The model includes an audio-tactile algorithm that transforms monophonic music into concrete stimuli based upon vibration using “tactile illusions.”

An audio-tactile algorithm developed by University of Malaga researchers communicates melodic info through vibration.

A ground-breaking model established by professionals from the Department of Electronics at the University of Malaga and members of the R&D group “Electronics for Instrumentation and Systems,” will permit those with hearing loss to listen to music through the sense of touch.

It includes an audio-tactile algorithm that changes monophonic music into concrete stimuli based upon vibration using “tactile illusions.” According to the scientists, “It’s like ‘hacking’ the nervous system to receive a different response to the real stimulus sent.”

“What we want to achieve in the long term is for people who do not hear to be able to ‘listen’ to music”, ensures scientist Paul Remache, the primary author of this paper, who demands the power of music to affect state of mind, along with its possibilities as a treatment for mental illness and treatment of discomfort.

The scientists forecast that this will result in a portable terminal that might be given a show given that this model will be quickly transferable to technological gadgets like smart devices.

Mapping music

This young scientist, dealing with teachers Andr és Trujillo and Fernando Vidal from the UMA, established an algorithm that can change musical functions and structures drawn from MIDI files–Musical Instrument Digital Interface– into “vibrotactile stimuli.”

“It’s something similar to mapping music”, discusses Remache, who includes that this is possible due to the fact that this kind of file not just can be played and produce noise, however likewise supply “symbolic representations”.

Controlling vibrations

Current designs do not call for the correspondence in between the psychological reaction to music and the vibrotactile variation of it. In view of this, these engineers of the UMA propose a plan of the “tactile illusions” in order to enhance and extend the spectrum of musical functions, including characteristics to the vibration in the kind of motion, switches, and place.

“It is a challenging process since the perceptible frequency range of the skin is lower than that of the auditory system, which may cause the loss of some musical features”, they discuss.

Different psychological reaction

The outcomes of the very first experiments, in which more than fifty volunteers got involved, show that the plan of “tactile illusions” generates more favorable than unfavorable feelings. They are likewise viewed as more reasonable and revitalizing than the audio, provoking a various psychological reaction from that of the initial music.

Smart instrumentation and application in health care

This very first model existed in the 11 th International Workshop on Haptic & & Audio Interaction Design (United Kingdom)– the most significant global occasion concentrated on these locations of research study– after being released in the clinical journal LNCS At present, the scientists of the UMA are dealing with a 2nd design and continuing with the experiments.

The research study is the item of Paul Remache’s doctoral thesis and becomes part of the National Plan task “Smart instrumentations and application in healthcare.”
