Cognitive display device

A computer program product comprising:

• a computer readable storage medium readable by one or more processors and storing instructions for execution by the one or more processors for performing a method comprising:
• obtaining, by the one or more processors, data indicating that a user of a visual display apparatus comprising an image capture device, and a projection device, communicatively coupled to the one or more processors, perceives displayed text with consistent character differences;
• obtaining, by one or more processors, from the image capture device, an image of the visual display within a visual range of the image capture device wherein the image comprises textual elements;
• based on the data, processing, by the one or more processors, the image to generate a new image, wherein the processing comprises transforming the image into the new image wherein the new image comprises the textual elements with pre-defined character substitutions based on the consistent character differences;
• and
• displaying, by the one or more processors, via the projection device, the new image, to the user, wherein based on viewing the new image, the user views the textual elements without the consistent character differences.

A visual display apparatus comprising:

• a memory;
• one or more processors in communication with the memory;
• an image capture device communicatively coupled to the one or more processors;
• a projection device communicatively coupled to the one or more processors;
• and
• program instructions executable by the one or more processors via the memory to perform a method, the method comprising:
• obtaining, by the one or more processors, data indicating that a user wearing the visual display apparatus perceives displayed text with consistent character differences;
• obtaining, by one or more processors, from the image capture device, an image of a visual display within a visual range of the image capture device wherein the image comprises textual elements;
• based on the data, processing, by the one or more processors, the image to generate a new image, wherein the processing comprises transforming the image into the new image wherein the new image comprises the textual elements with pre-defined character substitutions based on the consistent character differences;
• and
• displaying, by the one or more processors, via the projection device, the new image, to the user, wherein based on viewing the new image, the user views the textual elements without the consistent character differences.
