Sensory augmentation through tissue conduction

One hundred volunteers have undergone short (5 min) listening tests in a novel multi-transducer bone-and-tissue conduction apparatus for spatial audio. The subjects subsequently described their experiences in an unstructured qualitative elicitation exercise. Their responses were aggregated to identify key themes and differences. Emergent themes are: enjoyable, informative, spatial and strange. Tactile supplementation of spatial audio display was noted in a positive light. We note that some spatial attributes are more perceptible than others. The implications for perceptual augmentation are discussed, particularly in relation to conductive hearing deficits. We conclude that the technique has potential for development and discusses future research directions.
