碩士 === 國立臺北科技大學 === 工業工程與管理系碩士班 === 101 === With the evolution of projection technology, micro-projectors have been rapid developed. Its applications range from conventional stand-alone sets to embedment in portable devices. However most of the research on micro projection technology has mainly been related to the applications with mobile phones but not to the design of user interfaces or user experience. Therefore, this study aims to understand whether content types and projection distances have significant impacts on user subjective preferences. There were three contents types and six projection distances as the independent variables, participants’ responses on their preferences as the dependent variable. A repeated-measures ANOVA was used to analyze the date. A brief question was also asked after the experiment to understand participants’ rationale behind their responses. Results showed that significant effects on user preferences were found from the different projection distances and from the interactions between the projection distances and the content types, but not from the different content types. Projection distance in one meter had the highest preference, due to its screen size and the level of brightness. For the interaction effects, user preferred static pictures to dynamic video in one-meter projection distance. However, this preference was reversed in the distance of two meters. Results of the question after the experiment have confirmed that the sizes and levels of brightness primary factors to influence user preferences. It is believed that the findings of this study will help industry to better understand the needs of users, so that it can better meet the technology development and application market demand.
