数字显示器是公共空间的一个普遍特征。伦敦最近在其地铁站部署了一整套新显示屏网络,纽约时代广场的屏幕可以展示超过 16,000 平方英尺的数字媒体。然而,尽管对普适显示进行了数十年的研究,但调度内容的问题仍未得到解决,并且在解决大规模和开放显示网络带来的挑战方面几乎没有前进的动力。本文提出了第一个用于在当前和预期的普及显示系统中进行调度的综合架构模型。与之前的工作相比,我们的三阶段模型将高级目标设定的过程与内容过滤和选择分开。我们的架构的动机是对文献的广泛回顾和对需求的详细考虑。该架构是通过旨在服务于世界上最大且运行时间最长的普适显示器研究测试平台的实现来实现的。混合方法评估从三个角度确认了该架构的可行性:展示满足明确要求的能力、完全满足典型显示部署需求的性能,以及证明其能够充当前述研究测试台的日常调度平台的能力。根据我们的评估和对整个论文的反思,我们确定了将影响普遍显示调度未来研究和开发的十大影响。
Digital displays are a ubiquitous feature of public spaces; London recently deployed a whole network of new displays in its Underground stations, and the screens on One Time Square (New York) allow for presentation of over 16,000 square feet of digital media. However, despite decades of research into pervasive displays, the problem of scheduling content is under-served and there is little forward momentum in addressing the challenges brought with large-scale and open display networks. This paper presents the first comprehensive architectural model for scheduling in current and anticipated pervasive display systems. In contrast to prior work, our three-stage model separates out the process of high level goal setting from content filtering and selection. Our architecture is motivated by an extensive review of the literature and a detailed consideration of requirements. The architecture is realised with an implementation designed to serve the world's largest and longest-running research testbed of pervasive displays. A mixed-methods evaluation confirms the viability of the architecture from three angles: demonstrating capability to meet the articulated requirements, performance that comfortably fits within the demands of typical display deployments, and evidence of its ability to serve as the day-to-day scheduling platform for the previously described research testbed. Based on our evaluation and a reflection on paper as a whole, we identify ten implications that will shape future research and development in pervasive display scheduling.
