Ballerina with ALS Controls Digital Avatar Using Brainwaves in Amsterdam Performance

Breanna Olson, a ballerina from Tacoma, Washington, participated in a performance where her brainwaves controlled a digital avatar to execute dance movements. Diagnosed with amyotrophic lateral sclerosis (ALS) two and a half years ago, Olson has three children and trained in ballet, contemporary, and jazz dance since childhood. The event took place at the OBA Theatre in Amsterdam in December.

The technology involved an electroencephalogram (EEG) headset that measured electrical activity from Olson's brain. Developed by Japanese firm Dentsu Labs in collaboration with NTT, the system converted her imagined motor signals into real-time instructions for the mixed-reality avatar. BBC reported the performance as the first of its kind.

Olson described the process as requiring focus to isolate muscle signals amid surrounding noise. She lives with ALS, a motor neuron disease that progressively weakens muscles, affecting speech, swallowing, and breathing, with no known cure. The project, named Waves of Will, aims to restore personal expression for those with motor-degenerative conditions.

Technological Development Dentsu Labs and NTT created the brainwave interface to make such technology more accessible, as many existing systems are expensive. Naoki Tanaka, chief creative officer at Dentsu Lab, stated the initiative addresses barriers to brainwave research worldwide. Mariko Nakamura of NTT indicated potential applications for devices like wheelchairs or remote controls. The performance allowed Olson to convey specific dance movements through her avatar in real time. Olson told BBC the experience felt exhilarating and magical, re-establishing a sense of connection eroded by her condition. She believes the technology has potential for others with disabilities. >

"This is a new way of expression.

Broader Context Scientists are exploring brain-computer interfaces to help individuals with physical or mental deterioration participate in activities. Olson expressed hope that her involvement could inspire others with ALS, emphasizing the power of the mind. She aims to provide hope and demonstrate untapped human potential despite the disease's challenges.
