An optical learning machine has an optical reader on the bottom end as an input device to read an index code in instructions. The index code is printed in the instructions in a planar manner. A microprocessor located in the machine retrieves an instruction file from a memory card interface in a memory device corresponding to the index code and transforms to sound or images that are sent to audio and image display devices. Hence symbols may be transformed through the optical reader to instruction contents of a multimedia format to be output to achieve an interactive effect.
