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.
