Abstract
A central controller for device automation can control output devices (e.g. automated lights and speakers) based on calculating the indoor location of a person. In familiar surroundings (e.g. homes), people may leave their favorite wireless devices unattended (e.g. smartphones and tablet PCs) and in general people exhibit varying proximity to their mobile wireless devices. Hence, the indoor locations of mobile wireless devices are of variable importance when calculating indoor occupant locations. (e.g. exhibiting highly-correlated locations when handheld). In one embodiment, the central controller aggregates wireless signals from mobile wireless devices. The central controller calculates one or more mobile device location estimates and person-to-device proximities from the wireless signals. The central controller uses each person-to-device proximity to weight the corresponding mobile device location in a calculation to estimate the occupancy of the region of the building and controls an output device based on the occupancy estimate.
