Stress Detection using Galvanic Skin Response: An Android Application

Abstract

Stress is one of the factors that affect human health in many aspects. It is considered as one of the culprits in increasing the risk of getting sick that could probably lead to critical physical or mental illnesses. Stress can be experienced everywhere and in different circumstances. Hence, stress should be controlled and managed by monitoring its progress or regress. Physiological information can be used to determine stress levels. One of these is the Galvanic Skin Response (GSR) that utilizes skin conductance which is known to be directly involved in the emotional behavioural regulation in humans. In this study, a method on how to determine stress when a person is engaged in mobile communication is proposed. An Android application was developed that is capable of determining the stress level of a person while doing SMS composition. GSR data were utilized and the performance of the proposed method was found of no significant difference with a commercially available device. Factors like phone size and period of texting was investigated and were found out that these only contribute an extremely low level of stress. The developed App could be used to determine stress levels especially if emotional conversations are considered.

“…Perseverative Cognition What therefore sustains physiological activity before or after a stressor? The development of a theory of this mediator has been hindered by the prevailing stress theories' absence of the extended activation element [2]. Although several theories have included the prolonged activation element, they have not specifically proposed a cognitive mechanism that genuinely extends activation in response to stresses or how they perceive them.…”

“…It is generally established that pre-surgery stress negatively impacts a person's ability to cope and maintain their physical and psychological health. Most of the earlier research has been on the use of physiological markers for stress detection [2]. Many studies have employed various physiological signals, such as the galvanic skin response (GSR) or Electro Dermal Activity (EDA), electrocardiogram (ECG), electrooculography (EOG), electromyogram (EMG), and multiple physiological signals to identify stress in binary (stress / no stress) or multi-Level (e.g., low, moderate, and high) forms.…”

“…These studies made the case that a person's stress reaction cannot be fully assessed by using a single marker [4] [3]. On the other hand, a few earlier research relied on advantages such as lower computing costs, better real-time system conditions, and the use of conventional wearable device data to identify stress levels using only one signal-typically the ECG or GSR [2]. The measurement of the constant changes in the electrical properties (conductance) of the skin brought on by changes in the body's sweating activity is called GSR or EDA.…”

“…As a result, skin conductance increases and skin resistance decreases. Human sympathetic nerve system (SNS) reactions, which are directly related to the control of emotional behavior in humans, are measured in this instance [2]. One of the most used methods for identifying both short and long-term stress is the electrocardiogram (ECG) [4].…”
