Vertigo

 
 

Vertigo is a dynamic and interactive projection mapping project that transforms the viewer’s perception of the space and object. Via motion capture and lenticular effects, the geometry subverts the dimension and depth of the perspective as one interacts with it .

Conceptualization

Color and space has been the central topic for graphic design and projection mapping. In Josef Albers’ “Interaction of Color“ and “Transformation of a Scheme,” he exemplifies several case studies of 2D geometry that allows for multiple readings of the embedded 3D space. Using contrasting color and slight shift of saturation and brightness of the color, I created a series of “impossible geometry” that could be read three-dimensionally. Served as the base of our projection mapping project, this exercise creates some interests for us in using basic geometry and contrasting colors to change one’s perception of 3D planes.

 
 
 

Process

In processing, I tested out several different interactive animation strategies to generate the perspective distortion effects. Using yellow and purple, two contrasting colors, I generated line works that frames the 3D object.

We then uses Xbox Kinect to detect movements in order to input the distance perimeter into grasshopper and processing via OscP5 library. The distance of the viewer correlates different phases of movement.
