Description
技术领域
发明总地涉及便携式计算机,在一个实施方案中,便携式计算机具有宽触摸板。
背景技术
技术的进步使得个人计算机的尺寸在缩减。结果,便携式计算机如笔记本计算机、膝上型计算机和记事本计算机的使用飞速增长。笔记本计算机和记事本计算机的轻便性使用户对他或她的计算机触手可及,这样实际上计算资源总是在手边。图1示出的是典型的具有两个可折叠对半部分的笔记本计算机,显示部件在一个对半部分上,具有输入设备的基座部件在另一个对半部分上。输入设备包括用于输入数据的键盘和操作光标控制的触摸板等。手掌放置区即位于基座部件的上表面而又在键盘下方的区域。它们允许用户在打字时把他或她的手的底部或手掌舒适地放置。大多数结合在便携式计算机中的传统触摸板都以某种方式避免与用户的手发生不必要的接触(例如,在打字时)。这通常通过将触摸板集中在键盘下方并最小化触摸板的尺寸来达到,例如,通过不将触摸板扩展到紧邻触摸板的任一条边形成的手掌放置区。触摸板也下凹进手掌放置平面之下,以便手掌(即意外激活触摸板的最普遍的原因)不会接触到触摸板。
便携式计算机的一个趋势是使它们能替代台式计算机,这需要他们更大,而仍维持它们便携的特点。尤其是包括显示屏的显示部件变得更大,能与台式计算机屏幕的尺寸相比。这导致基座部件的外壳成比例地增加。大基座部件外壳易于容纳标准尺寸的键盘,但正如上面所讨论的,因为不必要激活的高风险以及为手掌放置提供必要的空间,所以触摸板的尺寸仍必须被限制。
此外,为了使较大的便携式计算机适于便携的目的,它们必须仍然相当轻薄。一种减小便携式计算机整体厚度的常用方法是把触摸板装配成与基座部件外壳的上表面(例如手掌放置区)成一平面。但是,这增加了被用户手掌意外轻触的可能性,尤其在打字时。
发明内容
在此描述具有一个或多个输入设备包括键盘和加大或宽的触摸板的便携式计算机的实施方案。便携式计算机包括由铰链部件连接起来的显示部件和基座部件,允许显示部件在打开状态和闭合状态之间变换(即旋转)。显示部件包括显示图像、数据和移动光标的显示屏。设在基座部件上的宽触摸板和键盘允许用户与显示屏互动(如输入数据)。在一个实施方案中,宽触摸板可以是光标控制设备,具有传统计算机鼠标设备的功能,例如对图形用户界面上的对象点击、拖拉、轻点、双击,也可以是更一般的目的,例如对显示屏上图像的滚屏、扫视(panning)、缩放和旋转。宽触摸板延伸至基座部件表面的通常为手掌放置区(例如在基座部件的表面上在用户打字时支持用户手和/或腕的平坦区域)保留的区域。
在一个实施方案中,宽触摸板过滤每个探测到的接触或接触印痕(contact patch),以便接受该接触当作有意的输入命令(例如光标控制命令),或拒绝该接触把它当作无意的(例如当用作手掌放置部分时)。宽触摸板可以过滤多个接触印痕,以便接受触摸板的一个区域中的特定接触印痕而拒绝宽触摸板别处的第二接触印痕。在一个实施方案中,传感器设在键盘和触摸板之间。传感器定义了从基座部件的上表面向上延伸的平面感应区域。传感器探测可能正放在基座部件上的用户的手,手掌部分与部分宽触摸板接触,而手指伸向键盘。当完成这个探测后,就拒绝与触摸板相应部分所做的任何接触,理解为用户无意的接触。可选地,探测伸向键盘的手指可以作为用于判断是否与触摸板接触以及有何含义的多种因素之一而被评估。例如,其他因素可包括与触摸板接触的轮廓、在接触时键盘活动的程度等。这样,除了当输入被解释为用户的有意接触时用作实际发挥作用的触摸板之外,触摸板还可以有效地起到手掌放置部分的作用(例如,用户可有意地将一个或多个手掌或者手或手臂的其他部分置于一部分触摸板上,这被识别为无意的输入)。
在此描述多个其他实施方案,这些实施方案一般涉及具有宽触摸板的便携式计算机,它们基于如手的位置,接受或拒绝触摸板上的接触印痕。

具体实施方式
为了全面理解本发明,在接下去的描述中,提出了众多具体的细节,例如具体的组件、电路、过程等的例子。但对于本领域的技术人员来说应该清楚这些具体细节对实现本发明并不是必需的。另一方面,为了避免使本发明不清楚,对于熟知的组件或方法就不详细描述了。
