There is a large variation in the degree of difficulty among these individuals and it is critically important to develop customized therapies and materials for them. In general, the technologies for this audience don’t offer means of customization to meet the needs of each individual. In this paper, we discuss how to present to the therapists a different technology than they are used to finding or using in professional practice. This technology is one designed to offer them autonomy in creating activities for the public with autism. Its design follows a different design perspective than is usually adopted for this audience, namely a combination of Meta Design, Design Probes and Semiotics Engineering. The discussion of how to introduce the technology for its intended users is important for formative evaluation steps along the interaction design process.

These devices also have the possibility of including additional information and performing naturally non-immersive tasks. This work presents a 3D interaction tablet-based tool, which allows the aggregation of all major 3D interaction tasks, such as navigation, selection, manipulation, system control and symbolic input. This tool is for generalpurpose systems, as well as, engineering applications. Generally this kind of application uses specific interaction devices with four or more degrees of freedom and a common keyboard and mouse for tasks that are naturally non-immersive, such as symbolic input (e.g., text or number input). This article proposes a new tablet-based device that can perform all these major tasks in an immersive environment. It also presents a study case of the use of the device and some user tests.

Besides the use of keyboard and mouse, best suited for desktop environments, other devices emerged for specific use in immersive environments. The lack of standardization in the use and in the control mapping of these devices makes the design task more challenging. We performed an exploratory study involving beginners and advanced users in the use of three devices in 3D environments: Keyboard-Mouse, Wiimote and Flystick. The navigation in this kind of environment is done through three tools: Fly, Examine and Walk. The study results showed how the interaction in virtual reality environments is affected by the navigation mechanism, the device, and the user's previous experience. The results may be used to inform the future design of virtual reality environments.

Esse artigo apresenta o desenvolvimento e a avaliação de um jogo colaborativo chamado ComFiM, para interfaces móveis tangíveis. O jogo foi desenvolvido com base nos requisitos de um grupo de crianças com autismo, visando estimular a comunicação por meio de estratégias colaborativas. O ComFiM foi elaborado para interação entre pares de usuários. Cada usuário possui um tablet para compartilhar recursos no jogo e uma TV funciona como um lugar comum entre os usuários. O ComFiM foi avaliado conforme aspectos relacionados ao interesse dos usuários na tecnologia, à percepção de cada usuário do seu interlocutor e de intenções de comunicação observadas entre os usuários para colaborarem entre si. Os testes ocorreram em um período de 6 semanas, com 4 crianças com autismo. Os resultados indicam que o ambiente colaborativo proporcionado pela tecnologia utilizada, bem como as ...
