Device Movement Detection

Amazon Lab126 is an American research and development and computer hardware company owned by Amazon.com. It was founded in 2004 by Gregg Zehr, previously Vice President of Hardware Engineering at Palm, and is based in Sunnyvale, California. Consumer radars are enabling wireless based sensing applications for smarthome. Certain radar applications rely on fixed device placement to function properly. For example, locating movements of subject with respect to the map of customer environment. Fixing the devices (i.e. wall mount) is not always an option. A method to detect the device has been moved and no longer "looking" at the same scene is required to notify user to take corrective actions. Otherwise, there will be missing data or false alarms that lead to poor customer experience. While this may be achievable with other sensors, there is a desire to minimize cost to solve this with radar itself. This student team sought to deliver a signal processing based software module that can output if the device has been moved out of its original position and orientation.
