This paper investigates approaches capable of inducing sensations of tele-presence in robotic tele-operations. Operator's control actions are simpler, if he feels being in the remote environment. The goal is to replicate some conditions of the remote environment to let operator's perception behaviours approximate to the natural ones. Since immersion aims at providing stimulus to trick the sensory...
Human-machine interfaces play a crucial role in intervention robotic systems operated in hazardous environments, such as deep sea conditions. This article introduces a user interface abstraction layer to enhance reconfigurability. It also describes a VR-based interface that utilizes immersive technologies to reduce user faults and mental fatigue. The goal is to show the user only the most relevant...
Recent advances in Unmanned Aerial Vehicles (UAVs) have enabled a myriad of new applications many of which provide aerial vision-based sensing. In intrusion detection or target tracking applications, it is important to reach a given area of interest in the shortest time, and create an online data streaming connection to a monitoring station for immediate delivery of content to the operator. However,...
This paper proposes a new interaction mechanism for tele-operating a mobile robot. The approach explores the notion of telepresence and physical embodiment to create what may be called tele-embodiment. Its principle is that the operator will see himself at the remote site and this will enable him/her to better operate the robot. Four interaction styles were experimentally compared, from the traditional...
Video applications, which include industrial uses like machine vision, object tracking, surveillance, driving aids, etc. are becoming increasingly common. These sensors produce large amounts of data, being normally compressed at the source nodes to save network bandwidth. As a side effect, video streams exhibit a large variability in their bandwidth utilization. On the other hand, many video applications...
The Service-Oriented (SO) paradigm has been widely adopted in the development of distributed applications in open and complex environments due to its inherent flexibility, modularity, ease of code reuse and deployment, among other properties. According to this paradigm, different functionalities are encapsulated in services, which are self-contained re-locatable software entities that can be discovered...
