Reduced marker layouts for optical motion capture of hands

Proceedings of the 8th ACM SIGGRAPH Conference on Motion in Games, 2015
We present a method for automatically generating reduced marker layouts for marker-based optical motion capture of human hand motions. Reducing the number of markers on the hand is important to ensure the generated motions are performed in a natural way and indeed a reduced marker set might be a technical requirement should simultaneous body motion ...

Prediction of ground reaction force and joint moments based on optical motion capture data during gait.

Medical Engineering and Physics, 2020
The standard camera- and force plate-based set-up for motion analysis suffers from the disadvantage of being limited to laboratory settings. Since adaptive algorithms are able to learn the connection between known inputs and outputs and generalise this ...

Affective human pose classification from optical motion capture

2017 International Seminar on Intelligent Technology and Its Applications (ISITIA), 2017
In the animation movie production, there is a common tool namely motion capture (mocap) to capture the motion of actors. Using this technology, reconstruction of actors motion is being mapped to drive 3D character in the animation. In the reconstruction process of human motion, there were some significant parameters that affect the quality of the ...

DAMO: A Deep Solver for Arbitrary Marker Configuration in Optical Motion Capture

ACM Transactions on Graphics
Marker-based optical motion capture (mocap) systems are increasingly utilized for acquiring 3D human motion, offering advantages in capturing the subtle nuances of human movement, style consistency, and ease of obtaining desired motion.

Optical Fiber 3D Shape Sensor for Motion Capture

2019 IEEE Conference on Virtual Reality and 3D User Interfaces (VR), 2019
An optical fiber $3\text{D}$ shape sensor for motion capture is reported. The probe is comprised of Bragg grating strain sensors embedded into a $3\text{D}$ -printed polymer fiber substrate, allowing for the continuous assessment of the bending magnitude and direction.

Motion Capture System Using an Optical Resolver

2009
In this paper, we present a novel position measurement method that makes use of a couple of plane light sources created from an IR-LED matrix array and a photo-detector. The light sources emit light with the same frequency, but different phases, while the optical axes of the sources are set up orthogonally.

Automatic Estimation of Skeletal Motion from Optical Motion Capture Data

2008
Utilization of motion capture techniques is becoming more popular in the pipeline of articulated character animation. Based upon captured motion data, defining accurate joint positions and joint orientations for the movement of a hierarchical human-like character without using a pre-defined skeleton is still a potential concern for motion capture ...

HIP JOINT RECONSTRUCTION AND MOTION VISUALIZATION USING MRI AND OPTICAL MOTION CAPTURE

Biomedical Engineering / Biomedizinische Technik, 2003
Patients’ anatomical models are increasingly used for both preoperative planning and postoperative guides. The joints motion visualization opens a new level of understanding and can be a valuable diagnosis tool. We propose here to use optical motion capture to simulate internal motions.

Recording of touch sensing using optical motion capture system

Proceedings of the 2019 11th International Conference on Education Technology and Computers, 2019
In this research, we clarify cognitive process of figure and shape of the visually impaired. We take motion capture of finger position when touch sensing tactile picture, acquire it as coordinate data of fingertip, and quantitatively analyze and evaluate touch sensing.
