An Omnidirectional System for Navigation in Virtual Environments

Part 8: Robotics and ManufacturingInternational audienceVirtual Reality (VR) is one of the newest technological domains with revolutionary applicability for the tomorrow’s Future Internet, including visions of the Internet of Things. The sensation of total immersion in Virtual Environment (VE) is still unresolved. Therefore, our work proposes a new omnidirectional locomotion interface for navigation in VEs. The novel interface was built from an ordinary unidirectional treadmill, a new mechanical device, a motion capturing system to track the human walking and a control method using artificial intelligence techniques. A neural network is used to predict the motion of the new interface based on user’s body motion and information about VE. The feasibility of the proposed system is verified through experiments and the preliminary results suggest that the new interface performs very well in a simplest VE based on our control method

Evaluation of a P300-Based Interface for Smart Home Control

Part 7: Smart SystemsInternational audienceThis paper evaluates a hybrid neurophysiological interface for controlling a virtual smart home. Electrooculography (EOG) and Electroencephalography (EEG) techniques are used for recording biosignals from the user’s body. The signals are further analyzed and translated into commands for controlling a virtual smart home. The purpose of the study was the evaluation of the implemented interface and the rejection of a set of possible erroneous commands generated by the interface. From a main menu the user is able to select a mask that will reveal a second menu with supplementary commands. The user has the option to cancel the propagation of an erroneous selected mask in the system by selecting another item from the main menu

Control Interfaces for a Collaborative System Using LabView Package

Part 2: Collaborative SystemsInternational audienceIn-robotics functions, performed by the software, include data acquisition, motor control, sensor signals processing, perception of objects and navigation through environment. LabView provides a solution to the limited skills and the limited time problem that appears when we use programming environments like C++ or Java. This document introduces the implementation of a communicative mobile robotic system that is based on two collaborative Pioneer robots controlled by user friendly interfaces developed in LabView. The purpose of developing this type of interfaces was to allow a complex collaborative system to adapt to any platform and be used by any type of user, without depending on his robotics knowledge level
