Introducing “Touch and Talk Pen”
One of our classmates at Tsinghua University has invented “Touch and Talk Pen” (TTPen), and produced a series of educational materials (for learning Chinese and English). The TTPen incorporated an optical sensor which can recognize the characters and text in the books, and can speak the word, sing songs and engage children for an interactive play, just with the TTPen and TTPen-enabled books (which has special pattern dots in the background of pages).
The TTPen has been a huge success in China and is being used widely in school. For the first time we have make the TTPen and books available in North American. You may check out at our website:
