技术领域technical field
本发明涉及触控技术领域，尤其涉及对象状态判断方法以及触控装置。The invention relates to the field of touch technology, in particular to a method for judging an object state and a touch device.
背景技术Background technique
现代生活中，触控鼠标逐渐普及而有取代掉按键式鼠标的趋势。然而，触控鼠标在某些状况下可能会有误判手指状态的情况。In modern life, the touch mouse is gradually becoming popular and tends to replace the push-button mouse. However, the touch mouse may misjudge the state of the finger under certain conditions.
图1至图4绘示了习知技术中手指在触控鼠标上向触控鼠标前端滑动的示意图。在图1至图4中，下图所示的感应区的长度对应于上图虚线L左侧的手指长度，亦即手指F即使未接触感应表面但距离感应表面一定距离内，亦会反应在感应区长度上。在图1至图4中，感应区103、203、303、403代表了手指与触控鼠标100的感应表面101的相对状态，当手指F的任一部份越贴近感应表面101，感应区103的相对部份就会有更大的接触感应量(例如亮度或电容值变化量)。在图标中以斜线较密的区域来表示。当感应表面101所使用是电容/电阻或其他利用感应矩阵的感测方式时，感应区103所表示可以是多个感应像素的集合，例如是接触感应量超过一门坎值的相邻像素集合。而当感应表面101所使用是光学/红外线或其他非利用感应矩阵而是直接以接触感应量在不同维度的分布去计算坐标位置的感测方式时，感应区103所表示可以是二维感应量变化所交集计算出的感应区域。也就是说，接触感应量可以是像素集合的像素数量/感应区域面积，或者在像素集合/感应区域中对应的感应值加权总合/平均。FIG. 1 to FIG. 4 are schematic diagrams of fingers sliding on the touch mouse toward the front end of the touch mouse in the prior art. In Figures 1 to 4, the length of the sensing area shown in the lower figure corresponds to the length of the finger on the left side of the dotted line L in the upper figure, that is, even if the finger F does not touch the sensing surface but is within a certain distance from the sensing surface, it will respond length of the sensing zone. In FIGS. 1 to 4, the sensing areas 103, 203, 303, and 403 represent the relative state between the finger and the sensing surface 101 of the touch mouse 100. When any part of the finger F is closer to the sensing surface 101, the sensing area 103 The relative part will have a greater touch sensitivity (such as brightness or capacitance value change). In the icon, it is represented by an area with denser slashes. When the sensing surface 101 uses capacitive/resistive or other sensing methods using a sensing matrix, the sensing region 103 may represent a set of multiple sensing pixels, for example, a set of adjacent pixels whose touch sensing value exceeds a threshold. And when the sensing surface 101 uses optical/infrared rays or other sensing methods that do not use the sensing matrix but directly use the distribution of the contact sensing amount in different dimensions to calculate the coordinate position, the sensing area 103 can be a two-dimensional sensing amount Change the sensing area calculated by the intersection. That is to say, the touch sensing value may be the number of pixels in the pixel set/the area of the sensing area, or the weighted sum/average of the corresponding sensing values in the pixel set/sensing area.
在图1中，手指F呈现欲向触控鼠标100的前端滑动的状态，手指F与感应表面101接触的部份只有第一节手指f1的一小部份。在此状态下，感应区103的感应长度会较短且第一节手指f1接触感应表面101部份且感应区203前端(对应第一节手指f1)的接触感应量会大于后端的接触感应量。而在图2中的状态下，手指F已经往前滑动了一点距离，如此第一节手指f1会有更多部份接近感应表面101。在此情况下，感应区203的感应长度会较图1长，且感应区203前端(对应第一节手指f1)的接触感应量会大于后端的接触感应量(斜线较密处)且指尖最前端可能未完全接触感应表面101，因此其接触感应量可能较小。In FIG. 1 , the finger F is in a state of sliding toward the front end of the touch mouse 100 , and the portion of the finger F in contact with the sensing surface 101 is only a small part of the first finger f1 . In this state, the sensing length of the sensing area 103 will be shorter and the first finger f1 touches part of the sensing surface 101, and the touch sensing amount at the front end of the sensing area 203 (corresponding to the first finger f1) will be greater than the touch sensing amount at the rear end . However, in the state shown in FIG. 2 , the finger F has slid forward for a little distance, so more parts of the first finger f1 will approach the sensing surface 101 . In this case, the sensing length of the sensing area 203 will be longer than that in FIG. The front end of the tip may not fully touch the sensing surface 101 , so its contact sensitivity may be small.
