We propose a novel low-cost method for quantitative assessment of upper extremity workspace envelope using Microsoft Kinect camera. In clinical environment there are currently no practical and cost-effective methods available to provide arm-function evaluation in three-dimensional space. In this paper we examine the accuracy of the proposed technique for workspace estimation using Kinect in com...

One of the weak aspects of the parallel robots is ratio between the workspace and the dimension of the mechanical structure, if compared with the serial one. Hence the shape of the workspace of a parallel manipulator is one of the most important aspects to reflect its working capacity. This paper introduces two innovative methods to analyze the workspace of some family of parallel robots, with ...

The workspace of a Stewart platform is a complex sixdimensional volume embedded in the Cartesian space defined by six pose parameters. Because of its large dimension and complex shape, such workspace is difficult to compute and represent, so that comprehension on its structure is being gained by studying its three-dimensional slices. While successful methods have been given to determine the con...

This paper presents a novel and exible architecture to support the collaboration paradigm for asynchronous sharing of computer-supported workspaces, or simply replayable workspaces. Such workspace, however, may be composed of multiple, interacting, tools. Through the capture, re-execution, and manipulation of a session with an interactive computer-supported workspace, it is possible to reuse th...

A neural network solution is proposed for solving path planning problems faced by mobile robots. The proposed network is a two-dimensional sheet of neurons forming a distributed representation of the robot's workspace. Lateral interconnections between neurons are "cooperative", so that the network exhibits oscillatory behaviour. These oscillations are used to generate solutions of Bellman's dyn...

Palantír is a configuration management workspace awareness tool that continuously informs developers of the changes that are made in parallel by other developers in other workspaces. In order to achieve its goal of reducing the number of merge conflicts when developers commit their artifacts, Palantír deliberately breaks traditional workspace isolation in order to promote better coordination of...

It has been suggested that the learning of new dynamics occurs in intrinsic coordinates. However, it has also been suggested that elements that encode hand velocity, and hence act in an extrinsic frame of reference, play a role in the acquisition of dynamics. To reconcile claims regarding the coordinate system involved in the representation of dynamics, we have used a procedure involving the tr...

Effortful cognitive performance is theoretically expected to depend on the formation of a global neuronal workspace. We tested specific predictions of workspace theory, using graph theoretical measures of network topology and physical distance of synchronization, in magnetoencephalographic data recorded from healthy adult volunteers (N = 13) during performance of a working memory task at severa...
