    Influence of augmented reality interaction on a primary task for the medical domain

    Augmented reality can deliver valuable information right where the user needs it. When used to display complex data, interaction is required to access all the information. For general use-cases, hand gestures are the go-to technique to interact in augmented reality contexts. However, in some usecases, the hands are not always available for interaction. For instance, in the operating room, it is likely that the surgeon needs to perform a primary task with the hands simultaneously. This work investigates the influence of interaction tasks using head & hand, head & foot and head & speech on a primary task and the suitability of these input modalities for two kinds of interaction tasks. Results show that interaction techniques used in a multitasking environment should always be evaluated together with a primary task as it might cause user preferences to shift.

    Plantar pressure-based gestures for medical image manipulation
    (Mensch und Computer 2018 - Tagungsband, 2018) Solovjova, Alina; Labsch, Dominic; Hatscher, Benjamin; Fritzsche, Markus; Hansen, Christian
    In this work, we present an interaction concept for manipulating an image viewer only using a pressure sensitive shoe insole. A simple foot gesture set has been created and applied to a prototypical user interface, which enables the changing of slices of medical image data in an image viewer. In a pilot study, the gestures were tested according to the NASA Task Load Index (NASA-TLX). The purpose of this project was to estimate how suitable and user-friendly different foot gestures are in practice. We found that plantar pressure-based gestures are quite intuitive and users quickly become accustomed to using them. However, gestures based on overlapping pressure-sensitive areas might lead to unintended results.
