Blue Eyes - Human - Operator Monitoring System Seminar Report
[attachment=67117]
Abstract
Imagine yourself in a world where humans interact with
computers. You are sitting in front of your personal computer that
can listen, talk, or even scream aloud. It has the ability to gather
information about you and interact with you through special
techniques like facial recognition, speech recognition, etc. It can
even understand your emotions at the touch of the mouse. It verifies
your identity, feels your presents, and starts interacting with you
.You ask the computer to dial to your friend at his office. It realizes
the urgency of the situation through the mouse, dials your friend at
his office, and establishes a connection
What is BlueEyes and what not?
BlueEyes – Bluetooth technology and the movements of the
eyes. Bluetooth provides reliable wireless communication
whereas the eye movements enable us to obtain a lot of
interesting and important information. This required designing a
Personal Area Network linking all the operators and the
supervising system.
BlueEyes system provides technical means for monitoring
and recording human-operator's physiological condition. The key
features of the system are:
Visual attention monitoring (eye motility analysis)
Physiological condition monitoring (pulse rate, blood
oxygenation)
Operator's position detection (standing, lying)
Wireless data acquisition using Bluetooth technology
Real-time user-defined alarm triggering
Why BlueEyes ?
Human error is still one of the most frequent causes of all
artificial disasters. Today human contribution to the overall
performance of the system is left unsupervised. Since the system
is made to perform automatically, an operator becomes a passive
observer of the supervised system, which causes drop to
awareness. It therefore is crucial to assure that the operator’s
conscious brain is involved in an active system which will
supervise over the whole work time period. It is possible to
measure indirectly the level of the operator’s conscious brain
involvement using eye movement analysis. In large control
rooms, wiring the operator to the central system is a serious
limitation of his mobility and disables his operation. The wireless
link between the sensors worn by the operator and the
supervising system offers new way to system overall reliability
and safety
System overview
The most important parameter in this system is saccadic
activity (Saccades are rapid eye jumps to new locations within a
visual environment assigned predominantly by the Conscious
attention process.), which enables the system to monitor the
status of the operator’s visual attention along with head
acceleration, which accompanies large displacement of the visual
axis (saccades larger than 15 degrees). Complex industrial
environment can create a danger of exposing the operator to toxic
DATA ACQUISITION UNIT (DAU)
Hardware specification of DAU
Atmel 8952 microcontroller to be the core of the Data
Acquisition Unit since it is a well-established industrial
standard and provides necessary functionality (i.e. high speed
serial port) at a low price. The figure below shows the other
DAU componentsBluetooth module used in the this project supports
synchronous voice data transmission (SCO link) .Developers
had decided to use hardware PCM codec to transmit operator’s
voice and central system sound feedback. Codec employed
reduces the microcontroller’s tasks and lessens the amount of
data being sent over the UART.
CENTRAL SYSTEM UNIT (CSU)
There are four main CSU modules (see fig: system
overview): Connection Manager, Data Analysis, Data Logger
and Visualization.
2.3.1Connection Manager
Connection Manager’s main task is to perform low-level
Bluetooth communication using Host Controller Interface
commands. It is designed to cooperate with all available
Bluetooth devices in order to support roaming. Additionally,
Connection Manager authorizes operators, manages their
sessions, demultiplexes and buffers raw physiological data.
LIMITATIONS AND FUTURE ASPECTS
The prototype has several limitations, which are not the
result of the project deficiency but are rather caused by the
constraints imposed by the Project Kit and small budget.
The unique feature of system relies on the possibility of
monitoring the operator’s higher brain functions involved in
the acquisition of the information from the visual
environment. The new possibilities can cover such areas as
industry, transportation (by air, by road and by sea), military
command centers or operating theaters (anaesthesiologists). It
is intended that the system in its commercial release will help
avoid potential threats resulting from human errors, such as
weariness, oversight, tiredness.
CONCLUSION
Human has tremendous expectations from human being’s
future and present. This tends to research new and helpful
technologies which can make the life more comfortable and
reliable. This technology is one of them that can make so.
Artificial disasters due to consciousness of human brain can be
overcome from those accidents.
