Fuzzy logic method-based stress detector with blood pressure and body temperature parameters

“…DASS 42 is a questionnaire with 42 questions, consisting of 3 emotional scales: depression, anxiety, and stress with levels as shown in Table 5; normal, mild, moderate, severe, and very severe [31]. The DASS 42 scale can be classified into 3 [32], which are the depression scale (questions number 3,5,10,13,16,17,21,24,26,31,34,37,38,42), the anxiety scale (questions number 2, 4, 7, 9, 15, 19, 20, 23, 25, 28, 30, 36, 40, 41.3), and the stress scale (questions number 1,6,8,11,12,14,18,22,27,29,32,33,35,39).…”

“…The fuzzy logic method is a method that can process variables that are fuzzy or cannot be described with certainty [16]. The advantages of the fuzzy logic method are that it is easy to understand because it uses the basis of set theory, is very flexible, meaning that it is able to adapt to changes and uncertainties that accompany problems, has tolerance for inaccurate data, is able to model very complex nonlinear functions [17], can build and apply the experiences of experts directly without having to go through a training process which is often known as the fuzzy expert system, can work with conventional control techniques [18]- [20]. Fuzzy logic is also based on everyday language, so it is easy to understand [21].…”
