This paper explores the viability of Magnetic Resonance Image (MRI) presentation on a computer screen. This includes investigating the feasibility of presenting the information on a desktop computer in a manner that facilitates MRI analysis and medical diagnosis. Two key objectives are identified: 1) understand the MRI analysis task and determine specific presentation issues and requirements th...

At Ordnance Survey, GB, we have taken an incremental approach to creating our 3D geospatial database. Research at Ordnance Survey has focused not only on methods for deriving 3D data, but also on the needs of the user in terms of the actual tasks they perform. This provides insights into the type and quality of the data required and how its quality is conveyed. In 2007, using task analysis and ...

The Continuum is a display-rich project room that allows distributed researchers to work together in intensive collaborative campaigns. In this paper, we describe iterative design study of using Continuum’s display technologies to support enhanced task parallelism and group awareness. The study involves placing small groups of users in two Continuum spaces connected over a high-speed network an...

Recent versions of international high-stakes tests like TOEFL and IELTS have made use of integrated tasks in addition to the traditional independent tasks in a claim to provide a more realistic estimation of the test takers’ language abilities. The present study aimed to investigate how test takers’ performance may differ on such tasks. As such, the test takers’ performance was compared on IELT...

planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. the problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...

This study set out to explore the impact of three levels of task planning on the accuracy of task-based oral performance with narrative task types among sixty Iranian sophomores majoring in Teaching English as a Foreign Language (TEFL) at Islamic Azad University – Tabriz Branch. It was hypothesized that simultaneous pre-task/on-line planning would lead to more accurate performance. To test the ...

Human work interaction design is an emerging discipline that aims to encourage empirical studies and conceptualizations of the interaction among humans, their variegated social contexts and the technology they use both within and across these contexts. In this paper the authors present a virtual reality system for visualization, navigation and reviewing of 3D CAD models within the oil industry ...
