The goal of this project is to establish a research program to enable mobile app designers to conduct user testing on low fidelity or paper prototypes in realistic environments. Mobile app usage now accounts for over half of all time spent on digital media. Current practice is that realistic testing of new apps tends to occur only after the development of high-fidelity prototypes, which can take weeks or months to implement. The PI will build and evaluate tools, and develop methodologies, for remote paper prototype testing that will enable designers to facilitate testing sessions from the lab while users remotely interact (via a Wizard-of-Oz mechanism) with a low-fidelity prototype that can be generated in just a few hours. The PI's goal is to accelerate mobile app development by making it possible for designers to observe and gather valuable feedback from users in realistic scenarios early in the design process; as a consequence, designers will be empowered to test multiple ideas and iterate on them quickly, with the potential for order-of-magnitude increases in the rate of innovation at lower cost in terms of both monetary and human resources. The PI will make his tools available to a wide community of researchers and design practitioners by releasing all software artifacts to the general public under open source and creative commons licenses, and by providing implementations that rely only on existing, off-the-shell technologies.The PI will design, implement, and evaluate remote paper prototype testing tools that preserve and extend the affordances of paper prototyping to the mobile setting while supporting the design goals of testing mobile apps in realistic locations and situations of use, of facilitating a testing session and wizarding a paper prototype remotely, and providing location-based and situational context. For example, users will test a paper prototype out of the lab while a designer wizards from afar. A paper prototype placed under a video camera in the lab streams an audio-visual feed to the tester's mobile device, while a device on the user streams an audio-visual-data feed to the facilitator and wizard, including the user's first-person perspective, their talk-aloud, and other relevant data, such as their location. To operate the prototype from afar, a wizard responds to the user's actions and situational context based on the live stream from the user. Any alerts or updates to the prototype are streamed to the test user's mobile device. The PI will collaborate in this research within Northwestern University with the Segal Institute of Design, the Design, Technology, and Research program, Design for America, and the NUvention program. Effectiveness of the developed methods and tools will be evaluated through controlled experiments and field deployments. Project outcomes will contribute to our understanding of low-fidelity prototyping and wizard-based techniques for remote testing.

该项目的目标是建立一个研究计划，使移动的应用程序设计师能够在现实环境中对低保真度或纸质原型进行用户测试。移动的应用程序使用现在占数字媒体所有时间的一半以上。 目前的做法是，对新应用程序的实际测试往往只发生在开发出高保真原型之后，这可能需要数周或数月的时间才能实现。 PI将构建和评估远程纸质原型测试的工具，并开发方法，使设计人员能够在用户远程交互（通过绿野仙踪机制）的同时促进实验室的测试会话，该原型可以在几个小时内生成。 PI的目标是加速移动的应用程序的开发，使设计师能够在设计过程的早期观察和收集来自现实场景中的用户的有价值的反馈;因此，设计师将有权测试多个想法并快速对其进行验证，并有可能以较低的资金和人力资源成本实现创新率的数量级增长。 PI将通过在开源和知识共享许可证下向公众发布所有软件工件，并通过提供仅依赖于现有的现成技术的实现，使他的工具可用于广泛的研究人员和设计实践者社区。PI将设计，实现，并评估远程纸上原型测试工具，这些工具在支持测试设计目标的同时，保留并扩展了纸上原型的功能，使之适用于移动的环境移动的应用程序在现实的位置和使用情况下，促进测试会话和远程向导纸上原型，并提供基于位置和情景的上下文。 例如，用户将在实验室外测试纸质原型，而设计师则在远处进行向导。 放置在实验室摄像机下的纸质原型将音频视频馈送流传输到测试人员的移动终端，而用户身上的设备将音频视频数据馈送流传输到辅导员和向导，包括用户的第一人称视角、他们的大声说话以及其他相关数据，例如他们的位置。 为了从远处操作原型，向导基于来自用户的实时流来响应用户的动作和情境上下文。 原型的任何警报或更新都将流传输到测试用户的移动终端。 PI将在西北大学与Segal设计研究所，设计，技术和研究计划，美国设计和NUvention计划合作开展这项研究。 将通过受控实验和实地部署来评估所开发的方法和工具的有效性。 项目成果将有助于我们理解低保真原型和基于向导的远程测试技术。
