Abstract: A process for ocular analysis is disclosed. Aspects of the process display, on a device having a display and a camera sensor, a regimented pattern as a stimulus. The camera sensor captures video of an environment. The process also involves isolating an iris within the environment as a bounded region of the captured video. Facial landmarks are assigned to the iris within the bounded region. Thereafter, raw movement data of the facial landmark in response to the regimented pattern is extracted from the captured video. The raw movement data is used to create filtered movement data (e.g., data that has been checked for errors). The process also compares the filtered movement data to a predetermined movement response that is based on the regimented pattern. From the comparison, a performance score is generated. The performance score is used to generate an output.
