  • Six of the people were experienced piano players, while the other six didn’t know how to play the instrument.
  • Each person was equipped with a device that was strapped onto their right hand, adding a Supernumerary Robotic 3rd Thumb (SR3T) to the right of their little finger – in other words, the robotic thumb was located opposite their existing thumb.
  • It was found that when instructed to perform eight electric-piano-playing tasks, both the experienced and inexperienced volunteers adapted to the thumb within one hour, using it to help perform those tasks.
