Outline
• Why Dynamir?• Possibilities!• Implementation• Applications
Goal: Dynamic mirrors are fun and useful!
Manipulating Reflections• Perceived reflection of an object
depends on :- Observer's position /mirror - Object position / mirror - Normals of the mirror surface
• Manipulating reflectionsinvolves defining normals at all points of the mirror
Dynamir : Dynamic Mirror Brushes
→ not very practical / efficient
Dynamic Optical Brushes
• Local deformations of the mirror surface• aimed at a group of observers• affect a certain region of interest (ROI)• attributes define the effect that they create
• Position and Orientation : ROI Selection, Position of ROI, Viewing Angle
• Curvature : Zooming in and out on ROI• Size and Shape: Numbers of observers / Size of ROI
HIPS mirror (a) is controlled using ShapeClips (c) by sensing light intensity on LCD screen (b)
Vertical reflection (d) is overlapped with 3D Screen (f)using half-silvered mirror (e)
User tracking by Asus Xtion (h), user input with Leap (g)
Implementation
Conclusion
• Dynamic mirror brushes allow interactive optical manipulation
• Change the shape, size and position of reflected objects!
• Augmented reality interaction• Practical applications • Easy and effective implementation
Goal: Dynamic mirrors are fun and useful!
