摘要: A method and system for entering numerical information in a manner that can be easily used by visually impaired individuals are disclosed. Using a touch screen display, for each digit of a multidigit number a first location on the screen is touched a number of times equal to the digit followed by touching a second location. Once all the digits have been entered, a third location is touched. This method allows for dividing the touch screen display into a small number of large area touch active regions, such as quadrants, thus reducing the accuracy required to enter a value since the large area quadrants are easily referenced to the screen boundaries. Further, audible cues are used to prompt the user as well as provide feedback.
摘要翻译: 公开了以视觉障碍者容易使用的方式输入数字信息的方法和系统。 使用触摸屏显示器,对于多位数字的每个数字,屏幕上的第一位置被触摸等于数字的次数,然后触摸第二位置。 一旦输入所有数字,就会触摸第三个位置。 该方法允许将触摸屏显示分成少量的大面积触摸有源区域,例如象限,从而降低输入值所需的精度,因为大面积象限容易参照屏幕边界。 此外,可听见的提示用于提示用户以及提供反馈。
