Abstract
Eyewear for capturing and processing electroencephalogram (EEG) signals. The eyewear includes one or more biopotential measurement systems attached to rearward extensions of the temple arms of the eyewear. The biopotential measurement systems include an electrode arrangement that contacts the scalp of a user of the eyewear for capturing EEG signals of the user. The eyewear further includes a reference electrode mounted on a frame of the eyewear and in contact with the nose of the user. The eyewear processes the EEG signals to provide user inputs into software applications.
Claims21
An electroencephalogram (EEG) device comprising:
- a frame;
- a first temple arm connected to a first side of the frame, and a second temple arm connected to a second side of the frame opposite the first side of the frame;
- a reference electrode placed above one ear of a user within an inner portion of the first temple arm;
- and
- a bias electrode placed above another ear of the user within an inner portion of the second temple arm;
- and
- a biopotential measurement system comprising one or more electrodes, the biopotential measurement system mounted on a rearward extension of at least one of the first temple arm and the second temple arm, the biopotential measurement system positioned proximate to an occipito-temporal cortex of a wearer's brain, the reference electrode and the bias electrode each separated from the one or more electrodes of the biopotential measurement system.
