Resolución de localización espacial háptica mediante estimulación eléctrica en la yema de los dedos.

The electrical stimulation has demonstrated its usefulness as actuators in the development of haptic devices, since it presents the possibility of varying parameters such as frequency and current intensity in different regions of the human body, producing different stimuli in the different mechanoreceptor organs. When used on the fingertips, it allows the distribution of the signals to electrodes framed in a matrix type arrangement, in order to produce different sensations in the user. This work describes, by means of a prototype based on electrical stimulation, the resolution for the purpose of haptic spatial location. The results of a first experimentation with healthy users are presented. [ABSTRACT FROM AUTHOR]
