The technique matches motion features from sensors on a mobile device to image motion features obtained from images of the device. For example, the acceleration of a mobile device, as measured by an onboard internal measurement unit, is compared to similar acceleration observed in the color and depth images of a depth camera. The technique does not require a model of the appearance of either the user or the device, nor in many cases a direct line of sight to the device. The technique can operate in real time and can be applied to a wide variety of ubiquitous computing scenarios."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fusing device and image motion for user identification, tracking and device association","description":"The cross-modal sensor fusion technique described herein tracks mobile devices and the users carrying them.
