The performance, held at the OBA Theatre in Amsterdam in December, was described at the time as the "first of its kind".

It saw Breanna use an electroencephalogram (or EEG) headset, developed by Japanese tech firm Dentsu Lab in collaboration with data company NTT, to capture her brain activity and specific motor signals associated with imagining certain dance movements.

A brainwave interface translating these signals into computer instructions then allowed her to convey which of these movements she wanted her mixed-reality avatar to dance in real-time.
