As a study abroad student in Japan I was encouraged to buy an electric dictionary that came with a stylus. You write the character you see and it gives the definition. (unfortunately these are designed for Japanese people so it doesn't get the character if you write it with the wrong stroke order, and it brings you to a page of japanese text explaining all about the character and its uses in different contexts, but still, pretty useful)
