| Abstract | If a mobile computing device knows how it is positioned and or iented in relation to other devices nearby, then it can provid e enhanced support for multi-device and multi-user interactio ns. Existing systems that provide position information to mobile com puters are reliant on externally deployed infrastructure, such as beacons or sensors in the environment. We introduce a novel system, R elate, which provides fine-grained relative position inform ation to co-located devices on the basis of peer-to-peer sensing, th us overcoming dependence on any external infrastructure. The syst m is realized as hardware/software plug-in, using ultrasound f or peer-topeer sensing, USB to interface with standard mobile devices , and data abstraction and inference to map sensor data to a spatia l model that maintains both quantitative and qualitative relation ships. We present a set of services and applications to demonstrate th e utility of the system. We report experimental results on the accu r cy of relative position and orientation estimation, and other aspects of system performance. |
