Hybrid Interfaces in VEs:
May 6, 2006 2
G. de Haan, “Hybrid Interfaces in VEs: Intent and Interaction”
Focus: Interactive VR Applications• Target applications (VR-Vis), Interactive
Exploration

Hybrid Interfaces
• Use 2D interface elements in a Virtual Environment
+ Well-known
+ Portability
+ Good for abstract 2D info and interaction
- Bulky size
- Clumsy interaction
Goal: Facilitate (more) usable Hybrid Interfaces
May 6, 2006 4
G. de Haan, “Hybrid Interfaces in VEs: Intent and Interaction”
Parallel approach:
• Develop Hybrid interface elements
• Extend Supportive interaction (IntenSelect)
> Combine Interface and Interaction

Hybrid Interfaces
• Previous work• Importing 2D bitmaps• Importing existing toolkits
• Why new development?• Standard? Availability?• 2D + 3D integration
• Interaction integration• Bi-directional communication

Supportive Interaction: IntenSelect
(1) Selection Volume Test
(2) Score contribution
(3) Score accumulation
(4) User Feedback
[dHKP05]: “Intenselect: Using Dynamic Object Rating for Assisting 3D Object Selection”
Problems:• Accuracy
• Small or remote• Ambiguity
• Occlusion or Cluttering
• Complexity• Movement or Shape
