Abstract
With the rapid development of interactive technologies using projection mapping (PJM), these digital technologies have introduced new interpretative possibilities for the presentation of cultural heritage sites. PJM attracts more visitors with greater expectations to cultural heritage sites through its excellent visual effects and guidance capabilities. In the past decade, especially after 2015, design events have frequently introduced digital projections to cultural heritage sightseeing spots worldwide. However, this trend has also led to the emergence of many digital projection events that merely exhibit beautiful projection effects on buildings and neglect to show the history and value of the cultural heritage site. Based on this phenomenon, this study compiled and analyzed 45 related cases of PJM applications at cultural heritage sites around the world from the past 5 years. These 45 examples were studied by disassembling the projection content, analyzing the information characteristics exhibited in each projection video, and arranging the obtained data on a timeline chart for analysis. According to the data, two information characteristics of PJM at cultural heritage sites can be observed: “the relationship between projection content and heritage” and “information tendency.” The advantages and limitations of these characteristics were distinguished and suggestions for the application of PJM on cultural heritage sites were derived. These results can be used as a reference for other research studies on visitors to cultural heritage sites and improving digital interpretation and presentation designs.
Highlights
With the rapid development of projection mapping (PJM) and interactive technologies, these digital technologies bring new interpretative possibilities for the presentation of cultural heritage sites through their excellent visual effects and guidance capabilities, which give visitors more motivation and expectations when visiting these tourism spots
Project organization and analysis Considering the large number of relevant PJM events in Japan and the fact that some events demonstrate traditional cultural elements related to the cultural heritage site of the event, this study mainly focuses on cases from Japan and presents analyses of more representative cases from around the world
Technology classification and analysis of PJM video contents Two questions were analyzed to clarify the relationship between PJM and cultural heritage at cultural heritage sites: “which techniques are applicable to cultural heritage sites?” and “which techniques can be used to represent the historical culture of the cultural heritage site?”[15]
Summary
With the rapid development of projection mapping (PJM) and interactive technologies, these digital technologies bring new interpretative possibilities for the presentation of cultural heritage sites through their excellent visual effects and guidance capabilities, which give visitors more motivation and expectations when visiting these tourism spots. Information about cultural heritage sites was previously conveyed through commentary panel discussions and models, which result in poorly updated information and viewing events that make it difficult to acquire information about the characteristics and histories of the cultural heritage sites [5]. PJM technologies can express a variety of information about the target cultural heritage site, which can be shared by multiple visitors [8]. PJM technologies have good interactive features with visual appeal that can enhance guided tours and information delivery [9]
