RESUMO
Tracking systems are a fundamental technology in virtual reality systems. They provide a continuous detection of the position and orientation of markers or specific objects that the user employs to interact with the system. One of the technologies most commonly used to implement these types of systems is the optical tracking, which allows the users to have more freedom in their movements because it does not need cables or mechanical elements that can restrict or hinder the immersion sensation that is tried to create in the interaction with virtual reality environments. This work presents the construction and implementation of an input device that is based on optical tracking that is used for interaction with semiimmersive virtual reality applications on ordinary desktop environments. This device has the capability to get the six degrees of freedom of the movements made by a set of markers that are controlled by the user hand. Based on the six degrees of freedom recovered, the device is complemented with the ability to emit events that allow the interaction of the user with the application. Finally, an application is presented for demonstrating the use of the generated events and the performance of our device.
