继续检查该等感应值61大于该门坎值60的第二扫描线401中是否有至少两条相邻。And when the judgment result of
若步骤309之判断结果为“否”，则如步骤308所示，判定于该等第一、二扫描线402、401上所产生之感应值61为噪声400。If the judgment result of
而当步骤309之判断结果为“是”，则如步骤310所示，找出对应的至少一扫描线第二群组50，如图7的第二扫描线401中之编号43及44两条所示，此即界定出一个第二群组50。And when the judgment result of
再来，如步骤311所示，比较该第一、二群组49、50之数量是否相等，若是，则判定于该等第一扫描线402及第二扫描线401上共具有相对应该第一群组49数量之参考手指触46，若否，则以数量较少之群组数为所判定之参考手指触46。例如，当在该等第一扫描线402上界定出二个第一群组49，但是在该等第二扫描线401上只界定出一个第二群组50时，由于此时第二群组50数量小于第一群组49数量，因此仅能判定出一根参考手指触46。Next, as shown in step 311, it is compared whether the numbers of the first and
接着，如步骤312所示，检查该参考手指触46内所产生感应值61之第一、二扫描线402、401数量是否不大于一参考值，若是，则各该参考手指触46即为真实手指触47，若否，则每一参考手指触46包括复数真实手指触47。在本较佳实施例中，参考手指触46与真实手指触47之数目上之判别方式亦如前述之第一较佳实施例中的步骤26所述，故谅此不再赘述。Then, as shown in step 312, check whether the number of the first and
最后，如步骤313所示，根据所判定之各该真实手指触48内的感应值61求出各重心位置48，并分别标示每一重心位置为一手指触源。在本较佳实施例中，重心位置48之求得可参照前述之第一较佳实施例中于步骤27所述之相关计算说明。Finally, as shown in step 313, each center of
此外，我们亦可以将前述之第一、二较佳实施例所提之技术特征，应用于现行触控板4的延伸功能上，如滤除噪声400并判断出确实的手指71压触后，再利用上述之求重心位置的方式，而将所感测到的使用者手指71所在位置送交至一判别装置(图未示)，再利用该判别装置来进一步地侦测使用者之手指71的手势，以决定是否接收或忽略此手势动作，并可根据所接收到的手势送出时间差，来判读此为连续动作或是两个单独的手势。由于在此所述及之手势判断非为本发明之技术重点，且亦为熟悉此相关技术领域之人士周知，故于此不再针对其运用原理做更深入的说明。In addition, we can also apply the above-mentioned technical features mentioned in the first and second preferred embodiments to the extended function of the
归纳上述，本发明触控板侦测多指触的方法，藉由设定该门坎值60，并与之比对手指71在该触控板4上，是否有二条以上相邻之扫描线40所产生之感应值61大于该门坎值60，来判定于该触控板4上所产生之感应值61是否为由手指71产生，或只是噪声400，以有效避免因噪声400干扰所导致之误判，达成正确判断手指71于该触控板4上之状态，故确实能够达到本发明之目的。To sum up the above, the method for detecting multi-finger touch on the touch panel of the present invention, by setting the
