Cognitive rehabilitation, which uses software applications (multimedia), advanced physical devices (PDAs, cellular phones, etc.) or virtual reality applications, presents limitations of several types related to: workspace, realistic representation, intuitive interaction, dexterity demand, availability, devices dependency, user-friendly interface, customization, multi-sensory input/output, complexity, etc. Recently, the technological evolution has allowed the development of artifacts based on augmented reality that overcome most of the weaknesses of the applications implemented with the previous technology. In this way, this paper presents and discusses the development of an interactive artifact based on augmented reality, which makes possible intuitive tangible interactions, multi-sensory feedback, customization, simplicity and the implementation of cognitive exercises. Ten users evaluated cognitive applications running over the interactive artifact under the point-of-view of augmented reality, giving their impressions. Finally, we discuss the potential of the interactive artifact, pointing out directions to improve its structure and utilization by cognitive disabled people.
This chapter introduces virtual reality and augmented reality as a basis for simulation visualization. It shows how these technologies can support simulation visualization and gives important considerations about the use of simulation in virtual and augmented reality environments. Hardware and software features, as well as user interface and examples related to simulation, using and supporting virtual reality and augmented reality, are discussed, stressing their benefits and disadvantages. The chapter intends to discuss virtual and augmented reality in the context of simulation, emphasizing the visualization of data and behavior of systems. The importance of simulation to give dynamic and realistic behaviors to virtual and augmented reality is also pointed out. The work indicates that understanding the integrated use of virtual reality and simulation should create better conditions to the development of innovative simulation environments as well as to the improvement of virtual and augmented reality environments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
