BLUE EYES TECHNOLOGY
![Page 2: Blue eyes](https://reader033.fdocuments.net/reader033/viewer/2022061213/54973429b479597c678b458d/html5/thumbnails/2.jpg)
BLUE EYES is a technology, which aims at creating computational machines that have perceptual and sensory abilities like those of human beings.
The basic idea behind this technology is to give computer human power..
It provides technical means for monitoring and recording human-operator’s physiological condition.

Blue eye is a personal area network. It is intended to be the complex solution
for monitoring and recording the operator’s conscious brain involvement as well as his physiological condition.
It can be implemented for avoiding disasters caused by human errors.

WHAT IS BLUE EYES NOT?
• Doesn’t predict nor interfere with operator’s thoughts
• Cannot force directly the operator to work

HOW ARE BLUE AND EYES ARE RELATED
As the idea is to monitor and record operator’s basic physiological parameters, the most important physiological activity is the movement of eyes.
For a computer to sense the eye movement, wiring between operator and the system is required. But, this is a serious limitation of the operator’s mobility and disables his operations in large control rooms.
So utilization of wireless technology becomes essential which can be implemented through blue tooth technology

Connection manager module
Connection Manager’s main task is to perform Bluetooth communication.
Connection Manager authorizes operators,
manages their sessions, demultiplexes and buffers raw physiological data.

Data analyzer module
The module performs the analysis of the raw sensor data in order to obtain information about the operator’s physiological condition.
Alarm Dispatcher Module is a very important part of the Data Analysis module. It registers for the results of the data analysis, checks them with regard to the user-defined alarm conditions and launches appropriate actions when needed

Conclusion
The wireless link between the sensors worn by the operator and the supervising system makes it possible to improve overall reliability, safety and assures proper quality of system performance.
These new possibilities can cover areas such as industry, transportation, military command centers or operation theaters
