Kanji Reader. A litlle device with a bilingual interface, a high precision optical scanner able to digitize kanji and other Japanese characters( around 3000). It seems that it can do both E-J and J-E.
It is not that expensive and I think it is very handy considering that it is the size of a pen. Personally, I still need to learn the "analog" way and then I would like to have a device like this to help me when I need it.
