Android seekbar with parallax progress

view story

http://stackoverflow.com – I spent lot of time with customizing vertical seekbar that works on android 2, and Ive found this awesome solution by Andro Selva. https://github.com/AndroSelva/Vertical-SeekBar-Android What I actually want to do with that, is that the seeking is parallax, that means the finger that swipes the vertical bar goes faster than actual seekbar. I want to do that I need to do par example 3 full screen swipes to get the thumb to maximum of the seekbar and 3 times to back to the minimum. This is because I need very precise seeking with the seekbar. Any ideas how to acomplish that? Thank you Jenda (HowTos)
