Interacting with complex information spaces integrated with physical reality on mobile devices

飞机机械师和航空航天制造和维护中的其他利益相关者进行的知识工作提出了许多技术和人力挑战。他们反复绘制以多种格式呈现的复杂技术信息之间的相关性（例如，纸质工程原理图、零件数据库、2D/3D模型），并将这些数据与飞机本身关联起来。他们的工作是由程序，精心设计，测试，并在持续的基础上进行管理，往往导致从一个飞机模型到下一个截然不同的程序框架。飞机机械师需要访问复杂的3D模型，并支持各种设备形状因素（例如，大型触摸屏、平板电脑屏幕、智能手机）的数字数据，并且需要在工作期间在这些异构平台之间流畅地移动。将数字数据整合到机制的工作流程中需要全新形式的针对性、情境相关的信息可视化和交互。最后，为了在飞机环境中定位复杂的数字信息，需要无处不在的传感基础设施。

The knowledge work conducted by aircraft mechanics and other stakeholders in aerospace manufacturing and maintenance poses many technical and human challenges. They repeatedly draw correlations across complex technical information presented in multiple formats (e.g., paper engineering schematics, parts databases, 2D/3D models), and correlate that data with the aircraft itself. Their work is governed by procedures that are carefully designed, tested, and managed on an ongoing basis, often leading to vastly different procedural frameworks from one model of aircraft to the next. Aircraft mechanics need to access complex 3D models and supporting digital data across a range of device form factors (e.g., large touch displays, tablet screens, smartphones) and need to move fluidly between these heterogeneous platforms during their work. Integrating digital data into the mechanic's workflow requires new forms of targeted, contextually-relevant information visualization and interaction. Finally, in order to situate complex digital information within the context of the aircraft, ubiquitous sensing infrastructures are required.
