Method and device for recognizing a dual point user input on a touch based user input device
摘要：
A dual point user input is recognized on a touch based user input device that is only capable of outputting a single input position signal by forming or detecting a first position signal, preferably storing the position signal, forming or detecting a subsequent second position signal and determining if the second position has its source in a simultaneous dual point user input.
摘要（中）：

在基于触摸的用户输入设备上识别双点用户输入，其仅能够通过形成或检测优选地存储位置信号的第一位置信号来输出单个输入位置信号，形成或检测随后的第二位置信号并确定 如果第二个位置具有同时双点用户输入的源。
