My long-term research objectives are:-Haptic Landscapes for Virtual Environments,-Biologically inspired control of humanoid robots,-Human biomechanics and neural control of movements.-Haptic Landscapes for Virtual Environments. You feel like going for a jog. However, the temperature outside is below freezing point and you don't like running on a very cold weather. No problem. You put on your ru...

In this paper, dynamic and stability analysis of a flexible cam-follower system is investigated. Equation of motion is derived considering flexibility of the follower and camshaft. Viscous and Coulomb frictions are considered in the rocker arm pivot. The normalized equation of motion of the system is a 2nd- order differential equation with periodic coefficients.&#10Floquet theory is employed to...

piezoelectric microcantilevers (mcs) are a new generation of microbeams used in atomic force microscopes (afms). due to their miniaturization of afms as well as their increased imaging precision and speed, these mcs are more popular than their classical counterparts. given the widespread application of these beams in nanoparticle topography, analysis of their vibrating motion has attracted much...

The aim of this paper is the presentation of a measurement station to determine the anticipation skills in combat sports. Therefore technologies of virtual reality (VR) are being used which create sports specific stimuli. An advantage of this measurement station is that stimuli are visually three dimensional and can be created standardized. Whereas a high immersion as well as a realistic three ...

Many applications using Virtual Reality (VR) require free hand navigation control. This forbids the use of devices such as Joystick, 3D mouse, ... That is generally because hand-based gesture interaction must be dedicated to specific tasks: sculpting or grasping the objects, which compose a virtual scene. With this aim, we present a polyvalent display approach, which allows the system to determ...

This paper addresses the problem of obtaining real-time parameterized simulations of human motion thanks to motion capture data. Contrary to motion graphs that are based on large database of motions, our method relies on per-frame adaptations of motion clips that are selected by a user. For the locomotion example, the user selects a motion that conveys a specific style and drives the character ...

Motek Medical's Computer Aided Rehabilitation Environment (CAREN)-Extended system is a virtual environment primarily used in physical rehabilitation and biomechanical research. This virtual environment consists of a 180 degree projection screen used to display a virtual scene, a 12-camera motion capture system, and a six degree of freedom actuated platform equipped with a dual-belt treadmill an...

The concept of socio-technical systems emphasizes the mutual interrelationship between humans and machines. Accordingly, the objective of ergonomic design of socio-technical systems is to adapt the interaction between humans and machines in such a way that productivity, efficiency and humanity would not contradict each other. Hence, the human has to be considered as an integral part of the syst...
