Abstract

In the present research, attention was turned to the usability of the smartphone electronic device, which is an object that has become essential in the lives of thousands of people, being used daily for whatever purpose and among so many features that benefit the device. Phone and appeals to users, but can become a causal factor for user pathologies. To understand signs and symptoms due to poor musculoskeletal posture of the user, the study sought first to survey the bad habits adopted by mobile phone users in the upper Sertão Alagoano / Baiano region. Thus, we made use of ergonomic analysis to know the main costly health habits of mobile device users. From this analysis, methods can be developed that provide a good performance in the activities being performed, without compromising the user's health, thus ensuring their well-being. Therefore, based on the results it was possible to realize that most users adopt the bad habit of using the phone, according to the postures. Regarding the time of use is essential, because the longer you have access to technology, the more likely you are to have both dependence and risk of pathologies. Thus, the main results were related to the time of use, for more than eight years, the dependence of the cell phone and the certain way of using the cell phone according to the adopted posture.
