Basic 3D interaction techniques in Augmented Reality

Information technology currently supports the development of human interaction with virtual environment, this development will continue in developing in the form of Human Computer Interaction (HCI). In this study, how the environment 3D virtual computer should be able to recognize human hand as part as virtual object, so it can interact with virtual environment. HCI is a study in which the relationship between humans and computing technology and how computers are designed for easy to use by human, more practical and more intuitive. HCI emphasizes how human interaction with computer technology. This research is using use 3D transformation to digital objects used in computer graphics, transformation of the basis for the movement of digital objects in interaction technique in virtual environment to interact between human hand and virtual object. Tracker is needed in virtual interaction by using Augmented Reality (AR), the problem that arise in AR is how to read marker, so it can display a virtual object that has been computed before, basically is how to read the geometry model of human hand, then the result from the processing of the human hand model geometry is used as a marker, so it can interact with a virtual environment on AR as one of the HCI model implementation. This process is intended for the movement of human hands that have been read as a virtual object can communicate virtually using image processing.
