How People With Vision Impairment Use Their Gaze to Hit a Ball.
Purpose: Understanding the impact of vision impairment on dynamic tasks requiring visual processing is crucial for developing effective adaptive strategies that support individuals with vision impairment in optimizing their performance in natural tasks. This study aimed to establish the gaze patterns used by individuals with vision impairment when hitting a moving target.
Methods: Nineteen tennis players with vision impairment were recruited and their eye and head movements were tracked while they returned tennis serves.
Results: Participants used a variety of different strategies to track the ball visually, dictated largely by the nature of their impairment rather than its severity. Cluster analysis showed distinct strategies based on the type of vision impairment: those with peripheral vision loss foveated the ball closely and avoided predictive eye movements; those with poor oculomotor control initially tracked the ball but lagged as it approached; and those with central vision loss used a variety of strategies that did not align with the use of a single preferred retinal locus: some tracked the ball using a single preferred location in their peripheral vision, some switched the area of retina used to track the ball, and another did not move their gaze at all.
Conclusions: Tennis players with vision impairment adopt a variety of impairment-specific adaptations to their gaze-tracking strategies, enabling them to successfully hit an approaching tennis ball despite severe vision impairments.
Translational relevance: This study provides insight into the impairment-specific gaze strategies that well-adapted individuals with vision impairment adopt when hitting a moving target.
期刊介绍:
Translational Vision Science & Technology (TVST), an official journal of the Association for Research in Vision and Ophthalmology (ARVO), an international organization whose purpose is to advance research worldwide into understanding the visual system and preventing, treating and curing its disorders, is an online, open access, peer-reviewed journal emphasizing multidisciplinary research that bridges the gap between basic research and clinical care. A highly qualified and diverse group of Associate Editors and Editorial Board Members is led by Editor-in-Chief Marco Zarbin, MD, PhD, FARVO.
The journal covers a broad spectrum of work, including but not limited to:
Applications of stem cell technology for regenerative medicine,
Development of new animal models of human diseases,
Tissue bioengineering,
Chemical engineering to improve virus-based gene delivery,
Nanotechnology for drug delivery,
Design and synthesis of artificial extracellular matrices,
Development of a true microsurgical operating environment,
Refining data analysis algorithms to improve in vivo imaging technology,
Results of Phase 1 clinical trials,
Reverse translational ("bedside to bench") research.
TVST seeks manuscripts from scientists and clinicians with diverse backgrounds ranging from basic chemistry to ophthalmic surgery that will advance or change the way we understand and/or treat vision-threatening diseases. TVST encourages the use of color, multimedia, hyperlinks, program code and other digital enhancements.
