Recent advances in remote experimentation

Abstract: Discusses challenges in meeting quality of service (QoS) requirements in a flexible learning context where students carry out hands-on sessions of remote experimentation on a physical system via the Internet. Novel solutions are developed to overcome the current lack of predictability of the Internet so that QoS can be improved via content adaptation to the available bandwidth. An augmented-reality approach is used to enhance the user perception of the remote system, and a unique simulation-based scheme is proposed to recover from packet losses. The approach is illustrated through the remote control of an inverted pendulum.

Remote Experimentation: Improving User Perception Using Augmented Reality

Abstract: The possibility to conduct live experiments on real setups is a key pedagogical element which enablesteachers to give life to the subject matter. In order to avoid moving the experimental setup in theclassroom, or to overcome the difficulties of accessing laboratory facilities at any time, it is useful toprovide an interactive and remote access to such facilities. A good quality for the visual feedbackprovided to the user is a key to enhance the user perception of the remote system. A multiplatformclient-server solution based on personal computers, which share information through the Internet, hasbeen designed to serve this paradigm. LabVIEW is the ideal candidate to provide the interoperabilityand the advanced tools required for both the communication and visualization purposes.

A new approach in the use of multimedia for technology enhanced learning

Abstract: The authors describe ongoing work in the Electrical and Computer Engineering Department at the University of Florida as we offer an Online MS degree in Electrical Engineering and as we proceed with the development of major components of a BS degree in Electrical Engineering. In particular, we describe the implementation of the "lectures on demand" method using multimedia streaming technologies within the now widely accepted Asynchronous Learning Network (ALN) model. Each class in the program is delivered on campus via the traditional face to face lecture mode. However, the classes make explicit use of computer and communication technology to facilitate an asynchronous mode of learning for both on-campus as well as distance education students. The lecture and in-class interactions including computer demonstrations are captured as video or computer animations. This digital video is compressed and broadcast 'live' via the Internet so that students who cannot attend the class can join the lecture. After the class, a student assistant is engaged to generate high quality image and graphical copy of material developed spontaneously in the class by the instructor. These are then integrated with class notes into a synchronized multimedia presentation.

1. An Architecture for Sustainable Interaction in Teleoperation over the Internet with Application to Remote Control of an Inverted Pendulum

Abstract: This paper discusses challenges in enabling teleoperation over the Internet for the specific case of real systems which exhibit fast dynamics. A distributed client-server architecture is proposed to provide the necessary level of interactivity for supervision and tuning, without compromising the essential control tasks. Enabling features include realtime simulation and augmented-reality visualization to enhance the user perception of the distant ongoing operations. The proposed approach is illustrated through the remote control of an inverted pendulum.
