Human-Computer Interaction in Spatial Augmented Reality

我们正处于下一个计算模式的黎明，我们周围的一切都将用数字信息来增强。与只能通过手机或特殊眼镜查看的增强现实不同，多个投影仪-相机单元将在任意对象和表面上放置可寻址的像素，以创建空间增强现实(SAR)。这将意味着我们获取数字信息的方式发生革命性的变化。例如：手术前可视化的无菌和整洁方式；智能家居和物联网的无处不在的显示方法；办公室和设计工作室中显示空间的更灵活和可访问的使用；以及人力制造和维护方面的培训和定制的新可能性。公司现在正在开发合成孔径雷达显示技术，但显示信息只是解决方案的一部分。人机交互(HCI)研究有一个基本的悬而未决的问题：“人的输入应该如何整合到SAR中？” 候选人已经获得了180万美元的资金，用于在非沉浸式、交互式的SAR(我们称为完全交互式物理数字空间，简称FIPS)中进行人机交互研究。拟议的研究计划支持HQP使用这一最先进的设施来专门探索远距离执行时的SAR输入和交互。这两个目标是：提供表征和模拟远程输入的经验结果；发明实用、可用、舒适和有效的远程交互技术。这些目标将作为三项工作流进行，每项工作都侧重于一种投入背景。Stream 1专注于基于设备的输入，并探索使用智能手表来操作SAR中的内容(作为一种当前实用的技术)，以及发明一种全新的手持设备，其灵感来自考生的接触感应器Conté。流2的重点是基于手的输入，它研究了在合成孔径雷达中使用徒手交互时的关键研究问题：模式切换、视觉反馈和基于手的交互的最佳风格。流3研究了隐含的全身姿势(如坐或站)和显性的身体动作(如脚部轻拍)如何增强和改进流1和流2中的技术。最后，一个顶峰主题将所有结果联系在一起，在一个示范的SAR演示应用程序中，并将结果编码到一个HCI SAR开发工具包中。 拟议的研究计划将通过在尖端技术设施中发明人机界面的未来，在核心人机界面研究技能方面培训4名博士、3名硕士和多名本科生。拟议的研究结果将使人们更好地了解基于人类需求和能力的SAR交互的潜力，并最终发明新的交互技术和方法，以引领商业应用。

We are at the dawn of the next computing paradigm, where everything around us will be augmented with digital information. Instead of an augmented reality viewable only through a phone or special glasses, multiple projector-camera units will place addressable pixels on arbitrary objects and surfaces to create a Spatial Augmented Reality (SAR). This will mean a revolutionary change in how we access digital information. For example: a sterile and clutter-free way for surgical pre-visualizations to be accessed during an operation; a ubiquitous display method for smart homes and the internet of things; a more flexible and accessible use of display space in offices and design studios; and new possibilities for training and customization in human-powered manufacturing and maintenance. Companies are developing SAR display technologies now, but displaying information is only part of the solution. There is a fundamental open question for Human-Computer Interaction (HCI) research: “How should human input be integrated into SAR?” The candidate has already secured funds to build a $1.8 million facility to conduct HCI research in non-immersive, interactive SAR (which we call Fully Interactive Physio-digital Spaces, or “FIPS”). The proposed research program supports HQP to use this state-of-the-art facility to specifically explore SAR input and interaction when performed at a distance. The two objectives are: contribute empirical results which characterise and model distant input; and invent distant interaction techniques that are practical, usable, comfortable, and efficient. These objectives will be pursued as three streams of work, each focused on one input context. Stream 1 focuses on device-based input, and explores using a smartwatch to manipulate content in SAR (as a technology that is currently practical), as well as inventing a totally new type of hand-held device inspired by the candidate's contact-sensing “Conté”. The focus of stream 2 is hand-based input, which investigates key research problems when using bare hands to interact in SAR: mode-switching, visual feedback, and the best style of hand-based interaction. Stream 3 looks at how implicit whole-body poses (like sitting or standing) and explicit body movements (like foot taps) can augment and refine techniques from streams 1 and 2. Finally, a capstone topic ties all results together in an exemplar SAR demonstration application and encodes findings in a HCI SAR development toolkit. The proposed research program will train 4 PhD, 3 Master's, and multiple undergraduates in core HCI research skills by inventing the future of HCI in a cutting-edge technology facility. The results of the proposed research will be a greater understanding for the potential of SAR interaction based on human needs and capabilities, and ultimately, the invention of new interaction techniques and methods to lead the way towards commercial applications.
