ABSTRACT          Blue eye is a technology which is being developedso that the machines get sensational abilities and perceptual abilities justlike our human beings .

These abilities make the computational machines to understandthe feelings of humans and this helps to interact with them. The main aim ofthis technology is to analyse human brain and understand their physiologicalconditions.KEYWORDSSensational, perceptual,wireless, hardware, software, data, information, bluedoothI.BLUE EYES TECHNOLOGY         Imagine a world where humans can communicatewith their computers. This concept was first developed by a research team in IBMat Almaden Research Center (ARC) in San Jose, California since 1997.This basedon the idea of Paul Ekan’s facial expression.

The etymology of the term blueeyes goes as blue stands for bluedooth technology which is wireless and the termeyes are used because it is the only part that helps us in finding the humanexpressions easily. The main aim of this technology is to provide computers allthose human abilities of   understanding the feelings of others by just recognizingtheir facial expressions, and the tone in which they speak so that these machineswould interact with human beings very easily. It could understand your feelingseven with the touch of the mouse .For example if you are really tensed and youwant to call your friend, this technology automatically understands the urgencyand call your friend who is working in your office or someone who is very closeto you. In short its objective is to provide sensional and perceptual powers tomachines to interact with humans and help the in all situations. Hence computercould act as intimate partners to humans.II.

WORKINGPROCEDURE            This technology works with the combination of both software and hardwarecomponents. Central system unit and the data acquisition unit act as thehardware component. Microcontroller acts as the heart for this technology.

A Bluetoothtechnology is used for connecting both hardware and those software units. Wecould use this type of technology in all working places to understand the emotionshumans and to record them .It generally consists of the following units·       data acquisition unit·       Central system unit·       The software unitDATA ACQUISITION UNIT             It is otherwisecalled as mobile measuring unit.The main objective is to get the physiological informationfrom the sensors and transfer it to central system unit. This is done forprocessing purposes and for verification too. A  Bluetooth is integrated with the DAU is usedto send the data to the central system. Both CSU and DAU contains their own pincodes and id numbers for authentication purposes.

The components that are usedare five-key keyboard, beeper and LCD for displaying purposes. The voice is transferredby using a headset.CENTRALSYSTEM UNIT             Thenext component being used is the CSU. It contains a codec and a Bluetooth module.codec refers to those voice transmitted information.

This part is connected toour computers by using a USB cable or a parallel cable. The microcontrollerwhich is present in it handles the UART transmission.
