“…Hence, the term "natural environment" is described, for clarification purposes regarding the presented research, as a low-density constructed urban area rich in trees, flora, and vegetation. Also, the innovative concept "visual-spatial compound linear geometries" is defined as a set of line structures in a parallel or perpendicular relationship to each other (called sometimes in computer vision bibliography as PnP / "Perspective-n-Point" linear geometries; Providing an excellent pose estimation functionality in robots/computer vision) [1,[23][24][25].…”

“…Their movements look clumsy, and they often make mistakes. DCD is usually diagnosed in children between ages 5-8, and it affects one (1) in every twenty (20) children. That means, on average, one child in every school class may have DCDso it might even affect someone you know.…”

“…DCD disorder is a (mind-based) visual-spatial motor coordination problem, like (sensor-based) robot pose self-determination in computer vision [23][24][25], and (eye-based) visual avian navigation and nest nidification georeferencing in birds' migration [1]. While the fundamental concepts behind robot pose estimation and birds' navigation and nidification are "spatial cognition" and particularly the observed "visual-spatial compound linear geometries", they are not considered so far in the DCD bibliography.…”

“…The basic idea behind this research paper comes from a recent paper on the influence of spatial compound linear geometries, usually found in low-density urban environments, on birds' visual avian navigation and nest nidification [1]. Should these "visual-spatial compound linear geometries" improve as cognitive landmarks the human spatial cognition and walking physiology?…”

“…In each case, the "visual-spatial compound linear geometries" (i.e. shapes and mutually detect parallel or perpendicular line pairs in observed linear or rectangular image-geometries), that normally occur in low-density urban environments, should be regarded as auxiliary georeferencing, coordination, and navigation tool [1].…”

Problem: Awareness of children, who experience movement, particularly motor coordination difficulties, has increased dramatically over the last ten years. These motor coordination problems of children with Developmental Coordination Disorder (DCD) or/and Attention-Deficit / Hyperactivity Disorder (ADHD) have been frequently associated with poor visual and spatial eye-vision processing. Background: Motor control difficulties for DCD and ADHD children have been discussed in detail. However, just a little is known about the influence of the natural environment on these disorders. Even more, the built environment’s impact as a spatial cognition and coordination functionality has never been considered. Aim: This pilot and innovative study aim to identify the correlation between and evaluate the visual contribution of the so-called “spatial compound linear geometries” and DCD children’s motor/walking control. Methodology: Twenty children aged 5 to 8 years with DCD difficulties (two intervention groups, one with 10 boys and the other one with 10 girls) were assessed by a statistical structural evaluation in three built environments (two urban parks and one pocket park), under two conditions (rich or not in trees, flora, and PnP linear geometries), and different motor coordination control situations (static balance, dynamic balances, dark condition). Results: The worst performances (regarding movement disorders and motor coordination problems) were observed for both groups with DCD children playing in parks poor in or without trees, flora, and spatial compound linear geometries. Instead, a significant performance (strong statistical correlation) was found for the same intervention group (DCD children’s boys or girls) playing in parks rich in trees, flora, and vegetation (natural environment). The best performance (very strong statistical correlation) was detected in parks rich in a natural environment and linear geometries. Conclusions: While the natural environment contribution is bibliographically known, the best performance finding of the visual contribution of the spatial compound linear geometries, as spatial landmarks enriching the visual-spatial motor/walking functionalities for Children with DCD disorder, could provide new cognitive approaches towards an understanding of children’s Developmental Coordination Disorder and walking physiology. DCD children’s performance, scores, and cues were related to both the natural environment and the spatial compound linear geometries as spatial landmark motor coordination cues and spatio-temporal clues. The significant variability in sensory processing among children with DCD, ADHD, and co-occurring symptoms can contribute to understanding how neurological and social factors correlate across diagnoses. Also, derived observations for stepping errors, Gait analysis (variables), and spatio-temporal clues conclude that visual eye-based processing interrelates with motor coordination problems, performance, inattention, environmental conditions (dark), sex identity (boys, girls), and DCD hyperactivity. Applications: Development of interactive visual applications for (i) human spatial cognition and movement improvement; and (ii) children’s motor control and coordination refinement.

Background. Working memory-based spatial cognition has attracted the attention of the scientific community in navigation and reorientation projects. The dominant approach considers that spontaneous spatial navigation behavior is based merely on environmental geometry (built and natural environmental objects). In this domain, DCD (Developmental Coordination Disorder) motor skill orientation problems have been frequently associated with poor visuospatial cognition, while immersive VR environments encourage more repetition, allowing for faster motor skill development and recovery. Objective. This pilot study tested the functionality of an immersive VR environment with environmental geometry (rectangular arena rich in symmetry) and featural landmark cues (striped wall, flora) as a route-learning tool for children with motor skill disorders. Methods. Forty DCD children aged 5 to 8 years (20 boys and 20 girls); five (5) 3D reality modeling setups with orthogonality, symmetry, and striped walls as design parameters; and trial walk-through coordination exercises using a predefined visual pathway with different motor control conditions (daylight, darkness). Participants’ path completion rate, path completion time, and walk-through satisfaction were recorded as route-learning performance variables and analyzed statistically. Results/findings. DCD children’s spatial orientation was statistically shown to be more stable and robust (in path completion rates, termination time, and walk-through level of satisfaction) in a virtual 3D environment rich in orthogonality, symmetry, and featural cues as landmarks. In this compound environmental geometry setup, training functionality and immersive learning performance enjoyed an 8.16% better path completion rate, a 12.37% reduction in path completion time, and 32.10% more walk-through satisfaction than reality modeling setups poor in geometry and landmarks. The effectiveness and robustness were validated statistically. Conclusion. Children with motor skill difficulties train and learn better in virtual 3D environments that are rich in orthogonality, symmetry, and featural landmark cues.
