Agents as tutors in augmented reality
(2003-01-01) Álvarez, N.; Trefftz, H.; Universidad EAFIT. Departamento de Ingeniería de Sistemas; I+D+I en Tecnologías de la Información y las Comunicaciones
Interaction between virtual entities and human beings should be similar to the normal interaction between human beings. Verbal interaction is the usual way of interaction among humans, but the interfaces that allow verbal communication between a human being and an agent (virtual human) have a limited vocabulary, need a lot of training and are expensive. In this paper we propose an Augmented Reality System with an unidirectional interface between an agent and a person. By using gestures, animations and adequate texts the agent can show a user how to perform a simple task. We hope that the tests to be conducted will show how useful this unidirectional interface is.