而在图3中，手指F又再往前滑动使得第一节手指f1和第二节手指f2的部份几乎平贴在感应表面101上。因此图3中感应区303的感应长度会比图2长，而且这种状态下因为第二节手指f2比起第一节手指f1更加的平贴在感应表面101上，因此感应区303相对应第二节手指f2的部份会有较大的接触感应量(中间及后端斜线较密处)。In FIG. 3 , the finger F slides forward again so that parts of the first finger f1 and the second finger f2 are almost flat against the sensing surface 101 . Therefore, the sensing length of the sensing area 303 in Figure 3 will be longer than that of Figure 2, and in this state, because the second finger f2 is more flat on the sensing surface 101 than the first finger f1, the sensing area 303 corresponds to The part of the second finger f2 will have a larger touch sensitivity (where the middle and rear slash lines are denser).
在图4中，因为手指F已完成往前滑动的动作，第一节手指f1可能会翘起而仅留下第二节手指f2平贴在感应表面101上，因此感应区403的前端会具有较小的接触感应量，而感应区403的后端(对应第二节手指f2)会具有较大的接触感应量。In FIG. 4 , because the finger F has finished sliding forward, the first finger f1 may lift up leaving only the second finger f2 flat on the sensing surface 101, so the front end of the sensing area 403 will have The amount of touch sensitivity is relatively small, while the rear end of the sensing area 403 (corresponding to the second finger f2) has a relatively large amount of touch sensitivity.
然而，在图3至图4的过程中，可能产生手指状态误判的状况。详细言之，在图4中，手指F的第一节手指f1已离开感应表面101，表示使用者并不打算产生控制动作。但在图4中第二节手指f2产生的接触感应量占了较大的比例。因此手指F与感应表面101接触部份的重心会往后退，触控鼠标100可能做出手指在往鼠标后端移动的错误判断。而手指欲自鼠标前端往鼠标后端移动时，其动作与前述动作相反，因此在图4至图3的过程中亦可能产生手指状态的错误判断。However, in the process of FIG. 3 to FIG. 4 , misjudgment of the finger state may occur. In detail, in FIG. 4 , the first finger f1 of the finger F has left the sensing surface 101 , indicating that the user does not intend to perform a control action. But in Fig. 4, the touch sensing quantity generated by the second finger f2 accounts for a larger proportion. Therefore, the center of gravity of the portion of the finger F in contact with the sensing surface 101 will recede, and the touch mouse 100 may make a wrong judgment that the finger is moving toward the rear end of the mouse. When the finger intends to move from the front end of the mouse to the rear end of the mouse, its action is opposite to the above-mentioned action. Therefore, in the process of FIGS.
以上的状况在触控鼠标具有弯曲的感应表面时会特别明显，相关领域提出了感应表面较为平坦的触控鼠标欲解决这样的问题。然而具平坦感应表面的触控鼠标较不符合人体工学，用户在使用时可能会觉得较不舒适。The above situation is particularly obvious when the touch mouse has a curved sensing surface, and related fields propose a touch mouse with a relatively flat sensing surface to solve such problems. However, a touch mouse with a flat sensing surface is less ergonomic, and users may feel less comfortable when using it.

