发明名称 Force sensitive input devices and methods
摘要 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.

主权项 1. An input device comprising: 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 calculate a first vector having a first magnitude based on a value of the first analog signal, calculate a second vector having a second magnitude based on a value of the second analog signal, calculate a third vector having a third magnitude based on a value of the third analog signal, calculate a fourth vector having a fourth magnitude based on a value of the fourth analog signal, and output movement data including both direction and magnitude that represent a vector addition of the first, second, third, and fourth vectors, the movement data being formatted for presentation to a driver of a computing device.
