    Correlation Between Heart Rate, Skin Temperature and Emotional State in Exergames
    (Mensch und Computer 2022 - Tagungsband, 2022) Bruns, Fenja; Wallhoff, Frank
    Computer games have become an established medium, exergames are a special type of game. These are controlled by movement and are designed to improve its users performance. Emotions are an important component during gameplay because they can provide inferences about the user experience. This paper therefore conducts a study to test the correlation of different emotional stages with metrics of heart rate, heart rate variability and skin temperature. This is to validate the feasibility of this data in exergames. To this end, two exergames were played while biosignals were recorded. The discretely measurable data is combined with subjective assessments of the users to identify a correlation to the individually perceived emotion. Statistically significant correlations were found between the physiological characteristics and the affective state of the subjects.

    Non-Contact In-Car Monitoring of Heart Rate: Evaluating the Eulerian Video Magnification Algorithm in a Driving Simulator Study
    (Proceedings of Mensch und Computer 2024, 2024) Renner, Philipp; Gleichauf, Johanna; Winkelmann, Sven
    Monitoring drivers’ health is crucial for saving lives in emergencies and enabling in-car health applications. The state of the art in pulse monitoring is contact-based sensors which impair the driving experience and have to be applied manually before driving. This paper focuses on automated hyper parameter optimizing the Eulerian Video Magnification (EVM) algorithm, which detects heart rates through non-contact facial camera images, for use in driving scenarios. We conducted a user study where 21 participants performed a driving simulation while their heart rates were recorded by a wearable fitness tracker (serving as ground truth) and facial images with an RGB camera. Our findings indicate that, despite using the optuna library for hyper parameter tuning, the Eulerian Video Magnification algorithm is insufficient for accurate pulse detection in a driving simulator environment.
