Blue Eye Technology

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 presence, and starts interacting with you .You ask the computer to dial to your home urgently. It realizes the urgency of the situation through the mouse, dials your mother at home, and establishes a connection.

Human cognition depends on highly developed abilities to perceive, integrate, and interpret visual, auditory, and touch information. Without any doubt, computers would be much more powerful if they had even a small fraction of the perceptual ability of animals or humans. These are to be brought in a computer through the help of small systems built for each function. Researchers are attempting to add more capabilities to computers that will allow them to interact like humans, recognize human presents, talk, listen, or even guess their feelings.

     What Is Blue Eyes Technology?

Aims at creating computational machines that have perceptual and sensory ability. Use camera and microphone to identify user actions and emotions Blue Eyes – Bluetooth technology and the movements of the eyes. Bluetooth provides reliable wireless communication. As 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.

 For example, a Blue Eyes-enabled television could become active when the user makes eye contact, at point the user could then tell the television to "turn on".

WHY BLUE EYES?

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

· To built a machine that can understand your emotions
· A pc that can listen, talk or scream

· Verify your identity, feels your presence and interact with you.

 1)      Objectives of Blue eyes: Design smarter devices.

                                 Create devices with emotional intelligence.

                                 Create computational devices with perceptual abilities.

Note that the idea of giving computers personality or, more accurately, emotional intelligence may seem creepy, but technologists say such machines would offer important advantages.

 Blue eyes and its basic structures

The BLUE EYES technology aims at creating computational machines that have perceptual and sensory ability like those of human beings. It uses non-obtrusige sensing method, employing most modern video cameras and microphones to identify the user`s actions through the use of imparted sensory abilities. The machine can understand what a user wants, where he is looking at, and even realize his physical or emotional states.

The process of making emotional computers with sensing abilities is known as Affective Computing. The steps used in this are:

·         Giving sensing abilities.

·         Detecting human emotions/ Affect Detection.

·         Respond properly and appropriately.

Giving sensing abilities

Machines are provided with the equivalent of the eyes, ears, and other sensory organs that humans use to recognize and express emotion. To that end, a variety of mechanisms are being explored including voice-recognition software that can discern not only what is being said but the tone in which it is said; high resolution cameras that can track subtle facial expressions, eye movements, and hand gestures; and biometric sensors that can measure body temperature, blood pressure, muscle tension, and other physiological signals associated with emotion.

Detecting human emotions

The computers have to detect even the minor variations of our moods. Say a person may hit the keyboard swiftly or fast either in the happy mood or in the angry mood. In the third step the computers have to react in accordance with the emotional states. This is done with the help of intelligent input devices like Emotion Mouse (to track emotions of user) through which the computer takes the inputs. Artificial Intelligent Speech Recognition and Simple User Interest Tracker (SUITOR) are used to know, understand and interpret the speech and interest of the user at that instance of time.

 

 

The four things considered for implementation of Affective Computing are:

•      Emotion Mouse.

•      Manual Aand Gaze Input Cascaded (MAGIC) Pointing.

•      Artificial Intelligent Speech Recognition.

•      The Simple User Interest Tracker (SUITOR).

A.       The Eye Movement Sensor Designing

       A personal area network for linking all the operators and the supervising system.

        Two major units

        · DAU (Data Acquisition Unit)

        · CSU (Central System Unit)

 1)       DAU (Data Acquisition unit): Data Acquisition Unit is a mobile part of the Blue Eyes system. Its main task is to fetch the physiological data from the sensor and to send it to the central system to be processed. To accomplish the task the device must manage wireless Bluetooth connections (connection establishment, authentication and termination). Personal ID cards and PIN codes provide operator's authorization. Communication with the operator is carried on using a simple 5-key keyboard, a small LCD display and a beeper. When an exceptional situation is detected the device uses them to notify the operator. Voice data is transferred using a small headset, interfaced to the DAU with standard mini-jack plugs. The Data Acquisition Unit comprises several hardware modules:

 

· Atmel 89C52 microcontroller - system core

· Bluetooth module (based on ROK101008)

· HD44780 - small LCD display

· 24C16 - I2C EEPROM (on a removable ID card)

· MC145483 - 13bit PCM codec

· Jazz Multisensor interface 

· beeper and LED indicators  

· 6 AA batteries and voltage level monito

 

1)       CSU (Central System Unit): For wireless network connection, CSU is the next main important thing in the Blue Eyes technology. The CSU mostly consists of voice information transmission and a wireless Bluetooth device. This CSU is connected to a computer using USB wire, parallel and serial cable wire. The socket named mini jack is used for accessing the audio data. The program that contains the operators personal ID is communicating to the personal computer through the serial and power ports. Central System Unit hardware is the second peer of the wireless connection. The box contains a Bluetooth module (based on ROK101008) and a PCM codec for voice data transmission. The module is interfaced to a PC using a parallel, serial and USB cable. The audio data is accessible through standard mini-jack sockets to program operator's personal ID cards we developed a simple programming device. The programmer is interfaced to a PC using serial and PS/2 (power source) ports. Inside, there is Atmel 89C2051 microcontroller, which handles UART transmission and I2C EEPROM (ID card) programming. CSU – Component are:

 

· Connection Manager – main task to perform low-level blue tooth communication
