Abstract: A human-computer interface system and methods for providing intelligent, adaptive, multimodal interaction with users while accomplishing tasks on their behalf in some particular domain or combination of domains. Specifically, this system accepts user input via natural language text, mouse actions, human speech, whistles, gestures, pedal movements, facial or postural changes, and conveys results via natural language text, automatically-generated speech, and displays of graphs, tables, animation, video, and mechanical and chemical effectors that convey heat, tactile sensation, taste and smell.

Abstract: A system and method for representing and solving problems allows a user to enter objects and attributes, and to form a table of at least two dimensions having object-attribute pairs. An object hierarchy is then implemented using the entered objects. A score is maintained reflecting how closely the constraints of a particular problem are to being satisfied and the degree of progress in the direction of stated objectives of the problem.

Abstract: A system and method for representing and solving problems which allows a user to enter objects and attributes, and to form a table of at least two dimensions having object-attributes pairs. An object hierarchy is then implemented using the entered objects. The system allows the user to enter constructs to represent relationships among the object-attribute pairs, and also to enter objectives and constraints for the problem. The system allows the user to solve the problem manually or automatically by the system. A score is maintained reflecting how closely the constraints of a problem are to being satisfied and the degree of progress in the direction of the stated objectives of the problem. The system allows representation of hybrid numerical and symbolic problems, and provides solutions to linear or non-linear, discrete or continuous, and feasible or non-feasible constraint satisfaction and optimization problems.
