Natural Interaction to Support Teaching Activities in Health

In the field of human-computer interaction, Natural Interaction methods has been gaining importance because they provide communication between user and machine through an easy and intuitive way, by interpreting the natural actions of persons. In the development of Virtual Reality systems for health, there is a need to produce forms of interaction that are similar to the commonly performed by people in daily activities. Because of its intuitive features, the Natural Interaction can perform an important role in this scenario. It is important to emphasize that some natural behaviors can be of cultural origin, creating the need to identify the specific features target audience in interaction with applications that provide natural interfaces. The general goal of paper is to discuss a set of techniques for Natural Interaction by gestures for use in tracking systems by optical devices to support professors in health teaching activities.
