Sound Effects in Theatre: Towards Actor-Controlled IoS Devices for Interactive Performance

This paper investigates the under-explored potential of actor-controlled sound effects in live theatre using Internet of Sound (IoS) technologies. A technical case study was conducted through a sound design workshop with live actors. Participants were introduced to IoS devices as novel means to trigger and manipulate both pre-recorded samples and procedural audio models in real time. The devices were built using Arduino MKR 1010 Wi-Fi microcontrollers, incorporating a range of sensors, including accelerometers, circular potentiometers, force sensitive resistors, photoresistors. Participant feedback emphasised the importance of early integration into rehearsals, cross-departmental collaboration, and reliability. These findings inform the design of future IoS-enabled performances, with a live deployment planned for December 2025.
