Cannot find any information on how to make objects move when you do a specific motion

I wasn't really sure how to title this but for I am a new developer using Unity and the Oculus SDK and I am trying to figure how to make an object spawn and move when the player makes a fist and punches.  However I cannot find anything on moving objects based on a hand motion. I keep trying to search different things but I am unable to find anything on the topic.  Kind of like a force push kind of thing but the object will spawn when the motion happens and not already be in the scene.  If anyone has any suggestions of things for me to look up I would really appreciate you pointing me in the right direction. I know I have seen this kind of thing in games before but I cannot find any information online about it so I am assuming that I am just not looking for the correct name of it.
