Abstract

This paper proposes a new application or user model for emerging Bluetooth Technology which allows a user to have a flexible personal monitoring system which ensures object(s) being monitored are always within a certain range from the master. Some advantages provided by the personal monitoring system include: mobility (Monitoring zone moves with the master monitoring device, operating in unlicensed band (universal), low cost solution (as Bluetooth technology is used).

PERSONAL MONITORING SYSTEM USING BLUETOOTH TECHNOLOGY

by Ong Dee Nai

INTRODUCTION:

This paper proposes a new application or user model for emerging Bluetooth Technology which allows a user to have a flexible personal monitoring system which ensures object(s) being monitored are always within a certain range from the master. Some advantages provided by the personal monitoring system include:

mobility (Monitoring zone moves with the master monitoring device)

operating in unlicensed band (universal)

low cost solution (as Bluetooth technology is used)

DETAILED FEATURES DESCRIPTION:

Two proposed uses are described below:

A) Child Monitoring Helper

Parents could make use of the proposed personal monitoring system to assist them in keeping an eye on their children while shopping. The system comprises one master monitoring device and one or more slave devices.

A Bluetooth-capable device which could either be stand-alone or built into a mobile phone carried by a parent acts as the master device while a Bluetooth-capable device which, for instance, could be attached to a child, acts as the slave device to be monitored/tracked.

When the child is within the coverage zone (which is typically ~l0meters in radius but can be made user configurable to a smaller/larger zone range), both the master and slave devices will remain silent and periodically communicate between each other to ensure they are not apart by more than a predetermined distance. Once one or more of the slave devices are found to be out of the monitoring zone of the master, the master device will emit some indications, such as an audible alert, to alert the parent that at least one of the children being monitored has moved out of the monitoring zone.

In addition, the slave device could also be designed to emit an audible alert to assist the parent in locating one or more of the children.

B) Personal Belonging Watchdog

This system is suitable for travelers with a number of pieces of luggage. A slave device will be attached to each piece of luggage.

When the owner forgets and leaves a piece of luggage, both the master and the corresponding slave device will provide an alert to remind the owner that a piece of luggage was left behind (in this case, the system serves as reminder).

In addition, this system could help to alert the owner when one of the tracked pieces of luggage is taken out of monitoring range (in this case, the system serves as alerting alarm)

IMPLEMENTATION CONSIDERATIONS:

Every slave device of the personal monitoring system is assigned a unique id. The master device instructs each of the slave devices the rate of status update (i.e. how often the slave device needs to transmit an "I'm (still) here!" message) and transmit power (for adjusting monitoring zone range).

Each of the slave devices transmits a presence notification (...
