OBJECT LOCALIZATION METHOD, SYSTEM, TAG, AND USER INTERFACE DEVICE
First Claim
1. A method for locating an object comprising a light sensitive tag within an environment having a lighting infrastructure associated therewith, the method comprising the steps of:
- identifying the object,providing an illumination device from the lighting infrastructure, the illumination device comprising a plurality of light sources modulated to emit light comprising light source identification codes,illuminating the tag with the light,causing the tag to measure the illumination and to identify the light sources illuminating the tag by their light source identification codes,transmitting object location data from the tag relating to the measured illumination and light source identification codes to a master controller arranged to control the illumination device,providing a feedback signal related to the object using the master controller.

Abstract
Proposed is an object localization method, system and user interface device for locating a (misplaced) object (10) in an area of a construction (1). The method comprises the steps of (i) identifying the object (10), (ii) providing an illumination device (20) comprising a plurality of light sources (30) modulated to emit light comprising light source identification codes (35), (iii) illuminating the tag (11) with light emitted by the light sources (30), (iv) requesting the tag (11) to measure the illumination and to identify the light sources (30) illuminating the tag by their light source identification codes (35), (v) transmitting object location data from the tag (11) relating to the measured illumination and light source identification codes (35) to a master controller (25) arranged to control the illumination device (20), (vi) providing a feedback signal related to the object (10) using the master controller (25). The method is characterized by using a lighting infrastructure (27) of the construction (1) in providing the illumination device (20). Advantageously, the method enables a user to obtain a feedback signal about the location of the desired object without the need to move through the construction. Instead, the method enables the user to locate many objects within a construction or area from a single fixed position.
