WiiLoc: A step towards efficient device identification in large office buildings by Wii-based localization

In the context of building automation, one of the many tasks is to localize and identify thousands of sensors and actuators, such as smoke detectors, switches, light bulbs, and window blinds. Since performing this task by hand is too costly and error-prone, this paper proposes a simple, semi-automatic system, called WiiLoc, for this task. WiiLoc employs two infrared cameras, a three-dimensional acceleration sensor, and an electronic compass, and yields a localization error of as low as 2% with respect to the distance to the object. SinceWiiLoc employs only simple standard components, such as the Wii remote control, the costs will be below 150 Euro.
