Interaction with three-dimensional (3D), spatial data is increasingly common. Spatial data are important for many sectors, including interior design, architecture, urban planning, industrial planning and design, simulation, training, animation, the game and entertainment industry, and the new “maker” movement. Yet, user interfaces for spatial data are complex, difficult to learn, or limited in functionality. My research program investigates better spatial user interfaces for 3D content. The new spatial hybrid user interfaces are a combination of user interfaces, where the user manipulates virtual objects quickly in the air, with the best of desktop user interfaces. Working towards the vision of spatial user interfaces that are efficient as 2D interfaces, the research program involves three main thrusts: characterization of basic operations, accurate interaction, and new technologies. The first thrust investigates how well current, basic spatial interaction techniques, such as 3D rotations, docking, and travel, perform in terms of speed and accuracy. Moreover, the research also investigates how fast transitions between in-air and desktop interfaces are and how reliable gestures are as a substitute for buttons and keys. While in-air manipulation seems attractive, the available experimental data points to a lack of precision. Thus, we investigate hybrid combinations of in-air and desktop interfaces in the second thrust, where the desktop interface is used for fine-tuning of the final result. Such combinations will yield hybrid spatial user interfaces for 3D content creation and editing that are both fast and precise. Moreover, we study new techniques for resolving depth ambiguities and switching between mono- and stereoscopic viewing. The final thrust of this research program investigates new tracking technologies for fingers and pens, with the aim to further increase tracking accuracy. The fundamental contributions of my research program will be accurate quantifications of the throughput of existing and new spatial interaction techniques, new methodologies for evaluation of interaction methods, novel design guidelines, as well as new technologies. Together, the work constitutes a major step forward towards high-performance spatial user interfaces that are still easy to learn. Better spatial user interfaces will increase the accessibility of 3D modeling for non-specialists, which in turn will accelerate the adoption of 3D content manipulation and creation by the general public, e.g., driven by the new maker/3D printing movement. Moreover, 3D content creation and gaming are core Canadian strengths. Canada will benefit from the research program presented here through many globally competitive HQP in user interface design and 3D graphics, as well as a potential startup. Also, the broad applicability of the results will increase interest in science and technical disciplines.

与三维 (3D) 空间数据的交互越来越普遍。空间数据对于许多领域都很重要，包括室内设计、建筑、城市规划、工业规划和设计、模拟、培训、动画、游戏和娱乐行业以及新的“创客”运动。然而，空间数据的用户界面复杂、难以学习或功能有限。我的研究项目研究更好的 3D 内容空间用户界面。 新的空间混合用户界面是用户界面的组合，用户可以在空中快速操纵虚拟对象，并具有最好的桌面用户界面。该研究项目致力于实现与 2D 界面一样高效的空间用户界面的愿景，涉及三个主要重点：基本操作的表征、准确的交互和新技术。 第一个重点研究当前的基本空间交互技术（例如 3D 旋转、对接和旅行）在速度和准确性方面的表现。此外，该研究还调查了空中界面和桌面界面之间的转换速度以及手势替代按钮和按键的可靠性。虽然空中操纵似乎很有吸引力，但现有的实验数据表明缺乏精度。因此，我们在第二个推力中研究了空中和桌面界面的混合组合，其中桌面界面用于对最终结果进行微调。这种组合将产生混合空间用户界面，用于快速而精确的 3D 内容创建和编辑。此外，我们研究了解决深度模糊性以及在单视场和立体观看之间切换的新技术。该研究计划的最终目标是研究手指和笔的新跟踪技术，旨在进一步提高跟踪准确性。 我的研究计划的基本贡献将是对现有和新的空间交互技术的吞吐量的准确量化、交互方法评估的新方法、新颖的设计指南以及新技术。总之，这项工作构成了向易于学习的高性能空间用户界面迈出的重要一步。 更好的空间用户界面将增加非专业人士对 3D 建模的可及性，这反过来又将加速公众对 3D 内容操作和创建的采用，例如在新创客/3D 打印运动的推动下。此外，3D 内容创作和游戏是加拿大的核心优势。加拿大将通过许多在用户界面设计和 3D 图形方面具有全球竞争力的 HQP 以及潜在的初创公司从这里提出的研究计划中受益。此外，研究结果的广泛适用性将增加人们对科学和技术学科的兴趣。
