here's some info- Launch ASUS Touchpad Handwriting and a virtual handwriting board will pop up on the desktop. Position your finger anywhere on the touchpad and open the desired program(E.g. MS Word) to record what you're about to write. Use your finger to write any letter or character on the touchpad.
