    • According to one aspect of the invention, a movable cursor control device is provided for controlling a cursor on a display screen of a digital processing system. One exemplary cursor control device comprises a housing, an electromagnetic emitting device coupled to the housing, and an electromagnetic detector coupled to the housing. The electromagnetic detector detects reflections of signals emitted from the electromagnetic emitting device and determines when the housing has been lifted from a surface. In another aspect of the invention, an exemplary method is provided for controlling a cursor on a display screen of a digital processing system. The exemplary method includes holding the cursor relative to an object on the display screen using a cursor control device activated by a user, detecting that the user no longer activates the cursor control device, and detecting that the user has lifted the cursor control device from a surface when the cursor control device is no longer activated by the user. Further, the method allows for continuing to hold the cursor relative to the object after detecting that the user no longer activates the cursor control device.
    • 根据本发明的一个方面,提供一种用于控制数字处理系统的显示屏上的光标的可移动光标控制装置。 一个示例性光标控制装置包括壳体,耦合到壳体的电磁发射装置和耦合到壳体的电磁检测器。 电磁检测器检测从电磁发射装置发射的信号的反射,并确定壳体何时已经从表面升起。 在本发明的另一方面,提供了一种用于控制数字处理系统的显示屏幕上的光标的示例性方法。 示例性方法包括使用由用户激活的光标控制装置来相对于显示屏上的对象来保持光标,检测到用户不再激活光标控制装置,并且检测到用户已经将光标控制装置从 光标控制装置不再被用户激活时的表面。 此外,该方法允许在检测到用户不再激活光标控制装置之后,相对于对象继续保持光标。
