Abstract：Shadow Puppet，one of the national intangible cultural heritage, is phasing out of people's attention. To regain people's attention to the Shadow Puppet we designed the shadow puppet play system, which combines the modern computer technology with the traditional shadow puppet art. Using the high-performance embedded platform based on Intel(R) Atom(TM) processor, combine with self-designed digital control mechanical system, the system implemented features including recording the shadow puppet and shadow puppet automatically playing. For arranging and recording the shadow puppet，the system provides action edit player and drama edit player, and uses 2D physical engine，BPM detection algorithm and action coupling algorithm to improve the efficiency of shadow puppet editing . When the system controls shadow puppet robot play automatically，we uses spatial point to point maping algorithm to ensure the accuracy of system. The system also provides normal drama play mode and intelligent improvisation performance mode to make the system more entertaining and interesting. On the shadow puppet play stage the system uses high definition projector casts WPF background animation which makes play effect more outstanding. This system inherits and carries forward the Chinese traditional culture，it also provides people with a new audio-visual entertainment.

Abstract：Nowadays，information is becoming more and more important. People are constantly striving to find faster and convenient ways of recording important data and messages completely. Common digital recording tools，such as Digital Voice Recorder can only record voice, and those who uses handwriting pad may find it inconvenient to use a special pen to write. So we designed a new kind of handwriting pad called "Rubbing Tablet with the Synchronous Phonic Synthesization". Users can put a piece of paper over the pad，and use a common pen to write on it. Our pad will store the message in a digital way，and record the user's voice at the same. When he wants to review his notes，he will find three forms of message: notes on paper，digital data in hard disk and the words he spoke. Convenience is the main attraction of our pad，and that means more than simple portability. It will have high application value in education，industrial design，medical treatment and other areas in daily life.
