We describe an experimental arrangement for comparison of user performance during a real and a virtual 3-D peg-in-hole task. Tasks are performed using a unique six-degree-of-freedom (6-DOF) magnetic levitation haptic device. The arrangement allows a user to exert and experience real and virtual forces using the same 6-DOF device. During the virtual task, a peg and hole are rendered haptically, ...

OBJECTIVE To assess the feasibility of conducting a randomised controlled trial of a home-based virtual reality system for rehabilitation of the arm following stroke. DESIGN Two group feasibility randomised controlled trial of intervention versus usual care. SETTING Patients' homes. PARTICIPANTS Patients aged 18 or over, with residual arm dysfunction following stroke and no longer receivi...

Background Alzheimer’s disease (AD) not only effects the cognitive level, but also leads to significant decline in motor skill. Manual dexterity emerges with interaction of and processes is seen as an important predictor functional independence. The aim this study was compare manual people AD healthy older adults investigate effect level on dexterity. Method Nine Hole Peg Test (NHPT) used for a...

Government often dominates developing countries. Sometimes government is the only game in town. Countries suffer when rules of this game are deficient and governments are ineffective or predatory. Because this frequently seems to be the case, public sector institutional reforms have emerged as central to development. These reforms are an essential element of interventions by players like the Wo...

In this paper the modeling and simulation of a rectangular peg{in{hole insertion carried out by a six axis manipulator is presented. The dynamic model of the robot coupled with the assembly process model is established, where all possible contact points between the peg and the environment are monitored. Every occurring contact point represents a geometrical constraint on the robots dynamic whic...
