Abstract
在根据本公开的方面的示例实施方式中,一种方法可以包括:确定计算设备的键盘何时在计算设备的显示器表面上,以及在做出确定时,使用显示器表面的被键盘覆盖的一部分来为键盘提供可配置的背光。
Description
背景技术
移动计算的出现和普及使得便携式计算设备由于它们的紧凑设计和轻重量而成为当今市场中的主要产品。平板电脑是广泛使用的便携式计算设备的示例。平板电脑通常在设备的显示器表面上采用触摸屏,该触摸屏可用于观看和输入。这些设备的用户可以借助于手指或手写笔手势与触摸屏交互。作为示例,可以在触摸屏表面上图示用于录入字符的屏幕上键盘。
附图说明
图1图示根据示例的计算设备,该计算设备包括触摸屏显示器表面和能与计算设备一起使用的物理键盘;
图2A至图2C提供根据示例的计算设备的触摸屏显示器表面可以如何用于为键盘提供背光的图示;以及
图3是根据本公开的示例的流程图。
具体实施方式
随着诸如平板电脑之类的便携式计算设备的计算能力不断增加,用户可能希望扩展这些设备的使用,例如,仅在这些设备的显示器表面上采用触摸屏用以观看和输入。作为示例,可以使用各种***设备来扩展便携式计算设备的使用。这种***设备的示例包括但不限于键盘。关于键盘,可存在用户可能希望借助于外部物理键盘输入字符的情况,特别是当创建内容或长时间段打字时(例如创建文档、电子表格或幻灯片)。
本文所公开的示例提供了计算设备(诸如平板电脑或具有双屏幕显示器的笔记本设备)的显示器表面在***设备用于操作计算设备时,点亮该***设备(例如键盘)的能力。由显示器表面给出的点亮可以在***设备使用时为该***设备提供背光,这在当***设备在黑暗的周围状况中使用时或者当***设备由在其使用时必须定期查看***设备的用户(例如看着键盘打字的打字员)使用时,可能特别有用。通过依靠由显示器表面提供的点亮为***设备提供背光,不需要在***设备中内建背光,这节省了成本并且保持了***设备的低复杂性。另外,***设备的厚度也可以保持较低,这可能是用户期望的。此外,计算设备的显示器表面可用的所有颜色可用于提供可配置的背光,如将进一步描述的。
参考附图,图1图示根据示例的计算设备100,计算设备100包括触摸屏显示器表面102和物理键盘104,当键盘104在触摸屏显示器表面102上时,物理键盘104能与计算设备100一起使用。如将进一步描述的,由显示器表面102提供的点亮可用于在键盘104被使用时为键盘104提供可配置的背光。计算设备100的示例包括但不限于平板电脑或具有双屏幕显示器的笔记本设备。作为示例,具有双屏幕显示器的笔记本设备可以参考可旋转地彼此连接的两个显示构件,显示构件中的一个还用作基底构件。根据示例,用作基底构件的显示构件可以指代触摸屏显示器表面102。
计算设备100描绘了处理器106和存储器设备108,并且作为执行其操作的计算设备100的示例,存储器设备108可以包括由处理器106可执行的指令110-114。因此,存储器设备108可以被称为当由处理器106执行时实现计算设备100的部件的存储程序指令。作为示例,存储在存储器设备108中的可执行程序指令包括:确定键盘104的放置的指令(110)、使用显示器表面102来提供背光的指令(112)以及控制点亮的指令(114)。
确定键盘104的放置的指令(110)表示一程序指令,该程序指令当由处理器106执行时,使计算设备100确定键盘104何时在触摸屏显示器表面102上。键盘104在触摸屏显示器表面102上的放置的检测可以变化。作为示例,霍尔效应传感器可以用于检测键盘104在触摸屏显示器表面102上的放置。例如,霍尔效应传感器可以布置在计算设备100内(例如,在触摸屏显示器表面102下方),并且检测当布置在键盘104内的磁性构件放置在霍尔效应传感器附近时生成的磁场。当由霍尔效应传感器检测到的磁场达到或超过阈值时,计算设备100可以确定键盘104被布置或放置在触摸屏显示器表面102上。作为示例,一旦由霍尔效应传感器检测到的磁场降到阈值以下,计算设备100就可以确定键盘104已经从触摸屏显示器表面102移除。
使用显示器表面102来提供背光的指令(112)表示一程序指令,该程序指令当由处理器106执行时,使计算设备100在做出键盘104已经被放置在触摸屏显示器表面102上的确定时,使用触摸屏显示器表面102的被键盘104覆盖的一部分来为键盘104提供可配置的背光。作为示例,可以基于用户偏好或环境配置背光。如上面所提及的,由计算设备100的触摸屏显示器表面102可用的所有颜色可用于提供例如由用户可配置的背光。关于环境,除了其他示例,基于计算设备100所处的周围状况或位置的光亮或者当前在计算设备100上运行的应用,不同的点亮颜色和不同的亮度级别可以用于为键盘104的各个部分提供背光。
