Development of an interactive artifact for cognitive rehabilitation based on augmented reality

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.
