Sliding structure location on a pointing device |
摘要 |
A pointing device has a pointing device surface and a sliding structure that moves with respect to the pointing device surface. A detector outputs a value that varies as the sliding structure moves with respect to the pointing device surface. A controller estimates the sliding structure location on the pointing device surface by calculating an approximate distance. The approximate distance is calculated by multiplying a measured differential of the value times a conversion constant. The controller adjusts the approximate distance to take into account non-linearity of the measured differential. |
