SENSOR THAT DETECT EYE BLINKING

WEEK 4:

I had made research about the sensor that need to use to detect the eye and I had found a few type of sensor that used as sensor to detect  eye blinking and finally I choose IR sensor because it is suitable for make prototype.

IR Sensor (IR Receiver and IR Emitter)

    The basic principle of IR sensor is based on an IR emitter and an IR receiver. IR emitter will emit infrared continuously when power is supplied to it. On the other hand, the IR receiver will be connected and perform the task of a voltage divider. IR receiver can be imagined as a transistor with its base current  determined by the intensity of IR light received. The  lower the intensity of IR light cause higher resistance between collector-emitter terminals of transistor, and  limiting current from collector to emiiter. This change  of resistance will further change the voltage at the  output of voltage divider. In others word, the greater  the intensity of IR light hitting IR receiver, the lower  the resistance of IR receiver and hence the output mvoltage of voltage divider will decreased. Usually the  IR emitter and IR receiver will be mounted side by side,  pointing to a reflective surface. The further distance  away between emitter and receiver decrease the  amount of infrared light hitting the receiver if the  distance between the sensor and a reflective surface is  fixed.  Since the output voltage from voltage divider varies  with the intensity of IR light, and microcontroller is not  used in this project, a comparator (LM324) is used to show the changes. The eye-blink sensor works by illuminating the eye and/or eyelid area with infrared light, then monitoring the changes in the reflected light using a phototransistor and differentiator circuit. The exact functionality depends greatly on the positioning and aiming of the emitter and detector with respect to the eye.

WEEK 3

In final year project (semester 1 ) ,we need to show the research progress . In unikl bmi, we had given a choice to choose whether update the research progress in Log book or in the blog. My adviser had asked me to create a blog to update the progress of every meeting and all the result of my research must be updated in this blog also. I preferred to update the progress in blog than in log book. This is one of the way of learning process toward the excellent in future. And we have to send our blog address to RPS bmi and to adviser .

Accident statistic in Malaysia

Why I choose this projects as my final year projects. Based on the statistics above show that from day to day, week to week , month to month and year to year , the statistics of the accident happened had increased . By looking at the newspaper , the main problem why accident happened because of driver become asleep after a long journey. By looking at this problem I get an ideas in develop the projects that help driver to awake from the sleep when they become sleepy . This will help to increase the accident statistics in malaysia . 

WEEK 1 & WEEK 2

As a one of the candidate for Final Year Project for Semester 1,we have to choose lecturer to recommend and supervise student .Student have to consult with the adviser time to time and report to them the progress of the project. I had decided to choose SIR IZWAN ARIEF  from electronic section to monitor me in making final year projects . After choose my adviser, I had met him and asking whether he agree to supervise me in making my final year project and ALHAMDULLILAH , he agreed and he had told me make research in project that I want to do and bring the simple proposal on the next day to ask for his opinion. During my research , I had read an article about the accident happened on the highway because of driver fell asleep while driving and this article had attract me in producing something that can decrease the accident statistic in Malaysia. After make a research and with my trustful decision, I had decided to make "eye detection for accident prevention". On the next day I had presented my ideas to my supervisor and finally he approved my title. From now and the next week , I need to research about my final year project to get more ideas in producing this project which is my aim is to decrease the statistics of accident happened in Malaysia.
