BCI and Evaluation of Visual and Task Performance in Subjects With Eye Diseases

Participants came to the clinic in person for 2 hours for visual performance tests once every 6 months for up to 5 years. These tests included virtual reality tests and tests on a computer screen to investigate performance during simulated daily life activities, such as driving, situations of low contrast and glare.

The brain-computer interface (BCI) consists of a modified virtual reality goggle integrated with wireless no-prep electroencephalogram (EEG). The portable BCI is able to objectively measure multifocal steadystate visual evoked potentials in response to brain stimulation through presentation of visual stimuli in the goggle. The test is done in person and may take up to 30 minutes, once every 6 months for up to 5 years.
