Previously, it recognized a new finger when a low sensor reading is followed by a high sensor reading. The new method checks for 'humps' in the sensor readings, so there doesn't necessarily have to be a low sensor between two high sensors for two fingers to be triggered. This allows detecting presence of two fingers on the touchpad even when they touch each other. - Change absolute coordinate calculation to us to get rid of "jumps". Instead of using full value from a sensor once it passes the threshold subtract theshold value from the reading. - Allow adjusting threshold value via module parameter. The patch doesn't seem to affect the Powerbooks but does greatly improve the touchpad behaviour on the MacBooks. Signed-off-by: Jason Parekh Signed-off-by: Stelian Pop Signed-off-by: Dmitry Torokhov
