The softwares functionality is rather disappointing when trying it on real stuff like mangas. Character OCR for Kanji should be possible and I really hope that lucsens is able to produce something that is able to match the levels that Pleco (a Chinese dictionary) is capable of. Therefore I know it is possible to do better than this.
Currently I consider Japan Goggles Beta Quality Software and hope that they are able to improve it.
