3. GRAPPLE - Public Event Eindhoven NL Virtual Reality (VR) 3D visualizations – 3D environment with 3D objects – Objects may have behaviors – User can interact with objects – User can navigate through the space January 22, 2011 Slide 3

4. GRAPPLE - Public Event Eindhoven NL Desktop Virtual Reality Example January 22, 2011 Slide 4

5. GRAPPLE - Public Event Eindhoven NL Virtual Reality for Learning Added value for learning – 3D visualization may help understanding complex material – The physical counterpart may not be available, too dangerous, or too expensive – To simulate social environments and practice social skills – Much more appealing and motivating than classical learning material January 22, 2011 Slide 5

21. GRAPPLE - Public Event Eindhoven NL Evaluation Results – Learning – 51 master students CS Most participants had no or very little experience with VR January 22, 2011 Slide 21

22. GRAPPLE - Public Event Eindhoven NL Evaluation Results –Learning (2) – Positive feedback Appreciation of VR as learning aid Appreciation for combination of hypertext and VR – Negative feedback Problems with navigating, using VR controls Separation between hypertext and VR part Lack of information/feedback on what happens – Recommendations Better synchronization between hypertext and VR Complete integration of hypertext into VR January 22, 2011 Slide 22
