Vision-Based Eye-Gaze Tracking for Human Computer Interface
Human-computer interaction has become an increasingly important part of our
daily lives. The movement of user’s eyes can provide a convenient, natural and
high-bandwidth source of input. By tracking the direction of gaze of the user,
the bandwidth of communication from the user to the computer can be increased by using
the information about what the user is looking at, and even designing objects
specially intended for the user to look at.
A variety of eye-gaze (eye-movement) tracking techniques have been reported in
the literature. A short list includes Electra-Oculography, Limbus, Pupil and
Eyelid Tracking, Contact Lens Method, Cornea1 and Pupil Reflection Relationship,
Purkinje Image Tracking, Artificial Neural Networks and Head Movement
Computer vision is intrinsically non-intrusive, and does not require any overly
expensive equipment. Nonobtrusive sensing technology – such as video cameras and
microphones – has received special attention in this regard. This paper draws on
computer vision and image processing techniques for measuring eye-gaze
GSM Based SMS Driven Automatic Display Toolkit for College Noticeboard
The main aim of the project will be to design a SMS driven automatic display
toolkit which can replace the currently used programmable electronic display. It
is proposed to design receive cum display toolkit which can be programmed from
an authorized mobile phone.
The message to be displayed is sent through a SMS from anauthorized transmitter.
The toolkit receives the SMS, validates the sending Mobile Identification Number
(MIN) and displays the desired information after necessary code conversion.
The system is made efficient by using ‘clone’ SIMs of same MIN in a geographical
area so that the same SMS can be received by number of display boards in a
locality using techniques of time division multiple access. Started of as an
instantaneous News display unit, we have improved upon it and tried to take
advantage of the computing capabilities of microcontroller. We envision a
toolkit that will not only display message but also can be used to do some
Looking into current trend of information transfer in the campus, it is seen
that important notice take time to be displayed in the notice boards. This
latency is not expected in most of the cases and must be avoided.
Deriving Activity from RFID Detection in an Assisted Living Context
There has been a significant growth in the deployment of Radio Frequency
Identification (RFID) in the supply chain in the recent years. Since RFID
requires less cost and infrastructure than the sensor networks such as
Ultrasonic or Wi-Fi, it has been applied in many business and research
The major applications of RFID technology include location position, object
tracking and activity monitoring. Particularly in the individual activity
monitoring circumstance, it is expected that by detecting the object with which
the person interacted, the related personal movement is able to be recognized.
However, the inherent unreliability of RFID data results in the uncertainty of
the RFID detection of activity.
This research estimates the accuracy of using RFID detection records to monitor
personal activity in an assisted living context. The methodology for this
research is a quantitative approach by using design science. Two real
experiments are conducted for performing activity monitoring in a laboratory
environment. Both experiment results show that false positive reads have a
serious influence on the accuracy of detecting individual motion. In order to
remove the noisy data from the original RFID data stream, the multi-level data
pre-processing method is used and analysed in the research. The cleaned dataset
shows the perfect accuracy of personal activity inference.
Although this proposed method is efficient for filtering the noisy data and
predicting the correct individual movement in this research, it only focuses on
recognizing the regular personal activity in a clean indoor environment. Due to
the complexity of human indoor behaviour, future exploration needs to be carried
out in other different environmental backgrounds.
for high-performance embedded processing
Modern embedded markets call for high density computing ability, making it is
difficult to use just one microprocessor to meet function requirements of
highperformance embedded systems. Multiple processors, including general-purpose
embedded microprocessors, digital signal processors (DSPs), ASICs and FPGA
hardware accelerators, are often used in these embedded systems.
Not all processors in an embedded device have the same characteristics and
they are asymmetric. Heterogeneous multiprocessors bring forward difficulties in
both hardware and software designs. The paper addresses the issues of supporting
parallelization in asymmetric multiprocessor (AMP) environment from both
hardware and software sides, including cache coherence, semaphore and
embedded software programming.
