By carefully watching the motion of a person’s arm, the system determines what the intention of that arm is — to pick up an object, for example — and can tell when that intention has changed or been disturbed.
“We call it a psychic robot,” said lead author Justin Horowitz in a news release. “If you know how someone is moving and what the disturbance is, you can tell the underlying intent — which means we could use this algorithm to design machines that could correct the course of a swerving car or help a stroke patient with spasticity.”
