Keep in mind that I’m not a teacher, however, from previous experience with people with what we assume are disabilities, talk to the student. Would the student even favor blueprints over writing c++? How does the student visualize / understand the environment?
People learn in many different ways. If you know that the student will be in the class, schedule a meet and greet and try to understand what he wants to take away from the course, and then modify it to suit his/her learning style and abilities.
Screen readers and programs such as Dragon / Voice attack are bloody amazing as far as the speech interaction with computer base environments, so as long as you or a TA helps him/her set it up, they should be good to go.