具体实施方式Detailed ways
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
图5至图8绘示了根据本发明一实施例的对象状态判断方法的示意图。图5至图8中手指的状态分别对应前述的图1至图4，因此可一并参考图1至图4的描述来了解图5至图8中手指所呈现的状态。同样的在图5至图8中，下图所示的感应区的长度对应于上图虚线L左侧的手指长度，亦即手指F即使未接触感应表面但距离感应表面一定距离内，亦会反应在感应区长度上。在此实施例中，感应区503、603、703、803会被区分成一前段区域Rf以及一中段区域Rm。在一实施例中，前段区域Rf包含指尖，中段区域Rm包含指尖靠近其它指节的部分及/或是手指的其他指节的至少一部份。接着会去计算前段区域Rf的前段接触感应量S_Rf以及中段区域Rm的中段接触感应量S_Rm，并计算出两种接触感应量的比例，以决定手指的状态。上述的接触感应量可为亮度或是电容变化量。5 to 8 are schematic diagrams of a method for determining an object state according to an embodiment of the present invention. The states of the fingers in FIGS. 5 to 8 respectively correspond to the aforementioned FIGS. 1 to 4 , so the descriptions of FIGS. 1 to 4 can be referred to to understand the states of the fingers in FIGS. 5 to 8 . Similarly, in Figures 5 to 8, the length of the sensing area shown in the lower figure corresponds to the length of the finger on the left side of the dotted line L in the upper figure, that is, even if the finger F does not touch the sensing surface but is within a certain distance from the sensing surface, it will The response is in the length of the sensing zone. In this embodiment, the sensing regions 503, 603, 703, 803 are divided into a front region Rf and a middle region Rm. In one embodiment, the front region Rf includes the fingertip, and the middle region Rm includes a portion of the fingertip close to other knuckles and/or at least a part of other knuckles of the finger. Next, it calculates the front contact sensing value S_Rf of the front region Rf and the middle contact sensing value S_Rm of the middle region Rm, and calculates the ratio of the two contact sensing values to determine the state of the finger. The above-mentioned touch sensing quantity can be brightness or capacitance variation.
在一实施例中，当接触感应量比例大于一状态临界值时，则判断对象相对于该感应表面为非触控状态，反之若小于状态临界值时，则判断为触控状态。相等时则可依设计需求判断为触控状态和非触控状态其中之一。在一实施例中，感应区503、603、703、803…为电容式触控感应数组所产生，所以接触感应量比例的S_Rm/S_Rf较佳各是一组电容感应值的集合，其中接触感应量比例中的前段接触感应量S_Rf即是前段区域Rf所属像素集合的像素数量，而中段接触感应量S_Rm即是中段区域Rm所属像素集合的像素数量。于另一实施例中，前段接触感应量S_Rf与中段接触感应量S_Rm亦可以代表所属像素集合的感应量信息，例如可以分别是所属像素集合的所有像素的感应量总合或者是平均亮度，以下实施例将前段接触感应量S_Rf与中段接触感应量S_Rm表示为所属像素集合的所有像素的平均感应量，但并不限定。In one embodiment, when the touch sensing amount ratio is greater than a state threshold, it is determined that the object is in a non-touch state relative to the sensing surface, otherwise, if it is smaller than the state threshold, it is determined that it is in a touch state. If they are equal, it can be determined as one of the touch state and the non-touch state according to design requirements. In one embodiment, the sensing areas 503, 603, 703, 803... are generated by a capacitive touch sensing array, so the S_Rm/S_Rf ratio of the touch sensing value is preferably a set of capacitive sensing values, wherein the touch sensing The front touch sensing amount S_Rf in the volume ratio is the number of pixels in the pixel set to which the front area Rf belongs, and the middle touch sensing amount S_Rm is the number of pixels in the pixel set to which the middle area Rm belongs. In another embodiment, the front contact sensing value S_Rf and the middle contact sensing value S_Rm can also represent the sensing value information of the pixel set to which they belong, for example, they can be the sum of the sensing values or the average brightness of all pixels in the pixel set to which they belong, as follows. In the embodiment, the front touch sensing amount S_Rf and the middle touch sensing amount S_Rm are expressed as the average sensing amounts of all pixels of the pixel set, but it is not limited thereto.
