Journalists discovered an unusual patent application filed by the Embraer company in 2016, a patent was granted in 2022. The document describes “brain stimulation” technology that “provides a sense of well-being (or peace). Why is this necessary? Embraer notes that many people become anxious during long journeys and can be helped.
The system Embraer proposes has a digital video camera that scans the passenger’s face and then transmits information to analyze the person’s emotional state. Accordingly, the passenger can be offered a non-invasive brain stimulation technique using current, magnetic field or ultrasound.
The affected passenger is expected to relax and enjoy the long journey.
As The Verge notes, methods using magnetic or electrical stimulation for depression already exist, and the possibility of using them for other mental health disorders is being evaluated.
