How a dancer with ALS used brainwaves to perform live

The problem and a simple idea

There’s a quiet assumption baked into most tech: users can move their hands. Swipe, type, click. But an estimated 200 million people worldwide live with serious physical disabilities that make those gestures impossible. Dentsu Lab’s Project Humanity treats that not as a medical puzzle but as an interface problem — if the body can’t be the output, find a different channel. It has been reported that the team began by reading minute muscle signals with EMG sensors and mapping that activity into a full-body digital avatar.

From sensors to a general-purpose digital body

The clever bit is not just animating a likeness. The avatar becomes a control surface — a general-purpose body in virtual space that can drive games, productivity tools or creative apps. The raw biological signals are translated into intended motion, making intention legible when the body cannot speak. Trials in e‑sports allegedly showed that performance differences dissolve once everyone shares the same layer of interaction. So: why should physical limitation equal digital exclusion?

A live proof of expression in Amsterdam

If the demos proved the idea, "Waves of Will" proved the feeling. It has been reported that on 10 December 2025 in Amsterdam, in collaboration with NTT Inc., Dentsu Lab staged a live performance starring dancer Breanna Olson, who has ALS. The system shifted from EMG to brainwave detection: Breanna’s neural signals were translated in real time into choreography performed by her avatar on stage. She allegedly called the experience “exhilarating” and “magical.” Watching your mind take the floor — that’s the emotional heart of this work. It’s not just accessibility; it’s reclamation.

This sits squarely in the larger wave of brain‑computer interface work and raises a simple, human question: what happens when we decouple intent from anatomy? For many, this is more than novelty or Metaverse talk — it’s a route back to expression, community and the stage.
