Each student wears a head-mount display that immerses them in the 3D CAD models for the ship. Steve pedagogical agents serve as their team-mates or tutors. Jack s tutor is the blue PACC operator circled above. The 3D CAD setting and equipment simulations are used by the students and the agents together. Students talk to the tutor to try doing part of the task.
Speech acts are part of the instruction.
Students ask about the task using speech recognition. The tutor agent can monitor the student s view and actions in the world, and the effects are promulgated in the simulation. Tasks can be resumed by the tutor. Students can talk to their agent team-mates. Jill is instructed in another part of the ship, the engine room.
