User Interface Management Systems have signigicantly reduced the effort required to build a user interface. However, current systems assume a set of standard "widgets" and make no provisions for defining new ones. This forces the user interface designers to either do without or laboriously build new widgets with code. The Interface Objects Graph is presented as a method for specifying and communicating the design of innteraction objects or widgets. Two sample specifications are presented, one for a secure switch and the other for a two dimensional graphical browser. (Also cross-referenced as CAR-TR-687)
