This study explores the influence of mobile phone secondary tasks on driving from the perspective of visual, auditory, cognitive, and psychomotor (VACP) multiple resource theory, and it is anticipated to benefit the human-centered design of mobile phone use while driving.
The present study investigated 6 typical phone use scenarios while driving and analyzed the effects of phone use distractions on driving performance. Thirty-six participants were recruited to participate in this experiment. We abandoned traditional secondary tasks such as conversations or dialing, in which cognitive resources can become interference. Instead, we adopted an arrow secondary task and an n-back delayed digit recall task.
The results show that all mobile phone use scenarios have a significant influence on driving performance, especially on lateral vehicle control. The visual plus psychomotor resource occupation scenario demonstrated the greatest deterioration of driving performance, and there was a significant deterioration of driving speed and steering wheel angle once the psychomotor resource was occupied.
Phone use distraction leads to visual, cognitive, and/or motor resource functional limitations and thus causes lane violations and traffic accidents.
本研究从视觉、听觉、认知和心理运动（VACP）多资源理论的角度探讨手机次要任务对驾驶的影响，预计将有益于驾驶时手机使用的以人为本设计。
本研究调查了6种典型的驾驶时手机使用场景，并分析了手机使用干扰对驾驶性能的影响。招募了36名参与者参加本实验。我们摒弃了诸如对话或拨号等传统次要任务，在这些任务中认知资源可能会成为干扰因素。相反，我们采用了箭头次要任务和n-back延迟数字回忆任务。
结果表明，所有手机使用场景均对驾驶性能有显著影响，尤其是对车辆横向控制。视觉加心理运动资源占用场景下驾驶性能恶化最为明显，一旦心理运动资源被占用，驾驶速度和方向盘角度就会出现显著恶化。
使用手机造成的干扰会导致视觉、认知和/或运动资源功能受限，从而导致车道违规和交通事故。
