In this paper, we describe a method to manipulate a paintbrush for a painting robot. The robot has multi-fingered hands and a stereo vision system. It grasps a paintbrush with its own hand and paints a picture on a canvas. Because a brush is deformable, adequate control of a paintbrush is a challenging task. It is necessary to develop several manipulation methods with feedback control using bot...

Spatial data is frequently used in urban planning contexts to support decision-making. This data can be used to plan routes through the city for public transportation or to designate zones for planning new businesses and residences. Unfortunately, few tools exist that allow non-programmers to rapidly utilize spatial data to create such plans. In this poster, we present SpaceSketch, a tool for r...

Interaction at close proximity with wall sized interactive displays presents interesting interface challenges in that not all parts of the display are easily visible or reachable by a user without significant physical movement. We address this challenge by developing interaction and visualization techniques for bridging distances and organizing content to facilitate easy access to all displayed...

We take a novel approach to Non-Photorealistic Rendering by adapting genetic programming in combination with computer graphics drawing techniques. As a GP tree is evaluated, upon encountering certain nodes referred to as “Draw” nodes, information contained within such nodes are sent to one of three virtual canvasses and a mark is deposited on the canvas. For two of the canvasses the user is abl...

The aim of this research is to demonstrate the usefulness of speckle, a trait of an expanded laser beam, for the non-destructive testing of artwork in both the imaging of subsurface structure and the quantitative detection of physical movement of canvas Laser Speckle Contrast Method (LSCI) is a useful method for the viewing of subsurface layers and movement. By investigating the statistical pro...
