We present an interactive method that allows animated characters to navigate through cluttered environments. Our characters are equipped with a variety of motion skills to clear obstacles, narrow passages, and highly constrained environment features. Our control method incorporates a behavior model into well-known, standard path planning algorithms. Our behavior model, called deformable motion,...

Introduction: In radiotherapy with external surrogates, exact information of tumor position is one of the key factors that improves treatment delivery. Many dynamic tumors in thorax region of patient move mainly due to respiration and are known as intra-fractional motion error that must be compensated, as well. One of clinical strategy is using Stereotactic Body Radiation Thera...

rolling-based seismic isolation systems, in which rollers of circular or non-circular section are used, are less expensive and easier to manufacture. however, this type of isolation suffers from either lack of restoring or re-centering capability, or weakness against uplift forces. to resolve the first shortcoming the use of elliptical as well as pillow-shape rolling parts has been suggested, a...

Motion capture techniques play an important role in computer animation. Because the cost of motion capture data is relatively high and the virtual environment changes frequently in actual applications, researchers in this area focus their work on developing algorithms for editing the capture motion data, and synthesizing new motions from available motion database. Although abundant work has bee...

Character animations produced with motion capture data have many of the stylistic details seen in human motion while those generated with simulation are physically realistic for the dynamic parameters of the character. We combine these two approaches by tracking and modifying human motion capture data using dynamic simulation and constraints. The tracking system generates motion that is appropr...

Various realistic collaboration technologies have emerged in the context of COVID-19 pandemic. However, as existing virtual reality (VR) systems generally employ an inverse kinematic method using a head-mounted display and controller, user character cannot be accurately matched. Accordingly, immersion level VR experience is low. In this study, we propose remote system that uses motion capture t...

Recently, performance-driven facial animation has been popular in various entertainment area, such as game, animation movie, and advertisement. With the easy use of motion capture data from a performer’s face, the resulting animated faces are far more natural and lifelike. However, when the characteristic features between live performer and animated character are quite different, expression map...

The objective of this project is to use motion capture to track the motions of a human subject, above the waist, and then map these motions onto a humanoid robot in real-time, essentially making the robot a puppet and the human the puppeteer. This puppeteer will control the robot while wearing a virtual reality rig that allows the puppeteer to see what the robot sees. The robot that will be use...

Virtual avatar control is an important technology in computer games and virtual reality. However, the traditional experience requirement to the interactive entertainment. This paper proposes an intuitive interaction approach which allows the user to control the virtual character by his body performance. The user s behavior is captured by measuring the accelerometer and magnetometer from the mot...