术语“耦接”在此表示直接连接或通过一个或多个插入组件、结构或元件间接连接。在此使用的术语“在......上”、“在......下”和“在......之间”是指一个组件或元件相对于另一个组件和元件的相对位置。因此,设在另一个组件以上或以下的一个组件可以直接与其他组件接触或有一个或多个插入组件。此外,设在其他组件之间的一个组件可以直接与其他组件接触或有一个或多个插入组件。
下面描述具有加大触摸板的便携式计算机(也被称为笔记本计算机或膝上型计算机)的多个实施方案。触摸板提供输入和常用的光标控制功能,例如点击、拖拉、轻点、滚屏、扫视、旋转和缩放。在本发明的一个实施方案中,触摸板在打字期间对用户的手起到手掌放置的作用。在本发明的另一个实施方案中,触摸板被扩大为沿便携式计算机基座部件的实际宽度方向延伸,一直延伸到手掌放置区中。手掌放置区包括在基座部件顶部的前面的那些区域,键盘位于基座部件上的手掌放置区后。因此,用户平常使用中,手掌放置区比键盘离用户更近,键盘通常邻近将基座部件耦接到显示部件的铰链。典型地,手掌放置区包括左手掌放置区和右手掌放置区,中心部分把这些左右手掌放置区分开。在现有技术的便携式计算机中,该中心部分典型地包括触摸板或其他光标控制设备。便携式计算机的大触摸板的优点包括增大的动态输入范围区域、对触摸板的双手控制以及基于触摸板上的多个手指的高级输入。
在一个实施方案中,当用户并不想激活触摸板时,触摸板有拒绝意外接触的能力(例如,触摸板能区分当用户接触触摸板时是为了有意使用还是仅仅是在打字期间把他或她的手放在触摸板的特定部分)。在一个具体实施方案中,传感器被设在便携式计算机的触摸板和键盘附近来感知用户的手的位置,随后确定接触触摸板是有意的还是无意的。通过认可触摸板上的动作或拒绝动作,触摸板适当地作出响应。因此,通过让打字和光标控制操作无缝地进行,用户就能有效地工作。在一个实施方案中,加大的触摸板/手掌放置区适用于和具有基座和显示部件(例如显示器框架、基座部件外壳)的便携式计算机一起使用,显示器和基座外壳全部或部分使用金属材料制成,尤其是使用如钢、铝、钛或它们的合金。
图2是包括显示部件210和基座部件220的便携式计算机200的一个实施方案的透视图。显示部件210由铰链216耦接到基座部件220,允许显示部件210在打开状态(如图2所示)和闭合状态(未示出)之间变换(即旋转)。显示部件包括显示屏212和相关的视频电路(未示出)。在一个实施方案中,显示屏212可以是液晶显示单元。在替换的实施方案中,显示屏212可以是视频监视器或任何公知的显示设备。显示屏由外框214居中框在显示部件210上。打开时,显示屏212显露在显示部件210上。输入设备包括键盘222、触摸板224和触动按钮226(如“鼠标按钮”),它们设在基座部件220的上表面232上。扬声器260、262也可设在基座部件220的上表面232上。
在一个实施方案中,触摸板224可以是具有传统计算机鼠标功能的输入设备,例如对图形用户界面上的对象点击、拖拉、轻点和双击,也可以是更一般的目的,例如对显示屏212上图像的滚屏、扫视、缩放和旋转。沿键盘222和触动按钮226的触摸板224允许用户与便携式计算机200通信(例如,与显示屏212交互或输入数据)。在一个实施方案中,触摸板在此定义为任何2维平面传感器,能探测一个或多个触摸板表面上的对象(触摸板输入),输出信息有关所述对象的位置、宽度、存在和数量的信息(触摸板输出),输出的方式可被计算机系统解释为生成光标移动,否则认为是用户有意或无意的输入。在一个实施方案中,触摸板224可能是使用电容感应的触摸板。触摸板的表面可包括由绝缘体覆盖的导电金属线网格。当两个导电对象相互接近但不接触时,它们的电场相互作用形成电容。同样,当另一种导电材料如人的手指接触触摸板的表面,就形成电容。
