Enhancing Human Augmentation: Analysis of Behavior Change in Highly Efficient Three-Hand Body After Motor Skill Training

This paper investigates the behavior changes observed in individuals utilizing a highly efficient three-hand body in VR with 3rd Hand equipped on left shoulder after motor skill training. The study focuses on spatial awareness and cooperative action and explores the implications for future research and augmentation body design. Participants underwent a six-round training program involving tasks to enhance their proficiency with the three-hand body. Pre- and post-training evaluations were conducted in two conditions: spatial awareness (C1) and cooperative action (C2). Results revealed distinct hand preferences and usage ranges. In C1, participants showed biases towards their respective hand positions, with improved decision-making between the left and third hands post-training. In C2, the third hand usage shifted towards the right side, indicating a preference for a partnership with the right hand and improved cooperative action between the hands. These findings provide insights into behavior changes and performance enhancements. Further research is needed to explore the impact of training on the natural body and potential sense of loss experienced by individuals. This study contributes to our understanding of human body perception and the optimization of motor skill training systems for augmentation bodies.
