# Hand Touch / Trigger

## Hand Touch Event

Hand Touch Events work by adding this component to the root of any rigidbody and these events will get called when the hand(s) begin/end collision touching an object. This component reacts to solid collision with the hand (OnCollisionEnter), use the [Hand Trigger Area](#hand-trigger-area) for objects reacting within a trigger collider
