    • PROBLEM TO BE SOLVED: To provide one-dimensional signals suitable for scrolling or other user interface functions in response to two-dimensional inputs produced by a touchpad or other input devices.SOLUTION: A current chirality (102) of a two-dimensional input is determined to have a first direction if the two-dimensional input shows a clockwise trajectory mainly, and is determined to have a second direction if the two-dimensional input shows a counterclockwise trajectory mainly. One-dimensional variables (104) are stored using a magnitude being a function of a distance reflected by the two-dimensional input and a sign based on the current chirality. Next, a one-dimensional input to a computer system may be properly extracted from the stored one-dimensional variables. The method explained in this text is formal, and therefore, one pointing device can be used for both two-dimensional inputs and one-dimensional inputs.
    • 要解决的问题:响应于由触摸板或其他输入设备产生的二维输入,提供适合于滚动或其他用户界面功能的一维信号。 解决方案:如果二维输入主要显示顺时针轨迹,则二维输入的当前手性(102)被确定为具有第一方向,并且如果二维输入则确定为具有第二方向 主要显示逆时针轨迹。 使用由二维输入反映的距离的量值和基于当前手性的符号来存储一维变量(104)。 接下来,可以从存储的一维变量中适当地提取对计算机系统的一维输入。 本文中解释的方法是正式的,因此,一个指向装置可以用于二维输入和一维输入。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide methods, systems and devices for detecting a position-based attribute of a finger, stylus or other object with a touchpad or other sensor having a touch-sensitive region that includes a plurality of electrodes.SOLUTION: Modulation signals for one or more electrodes are produced as a function of any number of distinct digital codes. The modulation signals are applied to associated at least one of the plurality of electrodes to obtain a resultant signal that is electrically affected by the position of the object. The resultant signal is demodulated using the plurality of distinct digital codes in order to discriminate electrical effects produced by the object. The position-based attribute of the object is then determined with respect to the plurality of electrodes from the electrical effects.
    • 要解决的问题:提供用于通过触摸板或具有包括多个电极的触敏区域的其他传感器检测手指,触笔或其他物体的基于位置的属性的方法,系统和装置。解决方案:调制信号 作为任何数量的不同数字码的函数产生一个或多个电极。 调制信号被施加到相关联的多个电极中的至少一个电极,以获得由物体的位置电气影响的结果信号。 使用多个不同的数字码解调所得到的信号,以便区分由对象产生的电效应。 然后,根据电效应,相对于多个电极确定对象的基于位置的属性。
