 #### Configuring NearInteractionTouchable
 When configuring your _Near Interaction Touchable_, make sure to configure the _localForward_ parameter to point out of the front of the button or other object you wish to make touchable. Also make sure that the touchable's _bounds_ matches the bounds of your touchable object. 
 
 Other parameters:
 
 - eventsToReceive - if set to Touch, the object will receive _OnTouchDown_ _OnTouchUpdate_ and _OnTouchUp_ events. If set to pointer, the object will receive _OnPointerDown_ and _OnPointerUp_ events.
 - touchableSurface - use this to help compute the bounds of the surface. Bounds will automatically adjust to the attached BoxCollider, UnityUI element, or can be set manually by adjusting _bounds_.
+- visuals - Game Object used to render finger tip visual (the ring on finger, by default)
+- line - optional line to draw from fingertip to the active input surface.
