To improve the quality of research, it is necessary to understand the obstacles to undertaking research. This study aimed to identify: I) internal obstacles to research as considered by faculty members at Shiraz University of Medical Sciences; ii) differences between their viewpoints by gender and professional variables; and iii) the effect of these obstacles on research activity. Six types of ...

In this work we propose a wearable solution for boundary detection (using ultrasonic range finders) and notification (via tactile actuators) under conditions of poor visibility. “Personal Radar” is not ’yet another’ belt-like tactile feedback system used for walking navigation, the unique feature of our obstacle scanning and notification solution is, that it is self-contained and fully self-gov...

The current study set out to evaluate how individuals walk through apertures created by different stationary obstacles. Specifically, we examined whether the passability of apertures differed between human and pole obstacles by quantifying aperture crossing behaviors such as the critical point. Participants walked an 8m path toward a visible goal located at the end. Two obstacles were positione...

Personal Learning Environments (PLEs) hold the potential to address the needs of informal learners for multi-sourced content and easily customisable learning environments. This paper presents the lessons learned from a case study regarding the use of widget-based PLEs by informal learners for finding and evaluating Open Educational Resources (OER). The lessons learned from this case study have ...

In this paper, we describe the Cye personal robot, concentrating on its path planning and navigation. We start out with a brief description of the general problem, followed by more detail on the Cye robot. After that, we concentrate on the path planner, which uses a global potential field approach, combined with a novel optimization criterion. This ensures that the robot maintains adequate dist...
