This study addresses the learning of the elements in energy saving and CO2 reduction education and their relevant properties by using augmented learning based on character design.This study uses technologies that include character design,interactive game cards,augmented reality technology,and interactive multimedia design to create “Kung Fu Chemistry Family” game.This game is designed to make learners learn the formulae of H2O,CO2 and H2CO3.This study uses the properties of the three chemical elements to design 2D/3D characters to make learning more fun and meet the goal of "learning by playing”,as serious games.Every chemical element in the game has been personalized to fulfill a different role in the family,and each elements character corresponds to its properties as a chemical element.A prototype of a multimodal digital learning serious game to chemistry elements had been developed.Forty elementary students participated in the assessment of the designed materials.The results show that the extent to which users are engaged in innovative interaction digital learning,determines the success rate.However,learning can be affected when information displayed on the screen is not significant enough.The user experiences and a usability test will necessitate a follow-up study.
