“…This algorithm has been found to be the most similar to manual detection from human experts ( Andersson et al, 2017 ). In the present study, fixations were marked using a 1 ° spatial dispersion threshold ( Blignaut, 2009 ; Arthur et al, 2021 ) and a minimum duration of 60 ms ( Komogortsev et al, 2010 ). To test the reliability of the results presented in our study, we used the eye movement metrics to compare the eye movement results obtained from the IDT algorithm with the three dispersion thresholds (1, 1.2, and 1.4 ° ).…”

IntroductionEye-tracking technology provides a reliable and cost-effective approach to characterize mental representation according to specific patterns. Mental rotation tasks, referring to the mental representation and transformation of visual information, have been widely used to examine visuospatial ability. In these tasks, participants visually perceive three-dimensional (3D) objects and mentally rotate them until they identify whether the paired objects are identical or mirrored. In most studies, 3D objects are presented using two-dimensional (2D) images on a computer screen. Currently, visual neuroscience tends to investigate visual behavior responding to naturalistic stimuli rather than image stimuli. Virtual reality (VR) is an emerging technology used to provide naturalistic stimuli, allowing the investigation of behavioral features in an immersive environment similar to the real world. However, mental rotation tasks using 3D objects in immersive VR have been rarely reported.MethodsHere, we designed a VR mental rotation task using 3D stimuli presented in a head-mounted display (HMD). An eye tracker incorporated into the HMD was used to examine eye movement characteristics during the task synchronically. The stimuli were virtual paired objects oriented at specific angular disparities (0, 60, 120, and 180°). We recruited thirty-three participants who were required to determine whether the paired 3D objects were identical or mirrored.ResultsBehavioral results demonstrated that the response times when comparing mirrored objects were longer than identical objects. Eye-movement results showed that the percent fixation time, the number of within-object fixations, and the number of saccades for the mirrored objects were significantly lower than that for the identical objects, providing further explanations for the behavioral results.DiscussionIn the present work, we examined behavioral and eye movement characteristics during a VR mental rotation task using 3D stimuli. Significant differences were observed in response times and eye movement metrics between identical and mirrored objects. The eye movement data provided further explanation for the behavioral results in the VR mental rotation task.

“…Rafique and colleagues recently investigated the effects of accommodation anomalies which contribute to motor skills impairment [ 53 ]. Some atypicalities in ocular motility have been identified in patients with DCD [ 54 ], in particular with regard to sustained engagement on fixation (deficient in subjects with DCD) and differences in gaze behavior compared to control groups [ 55 , 56 ]. Gaze training was investigated in order to verify whether it caused, retrospectively, benefits in the organization of the movement [ 57 ].…”

This narrative review describes, in detail, the relationships between Developmental Coordination Disorder (DCD) and most prevalent associated comorbidities in their complexity, heterogeneity and multifactoriality. The research has been conducted on the main scientific databases, excluding single case papers. Blurred borders between the different nosographic entities have been described and advances in this field have been highlighted. In this multifaceted framework a specific profiling for co-occurring DCD, ADHD and ASD signs and symptoms is proposed, confirming the need for a multidisciplinary approach to define new diagnostic paradigms in early childhood.

“…There are a few works [34,35] that consider body movement and visual movement jointly to make a comprehensive behavioral analysis of DCD. Parr et al [34] used a 26-camera motion capture system (Vicon MX) and a Pupil labs eye-tracker to analysis the kinematic variables and gaze variables and investigate the visuomotor control strategies of children with and without DCD.…”

“…Parr et al [34] used a 26-camera motion capture system (Vicon MX) and a Pupil labs eye-tracker to analysis the kinematic variables and gaze variables and investigate the visuomotor control strategies of children with and without DCD. Similarly, in [35], Arthur et al applied the same equipment to examine the hand and eye movements of children with DCD during object interaction. However, the motion capture system used in [34,35] requires many reflective markers to be attached on the participants, which limits the application range of this type of motion capture system, especially in the motion ability assessment of children, because the pasted markers may distract children and bring physical discomfort.…”

Developmental coordination disorder (DCD) is a motor learning disability with a prevalence of 5%-6% in school-aged children, which may seriously affect the physical and mental health of affected children. Behavior analysis of children helps explore the mechanism of DCD and develop better diagnosis protocols. In this study, we investigate the behavioral pattern of children with DCD in the gross movement using a visual-motor tracking system. First, visual components of interest are detected and extracted using a series of intelligent algorithms. Then, the kinematic features are defined and calculated to describe the children behavior, including eye movement, body movement, and interacting object trajectory. Finally, statistical analysis is conducted both between groups with different motor coordination abilities and between groups with different task outcomes. The experimental results show that groups of children with different coordination abilities differ significantly both in the duration of eye gaze focusing on the target and in the degree of concentration during aiming, which can serve as behavioral markers to distinguish children with DCD. This finding also provides precise guidance for the interventions for children with DCD. In addition to increasing the amount of time spent on concentrating, we should focus on improving children's attention levels.
