Casey Harrell used a brain–computer interface at home to communicate and operate his computer without researchers present.
A documented follow-up with the same participant, not independent replication. The measurements belong to their respective studies.
From researcher-supported conversation to home use without researchers present.
The same participant. An investigational implant. Caregiver setup still needed.The study reported 97.5% word accuracy after further training, sustained over 8.4 months.
One participant, implanted electrodes, and specialist support. This is not a broadly available treatment.
Inspect source ↗The study reported more than 3,800 hours of home use by one participant, including communication and computer access, without researchers present.
One participant with an implanted investigational device. Caregivers still helped set up the system. This is not general clinical availability or independent replication.
Inspect source ↗Test safety and reliability with more participants; reduce the equipment and support needed for daily use.
An open research direction, not a promised outcome.
