HRDs 4
Gigapixel Image 5 Gigapixel Project - www.gigapxl.org
Advantages HRDs 6 HRDs fit human capabilities: visual angle, visual acuity, superior immersion Virtual navigation enhance real one (not a replacement) direct interaction, faster Real overview & context, detail on demand, interactive wall Increased real estate for e.g. spatial information management, creative brainstorming, interactive whiteboard
Challenges & Chances 7 Small focal & large peripheral areas Varying distances (need for lightweight, small, wireless, ergonomic input devices) User / group behavior Multi user / multiple devices Collaborative Environment
Input Devices 8
Input Devices 9 Design Characteristics: [Vogel, Balakrishnan 05] Accuracy Acquisition Speed Interaction Speed Ergonomic Use Smooth Transition Between Interaction Distances
Laser Pointer Tracking 10 Already used as pointing device, intuitive and easy to use (Almost) distance independent Client-Server Architecture Highly scalable Standard, low-cost hardware Fast & easy calibration Various settings (front/back, centred/sloped, upright/horizontal)
Camera calibration 11
PowerWall camera settings 12
Further tracking tools 13 ART passive infrared optical tracking system 5DT Data Glove, 14 sensors (flexure & abduction)

UI Concepts & Paradigms 17
UI Concepts & Paradigms 18 Large-display usability issues: [Robertson et al. 05] Losing the cursor Bezel problems Distal information access problems Window management problems Task management problems Configuration problems
Information organization? 19
More space more information? 20
ZOIL Paradigm 21 Zoomable Object-oriented Information Landscape No desktop information landscape No windows zoomable objects No menus, scrollbars direct manipulation with zooming and Primary panningvisual access on large information space Spatial metaphor instead of abstract hierarchies New interface paradigm inspired by Jef Raskin s ZoomWorld with the integration of HyperGrid, ZUIScat and other ZUI components.
ZOIL Paradigm 22
Next steps 23 Enhance Laser Tracking (industry cameras, infrared, filter, gestures, OCR, device combinations) Integrate ART Tracking System & 5DT Data Glove, PDA Interaction Evolve adequate interaction techniques (gestures, widgets, ) Evaluate conventional & novel input devices Develop general interaction framework Apply ZOIL Paradigm on PowerWall for specific use case
