VibraSom: sistema embarcado de reprodução sonora por meio de vibração para pessoas com deficiência auditiva

Abstract

Sounds are part of the daily life of a listening person, listening to music can be natural, but hearing impaired people do not have the same ability, and thus, this work aims to create a computer system using actuators, in order to to perform the transduction of sounds emitted by a musical instrument in vibrations perceptible to the touch, so that in this way, people with hearing impairment can have a new experience in the scope of music. The system proposed in this work can also be used by listeners who have the intention of complementing the experience with the music, since, it is not only the musical information that we want to transmit, but the multisensory musical experience. The research comprised, initially, in conducting a requirements survey to reach the needs in the creation of the product and help in the modeling of a viable proposal, followed by the detailed study of the components that will compose the prototype, and to verify its possible uses. Subsequently, the prototype on which this study was based was created and evaluated, within the limitations imposed in the context of the COVID-19 pandemic context. Finally, the tests for the legitimation of the idea proved to be satisfactory with regard to the vibrations being perceptible to the touch, as well as the ability to feel different sensations through unbalanced motors as the frequencies vary, showing that the objective of this work has been successfully achieved.
