[PATCH v2 0/3] input: appletouch: fixes for jagged/uneven cursor movement

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



These patches address some usability issues by dialing back the fuzz and threshold parameters, by implementing some smoothing for the sensor data and by discarding movements that directly coincide with a change in the number of fingers detected on the touchpad.

Changes since last time:

1/3: Remove extraneous cleanup - I'll submit a separate patch another day
2/3: Apply smoothing to the sensor data before position calculation, eliminating the need to toss values based on a threshold; simplify formula for averaging with prior values
