Augmenting the Periphery with Large-Scale Visual Displays

这项研究的目的是探索和评估在人机界面中添加视觉外围显示的可能性。通过一系列实验室实验，结合可用性评估和系统原型的实地试验，PI将深入探索如何在办公室环境中有效利用外围信息。PI和她的团队将设计和构建一个界面，使用投影视觉显示将用户的虚拟工作空间扩展到他/她的桌面显示器的限制之外，然后使用它以支持当前工作实践的方式增强办公室环境。强调支持当前的工作实践，以及由此导致的台式计算机的纳入，与未来世界的愿景形成了鲜明对比，在未来世界，台式计算机要么被过多的计算设备(无处不在的计算)取代，要么被单一的个人头戴式显示器取代，后者将信息叠加在佩戴者的世界观上(可穿戴式增强现实)。PI认为，她的方法，加上一系列精心设计的实验室实验，将导致对在现实环境中部署外围显示器所涉及的问题的深入理解。这项研究预计将有几个重要的结果。它将导致确定和模拟用户的工作环境的技术，特别是对这些环境中的文件进行排序和分类；这些技术将使用户能够在任务之间轻松切换，快速恢复先前工作的最后状态，并保持对过去使用的文件的认识。这项研究还将带来视觉呈现外围信息的技术，可能是视觉蒙太奇，旨在通过传达一条信息的显著部分，包括其周围环境，同时保持低调，利用外围感知机制。最后，研究将为3D外围空间的设计提供洞察力，该空间增加了传统桌面终端的使用，重点是根据材料的相关性和熟悉度将该空间划分为逻辑组，以及随着材料变得与当前任务或多或少地相关，空间的动态行为。

The goal of this research is to explore and evaluate the addition of visual peripheral displays to human-computer interfaces. Through a series of laboratory experiments, in conjunction with usability evaluations and field trials of system prototypes, the PI will conduct an in-depth exploration of how peripheral information can be used effectively in an office setting. The PI and her team will design and build an interface that uses projected visual displays to extend the user's virtual workspace past the confines of his/her desktop monitor, and then use it to augment an office environment in a way that supports current working practices. The emphasis on supporting current work practice, with its resulting inclusion of desktop computers, is in sharp contrast to visions of tomorrow's world where the desktop computer is replaced by either a plethora of computing devices (ubiquitous computing) or a single personal head-worn display that superimposes information over the wearer's view of the world (wearable augmented reality). The PI posits that her approach, coupled with a set of carefully designed laboratory experiments, will lead to a deep understanding of the issues involved in deploying peripheral displays in realistic environments. This research is expected to have several important outcomes. It will lead to techniques for determining and modeling a user's working contexts, especially the ranking and clustering of documents within those contexts; these will enable the user to easily shift between tasks, quickly regaining the last state of previous efforts and maintaining an awareness of documents used in the past. This research will also lead to techniques for visually presenting peripheral information, perhaps as visual montages designed to take advantage of peripheral perception mechanisms by conveying the salient portions of a piece of information, including its surrounding context, while remaining unobtrusive. Finally, the research will provide insight into the design of a 3D peripheral space that augments the use of traditional desktop terminals, with emphasis on the division of this space into logical groups based on the relevance and familiarity of the material, and the dynamic behavior of the space as material becomes more or less relevant to the current task.
