Un sistema de diálogo multimodal para jugar el juego de " Adivina la Carta " Abstract: In this paper a dialogue system with spoken Spanish and computer vision that plays the game " Guess the card " with members of the general public in a permanent stand of the science museum Universum at the National Autonomous University of Mexico (UNAM) is presented. The(More)
In this paper we present our work on the integration of human pointing gestures into a spoken dialog system in Spanish for conversational service robots. The dialog system is composed by a dialog manager, an interpreter that guides the spoken dialog and robot actions, in terms of user intentions and relevant environment stimuli associated to the current(More)
Previous evaluations of gesture recognition techniques have been focused on classification performance, while ignoring other relevant issues such as knowledge description, feature selection, error distribution and learning performance. In this paper, we present an empirical comparison of decision trees, neural networks and hidden Markov models for visual(More)
In this paper, we present the development of a tour–guide robot that conducts a poster session through spoken Spanish. The robot is able to navigate around its environment, visually identify informa-tional posters, and explain sections of the posters that users request via pointing gestures. We specify the task by means of dialogue models. A dialogue model(More)
