    Abstract: A method of operating a touch screen to activate one of a plurality of virtual keys is provided. A touch location is determined based on location data pertaining to touch input on the touch screen, wherein the touch input is intended to activate one of the plurality of virtual keys. Each of the plurality of virtual keys has a set of at least one key location corresponding to it. For each of the virtual keys, a parameter (such as physical distance) is determined for that virtual key that relates the touch location and the set of at least one key location corresponding to that virtual key. The determined parameters are processed to determine one of the virtual keys. For example, the determined one virtual key may be the virtual key with a key location (or more than one key location, on average) being closest to the touch location. A signal is generated indicating activation of the determined one of the virtual keys.

    Abstract translation: 提供了一种操作触摸屏以激活多个虚拟键中的一个的方法。 基于与触摸屏上的触摸输入相关的位置数据来确定触摸位置,其中触摸输入旨在激活多个虚拟键中的一个。 多个虚拟键中的每一个具有与其对应的至少一个键位置的集合。 对于每个虚拟键,确定涉及触摸位置和对应于该虚拟键的至少一个键位置的集合的该虚拟键的参数(例如物理距离)。 处理确定的参数以确定虚拟键之一。 例如,确定的一个虚拟键可以是具有最接近触摸位置的键位置(或平均多于一个键位置)的虚拟键。 产生指示所确定的虚拟键之一的激活的信号。