详细言之，在图5的状态下，手指F仅指尖接触感应表面101，前段区域Rf与中段区域Rm皆是对应指尖或是接近指尖的区域，整体接触感应量较均匀，因此前段接触感应量S_Rf和中段接触感应量S_Rm较接近，接触感应量比例的值不会太大。而在图6的状况下，前段区域Rf对应的是指尖而中段区域Rm对应的是中间指节，因为手指的指尖较中间指节更靠近感测表面101，前段区域Rf的接触感应量高于中段区域Rm的接触感应量，因此前段接触感应量S_Rf会比中段接触感应量S_Rm来得大，依此图6中，感应区603的接触感应量比例应会比图5中的接触感应量比例来得小。而在图7的状况下，前段区域Rf对应的是指尖而中段区域Rm对应的是中间指节，因为手指的中间指节较指尖更靠近感应表面101，中段区域Rm的接触感应量高于前段区域Rf的接触感应量，因此感应区703的中段接触感应量S_Rm会比前段接触感应量S_Rf来得大，因此感应区703的接触感应量比例会有较大的值。同样的，在图8的状况下，前段区域Rf对应的是指尖而中段区域Rm对应的是中间指节，手指的指尖翘起，手指的中间指节较指尖更靠近感应表面101，中段区域Rm的接触感应量高于前段区域Rf的接触感应量，因此感应区803的中段接触感应量S_Rm亦会比前段接触感应量S_Rf来得大，因此感应区803的接触感应量比例会有较大的值。In detail, in the state shown in FIG. 5 , only the fingertip of the finger F touches the sensing surface 101, the front region Rf and the middle region Rm both correspond to the fingertip or the region close to the fingertip, and the overall contact sensitivity is relatively uniform, so the front region The contact induction amount S_Rf is relatively close to the middle contact induction amount S_Rm, and the value of the contact induction amount ratio will not be too large. In the situation of FIG. 6 , the front region Rf corresponds to the fingertip and the middle region Rm corresponds to the middle phalanx, because the fingertip of the finger is closer to the sensing surface 101 than the middle phalanx, the touch sensitivity of the front region Rf It is higher than the touch sensitivity of the middle region Rm, so the front touch sensitivity S_Rf will be larger than the middle touch sensitivity S_Rm, according to Figure 6, the proportion of the touch sensitivity of the sensing area 603 should be higher than that of Figure 5 The ratio is small. In the situation of FIG. 7, the front region Rf corresponds to the fingertip and the middle region Rm corresponds to the middle knuckle, because the middle knuckle of the finger is closer to the sensing surface 101 than the fingertip, and the touch sensitivity of the middle region Rm is high. For the touch sensitivity of the front region Rf, the middle touch sensitivity S_Rm of the sensing region 703 is larger than the front touch sensitivity S_Rf, so the ratio of the touch sensitivity of the sensing region 703 has a larger value. Similarly, in the situation of FIG. 8 , the front region Rf corresponds to the fingertip and the middle region Rm corresponds to the middle phalanx. The fingertip of the finger is raised, and the middle phalanx of the finger is closer to the sensing surface 101 than the fingertip. The touch sensitivity of the middle region Rm is higher than the touch sensitivity of the front region Rf, so the middle touch sensitivity S_Rm of the sensing area 803 will be larger than the front touch sensitivity S_Rf, so the ratio of the touch sensitivity of the sensing area 803 will be larger. large value.
由图7至图8的变化可知，在某些情况下虽然手指持续往前，但因为鼠标的表面是凸曲面，所以手指的接触影像的重心反而可能会往后(靠近手指底部)。详细言之，由于计算手指的接触位置时，一般是以感测到的手指的接触感应量来计算所感应到接触影像的重心，并以该重心代表该手指的接触位置，由图7至图8的变化可知，当手指持续往前但接触影像的重心却会往后，导致该手指的侦测会产生误判，误认该手指是正往后移动。因此若将接触感应量比例大于一状态临界值的状况设定为一非触控状态，并在判定为非触控状态的时间点的一预定时间周期(亦可为0)内忽略掉该对象对于该感应表面的触控动作，则可以避免掉手指F呈现图7至图8的动作时，或呈现图8至图7的动作时，可能产生的误判。然请留意，亦可将接触感应量比例设定成(的倒数)，并在接触感应量比例小于一状态临界值时，则判断对象相对于该感应表面为非触控状态，反之若大于状态临界值时，则判断为触控状态，此类可达到相同作用的变化，均应在本发明的范围之内。It can be seen from the changes in FIG. 7 to FIG. 8 that in some cases, although the finger continues to move forward, because the surface of the mouse is a convex surface, the center of gravity of the contact image of the finger may be backward (closer to the bottom of the finger) instead. In detail, when calculating the contact position of a finger, the center of gravity of the sensed contact image is generally calculated based on the sensed contact sensitivity of the finger, and the center of gravity represents the contact position of the finger. From FIG. 7 to FIG. 8, it can be seen that when the finger continues to move forward but the center of gravity of the touching image will move backward, the detection of the finger will cause a misjudgment, and it will be mistaken that the finger is moving backward. Therefore, if the situation where the proportion of the touch sensing amount is greater than a state threshold is set as a non-touch state, and the object is ignored within a predetermined time period (or 0) at the time point when it is determined as the non-touch state For the touch action on the sensing surface, possible misjudgment may be avoided when the finger F presents the actions shown in FIGS. 7 to 8 , or when it presents the actions shown in FIGS. 8 to 7 . However, please note that the touch sensing ratio can also be set as the reciprocal of (), and when the touch sensing ratio is less than a state threshold, it is judged that the object is in a non-touch state relative to the sensing surface, otherwise, if it is greater than the state threshold When the critical value is reached, it is judged as a touch state, and such changes that can achieve the same effect should be within the scope of the present invention.
