In recent years a number of neuroprostheses have been developed and used to assist stroke and spinal cord injured subjects to restore or improve grasping function. These neuroprostheses clearly demonstrated that the targeted group of subjects can significantly benefit from this technology and that functional electrical stimulation (FES) is a viable ...

When hand meets object, we confront the overlapping worlds of sensorimotor and cognitive functions. We reach for objects, grasp and lift them, manipulate them, and use them to act on other objects. Prehension under visual guidance entails two motor processes: ‘reaching’ and ‘grasping.’ Reaching refers to the extension of the arm to touch a distant ...

In the present study we attempted to determine the nature of the visual analysis that is performed on an object in order to grasp it. We required eight healthy subjects to reach and grasp a wooden bar which was superimposed over the shaft of the Müller-Lyer illusion. Vision of both the hand and the bar was allowed. Three different bar lengths were used.

DC-GRASP: directing the search on continuous-GRASP
Journal of Heuristics, 2015Several papers in the scientific literature use metaheuristics to solve continuous global optimization. To perform this task, some metaheuristics originally proposed for solving combinatorial optimization problems, such as Greedy Randomized Adaptive Search Procedure (GRASP), Tabu Search and Simulated Annealing, among others, have been adapted to solve ...

Interpretation of grasp and manipulation based on grasping surfaces
Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003A method is proposed to classify and describe grasping and manipulation. It is based on the three functions of grasping surfaces, namely object-supporting, pressing and wrapping functions. The method provides a simple description for grasping and manipulation and it can express their physical fundamentals. The description is illustrated through example

The reach-to-grasp movement is a prototype of human movement coordination. Since the pioneering work of Jeannerod (Attention and performance, ix. Erlbaum, Hillsdale, NJ, pp 153-169, 1981), this movement is generally considered to be a coordinated combination of hand transport and grip formation.

When you look for your copy of TICS among the mail in your mailbox, your visual-attentional mechanisms marshal saccadic eye movements to search for specific attributes: a glossy cover, a colored spine, etc. In other words, when you know what you're searching for beforehand, visual selective attention uses information about the searched-for object to ...

The GRASP mission has been studied by ESA as a candidate mission in Gamma-Ray Astronomy with Spectroscopy and Positioning. The key feature of the mission will be a high-resolution, Ge-based spectrometer, allowing for a resolution of the keV order ∼1 MeV, and a CsI imager, permitting source location accuracies approaching the arcminute over a wide field
