摘要

This article proposes a solution for user localization in indoor areas using the compass, accelerometer and Bluetooth of a mobile device to calculate the user's position within this virtual environment, for it to be used in both entertainment-industry mobile games and serious games. The user's position is viewed through a 3D virtual environment representing his real position and orientation. The basis of this solution is the utilization of a mobile Bluetooth-enabled device, such as a PDA, where the application is deployed. The application will then use the mobile phone's Bluetooth to determine the Received Signal Strength Indicator (RSSI) of beacons located within the area. This information is then used to determine the virtual position of the user by triangulation. Additional sensors, such as the accelerometer or the compass provide extra precision and compensate the latency that the Bluetooth positioning solution provides. This solution has proved to be reasonably accurate, inexpensive, and very usable, as it uses virtually no input from the user (since the input the user provides is actually passive). Also, it does not conflict with any other Bluetooth devices, such as other mobile phones.
