    • A method and apparatus are provided for reliably detecting a touch operation in a touch sensitive control surface, despite the influence of light or the existence of an obstruction. In the touch tracer, LEDs and phototransistors for detecting a touch position on the input pad are arranged to form parallel optical axes in the vertical direction and the horizontal direction. The optical axes of the LEDs and the phototransistors are alternately arranged in opposite directions to the adjacent optical axis. Moreover, the front surface of the phototransistor is closed except for an aperture that forms an optical axis only between opposing LEDs. The apertures are divided in half into top and bottom portions by a light-shielding film. Because of the light-shielding film, the phototransistor does not receive any light interference from the adjacent LED or incidental sunlight.
    • 提供了一种用于可靠地检测触敏控制表面中的触摸操作的方法和装置,尽管受到光的影响或阻塞的存在。 在触摸示踪器中,用于检测输入焊盘上的触摸位置的LED和光电晶体管被布置成在垂直方向和水平方向上形成平行的光轴。 LED和光电晶体管的光轴交替地布置成与相邻光轴相反的方向。 此外,除了仅在相对的LED之间形成光轴的孔之外,光电晶体管的前表面是封闭的。 通过遮光膜将孔分成一半分成顶部和底部。 由于光屏蔽膜,光电晶体管不会受到相邻LED或偶发阳光的任何光干扰。

    • A display device is disposed in a car and a display screen is switched based upon coordinate data showing the touched position which is output from a touch tracer which is disposed where it can be accessed by a driver, and “on” data that shows that the touch tracer has been press-operated. The display device displays small button display portions to select a next display operation which is to be displayed on the map screen. The button display portions which are shown on the map screen in an input state of the coordinate data from the touch tracer are displayed in an expanded state. By so doing, the driver can easily confirm the display content of the button display portions so that it is possible to improve the operability of the touch tracer for the selection of the button display portions.
    • 显示装置设置在轿厢中,并且基于表示从设置在驾驶员可以访问的触摸跟踪器输出的触摸位置的坐标数据来切换显示屏,并且显示“开”数据 触摸示踪剂已被压制操作。 显示装置显示小按钮显示部分,以选择要在地图画面上显示的下一个显示操作。 在来自触摸跟踪器的坐标数据的输入状态下在地图画面上示出的按钮显示部分以展开状态显示。 通过这样做,驾驶员可以容易地确认按钮显示部分的显示内容,使得可以提高用于选择按钮显示部分的触摸跟踪器的可操作性。
