摘要: In this study, the authors investigated how restriction of vertical viewing angle influences obstacle-crossing behavior. Twelve participants stepped over obstacles different dimensions while wearing visual-field-restricting goggles. Using full-body motion capture, several kinematic measures were extracted and analyzed. Results indicate that both a 40° 90° yielded increased step length toe clearance as compared to an unrestricted view (i.e., 135°), whereas speed remained unaltered. A further decrease (to 25°) caused slow down in addition increase clearance. These results are discussed terms change priorities, from conservation energy time safety.
