Beyond virtual museums: Experiencing immersive virtual reality in real museums     

Marcello Carrozzino  Massimo Bergamasco   《Journal of Cultural Heritage》2010,11(4):313-458

Contemporary museums are much more than places devoted to the placement and the exhibition of collections and artworks; indeed, they are nowadays considered as a privileged means for communication and play a central role in making culture accessible to the mass audience. One of the keys to approach the general public is the use of new technologies and novel interaction paradigms. These means, which bring with them an undeniable appeal, allow curators to modulate the cultural proposal by structuring different courses for different user profiles. Immersive Virtual reality (VR) is probably one of the most appealing and potentially effective technologies to serve this purpose; nevertheless, it is still quite uncommon to find immersive installations in museums. Starting from our 10 years’ experience in this topic, and following an in-depth survey about these technologies and their use in cultural contexts, we propose a classification of VR installations, specifically oriented to cultural heritage applications, based on their features in terms of interaction and immersion. On the basis of this classification, aiming to provide a tool for framing VR systems which would hopefully suggest indications related to costs, usability and quality of the sensorial experience, we analyze a series of live examples of which we point out strengths and weak points. We then summarize the current state and the very next future, identifying the major issues that prevent these technologies from being actually widespread, and outline proposals for a more pervasive and effective use of Immersive VR for cultural purposes.  相似文献

Researching Internet Communities: Proposed Ethical Guidelines for the Reporting of Results   总被引：4，自引：0，他引：4  

Storm A. King 《The Information Society》1996,12(2):119-128

Communication researchers and social scientists are quickly discovering the value of data that exists in the postings of members of Internet e-mail, Usenet, and real-time groups. The ability to communicate with one's peers, no matter how esoteric the interests, is causing an explosion in the number of new virtual communities. The interpersonal dynamics of these groups are increasingly coming under the scrutiny of academic research. The publicly available archived records of Internet virtual communities are being analyzed for a wide variety of research interests. The ability to do naturalistic observations of group dynamics, as they are exhibited in these exchanges of text, has captured the attention of many researchers. The institutional review boards of major universities are granting researchers exempt or expedited (exempt from full review) status for this work, due to the public nature of the notes being analyzed. These studies often involve the lack of informed consent, where the group members under study are unaware they are being monitored. There is a potential for psychological harm to the members of these groups, depending on the way results are reported. This article explores the ethical considerations that must be taken into account to protect cyberspace participants. The guidelines proposed are based on the American Psychological Association ethical guidelines for use of human subjects in research. An explanation is offered as to how such guidelines can best be applied to the study of Internet communities. The constructs of Group Accessibility (the public/private nature of the actual cyberspace occupied by a group) and Perceived Privacy (the level of privacy that group members assume they have) are defined and proposed as two dimensions by which individual Internet communities may be evaluated in order to assure the ethical reporting of research findings.  相似文献

紫外光谱法研究久效磷与碱基的相互作用     

王丽  刘飞  桑宏庆 《安徽科技学院学报》2014,(5)

为利用组合化学原理构建核酸适体库,确定久效磷适体筛选缓冲体系的最适 pH 值及离子强度,采用紫外吸收光谱法研究了不同 pH 值及不同 Na ﹢、K ﹢和 Mg2﹢浓度的缓冲溶液中久效磷与四种碱基的相互作用。结果表明,pH 值及 Na ﹢、K ﹢和 Mg2﹢浓度对久效磷与四种碱基的作用有明显的影响,pH7.6、Na ﹢浓度200 mmol/ L、K ﹢浓度40 mmol/ L、Mg2﹢浓度15 mmol/ L 的50 mmol/ L Tris 缓冲溶液中久效磷与四种碱基的作用相对较强,可以作为久效磷适体筛选的参考缓冲体系。在此缓冲体系下,久效磷与四种碱基作用的强弱依次为胞嘧啶、胸腺嘧啶、腺嘌呤、鸟嘌呤。因此,构建核酸适体库时可以适当增加胞嘧啶、胸腺嘧啶的比例。  相似文献
