  The brain's attention system is a complex and adaptive network of brain
regions that enables individuals to interact effectively with their
surroundings and perform complex tasks. This system involves the coordination
of various brain regions, including the prefrontal cortex and the parietal
lobes, to process and prioritize sensory information, manage tasks, and
maintain focus. In this study, we investigate the intricate mechanisms
underpinning the brain's attention system, followed by an exploration within
the context of augmented reality (AR) settings. AR emerges as a viable
technological intervention to address the multifaceted challenges faced by
individuals with Attention Deficit Hyperactivity Disorder (ADHD). Given that
the primary characteristics of ADHD include difficulties related to
inattention, hyperactivity, and impulsivity, AR offers tailor-made solutions
specifically designed to mitigate these challenges and enhance cognitive
functioning. On the other hand, if these ADHD-related issues are not adequately
addressed, it could lead to a worsening of their condition in AR. This
underscores the importance of employing effective interventions such as AR to
support individuals with ADHD in managing their symptoms. We examine the
attentional mechanisms within AR environments and the sensory processing
dynamics prevalent among the ADHD population. Our objective is to
comprehensively address the attentional needs of this population in AR settings
and offer a framework for designing cognitively accessible AR applications.
