Adults on the autism spectrum commonly experience impairments in attention management that hinder many other cognitive functions necessary to appreciate relationships between sensory stimuli. As autistic individuals generally identify as visual learners, the effective use of visual aids can be critical in developing life skills. In this brief paper, we propose a Mobile Augmented Reality for Attention (MARA) application which addresses a lack of supportive and simple costeffective solutions for autistic adults to train attention management skills. We present the proposed design, configuration and implementation. Lastly, we discuss future directions for research.
