trying to draw a line from player hands

so at the moment i am working on a school project with a couple of people and what i have been trying is to draw a line in front of the players hands in game. but so far i have not succeeded in getting the correct hand position.
As of now it only draws a line from where the hand is relative so at the bottom where my feets are.

is there a way to get the oculus touch position? and use that as a position to start the drawing from? if so i would love to hear it.
