    • A capacitive pointing device includes a capacitive sensor unit, a switch unit, and an operating unit. The capacitive sensor unit has a receiving space receiving the switch unit, and a plurality of capacitive sensors disposed around the receiving space. The operating unit is spaced apart from the capacitive sensors, and is configured to result in a capacitance effect with the capacitive sensors. The operating unit is movable toward the capacitive sensor unit to trigger the switch unit, and is movable horizontally relative to the capacitive sensors. Capacitance variation between the operating unit and each of the capacitive sensors is used for determining a moving direction and an amount of movement of the operating unit.
    • 电容性指示装置包括电容式传感器单元,开关单元和操作单元。 电容式传感器单元具有接收开关单元的接收空间和设置在接收空间周围的多个电容式传感器。 操作单元与电容传感器间隔开,并且被配置成导致电容传感器的电容效应。 操作单元可朝向电容式传感器单元移动以触发开关单元,并且可相对于电容式传感器水平移动。 操作单元和每个电容式传感器之间的电容变化用于确定操作单元的移动方向和移动量。
