ZombieBoard Whiteboard Scanner
ZombieBoard is a whiteboard scanner for offices, conference rooms, and open areas. A computer-controlled video camera takes overlapping snapshots of the whiteboard, which are then electronically "stitched" together to form a relatively high resolution mosaic image that can be printed, faxed, or displayed. Each ZombieBoard at PARC runs a small real-time computer vision system in support of a Diagrammatic User Interface permitting users to issue commands by drawing on the whiteboard itself.
Perceptually-Supported Sketch Editing
When we create a sketch or drawing either on paper or with a computer graphics
program, we "see" not just the elemental
marks on the surface, but salient and sensible visual objects.
Computer vision techniques of perceptual
organization make possible a new class of
perceptually-supported image editing tools enabling computer-assisted
drawing programs to engage users in terms closer to the user's own visual
constructs. In collaboration with Tom Moran, I have built a prototype sketch
editing system called, PerSketch (also called FancyTivoli),
that explores this new space of WYPIWYG (What You Perceive Is What You Get)
image editing tools. UIST '94.
Text Topic Inference Using The Multiple Cause Mixture Model
Apart from applications in document image analysis, my work in
inferring factoral causal structure underlying binary data finds an application
in inferring the topic structure of a corpus of documents.
This work was done in collaboration with Marti Hearst and intern Mehran
Sahami. ML '96.
Vision: Cooperative Workspaces
ZombieBoard is an example of Ubiquitous Computing
technology---computers help you in your daily life and work without your having
to deal with them as conventional computers with monitors, operating systems,
keyboards, and all that nonsense. My colleagues in the Perceptual Documents
Area and I continue to explore other ways in which computer vision can
contribute to computationally enhanced physical environments through a focus on
document image analysis.
