The Internet has spurred the popularity of online or virtual museums that preserve historical heritages and promote traditional cultures. However, the contents of existing online museums are often too professional for ordinary visitors to understand. This situation dampens visitor interest toward historical cultures or heritages, especially such history beginners who often lack sufficient background knowledge. In this paper, we designed and developed a prototype system for online museums for beginners based on an investigation of existing online museums and the cognitivism of learning and social constructivism theories. Our proposed system has several points that are different from existing online museums: (1) it illustrates artworks with multidimensional information; (2) it integrates correlative information around artworks; (3) it locates artworks on Google Maps based on their geographic information. Our online museum offers great help for history beginners and will facilitate a deeper understanding of history.
