Item Interior Design Tool for Common Users(The Eurographics Association, 2021) Ferreira, Alfredo; Medeiros, Roberto; Barreto, Rui; Fonseca, Manuel J.; Jorge, Joaquim A.; Chambel, Teresa and Nunes, Nuno and Romao, Teresa and Creissac Campos, JoséUntil recently, computer simulation of interior decoration was reserved to architects and other highly skilled professionals, because existing tools require technical knowledge on computer aided design. During the last years, several easy-to-use tools for home planning and interior design have been released. These tools intend to allow users, without specific skills, to create their virtual house, decorate it and navigate in the resulting scenery. In this paper we present three of these applications and describe task analysis using them. As a result of this experiment, we identify user requirements for this kind of tools, along with positive and negative aspects, providing good insights and directions for future work.Item Multi-Modal Painter: Pintar Usando as Mãos e Fala(The Eurographics Association, 2021) Cerejo, Mariana; Santos, José; Ferreira, Alfredo; Fonseca, Manuel J.; Jorge, Joaquim A.; Chambel, Teresa and Nunes, Nuno and Romao, Teresa and Creissac Campos, JoséNos últimos anos várias equipas de investigação têm vindo a desenvolver um novo paradigma de interacção entre humanos e computadores, procurando reduzir ou eliminar totalmente a necessidade de manuseamento de dispositivos físicos para controlar a máquina. O trabalho aqui apresentado foca a integração de reconhecimento de gestos e fala para controlo de aplicações. Para validarmos esta integração desenvolvemos uma aplicação multi-modal que consiste numa ferramenta de desenho 2D. Com esta aplicação o utilizador pode desenhar e pintar utilizando apenas gestos e comandos de fala.
