| Research Abstract |
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.
