    The Influence of Participants’ Personality on Quantitative and Qualitative Metrics in Usability Testing
    (Mensch und Computer 2019 - Tagungsband, 2019) Schmidt, Thomas; Wittmann, Vera; Wolff, Christian
    We present the results of a usability study with 35 participants investigating the influence of personality on various metrics used in usability engineering. We conduct a task based usability test with a website integrating tasks of various difficulty and also measure performance metrics like task completion rate and time on task. We also use standard questionnaire based usability metrics like the System Usability Scale (SUS). Furthermore, we gather qualitative data via open-ended questions and count the number of words as well as the mentions of positive and negative aspects. We measure personality using the well-known big five model, also often referred to as OCEAN model (openness, conscientiousness, extraversion, agreeableness, neuroticism) and three basic needs (need for influence and power, need for recognition and performance, need for security and tranquility). We analyze the relationship between personality and usability metrics via correlations and regression models. We identify multiple significant results and show that in our study the personality correlated with some of the usability metrics we inspected. Extraversion and the need for influence and power show the most and strongest correlations. Furthermore, we also show that regression models based on personality traits can explain up to 37% of the variance in usability metrics. The results have implications for the improvement of the selection process of usability test participants as well as for the interpretation of test results. We discuss these implications and give an outlook on further research in this area.

    Safety-Critical Personality Aspects in Human-Machine Teams of Aviation
    (i-com: Vol. 15, No. 3, 2016) Eschen, Solveig C. S.; Keye-Ehing, Doris; Gayraud, Katja
    Working safely and successfully in highly automated human-machine interfaces of future aviation is not only a matter of performance, but also of personality. This study examines which personality aspects correlate with safety-critical performance in human-machine teams. The research tools HTQ (Hybrid Team Questionnaire) and HINT (Hybrid Interaction Scenario) were combined for a comprehensive exploratory study. The HTQ includes personality scales measuring broad factors of personality (Big Five) as well as more specific scales and was added with objective personality assessments to measure risk taking. The simulation tool HINT simulates relevant processes in future human-machine team interaction in aviation. In a study with 156 applicants for aviation careers, safety-critical relations of some facets of general personality as well as risk taking were found. Especially personality aspects concerning disinhibiting, spontaneous behaviour and sensation seeking show correlations with poorer performance in the HINT simulation.
