This invention is directed to a bio-potential electrode-set for measuring electrical signals during an electrooculogram (EOG) from a human, particularly to flexible self-adhesive bio-potential sensing electrode-set substrate specifically to cover the perimeter of the eyes for EOG recordings. In general, EOG is a technique for measuring the cornea-retinal standing potential that exists between the front and the back of the human eye. The resulting signal is called the electrooculogram. Primary applications include, but are not limited to, ophthalmological assessments that require recording eye movements or gaze tracking and human computer/machine interfaces.

In some embodiments, a display system comprising a head-mountable, augmented reality display is configured to perform a neurological analysis and to provide a perception aid based on an environmental trigger associated with the neurological condition. Performing the neurological analysis may include determining a reaction to a stimulus by receiving data from the one or more inwardly-directed sensors; and identifying a neurological condition associated with the reaction. In some embodiments, the perception aid may include a reminder, an alert, or virtual content that changes a property, e.g. a color, of a real object. The augmented reality display may be configured to display virtual content by outputting light with variable wavefront divergence, and to provide an accommodation-vergence mismatch of less than 0.5 diopters, including less than 0.25 diopters.

A sleep-monitoring cap includes interconnected electrodes embedded within a body of the sleep-monitoring cap. The interconnected electrodes are located at positions across a central transverse region, below and along a side of each eye, and on a rear mid-region of a person's head when wearing the sleep-monitoring cap. The sleep-monitoring cap includes a vibratory device embedded within the sleep-monitoring cap, wherein the vibratory device is connected to the interconnected electrodes. The sleep-monitoring cap includes processing circuitry embedded within the sleep-monitoring cap. The processing circuitry is configured to monitor, convert, process, and store brain wave activity retrieved by the interconnected electrodes from the person wearing the sleep-monitoring cap; determine whether the monitored brain wave activity includes low amplitude mixed-frequency waves and if so, activate the vibratory device; determine whether the monitored brain wave activity includes theta waves followed by vertex sharp waves and if so, activate the vibratory device.
