Development of a Dynamic Visual Acuity Training Software Based on Baseball Situations to Improve Users' Dynamic Visual Ability

Abstract: Dynamic visual acuity (DVA) is crucial for successful baseball batting, as it enables players to quickly assess the ball’s trajectory and adjust their swing timing in a short period of time. This study involved interviews with 19 baseball coaches and players from four collegiate teams, as well as questionnaire distribution and a literature review, revealed that visual training is underutilized in baseball from youth to professional levels. Existing training products often lack customization to individual abilities and struggle to translate training effect to on-field performance. Recent advances in virtual reality (VR) have been applied to baseball training, but issues such as motion sickness remain. To address these gaps, this study developed a dynamic vision training software with three modes: (1) Simulation Mode, (2) Track Blocking Mode, and (3) Texture Contrast Mode. The software adjusts difficulty based on an 80% accuracy threshold and focuses on training players to recognize fine details, such as the seams on a fast-moving ball. To evaluate the software's effectiveness, 18 non-athletic participants were recruited and divided among the three training modes. Each group underwent a pre-test, completed eight training sessions, and finished with a post-test. Results showed an overall improvement in personal ability rating, with statistical significance in the Simulation and Track Blocking Modes, but not in the Texture Contrast Mode, possibly due to eye fatigue in one participant. The study demonstrates that this software allows teams to flexibly schedule training and enhances real-world performance more effectively than other visual training tools.
