System improvements in Mobile Haptic Interface
Found in: World Haptics Conference
By In Lee, Inwook Hwang, Kyung-Lyoung Han, Oh Kyu Choi, Seungmoon Choi, Jin S. Lee
Issue Date:March 2009
pp. 109-114
A Mobile Haptic Interface (MHI), a force-feedback haptic interface with a mobile base, allows to render very large virtual objects in a safe and portable manner. In this paper, we present a novel MHI system, featured with: 1) extended horizontal workspace ...
 
Haptizing Surface Topography with Varying Stiffness Based on Force Constancy: Extended Algorithm
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Jaeyoung Cheon, Inwook Hwang, Gabjong Han, Seungmoon Choi
Issue Date:March 2008
pp. 193-200
This article introduces a novel haptization method for rendering surface topography with varying stiffness via a force-feedback haptic interface. Previously, we showed that when surface topography with varying stiffness is rendered with the conventional pe...
 
Consonance of Vibrotactile Chords
Found in: IEEE Transactions on Haptics
By Yongjae Yoo, Inwook Hwang, Seungmoon Choi
Issue Date:January 2014
pp. 3-13
This paper is concerned with the perception of complex vibrotactile stimuli in which a few sinusoidal vibrations with different frequencies are superimposed. We begin with an observation that such vibrotactile signals are analogous to musical chords in whi...
   
Real-Time Dual-Band Haptic Music Player for Mobile Devices
Found in: IEEE Transactions on Haptics
By Inwook Hwang, Hyeseon Lee, Seungmoon Choi
Issue Date:July 2013
pp. 340-351
We introduce a novel dual-band haptic music player for real-time simultaneous vibrotactile playback with music in mobile devices. Our haptic music player features a new miniature dual-mode actuator that can produce vibrations consisting of two principal fr...
 
Vibrotactile Perceived Intensity for Mobile Devices as a Function of Direction, Amplitude, and Frequency
Found in: IEEE Transactions on Haptics
By Inwook Hwang, Jongman Seo, Myongchan Kim, Seungmoon Choi
Issue Date:July 2013
pp. 352-362
Vibrotactile rendering is an emerging interaction method for information transmission in mobile devices, replacing or supplementing visual and auditory displays. To design effective vibrotactile actuators or display algorithms, an understanding of the perc...
 
Genetic approaches for graph partitioning: a survey
Found in: Proceedings of the 13th annual conference on Genetic and evolutionary computation (GECCO '11)
By Byung-Ro Moon, Inwook Hwang, Jin Kim, Yong-Hyuk Kim
Issue Date:July 2011
pp. 473-480
The graph partitioning problem occurs in numerous applications such as circuit placement, matrix factorization, load balancing, and community detection. For this problem, genetic algorithm is a representative approach with competitive performance with many...
     
Multi-attractor gene reordering for graph bisection
Found in: Proceedings of the 8th annual conference on Genetic and evolutionary computation (GECCO '06)
By Byung-Ro Moon, Inwook Hwang, Yong-Hyuk Kim
Issue Date:July 2006
pp. 1209-1216
We propose a new gene reordering scheme for the graph bisection problem. Our gene reordering starts with two or more vertices to capture the clustering structure of graphs effectively. We devised a chromosome repairing method for hybrid genetic search, whi...
