Abstract:
An input device includes an input device chassis. At least one tactile feedback module is coupled to the input device chassis. The tactile feedback module includes a first electromagnet and a second electromagnet located in a spaced apart relationship from the first electromagnet. A mass includes a pair of opposing ends and is located between the first electromagnet and the second electromagnet. A permanent magnet is located on each of the opposing ends of the mass. The mass is operable to move along an axis between the first electromagnet and the second electromagnet and may be moved to produce a variety of forces on the input device in order to provide tactile feedback.