With the development of silicon technologies, embedded chips become more
powerful and have more dense computing ability. Embedded processors take the
place of general-purpose PC processors not only because of their low cost but
also because of their low power consumption, rich functionality and high
Adaptive Missile Guidance Using GPS
In the modern day theatre of combat, the need to be able to strike at targets
that are on the opposite side of the globe has strongly presented itself. This
had led to the development of various types of guided missiles. These guided
missiles are self-guiding weapons intended to maximize damage to the target
while minimizing collateral damage.
The buzzword in modern day combat is fire
and forget. GPS guided missiles, using the exceptional navigational and
surveying abilities of GPS, after being launched, could deliver a warhead to any
part of the globe via the interface pof the onboard computer in the missile with
the GPS satellite system.
Under this principle many modern day laser weapons were designed. Laser guided
missiles use a laser of a certain frequency bandwidth to acquire their target.
GPS/inertial weapons are oblivious to the effects of weather, allowing a target
to be engaged at the time of the attacker’s choosing.
Power Harvesting Circuit
To facilitate data transfer in adverse RF propagation environments (1/r^3 loss),
the chip receives a 1 Mbps data signal with a sensitivity of -90 dBm while
consuming just 1.6 nJ/bit. The receiver operates without the addition of any
external passives facilitating its application in Smartdust scale (mm^3)
wireless sensor networks. This represents an order of magnitude decrease in
power consumption over receiver designs of comparable sensitivity.
In an effort to further extend the lifetime of the transceiver, RF power
harvesting is explored as a power source. The small scale of sensor networks
poses unique challenges in the design of RF power scavenging systems. To meet
these challenges, novel design improvements to an RF power scavenging circuit
integrated directly onto CMOS are presented. These improvements include a
reduction in the threshold voltage of diode connected MOSFET and sources of
circuit parasitics that are unique to integrated circuits.
As the capability and complexity of robotic platforms continue to evolve from
the macro to micro-scale, innovation of such systems is driven by the notion
that a robot must be able to sense, think, and act.
The traditional architecture of a robotic platform consists of a
structural layer upon which, actuators, controls, power, and communication
modules are integrated for optimal system performance. The structural layer, for
many micro-scale platforms, has commonly been implemented using a silicon die,
thus leading to robotic platforms referred to as “walking chips”.
A Low-Cost Efficient Wireless Architecture for Rural Network Connectivity
Many rural regions around the world, especially in developing regions, do not
have good connectivity solutions which are economically viable. As a result,
many of these regions remain disconnected from both the rest of the world and from
progress in general.
In this proposal, I will describe the design of WiFi-based Rural Extensions (WiRE),
a new wireless network architecture that can provide connectivity to rural
regions at extremely low costs. The WiRE architecture is tailored for the
typical rural landscape in several developing regions, in which the population
is spread across small but scattered rural regions (less than 1-2 sq kms) within
100-200 kms of the city. WiRE is designed to be a wireless distribution network
that extends connectivity from the city to each village.
Biometric Fingerprint Identification
Identification of individuals is a very basic societal requirement. Electronic
verification of a person’s identity is of great importance as more interactions
take place electronically. Biometric fingerprint identification is a technique
used to change thephysical attribute of a person ie; his finger print into
Until recently electronic verification was based on something the person had in
their possession like a password. But the problem is that these forms aren’t
very secure because passwords can be forgotten or taken away.
In biometric finger print identification a scanner is used to get the image of
the finger. When a user places his or her finger on the terminals of scanner the
image is electronically read, analysed and compared with a previously recorded
image of the same finger, which has been stored in finger scan data base. Finger
print is a proven technology capable of high levels of accuracy.
Automatic Street Light Control System
Automatic Street Light Control System is a simple and powerful concept, which
uses transistor as a switch to switch ON and OFF the street light automatically.
By using this system manual works are removed. It automatically switches ON
lights when the sunlight goes below the visible region of our eyes. It
automatically switches OFF lights under illumination
by sunlight. This is done by a sensor called Light Dependant Resistor (LDR)
which senses the light actually like our eyes.
By using this system energy consumption is also reduced because now-a-days the
manually operated street lights are not switched off properly even the sunlight
comes and also not switched on earlier before sunset. In sunny and rainy days,
ON time and OFF time differ significantly which is one of the major disadvantage
of using timer circuits or manual operation.
