Designing usable real-time, distributed collaboration tools is a complex but important task. Workspace awareness can potentially help in making realtime, distributed collaboration tools more usable through a communication of who is in the shared workspace and what they are doing. We present qualitative evaluations of the workspace awareness features of a gesturebased diagramming tool, Distribut...

This paper describes our design and implementation of an augmented table interface for small group meetings. The system was designed to be used by multiple users in the ubiquitous environment, where people do not need to bring their laptop PCs. With effective use of the advantage of computer vision, we implemented the concept of ubiquitous desktop as personal workspace and virtual Chinese table...

This paper presents a new discretization method for the computation of the orientation workspace of 6DOF parallel manipulators, de®ned as the set of all attainable orientations of the mobile platform about a ®xed point. The method is based on the use of a modi®ed set of Euler angles and a particular representation of the orientation workspace. In addition, the projected orientation workspace is...

In this paper, we propose an application programming interface (API) for designing of a robot workspace. The interface is realized inside a SolidWorks computer aided design environment. Via API, the builder of the robot system can check if: a) the current robot mechanism can perform the desired work movements, b) the robot can avoid singularity, and c) the points of the robot trajectory are wit...

An office ergonomics intervention incorporating a macroergonomics design approach was conducted to investigate the effects of a flexible workspace design and ergonomics training on musculoskeletal health, psychosocial environment and performance in a computer-based office setting. This longitudinal, field intervention study included three data collection periods (one preand two post-interventio...

Magnetic Continuum Robots In article number 2000211, Niandong Jiao, Lianqing Liu, and co-workers propose a method of steering miniaturized flexible magnetic continuum robot in the enlarged workspace electromagnetic navigation system. This can greatly enlarge effective workspace, aims to expand application for retrograde intrarenal surgery.

We present a fast algorithm for solving the problem of determining if the straight line between two different postures of a parallel manipulator lie fully inside its workspace. This algorithm is based on the analysis of the algebraic inequalities describing the constraints on the workspace (link lengths range, mechanical limits on the joints, interference between the links) and enables to compu...

This paper describes our design and implementation of an augmented table system for face-to-face meetings. The system was designed to be used by multiple users in the ubiquitous environment, where people do not need to bring their laptop PCs. With effective use of the advantage of computer vision, we implemented the concept of ubiquitous desktop as personal workspace and virtual Chinese table a...

One of the main advantages of the Gantry-Tau machine is a large accessible workspace/footprint ratio compared to many other parallel machines. The design presented in this paper achieves a workspace/footprint ratio of more than 2.7 with fixed length links, which is high for a PKM. Typical PKMs, for example the Delta robot, has a ratio less than one. Optimisation schemes are typically used in or...
