The point reading pen needs to be used in conjunction with the picture book. The dictionary pen can scan any books and teaching materials, and both Chinese and English can be recognized, which is equivalent to putting the dictionary in the pen. At the same time, it can also make a comprehensive pronunciation annotation for single words, as well as English-Chinese translation and Ying Ying translation. If the baby is less than 2-3 years old, point reading pen is recommended, and dictionary pen is recommended for 3- 16 years old. I chose an alpha egg dictionary pen for my child, which can not only scan Chinese and English, but also scan and read classical Chinese poetry, with explanations and allusions. He likes it very much.
