Abstract
A duration of time in which an individual observed a region can be determined. An image can be received. The image can include an indication of a point of gaze of the individual at a production time of the image. The image can include a visual fiducial marker, which can be disposed at a position in the image and can include a visual symbol. The visual symbol can be associated with data that define the region. The region can have a shape and a size and can be disposed a displacement in a direction from a position of the visual fiducial marker. Using the visual symbol, a location of an edge of the region can be determined. The indication of the point of gaze can be determined to be within the region. The production time of the image can be determined to be within the duration of time.
