- KonferenzbeitragComparative Evaluation of Gesture and Touch Input for Medical Software(Mensch und Computer 2015 – Proceedings, 2015) Saalfeld, Patrick; Mewes, André; Luz, Maria; Preim, Bernhard; Hansen, ChristianThe interaction with medical software during interventions challenges physicians due to the limited space and the necessary sterility. Current input modalities such as touch screen control present a direct, natural interaction which addresses usability aspects but do not consider these challenges. A promising input modality is freehand gesture interaction, which allows sterile input and a possibly larger interaction space. This work compares gesture and touch input regarding task duration to perform typical intervention tasks and intuitiveness. A user study with ten medical students shows mostly significantly better results for touch screen interaction. Despite the advantages of freehand gestures, it is debatable whether these can compensate the better efficiency and usability results of touch screen interaction in the operating room.
- 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.