触摸板224的尺寸,尤其是宽度(即平行于键盘222上键的行方向的距离)比传统触摸板更大。在图2所示的实施方案中,触摸板224延伸到基座部件220的表面232上通常保留为手掌放置区(如,用圆圈虚线标记指出的区域252、254)的区域中,但是仍然允许用户把他或她的手掌放在触摸板224的表面上。替换地,除了有传统触摸板功能之外,触摸板224的所有或特定部分可以用作用户的手的手掌放置部分。需要指出在此描述的手掌放置区252、254并非只为打字时用户的手掌而保留,身体的其他部分也可放在手掌放置区252、254。例如在使用期间,用户的肘或前臂可放在基座部件220的任何非键盘部分(例如,当用右手打字时,用左肘或前臂靠着手掌放置部分)。
如下更详细的描述,加大的触摸板224能拒绝无意接触而接受有关输入设备功能性的有意接触(例如光标控制命令)。在一个实施方案中,传感器240被设在键盘222和触摸板224之间。传感器240定义了从上表面232向上延伸的平面传感区域。在一个具体实施方案中,传感器240探测可能正放在基座部件220上的用户的手,手掌一部分接触到一部分触摸板224,手指伸向键盘222。当作出这样的探测时,与触摸板相应部分的任何接触都会被拒绝,那被解释为用户无意的接触。或者,探测伸向键盘222的手指可以作为用于判断是否与触摸板224接触以及有何含义的多种因素中的一种而被评估。例如,其他因素可包括接触触摸板224的轮廓、在接触时键盘活动的程度等。这样,除了当输入被解释为用户的有意接触时正常发挥作用的触摸板功能之外,触摸板224还可有效地起到手掌放置的作用(例如,用户有意地将一个或多个手掌或者手或胳膊的其他部分放在触摸板的一部分上,系统识别出并解释为无意的输入)。图3示出了在上表面232上带有延伸到手掌放置区的触摸板224的便携式计算机200处于打开状态的俯视图。在一个实施方案中,具有特别宽的尺寸的触摸板224分为三个区域:左区域242、中央区域244和右区域246。传感器240被设在键盘222和触摸板224之间,在一个实施方案中,传感器240是具有与触摸板224的宽度基本相同的宽度的传感器带,它设在键盘222和触摸板224之间。触摸板224的三个区域可选择性地激活或停用,这基于特定的接触区域或者由触摸板224感应的“接触印痕”,同时还与探测手部或伸向键盘222的键的手指的传感器240的特定区域有关。在替换实施方案中,只有某一区域(不是全部区域)中的特定接触印痕才能被选择地被接受或拒绝。将认识到传感器240的其他配置也是可能的,例如,传感器240可以是多个传感器,或者不能与触摸板224一起延伸。
图4-6示出了用户使用便携式计算机200的多种可能场景(即手的位置)中的三种以及可能接受或拒绝接触的触摸板224的三个区域的识别操作。图4是典型的用户打字状态,其中左手280和右手282的手指伸展在键盘222上方,两手掌都放在触摸板224的区域上。具体地说,左手280完全放在左区域242,右手282放在右区域246。传感器240探测到左手280手指的伸展并与手指在左区域242的接触关联起来。同样,传感器240将右手282手指和右区域246的接触关联起来。因此,在左区域242和右区域246的接触印痕不认为是任何形式的输入或触摸板操作。用户的手可以舒适地放置在触摸板224的这些区域上,在这种情况下左区域242和右区域246起到手掌放置的作用。相反,触摸板224的中央区域244可以是活动的并对触摸板感应作出响应。
图5示出另一个方案,其中左手280的手指伸展到键盘222的键上方而右手282手指接触触摸板224。在这种情况下,右手282作出的接触是有意的并意味着是激活触摸板的动作(例如点击、拖拉、轻点)。传感器240探测左手280手指的伸展并将这些手指与左区域242上作出的接触关联起来。因此,左区域242上的接触印痕不认为是任何形式的触摸板操作。但是,触摸板224右区域246上的接触印痕被认为是有效的触摸板动作,并以适当的触摸板命令作出响应(例如,拖拉、点击)。用户的左手280可舒适地放置在触摸板224的左区域242上并进行打字,而右手282手指进行触摸板动作。在一个实施方案中,触摸板224的中央区域244也可以是活动的并对触摸板感应作出响应。
