Human communication always used gestures, movements and ex- pressions as oral language support. Certain gestures are so commonly used around the world that are understood throughout different cultures and times, such as a wave or thumbs up. Natural Interaction is a way to apply this concept to user interfaces in computer systems. In this paper we discuss about the use of Natural Interaction features in a telemedicine system. More specifically, we demonstrate the use of natural interaction interfaces for control and manipula- tion of 3D objects inside Arthron tool. Arthron is a telemedicine tool used for surgery transmissions. Keywords: Human Computer Interaction, Natural Interaction, Telemedicine. 1 Introduction Making a brief retrospect we can identify the evolution of these devices through the command-based languages, through the graphical user interfaces (GUIs), and finally the direct manipulation with the advent of the use of the pointers (mouse). From the rise of touch screens, the use of cameras in the analysis of user actions and the creation of devices that allow us to use technology more easily. For example, the Kinect that enables us to think about the development of more sophisticated and natural user interfaces. The Natural Interaction (NI) studies ways that humans can interact through humans five senses, be that with gestures, voice commands, corporal expressions or human body parts detection and identification [1,2,3,4]. Natural User Interface or NUI is the used to refer to a user interface that applies concepts of natural interaction in its construction [5]. NUI is considered a new inte- raction paradigm, since the old and known WIMP (Window, Icon, Menu, Pointer) use concepts of interaction with devices themselves, i.e., there is the use of keyboard or mouse to access any part of the graphic interface, what is not considered as natural interaction, since using such hardware is not part of the naturalness of human being.
