- PublikationExploring the role of learning activity when learning with video and virtual reality: a mixed methods study with airport security officers(18.01.2021) Kaufmann, Kaspar; Schwaninger, Adrian; Wyssenbach, Thomas; Institute Humans in Complex Systems, School of Applied PsychologyThe present study explored how media (video vs. virtual reality) and learning activity (passive vs. interactive) affect airport security screeners’ learning experiences by applying a 2 x 2 factorial between-subjects design. A mixed methods approach was employed to assess the screeners’ (n = 26) learning, cognitive load, intrinsic motivation, and technology acceptance. Results showed that videos led to slightly higher learning outcomes than virtual reality. While screeners believed interactivity to enhance learning, no main effect was discovered. This result may have been influenced by increased cognitive load experienced by the screeners through interactivity. Intrinsic motivation was significantly higher for screeners learning with interactive video, passive virtual reality, and interactive virtual reality compared to passive video. Regarding technology acceptance, screeners perceived virtual reality and interactivity to be more useful than video and passivity, respectively. Overall, this study offers insight into the potentials of multimedia for learning in a practical setting.11 - Studentische Arbeit
- PublikationValidation of Driving Simulation in a Virtual Reality Setting: The Effects of Age, Sex and Simulation Technology on Driving Behavior(Springer, 03.04.2020) Christ, Oliver; Kaufmann, Kaspar; Wehrli, Simon; Mistretta, Emanuel; Arisona, Stefan; Wyssenbach, Thomas; Schubiger, Simon; Tareq, Ahram; Taiar, Redha; Gremeaux-Bader, Vincent; Aminian, Kamiar [in: Human Interaction, Emerging Technologies and Future Applications II. Proceedings of the 2nd International Conference on Human Interaction and Emerging Technologies: Future Applications (IHIET – AI 2020), April 23-25, 2020, Lausanne, Switzerland]Rapid progress in virtual reality technology empowers immersive and naturalistic driving simulations also for low budget. The technology enables researcher with the means to test different variables in road traffic riskless and reproducible. In real traffic scenarios, differences in driving behavior and safety related-perception can be observed. The object of our study was to develop a low-budget driving simulation environment and to enable a riskless testing of future traffic scenarios.04B - Beitrag Konferenzschrift

- PublikationSocial Robots: Development and Evaluation of a Human-Centered Application Scenario(Springer Nature, 2019) Schulze, Hartmut; Kaufmann, Kaspar; Ziakas, Eleni; Catanzariti, Marco; Stoppa, Giancarlo; Burkhard, Roger; Tanner, Alexandra; Ahram, Tareq; Taiar, Redha; Colson, Serge; Choplin, Arnaud [in: Human Interaction and Emerging Technologies. IHIET 2019]This study aimed to develop and evaluate an application scenario for the use of a social robot, following a human-centered design approach. The social robot, which assisted the reception desk staff of a hotel by answering simple, repetitive and time-consuming questions (e.g. parking information, directions), was perceived predominantly positive by employees and guests of the hotel. However, the results suggested that to effectively reduce the employees’ workload and to provide a reliable source of information for the guest, the robot had to work on a high level of autonomy and technological stability. Additionally, the use of a social robot may estrange guests and employees alike, as they prefer human interaction or are fearful of job loss, respectively. An early inclusion of the employees in the design process has shown to reduce fears and increase acceptance towards the social robot and its integration into the workforce.04B - Beitrag Konferenzschrift
- PublikationFussgängererkennung im virtuellen Raum(14.09.2017) Kaufmann, KasparFortschritte im Bereich der virtuellen Realität lassen heutzutage das Simulieren von reali-tätsnahen und immersiven Verkehrsszenarien zu. Für die Fussgängersicherheit bedeutet dies eine gefahrenlose und kostengünstige Methode, um die Fussgängererkennung im Strassen-verkehr zu untersuchen. Dazu wurde im Rahmen dieser Arbeit ein Fahrsimulator gestaltet und für die Zwecke einer Reaktionszeitstudie eigesetzt. Die Studie überprüfte die Annahmen, dass ein VR-Display einem herkömmlichen Monitor bei der Fussgängererkennung überlegen ist und dass Fussgänger am Tag schneller als in der Nacht erkannt werden. Für die Daten-auswertung wurden 32 Probanden berücksichtigt. Die Ergebnisse lassen einer Verifizierung beider Annahmen zu. Daraus können für den verwendeten Verkehrssimulator positive Schlüsse gezogen werden. Die Implikationen für die VR-Technologie sind trotz hoffungsvoller Studienresultate weniger eindeutig. Insbesondere die Simulatorkrankheit scheint weiterhin eine Einschränkung darzustellen.11 - Studentische Arbeit
