    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.
