Abstract

A method and system is disclosed for tracking location of one or more devices/users in motion using Bluetooth Low Energy (BLE) chips. The method and system, then, determines the location of the one or more devices/users in motion based on signal strengths of BLE signals received from the one or more devices/users. The method and system, further, provides interaction capabilities to the one or more devices/users based on the tracked location.

Method and System for Tracking Devices/Users in Motion using Bluetooth Low Energy Chips

Abstract

A method and system is disclosed for tracking location of one or more devices/users in motion using Bluetooth Low Energy (BLE) chips.  The method and system, then, determines the location of the one or more devices/users in motion based on signal strengths of BLE signals received from the one or more devices/users.  The method and system, further, provides interaction capabilities to the one or more devices/users based on the tracked location.

Description

Disclosed is a method and system for tracking location of one or more devices/users in motion using Bluetooth Low Energy (BLE) chips.  The method and system, then, determines the location of the one or more devices/users in motion based on signal strengths of BLE signals received from the one or more devices/users.  The method and system, further, provides interaction capabilities to the one or more devices/users based on the tracked location.

In an embodiment, the method and system implements a peripheral device that features two BLE chips which are positioned at opposite ends of the peripheral device for tracking one or more BLE-capable user carried devices (tracked devices).  The peripheral device can include, but need not be limited to, a TV unit, a customer tracking device in a store or a mall, a home automation system.  Offsetting the two BLE chips at either end of the one or more peripheral devices provides sufficient accuracy for locating the one or more devices/users within a room or an open space.

FIG. 1 illustrates a basic setup of the method and system, wherein the peripheral device utilizes two BLE chips in accordance with the embodiment disclosed herein.

Figure 1

In accordance with FIG. 1, when one of the BLE chips (BLE CHIP 1) inside the peripheral device is in discovery mode (“peripheral mode”), the method and system enables the one or more tracked devices to discover the peripheral device and connect to it.  Once connected, the method and system supports all traditional interactions for the one or more tracked devices, including, but need not be limited to, finding own indoor location and communication.  For example, the one or more tracked devices connect to the TV unit to exchange information, query settings or send one or more commands (as a remote control).  The connection also allows the TV unit to learn about the one or more tracked devices, owner/user of the one or more tracked devices and to personalize content when used as a remote control.

When at least one of the tracked device connects to the one BLE chip in peripheral mode due to scanning activities, the BLE chip in peripheral mode detects a signal strength of the at least one tracked device and infers a rough distance to the device indicated as d2 in FIG. 1.

When the second BLE chip in the peripheral device is in central mode, the method and system constantly scans for one or more BLE advertisement pack...
