| Abstract: | Ambulatory detection of stress is important in preventing chronic diseases. In this study, we created a multi-sensor processing framework and investigated how the stress-related features vary between laboratory and daily-life stressors. The stress responses were measured with the wearable Empatica E4, containing photoplethysmography (PPG), skin conductance (SC) and skin temperature (ST). The laboratory measurement consisted of a public speaking task, a mental arithmetic task and the Stroop Colour Word Test. Stress in daily-life was measured for two weeks with Ecological Momentary Assessment. Linear models for the laboratory and daily-life stressor were designed for each participant based on the stress-related features and self-reports. The results point into the direction that the stress associated features are different between laboratory and daily-life settings and individuals. This suggests the need for individualized models for stress detection and for viewing the information from laboratory and daily-life measurements as complementary. Next to that, a framework was created for stress detection with a multi-sensor approach, which contained pre-processing steps as filtering and quality indicators to assess the quality of the signals. |
