Effects of a Background Arrangement on Collision-Prediction Accuracy for Approaching Objects
- 18 Downloads
This study implemented virtual environment technology to examine how the spacing and height characteristics of a column-type background arrangement affected collision-prediction accuracy for an approaching object set in vast virtual space. Participants were divided into two groups for testing, including the “safety-oriented type” and “accurate judgment type.” Results showed that participants in the safety-oriented type group tended to make collision/non-collision judgments at earlier stages, when columns were higher and more narrow. On the other hand, subjects in the “accurate judgment type” group tended to make accurate collision judgements at later stages (i.e., as column spacing increased).
