Zen by Z
HP Omnicept Lab — mind training, in the zone
A headset that feels your heartbeat — and a world that breathes with you.
Zen by Z, a biofeedback demo for the HP Omnicept headset, shown at GDC. The idea: let the body drive the world. Heart rate, eye tracking and cognitive load steer a mind-training journey — calm forest, floating rock, a controlled disruption, then recovery. Designed, built and coded in Unity.
Designing the calm
…and the disruption
The storyboard — disrupt, then recover

Screen choreography — forest, disruption, recovery

The recovery factor — breath brings you back
Built, not just drawn
Unity, live, solo

The disruption — spiders, red light, gaze burn

The code — cognitive load as a game variable
All projects are always team work. In this team I helped build the vision, built the prototypes, and presented with Dr Erika Siegel at the Game Developers Conference.
This Unity demonstrator space was custom-built to show the cognitive-loading simulation potential — a collaboration with Dr Siegel and Tico Ballagas, who guided the biofeedback science.
