                         mouse called Guai{\'a}. The mathematical grounds of the sensor 
                         device are described. This device senses the rotation of its body 
                         on the work surface where it is handled, and surpasses some 
                         deficiencies of common mouses. It is a candidate for utilization 
                         in low cost virtual reality systems, where a third degree of 
                         freedom is indicated for the control in 3D represented spaces; and 
                         for 2D painting systems, where the control of the brush can be 
                         enhanced with the controlled rotation.",
