LEA is an intelligent, rule-based, interactive agent that maximizes the benefits of human-computer interaction in task-oriented environments
LEA allows the user to use natural speech and gestures for natural interaction
LEA provides highly interactive, situation aware, expert process knowledge that can significantly improve user productivity and allow a more natural and effective interface
LEA collaboration framework enables control of multiple remote or local entities and provides effective collaboration between multiple users and synthetic entities
LEA provides a new concept in automated course development for interactive web-based learning. LEA can work as both a course development agent and an intelligent instructor.
- Hierarchical rule-based expert system Natural Language Agent
- LEA can create new objects and modify the properties of existing objects in the VE
- Allows the use of fuzzy linguistic numbers (such as low, medium, and high) to set or change objects' properties
- Understanding of non-verbal commands such as gestures, pointing, looking, and touching
- Interactive generation of synthesized speech messages in response to user
- Innovative hybrid single word/continuous dictation approach for recognition provides over 98% accuracy
- LEA can control multiple remote or local networked VE objects
- User-defined process learning feature
- Rules can be triggered based on user actions in the VE
- Enhanced collaboration capabilities
- Enhanced reasoning capabilities including the ability to answer questions, provide explanations and assistance, and alert the user to problems in task-oriented environments
- Effective knowledge capture, dissemination, and renewal using natural language and automatic extraction of concepts and relationships
- Ease of integration with existing object-oriented systems
- Ease of maintenance and customization to specific applications
