Non-intrusive human fatigue assessment

Project aim is to develop platform with complex passive multi-level fatigue monitoring system and workability evaluation system designed in order to provide an integrated service in professional safety and health area.

Human fatigue is the result of prolonged or unusual work manifesting as attention and work capacity reduction for a certain period of time (Čupriks and Knipše, 2006). Statistical data shows that 20% of population is suffering from fatigue, which reduces the work capacity and quality of life. Tiredness is the cause of a slower response, reduced the ability to process information from memory, reduced insight, attention and coordination problems, which, in their turn, can lead to serious problems in the various areas. In patient rehabilitation (recovery) process it is important to ensure a continuous monitoring of the fatigue during day-to-day activities, not only for prevention of the deterioration of health but even for fatal accidents. In Baltic countries every year more than 1000 work injuries associated with fatigue at the workplace occurs. Health problems for athletes in 100% of cases are associated with the overload caused by fatigue. So with fatigue associated economic, health, quality of life affects a large part of the population both in Baltic countries and in the world. Fatigue may be mental, physical, sensory and affective (DeLuca, 2005). But any type of fatigue can be observed from the body reactions. In practice the following releases of fatigue are know: compensated phase, when the individual is offset by increased effort and decompensated phase when fatigue does not even if fatigue symptoms increased effort to somatic illnesses become burn-off syndrome (Christodoulou, 2005). Fatigue evaluation is a complex process, and it is not easy to find out simple methods for it. Until now mainly used for the evaluation of fatigue physiological parameter measured (electroencephalogram (EEG), an electrocardiogram (ECG), eye and jaw muscle movements, leg muscle movements, breathing the) air flow and the respiration rate as well as the oxygen saturation in the blood) under laboratory conditions and is therefore not an individual and is not widely used in daily practice, for an individual user on – line mode. So the objective of project is to create integrated platform for a fatigue and working capacity monitoring and decision-making systems for everyday use with the decision and reasoning in real time across multiple application areas, such as the rehabilitation, sport and workplaces. To achieve the objective, the following activities shall be carried out according the time-line of project: 1. Selection of physiological parameters for assessing the degree of fatigue and working capacity not associated with laboratory tests, as well as the subjective verbally data from questionnaires or test results; 2. Study the fatigue and working capacity evaluation and selection of the components (physical, mental, etc. component); 3. Parameters to be measured and the interrelationship between the components of fatigue and working capacity study; 4. The adoption of the decision determining the degree or extent of methodologies for fatigue and working capacity components at the selected parameters; 5. A study of the total fatigue as system, the resulting system option; 6. The adoption of the decision on a common methodology fatigue and working capacity after graduation of the degree or extent of components; 7. A study on the suitability of different use cases of system under development; 8. Use cases features research, decisions and recommendations of system creation; 9. Decision-making methods, depending on the overall development of recommendations for each of the use cases fatigue estimation. 10. Research and creation of sensor design what may be implemented in wearable device 11. Determination of wireless information system parameters from the sensors for analysis to the device and from the device; 12. Creation of smart phone user interface and software; 13. Parameters and the proposed recommendations of visualization on the smart phone/tablet computer screen. 14. Pilot testing of the system hardware and software and its adjustments. Advancing issues and the allocation between the members of the partners: RTU will be responsible for 2., 3., 4., 5., 6., 9 and 12 place on the list of activities. Lithuanian universities collectively responsible for 1., 2., 3., 7. and 8. positions. Integris will be responsible for the 10, 11 and 13 positions. All partners have responsibility on 14 and in addition, for industrial research systems and the development of the pilot project, which includes the development and marketing of micro schemes type sensor bloc, bracelets, wireless data transmission with the latest in WiFi technology to a smart phone and/or tablet computer.
