A Study of Optimum Representation of Digital Contents on Smart Phones

Abstract

Currently, smart phones are widely used in the world. The way of display representation on digital contents is usually a combination of pictures, characters, voices and dynamic images. Since characters can communicate accurate information to people, the presentation of characters plays an important role in displaying information. As such, the research objective is to explore the optimum digital contents display for smart phones that can help users improve better viewing and operating. In this research, character contents of smart phones including (1) color matching of character and the corresponding background, (2) spacing between lines, (3) spacing between words, (4) character size, and (5) typeface are considered in the experimental design for analysis and evaluation. To conduct the study, the research divides the development procedure into three stages. They are (1) definition of experimental parameters and design of simulation display for building experimental environment, (2) implementation of experimental design for data collection, and (3) analysis of back-propagation neural network process for determining suitable character contents. The result showed that 12 to 16 pts for character size, line distance, and word distance will be preferred. In addition, DFKai-SB, PMingliU, Arial, and Times New Roman of Chinese and English typefaces are recommended. As to colors for character and background, a mixed black and white color is preferred. The research may need to make further investigation on the color issue. It is expected that the implementation of this research will provide designers with design references.