图6示出第三种情况,即左手280和右手282都不伸展到键盘222上方。这种手的姿势可能当用户只使用触摸板时出现。在这种情况下,左手280的一部分放在左区域242上,同时右手282手指进行触摸板动作,两手的任何部分都没有伸展到键盘222的上方。右手282手指作出的接触印痕是有意的并意味着是激活触摸板的动作/输入(例如,点击、拖拉、轻点)。左手280作出的接触印痕是无意的。尽管传感器240没有探测到任何东西,但触摸板224识别由用户的手作出的接触印痕的多种特征。在这种情况下,考虑到印痕的尺寸和近似度,在左区域242识别的多个接触印痕被触摸板224解释为无意的。因此,对左区域242上的动作不予理睬。替换地,所有左区域242可以未激活,或者输入被忽略或滤除。但是,触摸板224右区域246的单个接触印痕被认为是有效的触摸板动作,并以适当的触摸板命令(例如,拖拉、点击)作出响应。在一个实施方案中,触摸板224的中央区域244也可能是激活的,并响应触摸板的感应。
在替换的实施方案中,触摸板224能够是多输入的或双手输入的。再次参考图6,触摸板224可以接受右手282手指的接触印痕,用于光标控制操作。当联系到触摸板输入设备功能性时,左手280的接触印痕也可被接受。例如,左手280的两个手指可用来控制显示屏上(例如,显示屏212)对象或数据的滚屏、扫视、旋转和缩放。
图4-6示出触摸板224分成三个独立感应区。然而,可以意识到在触摸板224上可分成任何数量的感应区,而不一定是与图示的大小成比例。例如,传感器240可以将一个手指每次的伸展和缩回探测为单个手指在触摸板224和键盘222之间来回移动,在两个地方都是活动的,而没有移动整个手。也可以认识到,触摸板224能在若干部分中被激活/停用。通过忽视任何被确定为与无意接触而不是有意的界面动作有关的具体输入,也可以每次一个输入(即接触印痕)地被激活/停用。也就是,如果触摸板224忽视某个特定的输入,即使下个输入可能不被忽视,那么触摸板224也是“停用”的。
图7-9更详细地示出了一个实施方案中用户手指在键盘222的键上的感应。在图7的侧视图中,左手280图示为相对于打开状态的便携式计算机200(即显示部件210相对于基座部件220旋转打开)处于打字状态。手掌281放在触摸板224上,手指283伸展在传感器240和键盘222上方。如上所述,由于触摸板224的额外宽或伸长的尺寸,用于手掌281的手掌放置部分包括触摸板224。图8示出了图7中沿线A-A穿过基座部件220、传感器240和左手280的横截面图。在一个实施方案中,传感器240包括第一成像传感器275和第二成像传感器276。成像传感器可以是“仰”视(虚线标记的)并“看到”A-A方向的横截面图的红外线(IR)传感器。第一和第二成像传感器275、276检查从传感器240的大致线向上延伸的空间平面区域。例如,左手280的手指283中断由第一传感器275检查的平面区域。手指283的感应与触摸板224上(例如,图4中示出的左区域242上)手掌281的接触印痕有关,因此,整个左区域242不会为任何类型的触摸板操作而激活或者手掌281做出的特定接触印痕将被拒绝,以允许手掌281放置在触摸板224上。由于第二传感器276沿其平面区域部分没有探测到任何中断,所以触摸板224与第二传感器276相关联的部分对触摸板命令或操作(例如中间区域244和右区域246)作出响应。
图9示出用于传感器240的传感机制的替换实施方案。多个光发射器探测器对(例如,对277、278)设在沿传感器带的区域,探测用户的手有没有在感应面(即从传感器240的所有线向上扩展的空间中的平面区域)中。发射探测器对产生的结果与以上参考图8所描述的IR传感器(例如,第一和第二传感器275、276)产生的结果相同。左手280的手指283中断由靠近传感器240一侧的发射探测器对277、278检查的平面区域。手指283的感应与触摸板224上(例如,图4中示出的左区域242)手掌281的接触印痕有关,因此,整个左区域242不会被任何类型的触摸板操作激活或者手掌281的特定接触印痕会被拒绝,以允许手掌281放置在触摸板224上。发射探测器对277、278沿靠近手指283另一端的平面区域没有探测到任何中断。因此,触摸板224与未探测到的传感器区域相关联的部分对触摸板命令或操作(例如中间区域244和右区域246)作出响应。
