VILLA MORENO, Adriana; GARCIA QUIROZ, Felipe; CASTANO JARAMILLO, Paula  and  LONDONO JARAMILLO, Nathalia. DESARROLLO DE UN SISTEMA DE AUDICIÓN VIBROTÁCTIL PARA EL ACCESO A LA MÚSICA: FASE I. Rev. ing. biomed. [online]. 2007, vol.1, n.1, pp.60-65. ISSN 1909-9762.

The sense of touch transmits not only isolated tactile sensations also information that can be processed at the cerebral cortex in a similar way as it is in the brain areas for audition or vision. Both vibratile and electrical stimuli have been used for tactile stimulation devices, and the former was chosen for the system presented. The tactile auditory-substitution systems have focused on communication skills, but this work pretends the construction of a device for developing musical and artistic skills. These should be reflected in the capacity to identify musical pieces through tactile stimulation. The graphical user interface of the system was programmed using the virtual instrumentation software LabVIEW 7.0. It includes tools for the learning of the system, which were developed to help increasing the sensitivity of the user. Besides, to ensure a clear association with music theory and acoustic concepts some visual feedback systems were implemented.
