need help hand tracking mouse

edit

hello guys, I'm working on hand recognition method with finger counting and decide to add a trackbar for inputing the value that determine how the mouse action react when the hand shown the value that has been set on input trackbar.

but no matter how much value i set on trackbar will always do left click, even i set different value
