PlayMo is a publishing tool that allows publishing of interactive video, audio, and images, and easy creation of simulation models that have the same function as the actual object. Publishing electronics products, components, and educational contents through PlayMo allows the user to virtually manipulate objects on the Internet as if they were real. The contents can also be transformed into CD-ROM titles or MS-Office presentations. In addition, it is easy to create computer-based training (CBT) or online/offline education materials based on PlayMo models, and user manuals based on publishing models can be automatically created even for complicated products.
