Contract amendment mechanism in a virtual world
Abstract:
A method for amending a contract in a virtual world may include presenting an online chat option in response to another user's avatar coming within a predetermined proximity range of an avatar of the user and in response to the other user's avatar and the user's avatar having previously entered into a contract in the virtual world. The method may also include recording the online chat between the users to define an amendment to the contract in response to the online chat option being selected. The method may further include appending the amendment to contracting terms in a contract object in response to acceptance of the amendment by the users.
