Abstract
An electrocorticography-based brain computer interface (BCI) and related methods are described.
Claims13
A brain computer interface (BCI) comprising:
- an electrocorticography (ECoG) electrode array adapted to be implanted beneath the scalp of a user and configured for acquiring electrocorticography (ECoG) signals of the subject;
- an acquisition computer coupled to the electrode array for collecting and storing the ECoG signals;
- and,
- coupled to the acquisition computer, a BCI computer having software configured to analyze the ECoG signals to determine an intent of the user.

A brain computer interface BCI comprising acquisition hardware for acquiring an ECoG signal communicatively coupled to a BCI computer configured to analyze the ECoG signal to determine an intent of a user.
A method for providing control of an output device by a user comprising:
- collecting ECoG signals of the user's brain activity using an electrocorticography (ECoG) based brain computer interface (BCI);
- and
- computer processing the ECoG signals to determine an intent of the user with respect to the output device.
A method of controlling movement of a cursor on a computer monitor in real time comprising:
- monitoring electrocorticography (ECoG) signals of the brain activity of a subject;
- analyzing the ECoG signals to determine the intent of the user with respect to the cursor movement;
- comparing the intent of the user to a current position of the cursor;
- generating from the intent of the user a device command to the computer monitor to move the cursor;
- providing feedback to the user on the current position of the cursor;
- reanalyzing the ECoG signal to determine an intended correction by the user with respect to the cursor movement;
- communicating the intended correction by the user to the computer monitor to modify movement of the cursor.
