Autonomous Guided Vehicles (AGVs) using omnidirectional wheels can change their moving direction flexibly without the use of steering wheel. Is it possible that a vehicle with standard pneumatic (as in normal vehicle) its by technique regulating driving torque supplied to each wheel? In this article, simulated motion trajectories two types vehicles were presented, are Mecanum and (normal wheels...

Along with the rapid development of information technology, computers play an increasingly prominent and important role. One current trend is to use computers as instruments for physical rehabilitation. In this study, we introduce a new hand motion assessment and rehabilitation system. This system assesses a user's grip strength and records the sudden changes in air pressure through a circuit a...

Hand motion capturing is one of the most important parts of gesture interfaces. Many current approaches to this task generally involve a formidable nonlinear optimization problem in a large search space. Motion capturing can be achieved more cost-efficiently when considering the motion constraints of a hand. Although some constraints can be represented as equalities or inequalities, there exist...

This paper introduces a novel and efficient segmentation method designed for articulated hand motion. The method is based on a graph representation of temporal structures in human hand-object interaction. Along with the method for temporal segmentation we provide an extensive new database of hand motions. The experiments performed on this dataset show that our method is capable of a fully autom...

We present an algorithm for extracting and classifying two-dimensional motion in an image sequence based on motion trajectories. First, a multiscale seg-mentation is performed to generate homogeneous regions in each frame. Regions between consecutive frames are then matched to obtain 2-view correspondences. AAne transformations are computed from each pair of corresponding regions to deene pixel...

Visually capturing human hand motion requires estimating the 3D hand global pose as well as its local finger articulations. This is a challenging task that requires a search in a high dimensional space due to the high degrees of freedom that fingers exhibit and the self occlusions caused by global hand motion. In this paper we propose a divide and conquer approach to estimate both global and lo...

As the number of people diagnosed with movement disorders is increasing, it becomes vital to design techniques that allow the better understanding of human brain in naturalistic settings. There are many brain imaging methods such as fMRI, SPECT, and MEG that provide the functional information of the brain. However, these techniques have some limitations including immobility, cost, and motion ar...

starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...
