Abstract-the purpose of our paper is to explore the structure of DIY products with colors on the surfaces of part in a graphical manual drawn by computer tool. In additions, we want to find up a good representation of a manual for the DIY users to better understand and easy to assemble a product. Many manuals of DIY merchandises are owing to ambiguous graphics, the buyers take much time to assemble parts together correctly during the process of work. Our research designs one empirical study to evaluate the effectiveness and visual comprehension about the graphical expression of the manual of product. After the experiment, we analyze these data through statistic techniques of ANOVA dan CHI Square. Our experimental results show that there will be good perceptibility to understand the process and positions of assembly works when they have colors and apply other design elements on the manuals. The validation of empirical information could be translated into other products that need to be expressed by computer graphics in manuals. Keywords-DIY ; Features ; Assembly ; Manuals.
