The Use of Multimodal Interaction for Supporting the Production of Location-Based Information

Despite the increasingly volume of location-based information systems, it is a common practice to develop these technological resources aiming for the usage by professional content providers. Non-experts users appear as an important alternative of impartial contributions in this scenario. In this manner, multimodal interaction - particularly, gestures recognition and voice commands - can open further opportunities for support the usage by common users. This paper therefore aims to analyze the contributions on the use of multimodal interaction for supporting the production of location-based information. Its research methodology is based on a conceptual framework as well as usability analysis with real users. The results revealed that non-experts users often take a while before becoming confident with new kinds of interaction. It also shown that voice commands were rather more useful than gestures according to the users. Furthermore, even with long years of research in the field, technological resources still need improvements for the speech and gesture recognitions, mainly due to the idiosyncrasies presented on this interaction. Although additional research is still necessary in this area, it can be concluded that multimodal interactions have a great potential for supporting the production of location-based information.
