    • The computer pointing input device allows a user to determine the position of a cursor on a computer display. The position of the input device in relation to the display controls the position of the cursor, so that when a user points directly at the display, the cursor appears at the intersection of the display and the line of sight from of the input device. When the device is moved, the cursor appears to move on the display in exact relation to the input device. In addition, a cursor command unit allows the user to virtually operate the input device wherein changes in the position of the device allow the user to spatially invoke mouse functions. The computer pointing input device is designed to operate with a computer having a processor through a computer communication device.
    • 计算机指向输入装置允许用户确定光标在计算机显示器上的位置。 输入设备相对于显示器的位置控制光标的位置,使得当用户直接指向显示器时,光标出现在来自输入设备的显示器和视线的交点处。 当设备移动时,光标似乎在与输入设备完全相关的显示屏上移动。 此外,光标命令单元允许用户虚拟地操作输入设备,其中设备位置的改变允许用户在空间上调用鼠标功能。 计算机指向输入设备被设计成通过计算机通信设备与具有处理器的计算机一起操作。
