Two-handed gestures for human-computer interaction

The present thesis is concerned with the development and evaluation (in terms of accuracy and utility) of systems using hand postures and hand gestures for enhanced Human-Computer Interaction (HCI). In our case, these systems are based on vision techniques ...

MLP-based Log Spectral Energy Mapping for Robust Overlapping Speech Recognition

Hervé Bourlard, John David Scott Dines, Weifeng Li

This paper investigates a multilayer perceptron (MLP) based acoustic feature mapping to extract robust features for automatic speech recognition (ASR) of overlapping speech. The MLP is trained to learn the mapping from log mel filter bank energies (MFBEs) ...

Hand Posture Classification and Recognition using the Modified Census Transform

Sébastien Marcel, Yann Rodriguez, Agnès Just

Developing new techniques for human-computer interaction is very challenging. Vision-based techniques have the advantage of being unobtrusive and hands are a natural device that can be used for more intuitive interfaces. But in order to use hands for inter ...

Error handling in multimodal voice-enabled interfaces of tour-guide robots using graphical models

Plamen Prodanov

Mobile service robots are going to play an increasing role in the society of humans. Voice-enabled interaction with service robots becomes very important, if such robots are to be deployed in real-world environments and accepted by the vast majority of pot ...

Human-Brain Interface: Signal Processing and Machine Learning

Touradj Ebrahimi, Ulrich Hoffmann

The Electroencephalogram (EEG) is a recording of the electrical potentials generated by brain activity on the scalp. It has been used for decades as a non-invasive tool both in fundamental brain research and in clinical diagnosis. But it is now widely used ...

You Are Wrong!---Automatic Detection of Interaction Errors from Brain Waves

José del Rocio Millán Ruiz, Pierre Ferrez

Brain-computer interfaces, as any other interaction modality based on physiological signals and body channels (e.g., muscular activity, speech and gestures), are prone to errors in the recognition of subject's intent. In this paper we exploit a unique feat ...

The Role of Speech in Multimodal Human-Computer Interaction (Towards Reliable Rejection of Non-Keyword Input)

Hynek Hermansky

Natural audio-visual interface between human user and machine requires understanding of user's audio-visual commands. This does not necessarily require full speech and image recognition. It does require, just as the interaction with any working animal does ...
