    Direct manipulation has proven to be an excellent method for interacting with geometric objects. Unfortunately, traditional approaches for implementing direct manipulation suffer from a lack of generality, requiring the system designer to hand craft interfaces to different types of objects. In this paper we present differential manipulation, a new paradigm for direct manipulation of geometric objects. By interpreting graphical entities as physical objects, we obtain a uniform interface to a wide variety of geometric objects, making it simple to add new types of complicated or compound objects. Geometric constraints fit neatly into the paradigm.
