Real-time Myoelectric Control in a Virtual Environment to Relate Accuracy and Usability
INTRODUCTION Many clinically available, upper-extremity prosthetic limbs provide myoelectric control of a single device, such as a hand, elbow, or wrist. Most commonly, these systems yield control information from myoelectric signal (MES) amplitude [1] or rate of change of MES [2]. Such systems have been beneficial; however, prosthetic users would no doubt find enhanced functionality and usabil...
متن کاملReal-Time Control of a Virtual Human Using Minimal Sensors
We track, in real-time, the position and posture of a human body, using a minimal number of 6 DOF sensors to capture full body standing postures. We use 4 sensors to create a good approximation of a human operator's position and posture, and map it on to our articulated computer graphics human model. The unsensed joints are positioned by a fast inverse kinematics algorithm. Our goal is to reali...
متن کاملWalking Through a Very Large Virtual Environment in Real-time
Users expect high and constant rendering frame rates when they interactively navigate in a Virtual Environment (VE). However, when the VE is too large to t into the main memory, the frame rates can become unacceptable. In this paper, we combine walkthrough semantics and database techniques, such as indexing, caching and prefetching, to improve the performance of walkthrough of a very large VE. ...
متن کاملReal-Time Fluid Simulation in a Dynamic Virtual Environment
imulating physically realistic complex fluid behaviors in a distributed interactive simulation (DIS) presents a challenging problem for computer graphics researchers. Such behaviors include driving boats through water, stirring liquids, blending differently colored fluids, mixing insolubles such as oil and water, rain falling and flowing on a terrain, and fluids interacting. These capabilities ...
متن کاملA Virtual Environment Assessment of a Novel Pattern Recognition Based Myoelectric Control Scheme
This work compared a novel pattern recognition based myoelectric control system to a system based on conventional control and another state of the art pattern recognition system. The results showed that the proposed system provides a more usable system as assessed qualitatively and quantitatively through a modified virtual clothespin test. Furthermore, the proposed system was designed to have a...
