Focus and Context Awareness Visualization Techniques for 3D Modelling Tasks Using Multi-layered Displays

Creating complex 3D polygonal models using existing modelling software can be challenging. Most 3D Modelling software have been designed for 2D displays and lack support for effective perception of depth ordering. Studies have shown that users of these types of software encounter a range of focus and context awareness problems while performing their 3D modelling tasks. We have previously developed a number of visualization and interaction techniques to better support focus and context awareness using multi-layered displays. A user study of these techniques has demonstrated that they need further improvements. Here, we present three modified visualization techniques, which as shown by a user study, improve the effectiveness of these previous alternatives.
