In VR, a butler is a type of haptic interface. In essence, it is a robot that attempts to position itself in the way, whenever a user tries to interact with a virtual object. Thus, when they reach out to grasp the object, what they are feeling is the surface of the butler robot instead.

The obvious limitations are, if you only have one butler, you can only feel one object at a time. Also, you are only ever feeling what the butler feels like, not what the object should itself feel like. This can lead to weird sensations, such as soft, furry glass.
