STREB & Pendaphonics

Pendaphonics is an interactive physical-digital-sonic environment and system that engages users in various forms of individual, collaborative, group and distributed interactions. This system was developed with colleagues at Aalborg University as a trans-disciplinary research endeavor that presents a strategy for the design and evaluation of low-cost, flexible, distributed and physically interactive sonic environments. Diverse implementations and extensions of the Pendaphonics system have now been installed, demonstrated and experienced by hundreds of people.

Through the use of the cyclic motion of a pendulum’s simple harmonic oscillation, Pendaphonics presents a repeated “invitational interface” encouraging users to interact with a 3-D physical-digital-sonic environment. On various occasions, Pendaphonics has been implemented as: a compositional and choreographic tool; an educational exhibit and classroom manipulative; and as an interface that facilitates playful interaction, exploration, discovery and creativity.
