Data presented in a visual image is monitored and verified. A processing component receives data from sensors and other sources, and interprets the data to generate processed data. A render component generates a visual image based on the processed data. A projector component projects the image, which is received by a splitter component that splits the light stream of the image and routes a portion of light energy to the display screen viewed by the user and another portion of the light energy to a data verification component (DVC). DVC interprets information presented in the image to determine the data being presented to the user by the image. DVC also receives the processed data from the processing component. DVC compares the data determined from the image to the processed data to determine whether they match and takes appropriate responsive action if they do not match.
