无人物流车的车外屏人机界面设计研究

随着智能汽车和物流行业快速发展，产业结合促进了无人物流车的出现。为了提 高无人物流车的安全、效率和用户体验，对无人物流车的车外屏人机界面设计进行研究。首先 提出了基于无人物流车的人-车-环境关系理论，并且结合物流车的运行场景流程对车外屏人机 界面的设计需求进行了研究。在此基础上，对无人物流车的车外屏人机界面的信息架构、多通 道交互模式及界面设计进行了探讨和设计实践，并且对物品回收功能的初步原型设计进行了可 用性测试评估。测试结果显示初步的无人物流车车外屏交互原型逻辑流畅，可用性较高。调查 结果显示用户希望无人车定位准确，并且可以利用积分制来兑换物质奖励。研究表明车外屏人 机界面设计可以提高无人物流车的安全、效率和用户体验。对无人物流车的车外屏设计进行修 改和完善，并且经过测试迭代后，将会不断提升车外屏设计。

Research on human-machine interface design of exterior screen of driverless delivery car

With the rapid development of intelligent vehicles and logistics, and the combination of these two industries has promoted the emergence of driverless delivery cars. In order to improve the safety, efficiency and user experience of the driverless delivery car, the design of the human-machine interface (HMI) of the car’s exterior screen was studied. We first put forward the theory of human-vehicle-environment relationship based on driverless delivery cars, and studied the design requirements of vehicle exterior interface in view of the running scenario flow of delivery cars. On this basis, the information architecture, multi-channel interaction mode and interface design of the exterior interface of the driverless delivery car were discussed and practiced, and the usability test was conducted regarding the preliminary prototype design of recycling function. The test results show that the preliminary interactive prototype of the driverless delivery car’s exterior screen runs logically smoothly and has high usability. The survey results show the users’ hope for the driverless delivery car to be accurately located and the use of the points system for exchanging material rewards. This research indicates that HMI design can improve the safety, efficiency and user experience of the driverless delivery car. Through modifying and perfecting the design of the exterior screen with test and iteration, the design of the exterior screen will be continuously improved.
