An empirical comparative evaluation of gestUI to include gesture-based interaction in user interfaces

Actualmente existen herramientas que soportan la personalizacion de gestos de los usuarios. En general, la inclusion de nuevos gestos implica escribir nuevas lineas de codigo que dependen en gran medida de la plataforma de destino donde se ejecuta el sistema. Para evitar esta dependencia de la plataforma, se propuso gestUI como un metodo basado en modelos que permite (i) la definicion de gestos personalizados basados ​​en el tacto, y (ii) la inclusion de la interaccion basada en gestos en las interfaces de usuario existentes en la computacion de escritorio plataformas El objetivo de este trabajo es comparar gestUI (un metodo MDD para tratar con gestos) versus un metodo centrado en el codigo para incluir la interaccion basada en gestos en las interfaces de usuario. Para realizar la comparacion, analizamos la usabilidad a traves de la efectividad, la eficiencia y la satisfaccion. La satisfaccion se puede medir utilizando la facilidad de uso percibida de los sujetos, Utilidad percibida e intencion de uso. El experimento fue llevado a cabo por 21 sujetos, que son ciencias informaticas M.Sc. y Ph.D. estudiantes Utilizamos un diseno cruzado, donde cada sujeto aplico ambos metodos para realizar el experimento. Los sujetos realizaron tareas relacionadas con la definicion de gestos personalizados y la modificacion del codigo fuente de la interfaz de usuario para incluir la interaccion basada en gestos. Los datos se recopilaron mediante cuestionarios y se analizaron mediante pruebas estadisticas no parametricas. Los resultados muestran que la gestUI es mas eficiente y efectiva. Ademas, los resultados concluyen que gestUI se percibe como mas facil de usar que el metodo centrado en el codigo. De acuerdo con estos resultados, gestUI es un metodo prometedor para definir gestos personalizados e incluir la interaccion basada en gestos en las interfaces de usuario existentes de los sistemas de software de computacion de escritorio.
