    • A rotatable wheel for an input device which interfaces with a computer. The input device includes both a permanent magnet and an electromagnet. A rotor of material which will magnetically interact with the permanent magnet and electromagnet is coupled to the rotatable wheel. The permanent magnet and electromagnet can be used to control a ratchet force applied to the rotatable wheel. In an alternate embodiment, a rotatable wheel with a flywheel is engaged with a roller. A ratchet wheel can be intermittently engaged with the flywheel to provide a ratchet force. By disengaging the ratchet wheel, the flywheel can be allowed to spin, providing momentum to allow for easier scrolling in certain conditions, such as for scrolling through a long document.
    • 用于与计算机接口的输入装置的可旋转轮。 输入装置包括永磁体和电磁体。 将与永磁体和电磁体磁性相互作用的材料的转子耦合到可旋转的轮。 永久磁铁和电磁铁可用于控制施加到可旋转轮的棘轮力。 在替代实施例中,具有飞轮的可旋转轮与辊接合。 棘轮可以间歇地与飞轮接合以提供棘轮力。 通过松开棘轮,可以允许飞轮旋转,提供动量以允许在某些条件下更容易地滚动,例如滚动通过长文档。