This project exploits the working of a transistor in saturation region and
cut-off region to switch ON and switch OFF the lights at appropriate time with
the help of an electromagnetically operated switch.
Automatic Streetlight needs no manual operation of switching ON and OFF. The
system itself detects whether there is need for light or not. When darkness
rises to a certain value then automatically streetlight is switched ON and when
there is other source of light, the street light gets OFF. The extent of
darkness at which the street light to be switched on can also be tailored using
the potentiometer provided in the circuit.
Moreover, the circuit is carefully designed to avoid common problems like
overload, relay chattering and inductive kick back in relay.
Walking Stick with Heart Attack Detection
The ECG circuitry unit on the wrist captures abnormal heart beat signal from the
patient. The micro controller on the stick runs a heart attack algorithm.
Warning is given out to the person about his heart condition. The Bluetooth
emergency calling system calls for medical help at the moment of heart attack.
This project aims to shorten the time between the moment of heart attack and
thearrival of medical personal. The warning before the emergency call will give
the patient a chance to avoid heart attack.
Two biosensors worn on the user’s wrists send the real ECG signal to the analog
ECG circuitry. The amplified and filtered analog output of the circuitry is
converted from analog to digital signal and transmitted to the unit on the
walking stick. The ECG circuitry unit, the A/D converter, and the transmitter
are worn on one of the user’s wrists. The wireless connection between the unit
on the wrist and the main unit on the walking stick gives the user more freedom
to move by avoiding wire attachment between the wrist and the stick.
The receiver on the stick receives the digital ECG signal, and the
microcontroller runs a heart attack algorithm to detect possible heart attack
symptoms. If any symptom of heart attack is detected, the risk level rises. When
the risk level reaches up to the emergency mode, the Bluetooth module activates
the user’s mobile phone to call 911 for medical help.
Laser Guided Vehicle
The work done in this master thesis concerns laser guided vehicles, and more
specifically the autonomous navigation by following the edge of a road. The idea
is that using two synchronized lasers on top of each other would increase the
robustness of the road detection, compared to only one laser.
The algorithm was developed in Matlab, using a sequence ofscans recorded on a
snowy road with snow piles on the sides. The road detection uses the Hough
transform for each scan. The relative position of the robot on the road is then
estimated from the road edges detections. The control law is based on the
Simulations were done in Matlab, and a few tests have also been done on the MICA
wheelchair. The algorithm was successful when following a straight corridor, but
some more work has to be put into dealing with intersections, and on predicting
Robo Design to pick everyday objects
In this project, you can learn how robotic technology can improve the lives of
people with disabilities to help them pick everyday objects. In the laboratory,
Lego Mindstorms NXT kits are used to create an artificial arm or hand that can
lift small objects, such as a coffee cup.
In the process, you can discover and explore the following concepts and ideas:
Hooke’s Law, hysteresis,
Second Law, accuracy and precision, rapid prototyping, and the relationship
between the voltage applied to a motor and its speed.
Audio Guidance System for the Blind
The main goal of the project is to provide a cost-effective way to allow
buildings to support blind people.
The Blind Audio Guidance System hopes to allow visually impaired users to simply
press a button, speak the desired destination, and be guided there with the use
of audio instructions.
The system hopes to provide a portable unit that can easily be carried and
operated by a visually impaired user. It could easily be incorporated into a
Many different design possibilities were explored during research.
Wireless Sensor Networks – Due to the high amount of sensors required for large
buildings, this may be impractical, especially when user direction must be
tracked. Programming would be much more complex.
RSSI Techniques – This can be effective at finding distances base on signal
strength but is also affected by the direction problem.
RFID – Seems to provide the most cost effective and simplest way to determine
direction using the technique that the team has developed. The programming using
this technique would also be less complex.
and LCD display
This Project is used to indicate the temperature and it is
also used as controller. The system will get the temperature from the DS1820 and
it will display the temperature over the LCD display. There are 2 preset levels,
one is low preset and the other is High preset. The temperature was compared
with the value stored by the user and if the temperature goes beyond the High
Preset temperature then an relay is switched ON until the temperature comes
below the Low preset temperature.
