Low Power Computing Environment by Adaptive Power Management to User's Context

本研究旨在降低前端资讯系统与使用者互动的功耗。用户并不总是请求这些系统进行处理。如果这些系统的组件通常关闭，除非用户要求，这将减少电力消耗。但是，这会让用户感到不愉快，因为他们必须等待所需的组件上电并准备好进行处理。为了解决这些问题，本研究提出了一种能够识别用户与系统交互中存在的用户上下文的自适应电源管理方法。该方法充分利用了上述用户环境，实现了自适应电源管理。将该方法应用于无线局域网接口、显示器和硬盘驱动器，结果表明，该方法既能降低功耗，又能满足用户的舒适度。

This research aims to reduce power consumption of front-end information systems which serves interactions with users. Users do not always request these systems for processing. It would reduce power consumption if components of those systems are usually powered off unless requested by users. However, it would make users unpleasant because they have to wait until the required components are powered on and get ready for processing. To solve these problems, this research proposes an adaptive power management which recognize user context which exist in the interaction between users and systems. The proposed method realizes adaptive power management by making full use of the above user context. The method is applied to wireless LAN interface, display, and hard disk drives and reveals that it satisfies both reduction of power consumption and comfort of users.
