- ZeitschriftenartikelFoot Interaction Concepts to Support Radiological Interventions(i-com: Vol. 17, No. 1, 2018) Hatscher, Benjamin; Luz, Maria; Hansen, ChristianDuring neuroradiological interventions, physicians need to interact with medical image data, which cannot be done while the hands are occupied. We propose foot input concepts with one degree of freedom, which matches a common interaction task in the operating room. We conducted a study to compare our concepts in regards to task completion time, subjective workload and user experience. Relative input performed significantly better than absolute or rate-based input. Our findings may enable more effective computer interactions in the operating room and similar domains where the hands are not available.
- TextdokumentHaptic Journey: The integration of gesture-controls and mid-air haptic feedback into ticket machines to foster better hygiene in public spaces(Mensch und Computer 2023 - Workshopband, 2023) Ambacher, Julian; Fischer, Luci; Gaurav, Anand Bihari; Pietruschka, Maria; Spreng, Leoni; Wilkes, Jasmin; Zimmermann, Theresa; Peintner, Jakob; Riener, AndreasSince the outbreak of Covid-19, hygiene is a major issue, especially in public spaces. One example are public ticket vending machines (TVMs). With their contactless interaction, gesture-controlled interfaces offer a valid alternative to touchscreens and haptic buttons, which are still widely used in current machines. To explore the impact of mid-air haptic feedback combined with gesture-control we conducted interviews, an online survey and a usability study to measure user experience and user satisfaction. Our results show that hygiene plays a major role in public spaces. Furthermore, gesture-control combined with mid-air haptic feedback has the potential to provide more hygienic interaction that enhances user experience and usability compared to traditional TVMs.
