Improve the Performance of the Android Operation of External Human Interaction Device

摘要

Smart phones become popular. They have various sensors and connection modules. They employ a mobile operating system for the control of sensors and modules. In this situation, a large amount of data comes to the operating system from sensors and modules. While such data is important for effective operations of smart phones, it is not well known that how it affects the operating system performance. In this paper, we prepare an experiment environment that mimics a smart phone. We selected the Android as an operating system and the Panda board-ES as a target board. The Panda board-ES equips a Bluetooth module. We select Wii Remote to operate the Android via Bluetooth. We implement programs to use Wii Remote as the input device of the Android, and improve this program.
