BLUE EYE Prepared by: P. Monalisha S/06/

Blue eye technology : 

Blue eye technology ( blue eyes – Human operator monitoring system ) BY

Agenda : 

Agenda Motivation What is BlueEye technology ? What is BlueEyes ? System designing System overview DAU CSU Data security IBM research Conclusion

Motivation : 

Motivation Human error - a frequent reason of catastrophes and ecological disasters Lack of complex solution exploiting wireless link technology, database systems and AI algorithms weariness oversight Monitoring of consciousbrain involvement Capable sensors available

What is blue eye technology ? : 

What is blue eye technology ? The BLUE EYES technology aims at creating computational machines that have perceptual and sensory ability like those of human beings.

How can we make computers “see” and “feel” ? : 

How can we make computers “see” and “feel” ? Blue eyes uses sensing technology to identify a user’s actions and to extract key information. Information is then analyzed to determine the user’s physical ,emotional ,or informational state.

What is BlueEyes ? : 

What is BlueEyes ? The complex solution for human-operator monitoring: Visual attention monitoring Physiological condition Operator’s position detection Wireless data acquisition using bluetooth Real time user defined alarm triggering Recorded data playback

What is BlueEyes not? : 

Doesn’t predict nor interfere with operator’s thoughts Cannot force directly the operator to work What is BlueEyes not?

IBM research : 

IBM research BLUE EYE – EMOTIONAL MOUSE sensors in the mouse ,sense the physiological attributes which are correlated to emotions using correlation model -by simply touching the mouse ,the computer will be able to determine a person’s emotional state. BLUE EYE enabled TELEVISION – could become active when the user makes an eye contact.

Physiological foundations : 

Physiological foundations Preconscious brain manages the knowledge logical reasoning makes decisions alogical „automatic” Conscious brain Human brain

Conscious brain - operation modes : 

Conscious brain - operation modes Exploratory mode Planning mode

The eye movement sensor : 

The eye movement sensor Off-shelf eye movement sensor – Jazz multisensor Supplies raw digital data regarding Eye position Level of blood oxygenation Acceleration along horizontal and vertical axes Ambient light intensity

Eye movements : 

Eye movements Saccade - a rapid eye jump to a new location assigned by the conscious attention process. Saccades presence  Exploratory mode Central vision andthe conscious brain

Jazz multisensor :

Design objectives : 

A reliable real-time buffering, processing and recording A clear visualization interface Mechanisms for creating custom data analyzers To ensure a possibility of distributing the processing among a number of computers Design objectives A mobile data acquisition device

Implementation and engineering considerations : 

Implementation and engineering considerations -THREE groups of users OPERATOR -a person whose physiological parameters are supervised - authorization in the system - receiving alerts SUPERVISOR – a person responsible for analyzing operator’s condition and performance. SYSTEM ADMINISTRATORS- maintains the system deliver tools for adding - new operator’s to the database - defining alarm conditions - configuring logging tools - creating new analyzer modules

Designing : 

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 )
