Password-Protected Mind-Reading Brain Implant Developed
Scientists have built a 'mind-reading' device called a brain-computer interface, or BCI.
This device lets the brain talk to computers.
The BCI works by decoding thoughts, turning them into words.
To make sure it only decodes what you want it to, the BCI uses a password.
Researchers studied how the brain works when people try to speak or just think about speaking.
They used this information to teach the BCI to understand thoughts.
When the user thinks of a secret phrase (like a password), the device starts working.
This helps protect users' privacy and prevents the device from misinterpreting thoughts.
Scientists created a password-protected brain-computer interface (BCI).
The BCI translates brain signals into text or audio using internal speech.
Researchers analyzed brain signals in the motor cortex to develop the BCI.
Artificial intelligence models were trained to interpret imagined sentences.
A password, like 'Chitty-Chitty-Bang-Bang', activates the BCI, ensuring user control.
