Abstract

Knowing the position of a device such as a smartphone accurately enough to control another device is a complex problem. Specific solutions (such as inertial measurement units) exist, but they are relatively expensive while do not provide accurate positioning over extended periods of time. In this project we explored methods based on the physical properties of sound to achieve quality positioning with affordable and relatively easy to set up equipment. Different options have been tested and we have chosen to use the Doppler effect to determine the speed of movement of the device and calculate its position in both 2D and 3D environments. Multiple tests have been performed demonstrating the advantages of the proposed method and pointing out the most important limitations. Finally, a demonstrator of the proposed technology has been developed to use a smartphone as a video game controller.

Keyphrases: Android device tracking, Doppler effect, Low Cost Tracking, Sound-based tracking
