Help! Need a USB stylus/pen for xmas!

Okay. So my dad bought a fuckin coffee table which is basically a 42" flatscreen TV with an xbox attached but layed down all flat like.

So, for xmas, I want to buy him a stylus (or tablet pen) which will be able to be calibrated to the TV dimensions and allow him to operate it as a PC, but by tapping on it with a stick (like a monkey) instead of by using a mouse and a keyboard.

I am having considerable trouble finding this kind of product, and sincerely hope reddit can help!

Thankyou
