A standalone headset syncs scents to 360 video
A virtual reality experience synchronises scent release with zero latency on a standalone headset.

The project
Guerlain presents an interactive virtual reality installation combining a 360° experience with synchronized fragrance diffusion. The setup required controller-free navigation and wireless synchronization between the headset and the scents. A dedicated, gaze-controlled application streams the video and controls the olfactory unit via Bluetooth. Two fragrances are triggered at the exact timing of the video, with no perceptible latency. The system ensures immediate automatic reconnection of the diffuser in the event of sleep mode or signal loss.

The challenge
The audience does not handle any controllers. The interface had to respond to gaze alone, while the video stream triggered targeted scents. If the wireless connection dropped or diffusion was delayed, the sensory illusion would instantly collapse.
Our approach
The visitor puts on a standalone headset. In front of them, the home screen activates after three seconds of gaze fixation on the button stylized according to the Guerlain brand guidelines. We developed the application in Unity, integrating a 360° experience player and a 180° mask. To synchronize the perfumes, the headset communicates via Bluetooth Low Energy with the diffuser. Our code controls the opening of the olfactory nozzles to diffuse the "Nérolie plein sud" and "Herbe troublante" fragrances for exactly seven seconds. In case of standby mode or signal loss, the system manages alerts and reconnects automatically.