作为使用触摸屏显示器表面102来为键盘104提供背光的示例,计算设备100可以点亮显示器表面102的被键盘104覆盖的像素的子集,以及关掉显示器表面102的被键盘104覆盖的其他像素。例如,用户可能更喜欢使键盘104的键而不是键盘104的围绕键的框架从背后照亮,或者反之亦然。基于用户偏好,可以点亮显示器表面102的被键盘104覆盖的适当像素(例如键),同时可以关掉显示器表面102的被键盘104覆盖的其他像素(例如键盘104的围绕键的框架)。
根据示例,为了促进电池节省,触摸屏显示器表面102可以是有机发光二极管(OLED)显示器。结果,当触摸屏显示器表面102的被键盘覆盖的某些像素不需要从背后照亮时,OLED技术提供了独立关掉像素以产生黑色的能力,从而在过程中节省能量。类似地,当每个像素提供其自己的点亮时,仅打开提供背光所需的那些像素。作为示例,当触摸屏显示器表面102上的其中提供背光的区域基于使用而改变时,最初关掉的像素可以被点亮来为键盘提供可配置的背光。
作为示例,除了使用触摸屏显示器表面102来为键盘104提供背光之外,如果确定键盘104的键是透明的,则计算设备100还可以从显示器表面102的被键盘104覆盖的部分为键盘104的每个键图示字符。结果,当用户在特定键上按压时,触摸屏显示器表面102可以检测到该键按压并且处理用户录入的输入。关于可配置性,可以图示多个键盘字符布局、语言、符号和颜色,所有这些都具有相同或不同的亮度级别。作为示例,当在GPS应用中录入地址时,只有可能的数字或字母在用户键入时被点亮,因为GPS应用可以知道接下来将键入哪些数字和/或字母。
控制点亮的指令(114)表示一程序指令,该程序指令当由处理器106执行时,使计算设备100控制触摸屏显示器表面102的未被键盘104覆盖的另一部分的点亮。作为利用如上所述的OLED技术的示例,可以关闭表示显示器表面102的未被键盘104覆盖的该另一部分的像素,以便促进功率节省。这对于具有双屏幕显示器的笔记本设备可能特别有用,其中用作基底构件的显示构件具有布置在基底构件上的键盘104,而另一显示构件用于观看目的。然而,除了关闭显示器表面102的未被键盘104覆盖的部分,例如,在放置键盘104之前,显示器表面102上最初图示的内容可以被重新缩放到显示器表面的未被键盘104覆盖的部分,这在显示器表面102是计算设备100(例如平板电脑)的唯一可视屏幕时特别有用。
存储器设备108通常表示能够存储可由处理器106执行的指令的任何数量的存储器部件。在不包含瞬态信号而是由被配置为存储相关指令的至少一个存储器部件构成的意义上,存储器设备108是非瞬态的。结果,存储器设备108可以是非瞬态计算机可读存储介质。存储器设备108可以在单个设备中实现或者跨设备分布。同样地,处理器106表示能够执行由存储器设备108存储的指令的任何数量的处理器。处理器106可以集成在单个设备中或跨设备分布。进一步,存储器设备108可以完全或部分地与处理器106集成在相同的设备中,或者它可以是独立的但可访问该设备和处理器106。
在一个示例中,程序指令110-114可以是在安装时可由处理器106执行以实现计算设备100的部件的安装包的一部分。在这种情况下,存储器设备108可以是诸如CD、DVD或闪存驱动器的便携式介质,或者是可以由安装包可以从其下载和安装的服务器维护的存储器。在另一示例中,程序指令可以是已经安装的应用的一部分。这里,存储器设备108可以包括诸如硬盘驱动器、固态驱动器等的集成存储器。
图2A至图2C提供根据示例的计算设备100的触摸屏显示器表面102可以如何用于为键盘104提供背光的图示。参考图2A,在放置键盘104之前,触摸屏显示器表面102的整个屏幕可以用于提供内容,如202所图示。然而,如图2B中所图示,一旦键盘104布置在触摸屏显示器表面102上,在放置键盘104之前显示器表面102上最初图示的内容(例如图2A中的202)就可以被重新缩放到显示器表面102的未被键盘104覆盖的部分,如204所图示。然而,为了促进功率节省,作为利用上述OLED技术的示例,可以关闭表示显示器表面102的未被键盘104覆盖的部分的像素,如图2C中所图示。这对于具有双屏幕显示器的笔记本设备可能特别有用,其中用作基底构件的显示构件具有布置在基底构件上的键盘104,而另一显示构件用于观看目的。
