在分析Google桌面搜索工具(GDS)运行机制的基础上,提出一种基于GDS开发站内全文搜索引擎的方法：开发一个专用的Web代理GDSProxy,采用接受与转发机制支持用户对GDS搜索服务的远程访问,转发过程中增加用户IP地址限定、身份认证、日志处理和信息过滤等功能,站内信息的挖掘、索引和本地搜索服务由GDS承担。最后,通过开发实例介绍具体实现步骤。 相似文献

提出了一种基于桌面云的高校实验室多媒体设备管理系统。桌面云平台是一种以C/S为中心的体系结构,其主要目的在于能够为多种虚拟化工具提供一个稳定、便捷的网络环境。通过对用户的资源访问行为进行限制和管理,来阻止非法用户的未经授权访问和合法用户的跨权限访问。通过对桌面数据进行拦截,可以实现与客户机之间的软件和硬件的无缝连接。经过多次试验,验证了该方案的可行性。 相似文献

Abstract Primo Analytics from two campuses of the California State University system has revealed that a dramatically low proportion of Primo searches originate from mobile devices. The current study focuses on usability concerns as one area that may be preventing students from searching the Primo mobile interface. The sample for this study includes students from two campuses with a variety of experience with library instruction and searching the library’s discovery system. Participants were given the same set of six common academic tasks to complete. Both mobile and desktop participants found three tasks relatively easy to complete. When there were differences in completion rates between the mobile and desktop users, the desktop users were overall more successful. No task was consistently difficult for desktop users to complete, while mobile users found two of the tasks very challenging to complete. Based on the findings, the authors make recommendations for improving the experience of mobile users. 相似文献

Changes presented by cloud computing—shared computing services, applications, and storage available to end users via the Internet—have the potential to seriously alter how libraries provide services, not only remotely, but also within the physical library, specifically concerning challenges facing the typical desktop computing experience. Libraries have invested time and money in establishing an infrastructure to support a particular kind of computing experience, and advances in cloud computing may make this type of experience obsolete. One of the ways libraries have added value to their services has been by implementing library commons. A key component to these commons has been desktop computing. Cloud computing offers applications via a Web browser, meaning that the applications can run independently of the local hardware and operating system, calling into question the necessity of traditional desktop computing. As libraries have shown in the past, they have the capability to assess challenging situations and adapt to provide users a beneficial experience. 相似文献

This study examines whether the naturalness of a device’s perceptual system, which defines the way users look around in the virtual environment, influences the persuasive effects of immersive virtual reality (IVR) advertising. In a between-subject experiment (N = 115), participants watched a 360-degree advertisement using one of three devices with different perceptual systems (a head-mounted display [HMD], a tablet, or a desktop computer, representing high, medium, and low naturalness respectively). The results revealed that participants who watched IVR advertising using a more naturally mapped perceptual interface (i.e., an HMD) reported higher levels of perceived naturalness than did those who used devices lower in naturalness (i.e., a tablet or a desktop computer). The use of a perceptual system with a higher level of natural mapping positively affected the sense of presence, which in turn enhanced advertising enjoyment and further improved the effects of IVR advertising, thereby yielding a three-step serial mediation model. 相似文献

ABSTRACT This article describes the investigation, pilot test, and results of implementing electronic document delivery in a paperless processing environment at The Ohio State University. The Prior Health Sciences Library Document Delivery Unit conducted a twelve-month pilot test from September 1999 to August 2000 to determine the best method for desktop document delivery and the paperless processing of requests. Participants completed a survey and provided insightful feedback on the request form and overall process. Special programming was required to implement desktop delivery and manage client requests. The result of desktop delivery was successful. The results of paperless processing were mixed. Future possibilities to complete the “paperless” environment are suggested. 相似文献

This article describes an online system to collect, store, analyze, and report reference statistics. Information is entered at the point of service in a Web-based interface located on the computer desktop of each librarian. When record keeping and reporting processes were customized, automated, and made accessible to librarians, the data collected proved invaluable in tracking trends in reference service, monitoring library initiatives, and providing reference librarians information for analyzing and assessing their professional activity. 相似文献
