      Abstract

      Choral activities are generally led by a conductor who uses visual cues and non-verbal instructions to drive the performance. Song dynamics are generally well rehearsed however live performances may necessitate unrehearsed messages in order to correct errors or to introduce dynamics in response to external factors. These messages are communicated by the choir master just-in-time, to which however, visually impaired choristers have no access. This paper outlines an investigation into how technology can contribute to this end while presenting a solution which adopts optoelectronic devices for gesture recognition, real-time communication protocols and over-the-air haptic-feedback to enable participation while minimising adoption barriers via intuitive and low-friction interaction. Insights from both qualitative and quantitative techniques will be presented along with techniques used to understand, assess and evaluate the domain in an iterative series of interventions.

        Early but not late-blindness leads to enhanced auditory perception.

        The notion that blindness leads to superior non-visual abilities has been postulated for centuries. Compared to sighted individuals, blind individuals show different patterns of brain activation when performing auditory tasks. To date, no study has controlled for musical experience, which is known to influence auditory skills. The present study tested 33 blind (11 congenital, 11 early-blind, 11 late-blind) participants and 33 matched sighted controls. We showed that the performance of blind participants was better than that of sighted participants on a range of auditory perception tasks, even when musical experience was controlled for. This advantage was observed only for individuals who became blind early in life, and was even more pronounced for individuals who were blind from birth. Years of blindness did not predict task performance. Here, we provide compelling evidence that superior auditory abilities in blind individuals are not explained by musical experience alone. These results have implications for the development of sensory substitution devices, particularly for late-blind individuals.
