Autistic individuals often exhibit superior local visual sensitivity but may struggle with global processing, affecting their visuomotor integration (VMI). Goal-directed overhand throwing is common in both the physical environment (PE) and virtual reality (VR) games, demanding spatial temporal accuracy to perceive position motion, precise VMI. Understanding VMI autistic exploring supportive designs VR are crucial for rehabilitation improving accessibility. We assessed static visuospatial ( )...

Visuomotor integration (VMI) impairments are common in children with cerebral palsy (CP) and can impact performance of goal-directed upper-extremity tasks. VMI impairment is clinically assessed using the gold-standard Beery-Buktenica test, whereas research paradigms use computerized assessments incorporating eye hand movement tracking touchscreen displays. Immersive virtual reality (VR) may potentially enable more ecologically valid through inclusion 3D tasks visual distractions. However,...

A remarkable aspect of human behaviour is the ability to respond quickly changes in environment. This behavioral adaptability—a hallmark intelligence—is critical for survival and everyday function. However, question remains open as how sensorimotor adapt physical environments linked cognitive modify internal mental representations. Here, we used altered gravity address this question. Twenty-five participants completed a virtual-reality task that required them their movements non-terrestrial...

Goal-directed throwing is ubiquitous in virtual reality (VR) games, demanding spatial and temporal accuracy to perceive position motion, as well plan, execute movement. Autistic individuals often show superior local visual sensitivity, which may paradoxically delay global processing, leading incongruent visuomotor integration (VMI). Understanding VMI VR exploring supportive designs are vital for enhancing accessibility. We assessed with different levels of cluttering autistic (n = 10)...

Parallel vectors (PV), the loci where two vector fields are parallel, commonly used to represent curvilinear features in 3D for data visualization. Methods extracting PV usually operate on a grid and start with detecting seed points cell face. We propose, best of our knowledge, first provably correct test that determines parity number The only needs sample along face boundary works any choice fields. A discretization is described, validated, compared existing tests also based sampling. can...

Background: Motor impairments contribute to performance variability in children with cerebral palsy (CP) during motor skill learning. Non-immersive virtual environments (VEs) are popular interventions promote learning hemiplegic CP. Greater understanding of as compared typically developing (TD) peers VEs may inform clinical decisions about practice dose and challenge progression. Purpose: (1) To quantify within-child (i.e., across different timepoints) between-child between at the same...

The required actions to solve many everyday motor problems are not immediately apparent. How do children discover these hidden demands? Exploration was assessed in 24- 56-month-olds (n = 47; 26 girls) by tracking how touched a tablet screen open “virtual cabinets” with different locks. Children were strategic explorers. Hypothesis-driven exploration increased age first focusing on the appropriate area (“hypothesis” about where act) and then action act). Even when did hypothesize problem,...

Autistic individuals commonly experience visuomotor integration (VMI) difficulties that impact upper extremity movements such as goal-directed throwing, which exists in everyday activities and movement-based games. often show superior ability towards visual details inefficient global information processing, leading to incongruent VMI. Virtual reality (VR) provides adequate accurate eye hand movement data allows readily individualized design, making it a good option for VMI assessment...