在一实施例中，触控装置为一电容式触控装置，而感应区的接触感应量、前段接触感应量以及该中段接触感应量均为电容变化量。另一实施例中，触控装置为一光学式触控装置，感应区的接触感应量、前段接触感应量以及该中段接触感应量均为亮度。In one embodiment, the touch device is a capacitive touch device, and the touch sensitivity of the sensing area, the front touch sensitivity and the middle touch sensitivity are capacitance variation. In another embodiment, the touch device is an optical touch device, and the touch sensitivity of the sensing area, the front touch sensitivity and the middle touch sensitivity are brightness.
多种方法可用以界定手指的前段区域Rf和中段区域Rm。在一实施例中，若手指的感应长度为h，取感应长度的最前端xh长度做为前段区域Rf，并取前段区域后的yh长度做为中段区域Rm，其中x与y为小于1的正实数，且x加y不大于1。以图9为例，若手指的感应长度为h，取感应长度的最前端h长度做为前段区域Rf，并取前段区域后的h长度做为中段区域Rm。前段区域Rf和中段区域Rm间可以有间隔SP亦可没有间隔SP。Various methods can be used to define the front region Rf and the middle region Rm of the finger. In one embodiment, if the sensing length of the finger is h, the length xh at the front end of the sensing length is taken as the front region Rf, and the length yh behind the front region is taken as the middle region Rm, where x and y are less than 1 A positive real number, and x plus y is not greater than 1. Taking FIG. 9 as an example, if the sensing length of the finger is h, the length h at the front end of the sensing length is taken as the front region Rf, and the length h behind the front region is taken as the middle region Rm. There may or may not be a space SP between the front region Rf and the middle region Rm.
请留意，前述图5的实施例可以xh和yh做为门坎来决定图5的判断机制是否启动。也就是说，于一实施例中，若xh和yh均未超过一临界值h_tip，则直接将感应到的触控均定义为正常状态的触控，而当xh和yh至少其一超过临界值h_tip时，才启动前述计算接触感应量比例以决定是否要忽略触控的机制。Please note that in the aforementioned embodiment of FIG. 5 , xh and yh can be used as thresholds to determine whether the judging mechanism in FIG. 5 is activated. That is to say, in one embodiment, if both xh and yh do not exceed a critical value h_tip, all sensed touches are directly defined as normal touches, and when at least one of xh and yh exceeds a critical value h_tip, the aforementioned mechanism of calculating the ratio of the touch sensing amount to determine whether to ignore the touch is started.
