    Abstract: An interactive language instruction system employs a setting and characters with which a learner can interact with verbal and text communication. The learner moves through an environment simulating a cultural setting appropriate for the language being learned. Interaction with characters is determined by a skill level matrix to provide varying levels of difficulty. A visual dictionary allows querying of depicted objects in the environment for verbal and text definitions as well as testing for skill determination.
