This paper describes the design and implementation process of a system prototype that uses a platform with two degrees of freedom, to indicate the direction of the line of sight of an individual in real time, through his helmet movement sensing, having as a reference a system that can change its heading and tilt. For this, two inertial measurement units (IMU)are used, whit low cost and 9 degrees of freedom, to which sensory fusion of the values obtained from the accelerometers, magnetometers and gyroscopes is applied, through a Angular Kalman filter for each IMU. Which allows to determine the tilt and orientation of the helmet and the reference system, then calculate the differential and based on this value, adjust the angles of PITCH and YAW of a platform that follows the helmet user s line of view in real time. In the first section, an introduction is made, presenting the importance of the prototype to implement, the State of the art by Consulting similar investigations papers, and objectives are defined. The following section explains the theoretical foundations required for implementation. After that, in the third section, the main design parameters and general specifications of the prototype are determined. Then in the fourth section, its implementation is explained, and finally, in Sections 5 and 6, the tests carried out and results obtained are described, summarizing the goals achieved.
