Interacting with a tridimensional scene generally relies on input devices such as keyboard and mouse. This interaction model is constrained and unnatural, besides being incoherent with the objective of many interactive 3d simulations, which is to isolate the user from reality by producing realistic imagery that comes close to what is conceived in reality. Even when making use of this technology, the desired isolation is curtailed by this artificial interaction model. For that matter, a more convenient, natural and intuitive way of interacting with the virtual environment is needed. The user would benefit from directly manipulating the scene with his own hands as he would in the real world, which would strengthen the sense of presence offered by the application. This project objectives the visualization and simulation of a realistic tridimensional hand model, which is able to interact with a virtual scene. In other words, the model responds to collision with 3d primitives, such as spheres and boxes. It is expected, in the future, the development of an interaction model based on computer vision which uses this project’s final product and ultimately addresses the aforementioned problem.