The System is fully controlled
by the microcontroller AT89S52. It is a popular 8 bit microcontroller. The
circuit consists of four switches, in which two buttons are used to increment
and decrement the High limit temperature value and the other two buttons are
used to increment and decrement the Low limit temperature value.
The temperature limits are
stored inside the EEPROM, since 89s52
dont have inbuilt
eeprom. The IC 24C02 is
the eeprom chip and it is connected to the microcontroller through the I2C bus.
The DS1820 is the temperature sensor chip which is connected to the
microcontroller through 1 wire bus.
level alarm using 8051 microcontroller
article illustrates the construction and working of a liquid level indicator.
Such an indicator is used in tanks to indicate the level of liquids and alert us
when the tank is full. So by this circuit we can monitor the various levels of
the tank and can avoid spillage of water and also we can configure our supplies
according to the various levels of tank. Such module or circuit can be installed
in big buildings where manual monitor of tanks is difficult and its indicator
can be placed at some centralised place
Initially when the
tank is empty LCD will show the message VACANT.
As the tank starts filling up wire at different levels get some positive
voltage, due to conducting nature of water. This voltage is then fed to their
corresponding pins on controller. When level reaches to quarter level, LCD
displays the message
On further rise of level, HALF and 3/4
displayed on LCD. When tank gets full LCD shows the message FULL
A buzzer is also provided to produce a alert the user when the tank gets filled.
This buzzer can be made off by pressing the switch connected between pin 15 of
controller and VCC.
thermometer using 8051 microcontroller
Fahrenheit scale digital
thermometer is a temperature indicator which displays temperature in Fahrenheit
scale. It is similar to Celsius
scale digital thermometer,
except a little modification in the microcontroller program. The temperature
sensed in Celsius scale in the Celsius scale thermometer project is converted
into the Fahrenheit scale temperature just by using the Celsius to Fahrenheit
conversion formulae. This project also uses 8051 microcontroller (AT89C51).
A digital thermometer can be
easily made by interfacing a temperature sensor to the microcontroller AT89C51.
The temperature sensor used in the project isLM35.
The LM 35 IC generates a 10mV variation to its output voltage for every degree
Celsius change in temperature. The Output of the temperature sensor is analog in
nature so we need an analog to digital convertor for converting the analog input
to its equivalent binary output. The ADC
the analog to digital convertor IC used in the project. 0804 is a single channel
convertor which converts the analog input up to a range of 5V to an equivalent
8-bit binary output.
measurement using InfraRed sensor
Infrared sensors find
numerous applications in electronic systems. Commonly used as obstacle detector,
their output is used in digital form (high & low logic) by employing a
comparator. This topic explains a way to use the sensor’s output in its
original analog form. Thus, along with detecting an obstacle, its exact distance
can also be obtained. This is achieved by processing the output of IR sensor
through an ADC0804 (analog
to digital converter). The ADC is calibrated to get almost accurate distance
The measured distance
is also displayed on an LCD screen. The ADC0804 and LCD are interfaced with 8051
to perform these operations. The major drawback of IR based sensors is their
capability of detecting short distances.
receiver detects the IR radiations transmitted by an IR
LED. The output
voltage level of this IR sensor depends upon the intensity of IR rays received
by the receiver. The intensity, in turn, depends on the distance between the
sensor module and the obstacle. When the distance between IR pair and obstacle
is lesser, more IR radiations fall on the receiver, and vice versa. The receiver
along with a resistor forms a voltage divider whose output is supplied as the
input for ADC0804.
How to interface Humidity with 8051 Microcontroller
Physical quantities like Humidity, temperature, pressure etc. are monitored to
get information about the environmental conditions. Various sensors are being
used to measure these quantities in analog form. This article demonstrates the
principle and operation of interfacing the humidity sensor with 8051
microcontroller (AT89C51). The
humidity sensor is widely used in applications like weather forecast, air
conditioner, Hygrometers etc.

8051 Based Electronic Eye
This project is based on high
sensitive IR Transmitter & Receiver having range of more than 15 feet. When you
are away for your house any if anyone tries to enter the house by any means the
device shouts THEIF THEIF Continuously more than 40 seconds, that is enough to
chase the thief, he will run away so your house is protected. The device not
only shouts but also dials out previously stored telephone number ( which you
have stored) and gives you the message THEIF. So that you understand that
something is wrong at your house, you can immediately call up your neighbor to
look after your house.
