Force sensitive input devices and methods
First Claim
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.
