DIZI: A Digital Ink Zooming Interface for Document Annotation
Document Annotatio Zooming Interface
2016/5/24
Pen computing devices provide a natural interface for annotating
documents with freeform digital ink. However, digital ink annotations are usually
larger and sloppier than real ink annotations on pa...
Piecewise Image Registration in the Presence of Multiple Large Motions
Registration Large Motions
2016/5/24
We present a technique for computing a dense pixel correspondence
between two images of a scene containing multiple
large, rigid motions. We model each motion with either
a homography (for planar o...
Phrasing Techniques for Multi-Stroke Selection Gestures
phrasing tablets gestures pen input multiple strokes
2016/5/24
Pen gesture interfaces have difficulty supporting arbitrary
multiple-stroke selections because lifting the pen introduces
ambiguity as to whether the next stroke should add to the existing
selectio...
Tumble! Splat! Helping Users Access and Manipulate Occluded Content in 2D Drawings
Layer management 2D drawing occlusion interaction technique
2016/5/24
Accessing and manipulating occluded content in layered 2D drawings
can be difficult. This paper characterizes a design space of
techniques that facilitate access to occluded content. In addition,
w...
Hover Widgets: Using the Tracking State to Extend the Capabilities of Pen-Operated Devices
Hover Widgets pen input gestures tablets
2016/5/24
We present Hover Widgets, a new technique for increasing
the capabilities of pen-based interfaces. Hover Widgets are
implemented by using the pen movements above the
display surface, in the trackin...
Gaze-Based Interaction for Semi-Automatic Photo Cropping
cropping photography composition evaluation eye tracking, visual perception
2016/5/24
We present an interactive method for cropping photographs
given minimal information about the location of important
content, provided by eye tracking. Cropping is formulated in
a general optimizati...
Zone and Polygon Menus: Using Relative Position to Increase the Breadth of Multi-Stroke Marking Menus
Marking menus pie menus positionbased menus pen-based interfaces
2016/5/24
We present Zone and Polygon menus, two new variants of
multi-stroke marking menus that consider both the relative
position and orientation of strokes. Our menus are designed
to increase menu breadt...
This paper addresses the problem of efficiently calculating shadows from environment maps
in the context of ray-tracing. Since accurate rendering of shadows from environment maps
requires hundreds o...
Interactive Cutaway Illustrations of Complex 3D Models
cutaway illustration interactive visualization
2016/5/24
We present a system for authoring and viewing interactive cutaway
illustrations of complex 3D models using conventions of traditional
scientific and technical illustration. Our approach is based on ...
We present an interactive texture painting system that allows the user to author digital images by painting with
a palette of input textures. At the core of our system is an interactive texture synth...
Comparing and Managing Multiple Versions of Slide Presentations
Slide presentations versions distance metrics correspondence alignment
2016/5/24
Despite the ubiquity of slide presentations, managing multiple
presentations remains a challenge. Understanding how
multiple versions of a presentation are related to one another,
assembling new pr...
In his text Visualizing Data, William Cleveland demonstrates how the aspect ratio of a line chart can affect an analyst’s
perception of trends in the data. Cleveland proposes an optimization techniqu...
Photographing Long Scenes with Multi-Viewpoint Panoramas
Multi-Viewpoint Panoramas Photographing Long
2016/5/24
We present a system for producing multi-viewpoint panoramas of
long, roughly planar scenes, such as the facades of buildings along a
city street, from a relatively sparse set of photographs captured...
Perceptual Interpretation of Ink Annotations on Line Charts
Visualization freeform ink annotation visual perception line charts pointing deixis selection
2016/5/24
Asynchronous collaborators often use freeform ink annotations
to point to visually salient perceptual features of line
charts such as peaks or humps, valleys, rising slopes and
declining slopes. We...
Optimizing Content-Preserving Projections for Wide-Angle Images
Wide-Angle Images Optimizing Content-Preserving
2016/5/24
Any projection of a 3D scene into a wide-angle image unavoidably
results in distortion. Current projection methods either bend straight
lines in the scene, or locally distort the shapes of scene obj...
