Shadow reaching

Garth Shoemaker, Anthony Tang, Kellogg S. Booth
2007 Proceedings of the 20th annual ACM symposium on User interface software and technology - UIST '07  
We introduce Shadow Reaching, an interaction technique that makes use of a perspective projection applied to a shadow representation of a user.  ...  We describe three prototype implementations that illustrate the technique, examining the advantages of using shadows as an interaction metaphor to support single users and groups of collaborating users  ...  We propose a new interaction technique, dubbed Shadow Reaching, which employs a perspective-projected shadow of the user on the display for interaction.  ...

Freeform Shadow Boundary Editing

O. Mattausch, T. Igarashi, M. Wimmer
2013 Computer graphics forum (Print)  
Using a mesh created from the new shadow boundaries (E), a shadow volume algorithm creates plausible shadows when changing the scene configuration (F).  ...  All cases are handled with a single intuitive interface, be it soft shadows, or (self-)shadows on arbitrary receivers.  ...  Acknowledgments This work has been supported by funding from the Japan Society for the Promotion of Science (JSPS) and by the EU FP7 People Programme (Marie Curie Actions) under REA Grant Agreement no.  ...

Teleology's long shadow

A. Werth, D. Allchin
2020 Evolution: Education and Outreach  
We describe the ubiquity of teleological language and thinking throughout biology, as a context for understanding how students think about evolution, as well.  ...  Recent research documents a deep human psychological tendency to attribute purpose or intent (and thus normative meaning) to natural phenomena. We present a possible evolutionary explanation.  ...  shed light on how to deal with their far-reaching ubiquity).  ...

Pipeline rendering: interactive refractions, reflections and shadows

Paul J. Diefenbach, Norman I. Badler
1994 Displays (Guildford)  
We provide recursive reflections through the use of secondary viewpoints, and present a method for using a homogeneous 2D projective image mapping to extend this method for refractive surfaces.  ...  We provide recursive reflections through the use of secondary viewpoints, and present a method for using a homogeneous 2D projective image mapping to extend this method for refractive surfaces.  ...  This figure displays the complex shadow patterns caused by objects on both sides of a refracting surface.  ...

Leaving the Shadow: A Configurational Approach to Explain Post-identification Outcomes of Shadow IT Systems

Daniel Fürstenau, Hannes Rothe, Matthias Sandner
2020 Business & Information Systems Engineering  
When a shadow IT system is identified, the organization has to decide on the future of this system.  ...  The study uses a configurational perspective to explain outcomes of shadow IT system identification, as well as the mechanisms and contextual conditions which bring them about.  ...  We thank the Senior Editor and the Associate Editor as well as the reviewers for their sustained guidance during the entire review process. For helpful inputs and comments, we also thank Dr.  ...

Setting the Record Straighter on Shadow Banning [article]

Erwan Le Merrer and Benoit Morgan and Gilles Trédan
2021 arXiv   pre-print
We then pose two hypotheses for the phenomenon: i) limitations are bugs, as claimed by Twitter, and ii) shadow banning propagates as an epidemic on user-interactions ego-graphs.  ...  We then show some interesting correlation with hypothesis ii), suggesting that the interaction topology is a good indicator of the presence of groups of shadow banned users on the service.  ...  ACKNOWLEDGEMENTS We thank the shadowban.eu initiative, that provided tests to individuals for spotting shadow banning, and that distributed the open-source test code.  ...

Shadow generation for volumetric data sets

Rolf H. van Lengen, Jörg Meyer, Mathias Matzat, Hans Hagen
1998 The Visual Computer  
Our algorithm, integrated into a hybrid rendering system for medical data sets, is based on a shadow Z-buffer technique for fast and efficient shadow generation.  ...  There are two representations of the same data set: we use a view-independent approximation to display shadows and the original representation of the volume for object visualization in full precision.  ...  The interval depends on the dimension of a given scene and requires interactive searches to find a practical value. Our method tries to avoid the necessity of interactive manipulation.  ...

The shadow system in coordinate space: The shadow system in coordinate space: A locally explicable system that violates Bell's inequality [article]

Warren Leffler
2009 arXiv   pre-print
Following up on the negation of EPNT using shadow streams, we analyze the experimental outcomes in a standard two-particle interferometer.  ...  Carrying out the negation of EPNT leads to the concept of a "shadow stream."  ...  But as John Wheeler and Martin Gardner point out [44] for action-at-a-distance the particles must "remain connected, even though light years apart, by a nonlocal subquantum level that no one understands  ...

Religion and the Shadow Economy

Importantly, the normative impact of religion may reach beyond its immediate followers. Ethical norms which have a religious past and origin may survive even if a society becomes largely atheist.  ...  By analyzing these interlinkages, we hope to add a new dimension to the literature on the shadow economy and also expand on the economics of religion, since it has not been investigated so far to what  ...  APPENDIX 1: DATA DEFINITION AND SOURCES APPENDIX A2: DESCRIPTION OF RELIGIOUS DENOMINATIONS Jewish Orthodoxy The perspective of Jewish orthodoxy on the respect of a state's rule in general and tax  ...
