Blue eyes technology is one of the finest example the development of this digital era. 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.
Blue eyes technology mechanism
The Blue eyes technology aims at creating computational machines that have perceptual and sensory ability like those of human beings. It uses non-obtrusive 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.
Blue eyes system monitors the status of the operator’s visual attention through measurement of sadistic activity. The system checks parameters like heart beat rate and blood oxygenation against abnormal and triggers user defined alarms.
How blue eyes system works ?
1- Mobile measuring device or Data Acquisition Unit (DAU) of Blue Eyes technology:
The DAU used in the Blue Eyes technology is the mobile component of the system. The main function of DAU is to gather the physiological information from sensors and forward to the CSU for processing and verification purposes.
The bluetooth module, which is integrated with the mobile device (DAU), provides a wireless interface between the Central System Unit (CSU) and the user or operator having the sensors. PIN codes and ID cards are assigned to the entire operator’s for authentication purposes. The device uses a five-key keyboard, beeper and LCD display for the interaction with the operators and if, any unwanted situation occurs, the machine uses these devices to inform the operators.
The ‘voice’ information from the user is transferred with the help of a headset, which is interfaced with the Data Acquisition Unit using a mini jack plug. DAU incorporates various hardware modules like system-core Bluetooth section, Atmel 89C52 microcontroller, EEPROM, Beeper, LCD display (HD44780), LED indicator, voltage level monitors and 6 AA batteries.
2- Central system Unit (CSU) of Blue Eyes technology:
CSU is the next squint of wireless-network connection in the Blue Eyes technology. The CSU mainly contains codec (PCM Codec commonly used for voice information transmission) and a wireless blue tooth module. This CSU section is integrated to a personal computer using USB, parallel and serial cable.
The mini-jack socket is used for audio data accessing. The program containing the operators personal ID is amalgamating to the personal computer through the serial and power ports. The micro controller (Atmel- 89C2051) inside the unit handles the I2C EEPROM- programming and UART transmission.
The Blue Eyes Technology and Its Basic Structure:
Blue Eyes technology uses most modern cameras, microphones and advanced non-obtrusive sensing techniques to interact with humans and understand the emotions of human beings. The process of making a computer having sensing and emotional capabilities is known as “Affective Computing”.
The steps involved for designing such type of computers are given below.
Process of giving sensing capacity:
The voice recognition software can perceive not only what is being spoken but also the tone how it is said. High resolution cameras are used for tracking the minute facial expressions, hand gestures and eye movements. Bio metric sensors are used for measuring and analyzing the muscle tension, body temperature, blood pressure and other physiological gesture correlated with emotions.
Detecting human emotions/ Affect Detection:
The Blue Eyes enables the machines to identify these minor emotional variations of human beings even by a single touch on the mouse or key board and the machines started to react with the users according to this emotional level. This is done with the guidance of intelligent devices like “Emotion Mouse Simple User Interest Tracker (SUITOR) and Artificial Intelligent.”
Benefits of the Blue eyes technology:
Blue Eyes system provides technical means for monitoring and recording human operators physiological condition
- Visual attention monitoring (eye motility analysis)
- Physiological condition monitoring (pulse rate, blood oxygenation), operator’s position detection (standing, lying)
- Physiological data, operator’s voice and overall view of the control room recording recorded data playback
Blue Eyes system can be applied in every working environment requiring permanent operator’s attention:
- At power plant control rooms
- Flight control centers
- Professional drivers
