Concepção de um software de geometria interativa utilizando interfaces gestuais para dispositivos móveis

Abstract in Portuguese
Os softwares de Geometria Interativa (GI) foram desenvolvidos com o objetivo de possibilitar aos estudantes explorarem a geometria por meio do computador, permitindo a construção e manipulação de objetos geométricos, como retas, pontos e circunferências. Por meio da interface destes softwares, os estudantes são capazes de compreender e manipular os objetos geométricos, podendo influenciar na aprendizagem da geometria. Para Laborde (2007), os desenvolvedores de softwares de GI deveriam se preocupar com os aspectos pedagógicos e com o design da interface, pois, as interfaces indevidamente projetadas podem causar frustrações aos alunos, fazendo com que sintam dificuldade em utilizar o software e terminando por não direcionar o aprendizado da geometria. Apesar desta importância, há poucos estudos que investigam metodologias que relacionam os conceitos pedagógicos e os recursos computacionais. Além disto, há uma carência de pesquisas sobre diferentes tipos de interações disponíveis para a criação de interfaces para softwares de GI. A fim de preencher esta lacuna, este trabalho de mestrado tem como objetivo investigar metodologias para o desenvolvimento de gestos para interfaces gestuais em softwares de GI. É proposto um novo tipo de interação para estes softwares, com o objetivo de apoiar a aprendizagem da geometria por meio das interfaces gestuais.

Abstract in English
The Interactive Geometry software (IG) were developed with the goal of enabling students to explore geometry through the computer, allowing the construction and manipulation of geometric objects, such as, lines, dots and circles. Through these interfaces software, students are able to understand and manipulate geometric objects, and may influence their learning of geometry. To Laborde (2007) , IG developers should worry about the pedagogic aspects and the design of the interface, because the improperly designed interfaces can make students to become frustrated, making them feel difficult to use the software and not focusing in the learning of geometry itself. Despite this importance, there are few studies investigating the pedagogical methodologies that relate concepts and computational resources. Furthermore, there is a lack of research about different types of interactions available for creating interfaces for IG software. In order to fill this gap, this master thesis aims to investigate methodologies for the development of gestures for gestural interfaces in GI software. It is proposed a new type of interaction for these software, aiming to support the learning of geometry.
