Слайд 15

LEARNING & WORKING IN VWS • Provision of different communication channels (verbal & non-verbal) • Activity-based interactions support the motivation and autonomy of the users • Increased social awareness • Feeling of presence in the virtual environment • Awareness of other avatars, the environment • Belonging to a social community which creates a virtual social space • Facilitated collaboration through different tools • Visualizations and simulations of learning content via 2d and 3d artifacts • Personal motivation through active participation and co-creation of the world

RESEARCH QUESTIONS • (a) advantages and disadvantages compared to other visualisation methods such as 2D map based visualisations • (b) would users like to walk through visualisations • (c) does the immersive character change the user’s perception of the visualisation • (d) would users benefit from the collaborative multi- user capabilities.


Слайд 24

SUMMARY • Visualisation for discovery and understanding • 3D Visualisations can support other forms of emotions, understanding, learning, and analysing • VR, new forms of haptic interfaces, and 3D Web is coming • 3D worlds support interactive, collaborative, and immersive simulations • Other insights and new forms of analysis compared to 2D • Web-browser data visualisations (e.g. Unity)


Слайд 25

SUMMARY • Identify good & reasonable visualisation opportunities • Still complicated & more expensive compared to 2D • Target group? • VR, new forms of haptic interfaces, and 3D Web is coming -> we still wait • Should provide new insights and not new challenges
