CRII: CSR: Rethinking Operating System Structure for Wearable Devices

CRII: CSR：重新思考可穿戴设备的操作系统结构可穿戴计算设备在教育、商业和医疗保健等领域发挥着越来越重要的作用。然而，可穿戴设备的主要指标，尤其是交互性能和能源效率，远不能令人满意。为了应对这一挑战，本CRII研究项目考察了可穿戴设备的关键组件，即操作系统，并探索了适合可穿戴设备独特特征的设计。可穿戴设备具有独特的外形因素和使用模型，以及高度专业化的工作负载，而操作系统实际上需要针对不同的工作负载进行专业化。该项目对当前和新兴硬件平台上现有的可穿戴工作负载进行了全面的描述，并提出了一套指导可穿戴操作系统设计的结构化原则，这些可穿戴操作系统可专门用于多种类型的工作负载。该项目开发了一个操作系统原型，其设计遵循这些原则，从而证明了这些原则的有效性。该项目利用与行业领导者的合作，促进对商业发展的广泛影响。项目成果将被整合到操作系统课程中。该研究项目提供了一个平台，让本科生参与可发表的研究，并向高中生和代表性不足的群体推广科学和工程。

CRII: CSR: Rethinking Operating System Structure for Wearable DevicesWearable computing devices are playing increasingly important roles in areas like education, business, and healthcare. However, the major metrics of wearable devices, most notably interactive performance and energy efficiency, are far from satisfactory. To address this challenge, this CRII research project examines the key component of a wearable device, namely the operating system, and explores designs that fit in the unique characteristics of wearable devices. Wearable devices have unique form factors and usage models, and highly specialized workloads, and the operating system needs to be virtually specialized for different workloads. This project develops a comprehensive characterization of existing wearable workloads on current and emerging hardware platforms, and a set of structuring principles for guiding the design of wearable operating systems that can be specialized for multiple types of workloads. The project develops an operating system prototype whose design follows the principles and thus demonstrates the effectiveness of the principles. The project leverages collaborations with industry leaders to foster a broad impact on the commercial development. The project outcomes will be integrated into the operating system course curriculum. The research program offers a platform for involving undergraduate students in publishable research and for promoting science and engineering to high-school students, and under-represented groups.
