This article raises various issues in the design of an efficient BCI system in multimedia applications. The main focus is on one specific modality, namely an electroencephalography (EEG)-based BCI. In doing so, we provide an overview of the most recent pro ...
Brain-computer interface (BCI) systems allow the user to interact with a computer by merely thinking. Successful BCI operation depends on the continuous adaptation of the system to the user and on the user motivation. This paper presents a model of continu ...
This document presents a review on gestures for multi-modal interfaces and focus on hand gestures. It first introduces the role that the gesture modality plays in human communication. It then describes different types of gestures. Finally, it gives an over ...
Key to the design of human-machine gesture interface applications is the ability of the machine to quickly and efficiently identify and track the hand movements of its user. In a wearable computer system equipped with head-mounted cameras, this task is ext ...
Active mode locking of a Pr3+/Yb3+-doped upconversion fluoride fiber laser with an all-fiber ZnO acousto-optic phase modulator is demonstrated for the first time to the authors' knowledge. Optical pulses of similar to 550-ps duration with a repetition rate ...
In this paper we present a multi-modal web interface for autonomous mobile robots. The purpose of this interface is twofold. It serves as a tool for task supervision for the researcher and task specification for the end-user. The applications envisaged are ...
Data acquisition systems (DAS) are the basis for building monitoring tools that enable supervision of local and remote systems. Unfortunately, DASs are commonly based on proprietary technologies. The data format usually depends on the industrial process, t ...
Today, there is no standard system for performing maintenance on heterogeneous railway equipments. Maintenance staff needs a standard application capable of diagnosing and monitoring heterogeneous on-board equipments. We propose to build a web-based diagno ...
In this paper, we present different solutions for improving spline-based snakes. First, we demonstrate their minimum curvature interpolation property, and use it as an argument to get rid of the explicit smoothness constraint. We also propose a new externa ...
A unified approach for analysis of polarization fatigue and size effects on ferroelectric switching in relationship with injection and entrapment of charge at the interfacial layer of the ferroelectric film is developed. The proposed model suggests that an ...
