About this trial
The investigators will evaluate a computer-animated character that explains medical illustrations to people, comparing the character to having people understand the illustrations on their own, and also comparing the computer character on a computer display to one in immersive virtual reality. The investigators will determine which method leads to the best understanding and lowest anxiety.
