Resumen
Descripción
La búsqueda de información a través de la World Wide Web es una tarea común hoy en día. Sin embargo, es sobre todo una experiencia textual. Este trabajo propone e implementa un entorno 3D para la representación de los resultados de búsqueda Web en un entorno en tres dimensiones (3D) que es controlada por gestos y reconocimiento de voz. Con el fin de hacer eso, se requieren dos escenarios: una solución de servidor basado en Servicios Web XML que permite ser consumidos por los clientes que están buscando información en la Web; y una aplicación en cliente que permite ser ejecutado como una interfaz gráfica de usuario en el escritorio mediante el uso de comandos de voz y gestos. Esta última aplicación se encarga de modelar gráficamente el entorno 3D de acuerdo con los resultados de búsqueda Web.Un prototipo del sistema propuesto fue implementado, lo que representa un conjunto de resultados de búsqueda Web en un entorno 3D. El escenario 3D es manejada por gestos y comandos de voz; el entorno 3D se basa en la administración de algunas transformaciones 3D tales como la rotación y el escalado de las caras interiores de un toroide.Una evaluación del prototipo en contextos de búsqueda sugiere que hay un alto nivel de aceptación del usuario del modelo multimedia propuesto. Las personas que probaron el prototipo han dicho que tiene una interfaz gráfica de usuario intuitiva, y que tanto el habla como el reconocimiento de gestos han sido una alternativa altamente funcional para las tareas relacionadas con la búsqueda Web. Sin embargo, hay algunos aspectos a mejorar, sobre todo en el apoyo de reconocimiento de voz de diferentes acentos. En general, el prototipo multimedia cumplió con las expectativas de una muestra de los usuarios finales, lo que demuestra que este tipo de interfaces tienen un gran potencial.
Searching for information through the World Wide Web is a common task nowadays. However, it is mostly a textual experience. This work proposes and implements a 3D environment for representing Web search results in a three-dimensional (3D) environment that is controlled by gestures and speech recognition. In order to do that, two scenarios are required: a server-side solution based on XML Web Services that allows being consumed by clients that are searching information on the Web; and one client-side application that allows being executed as a graphic user interface in desktop by using speech and gesture commands. This latter application is in charge of graphically modeling the 3D environment according to the Web search results.A prototype of the proposed system, which represents a set of Web search results in a 3D environment, was implemented. The 3D scenario is handled by gestures and voice commands; the 3D environment is based on the management of some 3D transformations such as rotation and scaling of the inner faces of a torus.An evaluation of the prototype in search contexts suggests that there is a high level of user acceptance of the proposed multimedia model. Testers have said that the prototype has an intuitive graphical user interface, and that both speech and gesture recognition have been a highly functional alternative for tasks related with Web searching. Still, there are some aspects to improve, especially in the speech recognition support of different accents. Overall, the multimedia prototype met the expectations from a sample of end users, showing that such interfaces have great potential.
