Quick Response Code (QR Code) has already developed in the Asian and other region. In recent years cellular phone telecommunication in Taiwan to set up this function and can be built into the download function on their own mobile phones. There will be more innovation and breakthroughs for act barcode utilization in the future. A tactic for small-scale exhibition increases gradually because of crowded Taiwan. On the considerations of exhibition planning and the cost,whether the small-volume with high- capacity storage QR Code becoming the assistance for is the navigation aids , and the public to get information of exhibition is the main motivations for the research. The purpose of this research is: (1) To understand the characteristics and development of the current bar code operation.(2) To induce the cases and strategies of current QR Code applied to exhibition.(3) To collect acceptance of audience guided in exhibition assisting by QR Code.(4) To discuss the learning effects of the public through assistance of QR Code in exhibition. In accordance with the purposes of this research, using interviews with experts and explore the literature,summarized the characteristics suitable for use in exhibition. Through questionnaire survey and observing methods,Set up a experimental exhibition site by assistance of QR Code.The experiment results reveal that from the learning effects through the guide of QR Code, the T examination result has reached the significant level (P<0.05).The data presents that QR Code after the guide of there are significant differences in learning effect the guide of QR Code provides the promotion for exhibition content meaning that of learning. In this study, we want to know the characteristics of QR Code applied to convey information of the navigation aids.To provide the combination of exhibition and QR Code in the future, whether it is applied to the navigation system or application of exhibits showing.