请留意，前述的实施例可运用在手指之外的其他对象以及触控鼠标之外的其他装置，因此图5至图9的实施例可简示为：一种对象状态判断方法，用以判断一对象于一触控装置(ex.100)的一感应表面(ex.101)上的一状态，包含：(a)根据对象在感应表面上产生的一接触感应量计算一感应长度(ex.感应区503、603、703以及803的感应长度)；(b)将感应长度区分成一前段区域(ex.Rf)以及一中段区域(ex.Rm)；(c)计算出前段区域的一前段接触感应量；(d)计算出该中段区域的一中段接触感应量；以及(e)计算出中段接触感应量与该前段接触感应量间的一接触感应量比例以判断对象的一对象状态。Please note that the aforementioned embodiments can be applied to objects other than fingers and devices other than touch mice, so the embodiments shown in FIGS. A state of an object on a sensing surface (ex.101) of a touch device (ex.100), including: (a) calculating a sensing length (ex. Sensing lengths of sensing regions 503, 603, 703 and 803); (b) divide the sensing length into a front region (ex.Rf) and a middle region (ex.Rm); (c) calculate a front contact of the front region sensing quantity; (d) calculating a middle touch sensing quantity of the middle section region; and (e) calculating a touch sensing quantity ratio between the middle touch sensing quantity and the front touch sensing quantity to judge an object state of the object.
图10至图13绘示了根据本发明另一实施例的手指状态侦测方法的示意图。图10至图13中手指的状态分别对应前述的图1至图4，因此可参考图1至图4的描述来了解图10至图13中手指所呈现的状态。在此实施例中，会侦测手指的感应长度并和状态临界长度做比较，并藉以判断手指的状态。在图10和图11的实施例中，感应区1003的感应长度h1和感应区1103的感应长度h2均小于状态临界长度ht，因此会将其判断为触控状态。而在图12的实施例中，感应区1203的感应长度h3大于状态临界长度ht，因此会将其设定成非触控状态。在一实施例中，若判断该对象相对于该感应表面为非触控状态，则在判定为非触控状态的时间点的一预定时间周期内忽略掉该对象对于该感应表面的触控动作。如前所述，误判的状况较可能发生在图12至图13的过程中(手指往触控鼠标前端滑动)，或是发生在图13至图12的过程中(手指往触控鼠标后端滑动)，因此若以这样的机制将图12的状况设定成非触控状态，可有效的避免误判的情况。10 to 13 are schematic diagrams of a finger state detection method according to another embodiment of the present invention. The states of the fingers in FIGS. 10 to 13 respectively correspond to the aforementioned FIGS. 1 to 4 , so reference can be made to the description of FIGS. 1 to 4 to understand the states of the fingers in FIGS. 10 to 13 . In this embodiment, the sensing length of the finger is detected and compared with the state critical length to determine the state of the finger. In the embodiment shown in FIG. 10 and FIG. 11 , the sensing length h1 of the sensing region 1003 and the sensing length h2 of the sensing region 1103 are both smaller than the state critical length ht, so it is determined as a touch state. In the embodiment of FIG. 12 , the sensing length h3 of the sensing region 1203 is greater than the state critical length ht, so it is set to the non-touch state. In one embodiment, if it is determined that the object is in a non-touch state relative to the sensing surface, the touch action of the object on the sensing surface is ignored within a predetermined time period at the time point when the object is determined to be in a non-touch state . As mentioned above, the situation of misjudgment is more likely to occur in the process of Figure 12 to Figure 13 (finger slides to the front of the touch mouse), or in the process of Figure 13 to Figure 12 (finger slides to the front of the touch mouse) end sliding), therefore, if the situation in FIG. 12 is set to a non-touch state by such a mechanism, misjudgment can be effectively avoided.
