The Relationship between the Variation in Line Drawing Based on Point Cloud and the Reaction Delay Root Mean Square / the Reaction Time in a Simulated Driving Task

Abstract

In this study, we investigate the relationship between the variability (consistency) of line drawing based on point clouds and the reaction delay RMS (root mean square) / the variability of reaction time during a simulated driving task. In order to examine this relationship, 23 participants performed a line drawing task three times and a simulated driving task, and the correlation was examined. The results suggests that inconsistency of line drawing is positively correlated with the reaction delay RMS / the variability of reaction time where the correlation coefficient was about 0.7. The results of multiple regression analysis show that the consistency of the line drawing can predict the reaction delay RMS / the variability of reaction time (coefficient of determination: 0.50, 0.48). From these results, we conclude that people who tend to change the criteria for drawing lines in a certain point clouds are also likely to show variability in a simulated driving task.
