Ball trajectory data is one of the most fundamental and useful pieces of information for evaluating players' performance and analyzing game strategies in ball sports. Although vision-based object tracking techniques have been developed to analyze sports ...

The deployment of machine learning in real-life computer vision applications is often subject to the degraded input data by various noise sources and time-varying conditions. Continual re-training is one potential solution to adapt to the real-time noise ...

The pandemic has contributed to the increased digital content development for remote experiences. Notably, museums have begun creating virtual exhibitions using 360-videos, providing a sense of presence and high level of immersion. However, 360-video ...

Recent VR HMDs embed various bio-sensors (e.g., EEG, eye-tracker) to expand the interaction space. Steady-state visual evoked potential (SSVEP) is one of the most utilized methods in BCI, and recent studies are attempting to design novel VR interactions ...

As the utilization of VR is expanding across diverse fields, research on devising attentional cues that could optimize users' task performance in VR has become crucial. Since the cognitive load imposed by the context and the individual's cognitive ...

Accurate gait detection is crucial in utilizing the ample health information embedded in it. Vision-based approaches for gait detection have emerged as an alternative to the exacting sensor-based approaches, but their application has been rather ...

• A reliable vision-based approach for gait event detection is proposed.
• The proposed method achieved outstanding performance in detecting both standard and peculiar gaits.
• The gait events were accurately detected regardless of ...

Joint agency, a group-level sense of agency, has been studied as an essential social cognitive element while engaging in collaborative tasks. The joint agency has been actively investigated in diverse contexts (e.g., performance, reward schedules, and ...

Nowadays, telepresence systems based on the Extended Reality (XR) system are actively developed and used for remote collaboration due to COVID-19. Still, several issues, such as limited traversable space in Virtual Reality (VR) and require all ...

In this study, we explore how spatial configurations can be reflected in determining the threshold range of Relative Translation Gains (RTGs), a translation gain-based Redirected Walking (RDW) technique that scales the user’s movement in Virtual ...

A growing number of VR games are published in the market as head-mounted devices (HMD) become more widespread. However, most VR games are targeted for a single-player audience, and cross-platform VR experiences where multiple players are engaged have ...

Wireless ad-hoc network which has not been supported by centralized infrastructure is widely used because of its utilitarian ability. Thanks to a low-complex aspect, It is favorable for IoBT (Internet of Battlefield Things) applications. Propagation ...

The demand for pet monitoring devices is growing due to the increasing number of one-person households raising pets. However, current monitoring methods using video camera entail various problems, which may lead to discontinued usage. To overcome this ...

In IEEE 802.11ad, single carrier (SC) and orthogonal frequency-division multiplexing (OFDM) transmissions are supported as mandatory and optional transmission schemes, respectively. Both transmission schemes can be implemented with a minimum increase in ...

This paper presents a systematic design method of a controller using the discrete fuzzy PI control and the particle swarm optimization (PSO). Unlike a conventional PI controller, the discrete fuzzy PI controller has variable gains according to its input ...

We propose a practical algorithm for stabilizing panoramic video. We represent a stabilizing rotation by using exponential coordinates and compute the stabilizing rotation for all video frames by smoothing the shaky trajectories of visual features on the ...

Data driven models of human poses and soft-tissue deformations can produce very realistic results, but they only model the visible surface of the human body and cannot create skin deformation due to interactions with the environment. Physical ...

We propose an enhanced time-delay controller (TDC) for robot manipulators using Takagi-Sugeno-Kang (TSK) fuzzy control systems. The proposed controller has three terms: a time-delay estimation (TDE) term to estimate and cancel continuous nonlinearities of ...

A fast and scalable graph processing method becomes increasingly important as graphs become popular in a wide range of applications and their sizes are growing rapidly. Most of distributed graph processing methods require a lot of machines equipped with ...

As a novel composite material for laser ultrasound transducer, candle soot nanoparticles polydimethylsiloxane (CSPs-PDMS) has been demonstrated to generate high frequency, broadband, and high-amplitude ultrasound waves. In this study, we investigated the ...

This paper presents an accurate position control for a pump-controlled electro-hydraulic actuator (EHA) using time-delay estimation (TDE). The TDE technique is used to estimate nonlinear terms of EHA, which is a third order nonlinear system. The measured ...
