3、Applications,Challenges,and Policy Options What GAO found Brain-computer interfaces(BCI)are electronic systemseither implanted in the brain or worn on the headthat let people control computers,robots,or other devices using brain signals.In clinical trials,BCIs have helped people with severe disabili

4、ties communicate and use robotic limbs,though these BCIs are not yet on the market.Researchers are also investigatingand companies are investing heavily in BCIs for the workplace,national defense,and consumer uses.Experts identified several challenges to BCI development and use,including:Uncertainti

5、es in data ownership and control.Without a unified privacy framework for all BCIs,or standards on data ownership and control,companies that develop and sell BCIs may have access to sensitive brain signal data without users understanding or consent.In addition,agreements between developers and users

6、may be predatory or unclear.Potential loss of access or support.Experts told us that users may lose access to the benefits of their implanted BCIs for various reasons.For example,some clinical trial participants have had a BCI removed because there were no funds or medical support provided after the
