Neuma is a speculative, non-verbal communication tool that translates human gestures into sound and light, exploring new ways of expressing emotions and connecting beyond words. Set in a world where language is increasingly overused and distrusted, the concept explores how technology can strengthen emotional connection through embodied interaction.

The wearable uses five sonic archetypes: Flux, Repetition, Friction, Interruption, and Rotation, representing different conversational roles. In Private mode, subtle vibrations provide personal feedback, while Public mode allows two devices to connect. Through gestures such as squeezing, tapping, and rotating, users create a shared audiovisual dialogue shaped by sound and light.

The project followed a Research through Design approach, combining speculative thinking, embodied ideation, and iterative prototyping. We developed prototypes from foam models to Arduino-based wearables, exploring materials such as silicone and TPU to emphasize tactility. User testing with over 35 participants helped refine body placement, gesture-sound interactions, and the overall experience.