RFid Based Museum Guide for Tourists
RFID enabled tour assistant is
expected to replace tourist guides to an extent. Its a voice enabled device that
speaks out as the tourist is traveling from places to places (museum). When the
tourist is standing near major landmarks, it will detect the RFID tag and will
play an audio clip relevant to that location. This is achieved by placing a RFID
receiver with the tourist (palm device). as soon as the palm device comes in
the vicinity id the RF tag the microcontroller receives
the RF tag unique id from the receiver and matches it with it's own data base.
If match occurs the microcontroller will
play an audio clip relevant to that statue/painting. Audio files are tagged with
location coordinates and a tolerance range. In a particular location, the file
that matches the tolerance range are played.
Industrial Automation using
Now days, marketing demands
are increasing continuously. If you can't satisfy demand then you will knock out
of the race. There is no time limit for work. So in modern industry, it needs to
give alignment without going on field. Our project satisfies this need by using
a GSM modem.
Consider one case, that you are field
engineer, company will start at 9 o'clock. But you
have to turn on boiler at 7 o'clock to start
working at 9 o'clock. In this case you
have to go at 7 o'clock but by using this
project you can start boiler by just giving command from your mobile. Boiler is
just example you can turn on or turn off any controlling device.
Now consider another case, you need to monitor few parameters in the industry,
say Humidity in a paint
shop machine or a critical thing like LPG gas
leakage, then you need to be present in the industry/plant. The second part of
our project meets this requirement, it monitors the parameters on the LCD and at
the same time sends a sms containing the values of these parameters.
For controlling the relays, you
have to send sms the GSM modem which you
have set on field. This GSM modem will
receive your SMS. Then particular relay is turned on/off by reading the sms.
Digital weather station with Data storage
Throughout time we"ve been fascinated by the weather - studying signs of change
and making and acting on predictions. Today we can link modern instruments to
computers to reduce human error and automate record keeping. Aim of the project
is to monitor weather conditions, including temperature, atmospheric humidity,
and solar light intensity. Local weather measurements are extremely important to
a wide range of professions, from horticulturists to fire fighters. It provides
around-the-clock monitoring of various types of applications. For example, it
can be used in a greenhouse to manage climate control and help promote favorable
growing conditions. In solar power applications, it can verify the performance
of photovoltaic (PV) array systems by monitoring solar radiation, DC power, and
other parameters. On green roofs, it can help researchers understand performance
by tracking air temperature, turf temperature, soil moisture, and rainfall.
Incubators are attracting interest from the medical profession. They are glass
and metal cases heated to certain Humidity, into which enough air is admitted to
maintain life. Until such time as infant is strong enough for Humidity of room.
In baby incubator Humidity control is
very important. And therefore we are controlling the Humidity according to our
requirements. Humidity controller can be done by using Electronic circuit, Microprocessor & microcontroller.
Now microcontroller is
advanced among all above circuits therefore we are using Microcontroller for
Humidity controlling of baby incubator
Public Garden Automation
The most important problems faced are the misusage of electricity and its
wastage. Sometimes due to carelessness of the authorities and the workers lamps
are left ON which results in wastage of electricity. Water wastage is another
problem which needs to be dealt with. Our project helps to overcome all these
Firstly the Microcontroller
around 4.00pm switches on the water supply once to water the entire garden few
hours before opening of the garden for public. Next the gate is opened by
running the motor which is driven by a motor driver operated by the
Microcontroller. At around 6.00pm the lights are switched on depending upon the
output of the LDR and the lights remain functional till the garden remains open
The garden remains open for
about three hours and so around 8.50 pm a buzzer is sounded to indicate closure
of the garden and alert the visitors. The gate is then closed at 9.00pm and
three of the four lamps are switched off. One lamp is kept on throughout the
night. In the morning the remaining lamp is switched off as the depending upon
the signal sent by the light dependent resistor to the Microcontroller. These
are the step involved in the operation of the circuit and the public garden
automation. Microcontroller is used to supervise the actions of all other
devices and to control the entire set of operations.
