  Application: BOOMS Object Oriented Music System
  BOOMS was developed by Eli Barzilay for his Masters Thesis while studying at Ben-Gurion University. The BOOMS system was developed as a general application framework for developing editors with support for a combination of structural and regular editing and support for end-user abstraction as a tool to define reusable functions without programming. The framework is implemented in CLOS (the Common Lisp Object System) and features a sophisticated Windows interface. Instantiating the framework to a specific editing domain is a simple task, due to the clean object-oriented design of the framework. While the BOOMS framework is generic, it is most effective when instantiated to domains similar to music composition, where a user incrementally builds a structured object by using a restricted set of commands to combine smaller units into larger ones. The BOOMS framework was instantiated to three domains to illustrate the support an abstraction-enabled structural editor can provide to end users: music composition, arithmetic expressions and editing in a micro-world of colored cubes (GCalc).

  Application: Player Animations express a sense of process and continuity that is difficult to convey through other techniques. Although interfaces can often benefit from animation, User Interface Management Systems (UIMSs) rarely provide the tools necessary to easily support complex, state-dependent application output, such as animations. Here we describe Player, an interface component that facilitates sequencing these animations. One difficulty of integrating animations into interactive systems is that animation scripts typically only work in very specific contexts. Care must be taken to establish the required context prior to executing animation. Player employs a precondition and postcondition-based specification language, and automatically computes which animation scripts should be invoked to establish the necessary state. Player's specification language has been designed to make it easy to express the desired behavior of animation controllers. Since planning can be a time-consuming process inappropriate for interactive systems, Player precompiles the plan-based specification into a state machine that executes far more quickly. Serving as an animation controller, Player hides animation script dependencies from the application. Player has been incorporated into the Persona UIMS, and is currently used in the Peedy application.

• Sony CSL

  Application: LOOM
  Loom is a language and environment for constructing intelligent applications. The heart of Loom is a knowledge representation system that is used to provide deductive support for the declarative portion of the Loom language. Declarative knowledge in Loom consists of definitions, rules, facts, and default rules. A deductive engine called a classifier utilizes forward-chaining, semantic unification and object-oriented truth maintenance technologies in order to compile the declarative knowledge into a network designed to efficiently support on-line deductive query processing.

  Application: Common Music
  Common Music produces sound by transforming a high-level representation of musical structure into a variety of control protocols for sound synthesis and display: MIDI, Csound, Common Lisp Music, Music Kit, C Mix, C Music, M4C, RT, Mix and Common Music Notation. Common Music defines an extensive library of compositional tools and provides a public interface through which the composer may easily modify and extend the system.
