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

Dynamic Optical Brushes

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!
