Há já algum tempo que existem vários esforços para desenvolver um sistema de orientação ideal para pessoas com deficiência visual e cegas, com o objetivo de promover a sua mobilidade espacial. O foco está nos displays auditivos e na sua utilização, que já são utilizados há décadas em interfaces de utilizador inovadoras e têm sido amplamente pesquisados. No projeto OIWOB, foi desenvolvido um protótipo de sistema de assistência para utentes cegos e com deficiência visual, que permite recolher informações importantes sobre obstáculos e comunicá-las ao utilizador através de sinais sonoros. No âmbito da presente investigação, foi concebido, implementado e avaliado através de testes auditivos um método de sonificação para o protótipo acima mencionado. Com base em nove classes de objetos de um estudo anterior, foram gerados vários sons através de sÃntese sonora por modulação de frequência. Sete deles foram testados em testes auditivos com vinte participantes, utilizando um simulador auditivo com auralização dinâmica.
