Brain-Computer Interfaces

In research, users genuinely feel touch through nerve-interfaced prosthetics, and it measurably improves control. Commercially available advanced prosthetics offer excellent grip patterns but only limited or no true sensory feedback, and cost is a major barrier.

For a small number of clinical trial participants, yes — and it is life-changing. Implanted interfaces let people with paralysis move cursors, type and control devices by intent. For everyone else, non-invasive consumer headsets remain crude: a few commands, lots of calibration.