第一传感器275和第二传感器276的红外线传感器以及光发射器探测器对277、278只是用来探测手的位置的多种可能的感应机制中的两种。在替换实施方案中,传感器240可以是电容传感器或可见光/阴影传感器。如图所示,可以意识到并不是必须要有加大或宽触摸板与传感器一起使用来探测手的位置。在此描述的IR传感器和光发射探测传感器可能与任何尺寸的触摸板(例如,与中央区域244具有可比尺寸的触摸板)有关联。
再次参照图3,在基座部件220的内部可能有所有基本的公知电子电路,用于便携式计算机200的操作,例如中央处理单元(CPU)、存储器、硬盘驱动、软盘驱动、闪存驱动、输入/输出电路和电源。在现有技术中,便携式计算机这样的电子电路是公知的;例如,便携式计算机是加利福尼亚州Cupertino的Apple Computer公司的Macintosh PowerBook。
键盘222和触摸板224几乎占据了基座部件220的整个上表面232。在一个实施方案中,显示部件210具有与基座部件220的宽度217和长度219基本相同的宽度211和长度213,以便当显示部件210被闭合到基座部件220上方时,两部件的边缘相互齐平。在一个具体的实施方案中,便携式计算机200具有12英寸(大约305毫米(mm),从显示屏的一个角到相对角的对角距离)大小的显示屏。显示部件宽度211和基座部件宽度217大约为277mm,显示部件长度213和基座部件的长度219大约为219mm。键盘222基本上沿着基座部件220的宽度居中,宽227约为274mm,长228约为108mm。
在一个实施方案中,键盘222可以是标准尺寸键盘(即,键盘布局与传统台式计算机键盘的尺寸相同),具有传统的“QWERTY”布局,也包括大的、加长的空格键位于键盘的最下面一行。使用的键盘的类型(例如“QWERTY”键盘)并不是本发明的关键。
触摸板224具有加长的宽度,基本上与键盘222的宽度相同。触摸板的宽度还与基座部件220的宽度基本相同。例如,某些实施方案中的触摸板的宽度大约是基座部件宽度的70-80%。一般地说,在其他实施方案中,触摸板的宽度可以是基座部件宽度的大约50%-95%。手掌放置区的基本部分(例如,大于50%,典型地,大于60%)还可包括一个或多个触摸板。触摸板的宽度223沿着键盘222的宽度227延伸,以在打字时提供手掌放置区。在一个实施方案中,触摸板224的宽度223约为274mm,长度225约为45mm。当触摸板224作为相连的触摸板示出时,在替换实施方案中,一些分隔开的触摸板可设在左、右或中央手掌放置区,这些分隔开的触摸板占据手掌放置区的基本部分(例如,约60%-70%)。
在替换实施方案中,便携式计算机200具有大小为17英寸(大约432mm,从显示屏的一个角到对角的对角距离)的显示屏。显示部件宽度211和基座部件宽度217约为392mm,显示部件长度213和基座部件长度219大约259mm。键盘222可以是标准尺寸键盘,基本上沿基座部件220的宽度居中。键盘222有约为274mm的宽度227和约为108mm的长度228。设在17英寸显示屏的基座部件220上的触摸板224具有伸长的宽度,与键盘222的宽度基本相同或超过键盘222的宽度。17英寸显示屏的基座部件的宽度大于12英寸显示屏的基座部件。尽管,由于显示屏的两个尺寸,键盘222的尺寸基本上是不同的,基座部件还是需要为17英寸的显示屏提供更大的表面区域。因此,对于17英寸显示屏的基座部件,触摸板224形成的手掌放置区更大。在一个实施方案中,触摸板224的宽度223在约274mm到约330mm之间,长度225在约45mm到约55mm之间。
键盘222的尺寸尤其是触摸板的尺寸只是实例,应该注意的是,例如,依据显示屏212和基座部件上可利用的表面区域的尺寸,可以使用更大的布局尺寸。在一个实施方案中,触摸板224的宽度223可以在约100mm到约400mm之间,长度225在约45mm到约200mm之间。
