Data-Driven Haptic Modeling and Rendering of Viscoelastic Behavior Using Fractional Derivatives

Autor: Hojun Cha, Amit Bhardwaj, Seungmoon Choi

Publikováno v: IEEE Access, Vol 10, Pp 130894-130907 (2022)

Data-driven modeling and rendering is a general approach in haptics aiming to provide highly accurate haptic perceptual experiences simulating complex real physical dynamics, such as deformable or textured objects. A prevalent problem in the present

Prediction of Specific Anxiety Symptoms and Virtual Reality Sickness Using In Situ Autonomic Physiological Signals During Virtual Reality Treatment in Patients With Social Anxiety Disorder: Mixed Methods Study

Autor: Joo Young Chun, Hyun-Jin Kim, Ji-Won Hur, Dooyoung Jung, Heon-Jeong Lee, Seung Pil Pack, Sungkil Lee, Gerard Kim, Chung-Yean Cho, Seung-Moo Lee, Hyeri Lee, Seungmoon Choi, Taesu Cheong, Chul-Hyun Cho

Publikováno v: JMIR Serious Games, Vol 10, Iss 3, p e38284 (2022)

BackgroundSocial anxiety disorder (SAD) is the fear of social situations where a person anticipates being evaluated negatively. Changes in autonomic response patterns are related to the expression of anxiety symptoms. Virtual reality (VR) sickness ca

Maximum Likelihood Estimation of Continuous-time Diffusion Models for Exchange Rates

Autor: Seungmoon Choi, Jaebum Lee

Publikováno v: East Asian Economic Review, Vol 24, Iss 1, Pp 61-87 (2020)

Five diffusion models are estimated using three different foreign exchange rates to find an appropriate model for each. Daily spot exchange rates expressed as the prices of 1 euro, 1 British pound and 100 Japanese yen in US dollars, respectively deno

Hybrid Framework for Haptic Texture Modeling and Rendering

Autor: Sunghwan Shin, Seungmoon Choi

Publikováno v: IEEE Access, Vol 8, Pp 149825-149840 (2020)

We present a hybrid framework for the modeling and rendering of both homogeneous and inhomogeneous textures with high realism by combining force and vibration feedback. Given a real texture sample, we first capture a force-feedback model using photom

Perceptual Space of Superimposed Dual-Frequency Vibrations in the Hands.

Autor: Inwook Hwang, Jeongil Seo, Seungmoon Choi

Publikováno v: PLoS ONE, Vol 12, Iss 1, p e0169570 (2017)

The use of distinguishable complex vibrations that have multiple spectral components can improve the transfer of information by vibrotactile interfaces. We investigated the qualitative characteristics of dual-frequency vibrations as the simplest comp
