    AnswerTruthDetector: a combined cognitive load approach for separating truthful from deceptive answers in computer-administered questionnaires
    (i-com: Vol. 22, No. 3, 2023) Maleck, Moritz; Gross, Tom
    In human-computer interaction, much empirical research exists. Online questionnaires increasingly play an important role. Here the quality of the results depend strongly on the quality of the given answers, and it is essential to distinguish truthful from deceptive answers. There exist elegant single modalities for deception detection in the literature, such as mouse tracking and eye tracking (in this paper, respectively, measuring the pupil diameter). Yet, no combination of these two modalities is available. This paper presents a combined approach of two cognitive-load-based lie detection approaches. We address study administrators who conduct questionnaires in the HCI, wanting to improve the validity of questionnaires.

    CoLoTiMa: A Cognitive-Load Based Time Management Tool
    (Proceedings of Mensch und Computer 2024, 2024) Maleck, Moritz; Gross, Tom
    Time management has the potential to maintain the learning and working productivity. Prominent techniques—such as Pomodoro—typically suggest to alternate productive periods and breaks. They are mostly time-based and lack adaptability to individual preferences and cognitive workloads. In the context of learning, this leads to suboptimal learning experiences, with rigid time structures hindering productivity and reducing efficiency. We introduce CoLoTiMa, a novel approach that dynamically adjusts learning period durations. It integrates real-time cognitive-load measurements and user self-assessment to tailor learning experiences. Through the use of eye-tracking, CoLoTiMa optimises the duration of learning blocks in accordance with individual learning preferences and thus fosters personalised and efficient outcomes.
