Dear Dragan,

Did you read this study ?

Article The effect of cell phone use on postural balance and mobilit...

Another way, some people working on the posture say that the mobile also causes electromagnetic pollution which degrades the posture and induced musculoskeletal pain.

Hope this can help you

Dear Emmanuelle,

Thank you for this interesting article. We will take that for better understanding of our problem.

We allredy have some nice results indicating same conclusion.

Best regards,

Dragan

Dear Dragan Marinkovic !

In my opinion, the task is not difficult. Factors - different phone models with and without headsets, including no phone at all. The results of their influence are various parameters of posture stability. Training sample-observations are designed in such a way as an MS Excel file that each observation corresponds to one row, and the columns reflect the factors and results of their influence.

An example of a full study on this technology is here:

Technical Report Ask-analysis of the impact of the space environment on seism...

There are tools.

As a method of the research we used Automated system-cognitive analysis (ASC-analysis), which is a new innovative method of artificial intelligence: it also has its own software tool – an intelligent system called "Eidos" (open source software) [1, 2, 3].

The Eidos-X++ system differs from other artificial intelligence systems in the following parameters:

- was developed in a universal setting, independent of the subject area. Therefore, it is universal and can be applied in many subject areas (http://lc.kubagro.ru/aidos/index.htm);

- is in full open free access (http://lc.kubagro.ru/aidos/_Aidos-X.htm), and with the relevant source texts (http://lc.kubagro.ru/__AIDOS-X.txt);

- is one of the first domestic systems of artificial intelligence of the personal level, i.e. it does not take special training in the field of technologies of artificial intelligence from the user (there is an act of introduction of system "Eidos" of 1987) (http://lc.kubagro.ru/aidos/aidos02/PR-4.htm);

- provides stable identification in a comparable form of strengh and direction of cause-effect relationships in incomplete noisy interdependent (nonlinear) data of very large dimension of numerical and non-numerical nature, measured in different types of scales (nominal, ordinal and numerical) and in different units of measurement (i.e. does not impose strict requirements to the data that can not be performed, and processes the data that is);

- contains a large number of local (supplied with the installation) and cloud educational and scientific applications (currently 31 and 200, respectively) (http://lc.kubagro.ru/aidos/Presentation_Aidos-online.pdf);

- provides multilingual interface support in 44 languages. Language databases are included in the installation and can be replenished automatically;

- supports on-line environment of knowledge accumulation and is widely used all over the world (http://aidos.byethost5.com/map5.php);

- the most time-consuming computationally, the operations of the synthesis models and implements recognition by using graphic processing unit (GPU) that some tasks can only support up to the solution of these tasks is several thousand times that really provides intelligent processing of big data, big information and big knowledge;

- provides transformation of the initial empirical data into information, and its knowledge and solution using this knowledge of classification problems, decision support and research of the subject area by studying its system-cognitive model, generating a very large number of tabular and graphical output forms (development of cognitive graphics), many of which have no analogues in other systems (examples of forms can be found in: http://lc.kubagro.ru/aidos/aidos18_LLS/aidos18_LLS.pdf);

- well imitates the human style of thinking: gives the results of the analysis, understandable to experts on the basis of their experience, intuition and professional competence.

Using mobile phones with smartphones for many hours a day can cause postural defects. In addition, many young people already have vision defects caused by using smartphones for too long. Some children and adolescents have already become addicted to using smartphones. In some countries, there are already addiction clinics for people addicted to the use of smartphones.

Best wishes.

Thnak you Dariusz...

and what you thinking on longitudinal monitoring of large group of participates via mobile app and using of data for science?

Dragan

Dear Dragan Marinkovic,

Unfortunately, research shows that the problem is getting worse. Excessive use of smartphones by children and adolescents causes visual impairments, a reduction in the time spent on physical activity, and can also cause postural defects due to the constant bowing of the head over the smartphone. There are also other negative effects, such as an increase in the number of traffic accidents, i.e. when young people, looking at their smartphones, enter the street without paying attention to oncoming cars or other vehicles. Such accidents can lead to death or disability.

Greetings,

Dariusz Prokopowicz