图13的状况下，感应区1303的感应长度h4有可能大于状态临界长度ht亦有可能小于状态临界长度ht(图13的例子中是大于状态临界长度ht)，因此有可能被判定成触控状态亦有可能被判定成非触控状态。可藉由设定状态临界长度ht的大小来让图13的状况会较易落在触控状态或较易落在非触控状态。或者可改变触控鼠标感应的灵敏度来让图13的状况会较易落在触控状态或较易落在非触控状态。举例来说，若灵敏度设定较大，则手指即使远离感应表面亦有可能被感应到，图13的状况可能会具有较长的感应长度。相反的，若灵敏度设定较小，则手指距离感应表面稍远便不会被感应到，图13的状况可能会具有较短的感应长度。可视各种不同需求来设定状态临界长度ht或触控鼠标感应的灵敏度。图5至图8的实施例可与图10至图10至图13的实施例并用，以获得更精确的判断。In the situation shown in FIG. 13 , the sensing length h4 of the sensing area 1303 may be greater than the state critical length ht or may be smaller than the state critical length ht (the example in FIG. 13 is greater than the state critical length ht), so it may be determined as a touch The state may also be determined as a non-touch state. The situation shown in FIG. 13 can be more likely to be in the touch state or in the non-touch state by setting the size of the state critical length ht. Alternatively, the sensitivity of the touch mouse sensor can be changed to make the situation shown in FIG. 13 more likely to be in the touch state or in the non-touch state. For example, if the sensitivity is set higher, the finger may be sensed even if it is far away from the sensing surface. The situation in FIG. 13 may have a longer sensing length. On the contrary, if the sensitivity setting is small, the finger will not be sensed if it is far away from the sensing surface, and the situation in FIG. 13 may have a short sensing length. Depending on various requirements, the state critical length ht or the sensitivity of touch and mouse sensing can be set. The embodiments in FIGS. 5 to 8 can be used together with the embodiments in FIGS. 10 to 10 to 13 to obtain more accurate judgments.
请留意，前述的实施例可运用在手指之外的其他对象以及触控鼠标之外的其他装置，因此图10至图13的实施例可简示为：.一种对象状态判断方法，用以判断一对象于一触控装置的一感应表面上的一状态，包含：(a)根据该对象在该感应表面上产生的一接触感应量计算一感应长度；以及(b)根据该感应长度与一状态临界长度的关系一判断该对象的一对象状态。还请留意，图10至图13的实施例可与图5至图9的实施例并用，以使得判断更为精确来避免误判的状况。Please note that the foregoing embodiments can be applied to objects other than fingers and other devices other than touch mice, so the embodiments in FIGS. Judging a state of an object on a sensing surface of a touch device includes: (a) calculating a sensing length according to a touch sensing amount generated by the object on the sensing surface; and (b) calculating a sensing length according to the sensing length and A relation of state critical length—judging an object state of the object. Please also note that the embodiments in FIGS. 10 to 13 can be used together with the embodiments in FIGS. 5 to 9 to make the judgment more accurate and avoid misjudgment.
除了前述的实施例外，仍有其他状况可能造成误判手指状态。在图14和图15的例子中，图14绘示了手指F的指尖原本按压在感应表面101，但因为使用者打算让手指往触控鼠标后端滑动，因此会有将手指F提起的动作，在此瞬间由于手指F按压感应表面101的面积减少使得触控鼠标计算出的对象重心前移且手指F尚未往后移动，触控鼠标可能会将此动作误判成手指F往前移动。通常来说，若手指F欲往触控鼠标前端滑动，其感应区面积应该是增加的(例如图5至图6再至图7的状况)。因此，若判断出手指F是往前移动但其感应区面积是减少的，则有可能如图14和图15般的状况，在一实施例中会将判断出手指F是往前移动但其感应区面积是减少的状况断定为非触控状态，并在判定为非触控状态的时间点的一预定时间周期内忽略掉该对象对于该感应表面的触控动作。In addition to the aforementioned embodiments, there are still other conditions that may cause misjudgment of the finger state. In the example of FIG. 14 and FIG. 15 , FIG. 14 shows that the fingertip of the finger F is originally pressed on the sensing surface 101, but because the user intends to slide the finger to the rear end of the touch mouse, the finger F will be lifted. At this moment, because the area of the finger F pressing the sensing surface 101 decreases, the center of gravity of the object calculated by the touch mouse moves forward and the finger F has not moved backward. The touch mouse may misjudge this action as the finger F moving forward . Generally speaking, if the finger F intends to slide towards the front of the touch mouse, the area of its sensing area should increase (for example, the situation in FIG. 5 to FIG. 6 and then to FIG. 7 ). Therefore, if it is judged that the finger F is moving forward but the area of its sensing area is reduced, it may be as shown in Figure 14 and Figure 15. In one embodiment, it will be judged that the finger F is moving forward but its area is reduced. When the area of the sensing area is reduced, it is determined as a non-touch state, and the touch action of the object on the sensing surface is ignored within a predetermined time period at the time point when the sensing area is determined as the non-touch state.
