Embodiment Construction

[0031] The present principles are directed to indoor localization or identification of indoor locations. While the various applications to which the present principles can be applied will readily occur to those of ordinary skill in the art, the following description will focus on embodiments in which the present principles are applied to indoor environments such as homes and mobile devices for positioning, which Mobile phones such as mobile phones or other mobile devices including wearable devices such as virtual reality (VR) or augmented reality (AR) devices such as headsets or helmets. However, given the teachings of the present principles provided herein, one of ordinary skill in the art will readily envision other devices and applications to which the present principles may be applied while maintaining the spirit of the present principles. For example, the present principles can be applied to other indoor environments, such as business establishments or office areas. Furt...

Abstract

Apparatus and method for indoor localization involving sampling illumination in a location such as a room of a building, producing a frequency domain analysis of the illumination, comparing the frequency domain analysis to a reference frequency domain analysis associated with a reference location, and providing a notification indicating a result of the comparison such as whether the location of the sampling is the reference location.

Description

technical field [0001] The present principles generally relate to indoor localization or position detection. Background technique [0002] Indoor location determination or indoor localization is an unsolved problem. GPS, although effective outdoors, is not available indoors (eg, at home) due to the inability of GPS devices to acquire GPS satellite signals indoors. Many services and applications can benefit from scalable indoor positioning technology. Such applications range from indoor location-based advertising to tracking elderly people at home to ensure their health. [0003] One method of indoor positioning is the use of radio beacons. For example, Apple's iBeacon uses Bluetooth Low Energy. This requires the installation of infrastructure (beacons) and is not reliable due to multipath effects of radio frequency signals. It's also not very person-centric, since radio waves travel through walls and it can be difficult to determine exactly which room a person is in. T...
