3D Audio Augmented Reality

As part of an innovative project led by the Musée de la Civilisation de Québec, the goal was to create immersive, augmented, and interactive 3D sound environments — delivering a unique auditory experience that reacts in real time to each visitor’s geolocation and head orientation.

Cocktails Solutions Inc. was commissioned to design a custom embedded solution integrated into audio headsets. Each headset was equipped with a UWB (Ultra-Wideband) positioning sensor, an inertial measurement unit (IMU), and a microcontroller capable of transmitting the head’s position and orientation in real time via USB-C in an indoor environment.

Our team focused specifically on:

• developing the embedded electronics inside the headset,
• programming the microcontroller firmware,
• building a web service and web interface to visualize the real-time position, orientation, and status of each headset,
• designing the UWB layout and antenna positioning to support up to 75 concurrent users in a single exhibition space,
• ensuring headset maintenance and operational reliability.

This project showcases Cocktails Solutions’ multidisciplinary approach, combining embedded electronics, software, IoT, and web technologies to power next-generation interactive experiences.

The Musée de la Civilisation de Québec continues to use this equipment in various exhibitions such as Sur paroles. Le son du rap queb, Trouver refuge, and future installations.
