  • Patent number: 8922399
    Abstract: Illustrative embodiments of force sensitive input devices and methods are disclosed. In at least one embodiment, an input device may comprise a first input key configured to output a first analog signal as a function of force applied to the first input key, a second input key configured to output a second analog signal as a function of force applied to the second input key, a third input key configured to output a third analog signal as a function of force applied to the third input key, a fourth input key configured to output a fourth analog signal as a function of force applied to the fourth input key, and a controller configured to output movement data including both direction and magnitude in response to the first, second, third, and fourth analog signals, where the movement data is formatted for presentation to a driver of a computing device.

  • Patent number: 8717202
    Abstract: Illustrative embodiments of force sensitive input devices and methods are disclosed. In at least one embodiment, a force sensitive input device may comprise a button movable along a first axis between a first end position and a second end position, the button including a reflective surface, a resilient component biasing the button toward the first end position, and a reflectance sensor configured to emit light that impinges upon the reflective surface and to measure an amount of the light that is reflected from the reflective surface, wherein the light travels generally parallel to the first axis.
