Key result
Stress detection using biosignals based on image processing techniques via webcam is a cheap and easy method to implement, though accuracy and environmental influences remain challenging.
Why the study?
Stress is an increasing problem, and because some individuals are unaware of their stress, a noninvasive, easy, and convenient method is needed for early detection to prevent worsening conditions.
Can stress be detected using biosignals based on image processing techniques?
Can stress be detected using biosignals based on image processing techniques?
Image processing techniques using webcams offer a noninvasive, cheap, and easy method for daily life stress detection, though accuracy improvements are needed.
Accuracy challenges limit clinical adoption of webcam stress detection; leaves open validation and refinement in prospective studies.
Stress is a problem in human life today. The pandemic caused by COVID-19 has also caused increased stress. Some people are aware of the stress they are experiencing and can control it, but some are unaware. Subsequently, it is vital to identify it early to anticipate worsening the condition. A noninvasive, easy, and convenient method is needed to predict daily life stress. One widely developed noninvasive stress detection method is the image processing technique. This technique uses images captured by cameras. Various image processing techniques are applied, i.e., extracting temperature, biosignal, and respiration parameters. This study investigated research on stress detection using biosignals based on image processing techniques. This research found that stress detection can be done using a webcam, a cheap and easy method to implement. Several limitations, such as accuracy and minimizing environmental influences, are still challenging to improve.