同样的，若手指F欲往触控鼠标后端滑动，其感应区面积应该是减少的(例如图7至图6再至图5的状况)。然而，在图16中，使用者原本仅稍微的按压感应表面101，因此手指F造成的感应区面积较小。但在图17中，使用者较用力的按压感应表面101，因此其手指F造成的感应区面积较大，如此触控鼠标可能会因为计算出对象重心的后移而将其判断成手指F往后滑动。因此，若判断出手指F是往后移动但其感应区面积是增加的，则有可能如图16和图17般的状况，在一实施例中会将判断出手指F是往后移动但其感应区面积是增加的状况断定为非触控状态，并在判定为非触控状态的时间点的一预定时间周期内忽略掉该对象对于该感应表面的触控动作。Similarly, if the finger F intends to slide toward the rear end of the touch mouse, the area of its sensing area should be reduced (for example, the situation in FIG. 7 to FIG. 6 and then to FIG. 5 ). However, in FIG. 16 , the user only slightly presses the sensing surface 101 , so the area of the sensing area caused by the finger F is relatively small. However, in FIG. 17 , the user presses the sensing surface 101 harder, so the area of the sensing area caused by the finger F is larger, so the touch mouse may be judged as the finger F moving backward due to the calculation of the object's center of gravity. Swipe back. Therefore, if it is determined that the finger F is moving backwards but the area of its sensing area is increased, it may be as shown in Figure 16 and Figure 17. In one embodiment, it will be determined that the finger F is moving backwards but its area is increased. If the area of the sensing area is increased, it is determined as a non-touch state, and the touch action of the object on the sensing surface is ignored within a predetermined time period at the time point when the sensing area is determined as the non-touch state.
然请留意，图14至图17的实施例不限制于施行在手指和触控鼠标上，可施行在其他对象和触控装置上。因此图14至图17的动作可简示为：一种对象状态判断方法，用以判断一对象于一触控装置的一感应表面上的一状态，包含：(a)根据对象在该感应表面上产生的一第一接触感应量计算一第一对象区域(例如图5至图8的感应区503-803)；(b)根据对象在该感应表面上产生的一第二接触感应量计算一第二对象区域(例如图5至图8的感应区503-803)；(c)根据第一对象区域以及第二对象区域的位置计算出对象的一对象移动方向；以及(d)根据第一对象区域、第二对象区域的大小以及该对象移动方向的关系判断该对象的对象状态。However, please note that the embodiments shown in FIGS. 14 to 17 are not limited to being implemented on fingers and a touch mouse, and can be implemented on other objects and touch devices. Therefore, the actions in FIGS. 14 to 17 can be simplified as: a method for judging the state of an object, for judging a state of an object on a sensing surface of a touch device, including: (a) according to the state of the object on the sensing surface Calculate a first object area (for example, the sensing area 503-803 of FIG. 5 to FIG. 8 ) by a first touch sensitivity generated on the surface; (b) calculate a second touch sensitivity generated by the object on the sensing surface The second object area (for example, the sensing areas 503-803 in FIGS. 5 to 8); (c) calculate an object moving direction of the object according to the positions of the first object area and the second object area; and (d) calculate an object moving direction according to the first object area The relationship between the object area, the size of the second object area, and the moving direction of the object determines the object state of the object.
其中若该第一对象区域较该第二对象区域较早产生，该第一对象区域较该第二对象区域为大，且对象移动方向为朝向触控装置的前端(或是往指尖的方向)，则判断对象为非触控状态(例如图14、图15的实施例)。其中若第一对象区域较第二对象区域较早产生，第一对象区域较该第二对象区域为小，且对象移动方向为朝向触控装置的后端，则判断该对象为非触控状态(或是往手腕的方向)。Wherein if the first object area is generated earlier than the second object area, the first object area is larger than the second object area, and the moving direction of the object is toward the front end of the touch device (or toward the fingertip) ), then it is determined that the object is in a non-touch state (for example, the embodiments of FIG. 14 and FIG. 15 ). Wherein, if the first object area is generated earlier than the second object area, the first object area is smaller than the second object area, and the moving direction of the object is towards the rear end of the touch device, then it is determined that the object is in a non-touch state (or towards the wrist).