图10示出了支持宽触摸板和/或手传感器的便携式计算机系统300(例如,对于便携式计算机200)的一个实施方案的逻辑图。注意,图10中示出多种计算机系统的组件,这并不意味着代表组件互连的任何特定结构或方式,像这样的细节与本发明并无密切关系。在一个实施方案中,所述组件的相应硬件组件可被设在所示的母板301上。图10的计算机系统例如可以是Apple Macintosh便携式计算机。
便携式计算机系统300包括主逻辑板或母板301,其具有至少一个中央处理单元(CPU)或处理器302,一个或多个易失存储器单元304,如随机存储器(RAM)和只读存储器(ROM),耦接到母板301,还有图像处理器308。多个处理器302是系统300的一部分(例如,双处理器系统,或双核处理器系统)。处理器302例如可以是Motorola公司或IBM公司的G4或G5微处理器,被耦接到缓存306。
存储器控制器303考虑到用CPU 302作为存储单元304和图像处理器308的接口。图像处理器308也耦接到显示设备(例如,显示屏212),其可以是高分辨率设备。存储器控制器303也定义了在CPU 302、存储单元304和图像处理器308之间总线305上流动的数据的速率。总线305也称为前端总线(FSB)、处理器总线、存储器总线或系统总线。输入/输出(I/O)控制器320管理其他耦接到母板301的组件的接口,例如存储设备324(非易失存储器)和本地I/O322。I/O类型的设备包括鼠标、调制解调器、网络接口、打印机、扫描仪、视频摄像机和本领域中所公知的其他设备。
一个实施方案中,考虑到传感器240识别用户手的位置,在软件中,接受或拒绝触摸板224上的接触印痕,至少部分被具体化。即,通过响应处理器例如微处理器,执行包含在存储器如存储器304(可包括ROM、RAM、缓存或远程存储设备)中的指令序列,该技术在计算机系统或其他数据处理系统中实现。在多种实施方案中,硬布线电路与软件指令结合使用来实现本发明。因此,技术并不限制于硬布线电路和软件的任何特定结合或数据处理系统执行的指令的任何特定资源。另外,贯穿整个说明书,多种功能和操作被描述为由软件代码所执行或所引起而简化说明。然而,本领域技术人员认识到这样表述的意思是,功能是由处理器例如CPU 302执行代码产生的。
机器可读介质能用来存储软件和数据,当数据处理系统执行时,能引起系统执行本发明的不同方法。这可执行的软件和数据存储在不同地方,包括如图7中所示的存储器304、缓存306或存储设备324。这个软件和/或数据的部分可存储在这些存储设备的任何一个中。因此,机器可读介质包括以机器(例如,计算机、网络设备、个人数字管理、生产工具、具有一组一个或多个处理器的任何设备,等等)可访问的方式提供信息的任何机制。例如,机器可读介质包括可记录/不可记录介质(例如,只读存储器(ROM);随机访问存储器(RAM);磁盘存储介质;光存储介质;闪存设备等),还有电、光、声或其他形式的传播信号(例如,载波、红外线信号、数字信号等)等。
在本发明的至少一个实施方案中,传感器被设在便携式计算机的基座部件上来探测手的位置。如果手的位置是从触摸板的接触印痕伸展到键盘,那么特定的接触印痕被计算机系统识别为无意的或意外的接触,因此不作为触摸板命令记录。图11示出在触摸板上拒绝或接受接触印痕操作的一个实施方案的流程图,该接触印痕与手的位置相关联。该操作对每个在触摸板上探测到的接触印痕都执行。在一个实施方案中,电容触摸板(例如,触摸板224)设在基座部件(例如,220)的上表面(例如,表面232),感应触摸板上的接触印痕。触摸板感应到的任何接触经过后处理程序算法,这是为了适当地解释该接触。在一个实施方案中,后处理程序在此定义为将触摸板传感器传来的信息转换为便携式计算机(例如,处理器302)可解释的格式的软件或固件。后处理程序把触摸板输出作为输入,其可包括对触摸板做出的任何类型的物理接触。接着,后处理程序使用“后处理程序算法”来分析每组输入(位置、宽度、接触次数、存在接触和手的位置),以便确定接触印痕是否应该接受或拒绝。
