Relationship between features of augmented reality and user memorization
Found in: 2012 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)
By Yuichiro Fujimoto,Goshiro Yamamoto,Takafumi Taketomi,Jun Miyazaki,Hirokazu Kato
Issue Date:November 2012
pp. 279-280
The objective of this study is to investigate the relationship between the features of augmented reality (AR) and human memorization ability. The basis of this relation is derived from the following features. The AR feature is that AR can provide informati...
 
Augmented prototyping of 3D rigid curved surfaces
Found in: 2012 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)
By Marina Atsumi Oikawa,Igor de Souza Almeida,Takafumi Taketomi,Goshiro Yamamoto,Jun Miyazaki,Hirokazu Kato
Issue Date:November 2012
pp. 307-308
This paper presents an application of Augmented Reality (AR) in Rapid Prototyping (RP) of non-textured rigid curved surfaces. By enhancing the prototypes with AR, evaluation of its design and aesthetic concepts in real-time becomes easier, saving time and ...
 
Local Quadrics Surface Approximation for Real-Time Tracking of Textureless 3D Rigid Curved Objects
Found in: 2012 14th Symposium on Virtual and Augmented Reality (SVR)
By Marina Atsumi Oikawa,Takafumi Taketomi,Goshiro Yamamoto,Makoto Fujisawa,Toshiyuki Amano,Jun Miyazaki,Hirokazu Kato
Issue Date:May 2012
pp. 246-253
This paper addresses the problem of tracking textureless rigid curved objects. A common approach uses polygonal meshes to represent curved objects and use them inside an edge-based tracking system. However, in order to accurately recover their shape, high ...
 
Extrinsic Camera Parameter Estimation Using Video Images and GPS Considering GPS Positioning Accuracy
Found in: Pattern Recognition, International Conference on
By Hideyuki Kume, Takafumi Taketomi, Tomokazu Sato, Naokazu Yokoya
Issue Date:August 2010
pp. 3923-3926
This paper proposes a method for estimating extrinsic camera parameters using video images and position data acquired by GPS. In conventional methods, the accuracy of the estimated camera position largely depends on the accuracy of GPS positioning data bec...
 
Geometrically-Correct Projection-Based Texture Mapping onto a Deformable Object
Found in: IEEE Transactions on Visualization and Computer Graphics
By Yuichiro Fujimoto,Ross T. Smith,Takafumi Taketomi,Goshiro Yamamoto,Jun Miyazaki,Hirokazu Kato,Bruce H. Thomas
Issue Date:April 2014
pp. 540-549
Projection-based Augmented Reality commonly employs a rigid substrate as the projection surface and does not support scenarios where the substrate can be reshaped. This investigation presents a projection-based AR system that supports deformable substrates...
 
Augmented Reality Learning Experiences: Survey of Prototype Design and Evaluation
Found in: IEEE Transactions on Learning Technologies
By Marc Ericson C. Santos,Angie Chen,Takafumi Taketomi,Goshiro Yamamoto,Jun Miyazaki,Hirokazu Kato
Issue Date:January 2014
pp. 38-56
Augmented reality (AR) technology is mature for creating learning experiences for K-12 (pre-school, grade school, and high school) educational settings. We reviewed the applications intended to complement traditional curriculum materials for K-12. We found...
 
Path Expression-based Smoothing of Query Likelihood Model for XML Element Retrieval
Found in: 2013 IIAI International Conference on Advanced Applied Informatics (IIAIAAI)
By Atsushi Keyaki,Jun Miyazaki,Kenji Hatano,Goshiro Yamamoto,Takafumi Taketomi,Hirokazu Kato
Issue Date:August 2013
pp. 296-300
In this paper we propose a path expression-based smoothing method of query likelihood model for XML element retrieval (QLMER). Though the query likelihood model, one of the statistical language models, is regarded as an accurate term weighting scheme in do...

Towards participatory design for contextual visualization in education using augmented reality x-ray
Found in: Proceedings of the 4th Augmented Human International Conference (AH '13)
By Goshiro Yamamoto, Takafumi Taketomi
Issue Date:March 2013
pp. 241-241
We propose Augmented Reality (AR) x-ray as an educational tool for contextual visualization--presenting virtual information in the rich context of a real environment. Teachers and students evaluated a state-of-the-art implementation of AR x-ray. Results sh...
     
Fast and incremental indexing in effective and efficient XML element retrieval systems
Found in: Proceedings of the 14th International Conference on Information Integration and Web-based Applications & Services (IIWAS '12)
By Atsushi Keyaki, Goshiro Yamamoto, Hirokazu Kato, Jun Miyazaki, Kenji Hatano, Takafumi Taketomi
Issue Date:December 2012
pp. 157-166
A method for fast and incremental indexing, with both effective and efficient query processing, is proposed for XML element retrieval. When frequent document updates occur on the Web, they must be handled to maintain the effectiveness of the search system....
