Abstract: A method and system for interactive communication in sign language using computer animation. In one aspect, a user interface is provided with a first activity area and a second activity area. A three-dimensional avatar configured to communicate using sign language is displayed between the first activity area and the second activity area. In response to the user selection of a respective one of the activity areas, the avatar is directed to sign an expression associated with the selected activity area. In another aspect, a method of teaching mathematics using sign language is provided. According to another aspect, a method of animating a signed communication is provided. In another aspect, a method of creating an animation of a sign language expression is provided.

Abstract: A method and system of configuring a three-dimensional model using a keyboard. A three-dimensional model is provided that is configurable about a plurality of degrees of freedom in which each respective degree of freedom is associated with a value representing a magnitude of movement from a neutral position. At least one key on a keyboard is associated with each respective degree of freedom of the three-dimensional model. In response to the selection of at least one key on the keyboard, identifying the respective degree of freedom associated with the keyboard selection and adjusting the value associated with the identified degree of freedom. Although keyboard based, this interface allows the user to obtain a desired configuration of the three-dimensional model without prior knowledge of any 3D software and without selecting and applying transformations using a graphical user interface.
