Evaluation of Areal Touch Feedback for Palpation Simulation
Found in: Visualization Conference, IEEE
By Jinah Park, Sang Youn Kim, Ki Uk Kyung, Dong Soo Kwon
Issue Date:October 2005
pp. 100
Visualization at large is the process of converting the data into a form that can be easily perceived by the human. While the visual information is the most dominant sensory input for perceiving an object, the touch feedback provides the main perception fo...

Visualizing Marine Environmental Changes to the Saemangeum Coast
Found in: IEEE Computer Graphics and Applications
By Jinah Kim, Jinah Park
Issue Date:November 2012
pp. 82-87
The Saemangeum Coast, located on the west side of the Korean peninsula, is undergoing a 30-year land reclamation project involving approximately 40 kilohectares. Because this project will drastically change the marine environment, monitoring and analyzing ...
 
Multiple-Contact Representation for the Real-Time Volume Haptic Rendering of a Non-Rigid Object
Found in: Haptic Interfaces for Virtual Environment and Teleoperator Systems, International Symposium on
By Sang-Youn Kim, Jinah Park, Dong-Soo Kwon
Issue Date:March 2004
pp. 242-249
This paper presents a fast haptic rendering method providing the sense of touch from a virtual volumetric non-rigid object when a human operator interacts with the object at multiple points. Previously, we have proposed a fast volume haptic rendering metho...
 
Shape Retaining Chain Linked Model for Real-Time Volume Haptic Rendering
Found in: Volume Visualization and Graphics, IEEE Symposium on
By Jinah Park, Sang-Youn Kim, Seung-Woo Son, Dong-Soo Kwon
Issue Date:October 2002
pp. 65-72
Haptic rendering is the process of computing and generating forces in response to user interactions with virtual objects. While we speak of real-time volume rendering for visualization, we are still very much limited to surface models for manipulation due ...
 
Visualizing Spray Paint Deposition in VR Training
Found in: Virtual Reality Conference, IEEE
By Daeseok Kim, Youngwoo Yoon, Sunyu Hwang, Geehyuk Lee, Jinah Park
Issue Date:March 2007
pp. 307-308
We present a real-time simulation of spray painting incorporated into a VR environment as an alternative training system for ship-building industries. The system allows the user to try out a painting work on life-size structures with a spray gun. Our goal ...
 
3D Object Manipulation Using Virtual Handles with a Grabbing Metaphor
Found in: IEEE Computer Graphics and Applications
By Taeho Kim,Jinah Park
Issue Date:May 2014
pp. 30-38
This technique lets users manipulate 3D objects as if they had actually grabbed them. It employs a grabbing metaphor to provide the mapping protocol for finding the desired reference frame for the object. The technique projects the user's hand into the vir...
 
Progressive mesh cutting for real-time haptic incision simulator
Found in: ACM SIGGRAPH ASIA 2010 Posters (SA '10)
By Jihwan Park, Jinah Park, Seokyeol Kim
Issue Date:December 2010
pp. 1-1
Incision is one of the most critical actions in the medical treatment, and the constant practice is required to be skillful at it. Accordingly, researchers have strived to simulate the incision in the virtual environment. Recently, several methods for mesh...
     
Efficient multi-pass welding training with haptic guide
Found in: ACM SIGGRAPH ASIA 2009 Posters (SIGGRAPH ASIA '09)
By Dongsik Jo, Gun Lee, Jinah Park, Jinseong Choi, Ungyeon Yang, Yongwan Kim
Issue Date:December 2009
pp. 1-1
Recent progress in computer graphics and interaction technologies has brought virtual training in many applications. Virtual training is very effective at dangerous or costly works. A represetative example is a welding training in automobile, shipbuilding,...
     
Physically based grasping and manipulation method using pre-contact grasping quality measure
Found in: Proceedings of the 16th ACM Symposium on Virtual Reality Software and Technology (VRST '09)
By Jinah Park, Jinseong Choi, Yongwan Kim
Issue Date:November 2009
pp. 253-254
While the human hand is the most natural tool for interacting with objects, hand interaction with virtual objects is still a challenging research field. We recognize that common hand interaction involves two separate stages with different aspects: One is t...
     
Virtual bone drilling for dental implant surgery training
Found in: Proceedings of the 16th ACM Symposium on Virtual Reality Software and Technology (VRST '09)
By Jinah Park, Kimin Kim
Issue Date:November 2009
pp. 91-94
Mechanical removal of bone material is the most critical procedure during dental implant surgery because it can jeopardize patient safety in several ways such as damage in the mandibular canal and piercing of the maxillary sinus. With recognition of the ef...
     
Tuning viewing parameters for efficient and accurate 3D interaction
Found in: Proceedings of the 2005 international conference on Augmented tele-existence (ICAT '05)
By Dong Wook Lee, Jinah Park
Issue Date:December 2005
pp. 287-287
We hypothesize that one of the reasons for the depth perception problem is the difference between the result for the viewing frustum of virtual world and the scene of the real world. To verify our hypothesis, we experiment simple locating tasks whose viewi...
