摘要： General method for determining the two-dimensional location (18) of a source or sink of electric current on the surface of a resistance element (Fig. 3, 4, 9). Boundary terminations for resistance elements are described that permit location in two axes simultaneously; the same boundary terminations can be used to produce uniform two-dimensional electric fields with controllable direction. Touch panels are described that detect the presence of a user's figure (F) on such a surface, and produce output signals corresponding to the position of the finger in one or more axes. A preferred embodiment (Fig. 2) discloses a touch panel that includes a signal generator and determines the position of the user's finger from current flowing through the user' s body to ground. Another touch panel embodiment determines the position of the user's finger from currents caused by ambient electrical noise. An electronic musical instrument (Fig. 13), a transparent touch panel for use with a video display (Fig. 19), a touch-panel-controlled audio mixer (Fig. 9), and an electronic game incorporating a touch panel are also disclosed.
摘要翻译：用于确定电阻元件表面上的电流源或信宿的二维位置（18）的一般方法（图3，图4，图9）。描述了允许同时位于两个轴上的电阻元件的边界端接; 可以使用相同的边界终端来产生具有可控方向的均匀二维电场。描述了在这样的表面上检测用户身材（F）的存在的触摸面板，并产生与手指在一个或多个轴上的位置相对应的输出信号。优选实施例（图2）公开了一种触摸面板，其包括信号发生器，并且确定用户手指从流过用户身体到地面的电流的位置。另一触摸屏实施例确定用户手指从环境电噪声引起的电流的位置。电子乐器（图13），与视频显示器（图19）一起使用的透明触摸面板，触摸面板控制的音频混合器（图9）和包含触摸面板的电子游戏机也是披露。
