    The use of computers and associated technology, has promoted the development of more comfortable and efficient hardware devices. Many handicapped people can not access to this technology. As a result, innovative mechanisms have been designed to attend the requirements of these people. One of such mechanisms has been the control through biopotentials. This article presents the construction of a mouse prototype, which allows horizontal displacements in response to left and right ocular movements that are registered by instrumentation amplifiers, processed and microcontrolled.

    Abstract—During the past ten years the Neural Interfaces and brain-computer communication systems area has become an important field for research, in part due to the increasing statistics of motor and sensorial disabilities. The development of these systems and interfaces requires the coordinated work of different areas such as physiology, materials science, instrumentation and signal processing, computational intelligence, mechanics, electronics, robotics, and informatics, among others. They allowed the right integration between the nervous system physiology, the construction of biocompatible electrodes, the acquiring of proper signals for processing, the classification and identification of coded patterns and the design of the actuators elements to finally achieve the goal of the interface. In this review the three basic stages of neural interfaces are shown. This includes: signal acquiring, signal processing and the wide variety of applications with the effectors systems.