当便携式计算机处于电源“开”的状态中,操作400的开始点402处,显示屏可视(例如,显示图象或数据),多种输入设备(例如,键盘222、传感器240和触摸板224)处于激活和应答状态中。当接触印痕在触摸板上被感应到,确定接触印痕的位置、轨迹和尺寸,方框404。轨迹涉及接触印痕的路径(例如,在拖拉操作中,手指在触摸板上的移动)。接触印痕可能是,例如,在打字(例如,图7的手掌281)或点击(例如,图5的右手282)时手的手掌区域。接着,使用设在便携式计算机的基座部件上的传感器(例如,传感器240)得到手的位置,方框406。在一个实施方案中,传感器可包括沿传感器带设在键盘和触摸板之间的一个或多个IR传感器(例如,传感器275、276)。在替换实施方案中,传感器可以是沿传感器带设在键盘和触摸板之间的光发射器探测器对(例如,对277、278)。
一旦手的位置被确定,使用接触印痕的测量值,接触印痕的位置、轨迹、尺寸,还有传感器探测到的手的位置,估计有意接触的概率,方框408。如上讨论,触摸板可能分成多个感应区域,例如,左传感器区域242、中央传感器区域244和右传感器区域246,或者有分隔开的触摸板,每个区域有一块,这些区域被非触摸板的小区域分隔开。例如,手掌281放置在左传感器区域242形成的接触印痕的尺寸相比点击或拖拉光标操作时移动手指(例如,图5中示出的右手282手指在右传感器区域246上方)形成的接触印痕大。在一个实施方案中,具有相对小的尺寸和沿触摸板表面一定距离的轨迹的接触印痕,结合传感器的无探测,将以有意接触的高概率开始估计。这可能对应于例如点击或拖拉光标操作。相反,大尺寸的接触印痕、无轨迹或最小轨迹,结合传感器的探测,将以有意接触非常低的概率开始估计。这可能与手掌放置在触摸板表面相符。
对估计的概率重复计算,为接触印痕建立精确或严格的接受/拒绝标准,方框410,接触印痕也在一段时间内重复测量,方框412。这些计算被重复进行来向系统提供最新的抽样数据。在一个具体实施方案中,测量在约120Hz到约3Hz的范围内重复。最后,接触印痕基于从测量的接触印痕/传感器计算建立的标准被接受或拒绝,方框414。一旦接受/拒绝的决定做出,操作就结束了,方框416。
参考图4-5的场景进一步描述接受/拒绝操作400。图4示出了传统打字状态,双手的手掌放置在触摸板224上,手指伸展在键盘222上。左传感器区域242和右传感器区域246上的接触印痕被拒绝。手掌做出的相对大尺寸的接触印痕,与手的位置的探测有关,将解释为无意或意外的接触。在这种状态下,触摸板224只用作手掌放置功能。图5示出了双模式状态,其中左手280处于打字位置,右手282处于触摸板位置。因为传感器240探测到左手280的位置,所以左手280(例如,手掌)的接触印痕被拒绝。因此,与左手280位置和接触印痕相关的整个左传感器区域242,或者左手280在左传感器区域242上的特定接触印痕不为触摸板命令激活。右手282手指的接触印痕将作为有意接触而接受。传感器将不探测与右传感器区域246相关联的任何手的存在。如上所述,操作400执行的计算包括测量右手282接触印痕的尺寸和轨迹。也与左手280的接触印痕进行比较来建立接受/拒绝的标准。
图12示出可设在便携式计算机上的手探测传感器的替换实施方案。便携式计算机500图示为打开位置,显示部件510参考基座部件520旋转打开。基座部件520包括设在键盘522以下的宽触摸板524。成像传感器545设在框架显示屏512的框514上。成像传感器545探测基座部件520的包括键盘222和触摸板524的区域。当激活时,成像传感器545探测特定的手的位置以及如上所述(例如,操作400)的建立接受/拒绝标准。在替换的实施方案中,当不作为成像传感器操作时,成像传感器545也可提供视频会议的功能。
在前述的说明中,本发明已参照具体的示例性实施方案进行描述。但是,显然可以对其做出多种修改和改变而不背离本发明更宽的精神和范围,如所附权利要求所述。因此,说明书和附图被认为是说明性的,而非限制性的含义。
