Aplicação de um dispositivo de comunicação vibrotátil no contexto do karatê para atletas surdos

Abstract

This dissertation presents the development and preliminary evaluation of a vibrotactile device as an alternative communication tool for deaf athletes during Karate practice. The study stems from the need to overcome communication barriers that hinder the inclusion of individuals with hearing impairments in sports that require quick responses to commands, such as Karate. The prototype was adapted from a model developed in a laboratory setting, with physical, electronic, and software modifications to meet the specific application’s requirements. Three laboratory tests were conducted, focusing on the perception and identification of vibratory commands, application in Kihon exercises, and Kumite simulation. The results showed accuracy rates above 90% in signal interpretation and good fluidity in motor responses, indicating the feasibility of the system as a means of nonverbal communication. It is concluded that vibrotactile technology may enhance accessibility and inclusion for deaf athletes, with potential future applications across other sports modalities and physical activity contexts.
