Since the emergence of virtual reality (VR) technologies, many researchers have argued on the benefits of their use for people with intellectual and multiple disabilities. However, up to this date there is not a single study that presents a detailed overview of the state of the art in virtual reality as a support tool for the treatment of people with intellectual and multiple disabilities, as well as Autism and Down Syndrome. The aim of this study is to provide a detailed overview of the state of the art in the virtual reality area focusing on people with multiple disabilities, that encompasses intellectual and physical disabilities. There is still no consensus on the effectiveness of VR-based treatments. Virtual reality can offer rich environment and features, but most of the researches focuses only in the experience to be inside a virtual place without taking advantage of what benefits VR provide us. Furthermore, most of our selected studies used non-immersive VR and AR. Thus, immersive VR is an open field with many opportunities to be explored. We believe VR has great potential to be effective in the treatment of people with intellectual and multiple disabilities.

Abstract. This paper presents a tool to aid teaching of calculus for undergraduate courses using Augmented Reality. It is a quadric surface viewing application for Android platform that displays six quadric surfaces. The tools and techniques used in the development and the evaluation results of the tool by the academic community will also be presented.Resumo. Este artigo apresenta uma ferramenta de apoio ao ensino da disciplina de Cálculo para os cursos de graduação utilizando Realidade Aumentada. Trata-se de um aplicativo de visualização de superfícies quádricas para a plataforma Android onde são exibidas seis superfícies quádricas. Serão apontadas também as ferramentas e técnicas aplicadas em seu desenvolvimento além dos resultados da avaliação da aplicação pela comunidade acadêmica.

Abstract. This study investigated the efficacy of a virtual reality-based cognitive and motor coordination training for people with intellectual and multiple disabilities, focusing on community participation. Ten people with disabilities were selected from an institutional care for people with disabilities and they were enrolled in a five-week experiment, which consisted in shopping in a virtual reality supermarket. The results show that the patients demonstrated statistically significant improvements regarding the task gave, also based on the observational analysis of the instructor and physiotherapist. Thus, the analysis indicates that the VR-based method can be effective in the cognitive development of those patients, improving their social inclusion and cognitive skills.

This study investigated the potential of using a virtual reality-based motor coordination and cognitivetraining for people with intellectual and multiple disabilities, focusing on their autonomy and communityparticipation. A low-cost innovative interaction interface between the user and the virtual environment wasproposed to provide a more realistic and intuitive interaction experience. Nine people with disabilities wereselected from an institutional care for people with disabilities and they were enrolled in a four-week experiment,which consisted in going through three challenges. The results show that the patients demonstrated statisticallysignificant improvements regarding the task gave, also based on the observational analysis of the instructorand physiotherapist. Thus, the analysis indicates that the VR-based method can be effective in the motordevelopment of those patients, improving their autonomy and cognitive skills.

Resumo Este artigo apresenta uma ferramenta de apoio ao ensino de física utilizando Realidade Aumentada. Os principais conceitos sobre Realidade Aumentada e os frameworks da área serão apresentados. As funções que simulam os eventos físicos serão explicadas e desenvolvidas. Neste trabalho nenhuma biblioteca clássica de simulação física foi utilizada. A ferramenta foi dividida em vários módulos da física e, para cada um destes módulos, um sistema baseado em Realidade Aumentada foi proposto. A proposta central deste trabalho é mostrar que ferramentas baseadas em Realidade Aumentada podem potencialmente tornar o estudo de física mais lúdico e interessante.
