Urban Traffic Signal Control Based on Distributed Constraint Satisfaction
Found in: Hawaii International Conference on System Sciences
By Kazunori Mizuno, Yukio Fukui, Seiichi Nishihara
Issue Date:January 2008
pp. 65
Urban traffic problems including traffic accidents and traffic congestion or jams have been very serious for us. Urban traffic flow simulation has been important for mak- ing new control strategies that can reduce traffic jams. In this paper, we propose a ...
   
Development of a Force and Torque Hybrid Display
Found in: World Haptics Conference
By Norio Nakamura, Yukio Fukui
Issue Date:March 2005
pp. 633-634
Multimodal interfaces with the five senses attract a great deal of attention as for the next generation multimedia interface. Especially, the interfaces with additional tactile sensation and force feedback enable us to perform pointing and manipulation ope...
   
Generating Autonomous Time-Varying Virtual Cities
Found in: Cyberworlds, International Conference on
By Masanobu Honda, Kazunori Mizuno, Yukio Fukui, Seiichi Nishihara
Issue Date:November 2004
pp. 45-52
We propose an approach to generating virtual cities that vary dynamically over time, focusing on the layout of artificial elements such as building, roads, and traffic lights. We first define an environment vector as the amount of features reflecting econo...
 
Shape Identification Performance and Pin-matrix Density in a 3 Dimensional Tactile Display
Found in: Virtual Reality Annual International Symposium
By Makoto Shimojo, Masami Shinohara, Yukio Fukui
Issue Date:March 1997
pp. 180
Tactile display devices use an array of pins mounted in the form of a matrix to present three-dimensional shapes to the user by raising and lowering the pins. With a denser matrix of mounted pins, it can be expected that shape identification will become ea...
 
Development of Fingertip Type Non-grounding Force Feedback Display
Found in: World Haptics Conference
By Yukio FUKUI
Issue Date:March 2007
pp. 582-583
Force feedback displays to represent virtual objects with non-grounding and no reaction base on the human body are convenient and effective for mobile uses. Especially, these sensations are expected to be applied to ubiquitous/mobile/wearable interfaces fo...
 
Generating folding sequences from crease patterns of flat-foldable origami
Found in: ACM SIGGRAPH 2013 Posters (SIGGRAPH '13)
By Hugo A. Akitaya, Jun Mitani, Yoshihiro Kanamori, Yukio Fukui
Issue Date:July 2013
pp. 1-1
The most common form to convey origami is through origami diagrams, which are step-by-step sequences, composed of figures that represent the state of the folded paper, in combination with lines and arrows indicating the position of the folds and the moveme...
     
Multiresolution wavelet analysis of shape orientation for 3d shape retrieval
Found in: Proceeding of the 1st ACM international conference on Multimedia information retrieval (MIR '08)
By Jun Mitani, Seiichi Nishihara, Yukio Fukui, Zhenbao Liu
Issue Date:October 2008
pp. 1-1
In the present paper, we propose a novel 3D shape descriptor by performing multiresolution wavelet analysis on shape orientation. We consider the spatial orientation of the polygon surfaces of a shape as important information and characterize this informat...
     
The sense of physically crossing paths: creating a soft initiation in HyperMirror communication
Found in: CHI '00 extended abstracts on Human factors in computer systems (CHI '00)
By Juli Yamashita, Osamu Morikawa, Yukio Fukui
Issue Date:April 2000
pp. 183-184
In this report we discuss adding a new sensor which allows the user to perceive changes in HyperMirror space. The sensation caused by the tactile displays allows the user to perceive other users' movements. The tactile signal is not intrusive, although it ...
     
Plane-shape perception using point-contact type force feedback device
Found in: ACM SIGGRAPH 98 Conference abstracts and applications (SIGGRAPH '98)
By Cai Yi, Juli Yamashita, Osamu Morikawa, Robert W. Lindeman, Yukio Fukui
Issue Date:July 1998
pp. 274
This paper describes a physically-based rendering system tailored to the demands of lighting design and architecture. The simulation uses a light-backwards ray-tracing method with extensions to efficiently solve the rendering equation under most conditions...
     
Feature based haptic rendering: architecture, protocol, and application
Found in: ACM SIGGRAPH 97 Visual Proceedings: The art and interdisciplinary programs of SIGGRAPH '97 (SIGGRAPH '97)
By Cai Yi, Juli Yamashita, Yukio Fukui
Issue Date:August 1997
pp. 182
This paper describes a physically-based rendering system tailored to the demands of lighting design and architecture. The simulation uses a light-backwards ray-tracing method with extensions to efficiently solve the rendering equation under most conditions...
