- Separating gesture detection and application control concerns with a multimodal architecturePublication . Morgado, Leonel; Cardoso, Bernardo; Carvalho, Fausto de; Fernandes, Luís; Paredes, Hugo; Barbosa, Luís; Fonseca, Benjamim; Martins, Paulo; Nunes, Ricardo RodriguesGesture-controlled applications typically are tied to specific gestures, and also tied to specific recognition methods and specific gesture-detection devices. We propose a concernseparation architecture, which mediates the following concerns: gesture acquisition; gesture recognition; and gestural control. It enables application developers to respond to gesture-independent commands, recognized using plug-in gesture-recognition modules that process gesture data via both device-dependent and deviceindependent data formats and callbacks. Its feasibility is demonstrated with a sample implementation.
- Bringing user experience empirical data to gesture-control and somatic interaction in virtual reality videogames: an exploratory study with a multimodal interaction prototypePublication . Fernandes, Luís; Nunes, Ricardo Rodrigues; Matos, Gonçalo; Azevedo, Diogo; Pedrosa, Daniela; Morgado, Leonel; Paredes, Hugo; Barbosa, Luís; Fonseca, Benjamim; Martins, Paulo; Cardoso, Bernardo; Carvalho, Fausto deWith the emergence of new low-cost gestural interaction devices various studies have been developed on multi-modal human-computer interaction to improve user experience. We present an exploratory study which analysed the user experience with a multimodal interaction game prototype. As a result, we propose a set of preliminary recommendations for combined use of such devices and present implications for advancing the multimodal field in human-computer interaction.
- Primeira armada da Índia: novo conceito de jogo misturando realidades aumentada e virtual, gestos finos e amplosPublication . Morgado, Leonel; Cristóvão, Paulo; Fernandes, Luís; Nunes, Ricardo Rodrigues; Martins, Paulo; Paredes, Hugo; Barbosa, Luís; Cardoso, Bernardo; Carvalho, Fausto deApresentamos um conceito de jogo inovador e o seu protótipo inicial, integrando tipos distintos de interação e de visualização. Dois jogadores interagem como timoneiro de uma nau portuguesa e gigante Adamastor. Um joga em realidade virtual controlada por gestos finos, outro usa aumentação contextual com gestos amplos e fi-nos. Pretende o conceito e o protótipo servirem como exemplificadores das potencialidades das novas formas de interação e de como as concretizar.
