Exploring the Relationship Between the Interactive Range of Objects and the Performance of Freehand Grasping Interaction in Glasses-Free 3D Scenes

Target selection is one of the most essential and common tasks in 3D interaction. Grasping interaction is an innate ability of human beings. As the most basic form of target selection interaction, it is widely used in target selection tasks. Previous work has explored the impact of various feedback factors on the interaction efficiency of grasping target selection. However, research has yet to focus on the impact of the interactive range of objects on target selection efficiency. This study takes the interactive range of objects as the research goal, builds an experimental platform based on a glasses-free 3D display, and evaluates the impact of the interactive range of objects on grasping performance and task load under different interactive object layouts. The results show that the interactive range of objects significantly impacts the performance and accuracy of grasping interaction. Reducing the interactive range can improve accuracy and increase the time spent on the task. Increasing the interactive range can shorten the time spent on the task. However, it will also reduce the accuracy. We also observe that the interactive range does not significantly impact the task load. This study initially reveals the relationship between the interactive range of objects and target selection task performance and experience. It provides suggestions for the design of three-dimensional interactive applications.
