The viewer of this exhibit canA. Experience novel user interaction concepts specifically designed for mobile devices, focusing on the most common functions like scrolling and changing window level & widthB. Compare these novel approaches with common user interface approaches for mobile devices that have originally been devised for non-medical applications


A. Motivation: Discussion of the increasing need for interactive image visualization on mobile devices, e.g. for emergency image access or for clinical referenceB. Disadvantages of common user interaction approaches: Obscuring image content with fingers, image quality reduction caused by smudged display, decreased usability due to limited screen spaceC. Novel user interaction approachC1. Dedicated protected screen area for image viewing without direct user interactionC2. Interactive multi-touch scout view for fast scrolling (with one finger) and for defining thickness of sliding subvolume maximimum intensity projections (MIP) (with two fingers)C3. Utilization of the built-in motion sensors for a) scrolling (slice-by-slice or cine mode), and b) for changing window level and widthC4. Virtual touchpad area as a general replacement tool for direct touch interactions (e.g. for annotations or measurements)
