Scientists have developed a prototype of a new technology that allows deaf people to hear music through touch.
The prototype, described in the journal LNCS , uses "haptic illusion," an algorithm that transforms monophonic music into vibration-based tactile stimuli.
"This is like 'hacking' the nervous system to get a different response to the actual stimulus delivered," researchers from Spain's University of Malaga said in a statement.
In this study, the researchers developed an algorithm that converts musical features and compositions into "kinetic stimuli."
The algorithm extracts musical features and structures from a Musical Instrument Digital Interface (MIDI) file to create a "symbolic representation" of the sound.
"Cartography is like music," explains study author Paul Remach.
A study involving more than 50 volunteers suggested that the "tactile illusion" line evoked more negative than positive emotions in participants, resulting in different emotional responses to the original music.
"Although musical features such as tempo, tempo, and melody are more commonly recognized as tactile illusions, they evoke a different emotional response than the original sound," the scientists wrote in the study.
In future research, the scientists hope to refine and expand the range of musical features processed by the algorithm, including changes in the direction and location of vibrations.
"This is a difficult process because the bandwidth perceived by the skin is lower than that of the auditory organ, and this may lead to the loss of some musical properties," the researchers explained.
They believe the prototype could lead to a portable terminal that could easily be moved to a tech device, such as a smartphone, that could be taken to concerts.