作为示例,如上文所述,键盘104在触摸屏显示器表面102上的放置的检测可以使用霍尔效应传感器。例如,霍尔效应传感器可以布置在计算设备100内(例如,在触摸屏显示器表面102下方),并且检测当布置在键盘104内的磁性构件放置在霍尔效应传感器附近时生成的磁场。当由霍尔效应传感器检测到的磁场达到或超过阈值时,计算设备100可以确定键盘104被布置或放置在触摸屏显示器表面102上。一旦做出该确定,就可以重新缩放触摸屏显示器表面102上最初图示的内容,如图2B中所图示,或者可以关闭表示显示器表面102的未被键盘104覆盖的部分的像素,如图2C中所图示。作为示例,一旦由霍尔效应传感器检测到的磁场降到阈值以下,计算设备100就可以确定键盘104已经从触摸屏显示器表面102移除。作为示例,然后触摸屏显示器表面102上图示的任何内容可以重新缩放以占据整个屏幕,如图2A中所图示。
如上文所述,作为示例,基于用户偏好或环境,背光可以是可配置的。此外,由触摸屏显示器表面102可用的所有颜色可用于提供背光。作为用户偏好的示例,如果用户更喜欢使键盘104的键206而不是键盘104的围绕键206的框架从背后照亮,则可以点亮显示器表面102的被键206覆盖的像素的子集,同时可以关闭显示器表面102的被框架覆盖的其他像素。类似地,如果用户喜欢使框架而不是键206从背后照亮,则可以点亮显示器表面102的被框架覆盖的像素的子集,同时可以关闭显示器表面102的被键206覆盖的其他像素。除了其他示例,作为基于环境(计算设备100所处的周围状况或位置的光亮或者当前在计算设备100上运行的应用)配置背光的示例,不同的点亮颜色和不同的亮度级别可以用于为键盘104的各个部分提供背光。例如,当在GPS应用中录入地址时,只有可能的数字或字母在用户键入时被点亮,因为GPS应用可以知道接下来将键入哪些数字和/或字母。
图3是根据示例的由计算设备采取的用于实现计算设备的显示器表面为能与计算设备一起使用的键盘提供背光的方法的步骤的流程图300。在讨论图3时,可以参考图1至图2中所图示的示例计算设备100。这样的参考是为了提供上下文示例而不是限制可以实现由图3所描绘的方法的方式。
在310处,计算设备确定键盘何时在计算设备的显示器表面上。键盘在显示器表面上的放置的检测可以变化。作为示例,霍尔效应传感器可以用于检测键盘在显示器表面上的放置。例如,霍尔效应传感器可以布置在计算设备内(例如,在显示器表面下方),并且检测当布置在键盘内的磁性构件放置在霍尔效应传感器附近时生成的磁场。当由霍尔效应传感器检测到的磁场达到或超过阈值时,计算设备可以确定键盘被布置或放置在显示器表面上。
在320处,在做出键盘在计算设备的显示器表面上的确定时,计算设备使用显示器表面的被键盘覆盖的一部分来为键盘提供可配置的背光。作为示例,基于用户偏好或环境,背光可以是可配置的。此外,由计算设备的显示器表面可用的所有颜色可用于提供例如由用户可配置的背光。关于环境,除了其他示例,基于计算设备所处的周围状况或位置的光亮或者当前在计算设备上运行的应用,不同的点亮颜色和不同的亮度级别可以用于为键盘104的各个部分提供背光。
除了为键盘提供背光之外,计算设备还可以控制显示器表面的未被键盘覆盖的部分的点亮。例如,在确定键盘何时在显示器表面上时,计算设备可以将显示器表面上最初图示的内容重新缩放到显示器表面的未被键盘覆盖的部分(例如参见图2B)。此外,计算设备更可以关闭显示器表面的未被键盘覆盖的其他部分(例如,参见图2C)。
尽管图3的流程图示出了特定的执行顺序,但是执行的顺序可以与所描绘的顺序不同。例如,可以相对于所示的顺序而打乱两个或更多个框或箭头的执行顺序。另外,连续示出的两个或更多个框可以同时执行或部分同时执行。所有这些变化都在本发明的范围内。
应理解,所描述的示例可包括各种部件和特征。还应理解,阐述了许多具体细节以提供对示例的透彻理解。然而应当理解,可以在不限制这些具体细节的情况下实践这些示例。在其他情况下,可能没有详细描述公知的方法和结构,以避免不必要地模糊对示例的描述。另外,这些示例可以彼此组合使用。
说明书中对“示例”或类似语言的引用意味着结合该示例描述的特定特征、结构或特性包括在至少一个示例中,但不一定包括在其他示例中。在说明书中,在各个地方的短语“在一个示例中”或类似短语的各种示例不一定都指代相同的示例。
应理解,提供所公开的示例的先前描述是为了使所属领域的技术人员能够制作或使用本发明。对于本领域技术人员来说,对这些示例的各种修改是显而易见的,并且在不脱离本公开的精神或范围的情况下,可以将本文定义的一般原理应用于其他示例。因此,本公开不旨在限于本文所示的示例,而是符合与本文所公开的原理和新颖特征相一致的最宽范围。
