车载导航系统 (IVNS) 有可能使老年驾驶员受益，减少与寻路相关的压力并提供旅途支持，尤其是在不熟悉的地点。然而，现有的 IVNS 对可用性提出了挑战，导致缺乏采用和过度依赖出行前计划。本文提出的研究旨在确定使 IVNS 用户友好且适合老年驾驶员的功能。研究模拟驾驶环境中的导航性能，重点关注具有路线引导信息的地标的使用，以及最合适的信息提供方法（仅音频、仅视频或音频和视频的组合）。它还评估基于地标的导航信息可能出现的潜在性别差异。解决方案包括使用适当的路边地标，以及通过音频和基于图标的视觉格式相结合来传递信息。这些功能可降低工作量并减少导航错误。与其他方式相比，音频/视觉方式减少了地标分散注意力的风险，从而减少了视线扫视次数，缩短了扫视路边的时间。根据老年驾驶员的需求设计和提供 IVNS 可以为更长时间地保持个人流动性做出巨大贡献。 (C) 2016 年作者。由爱思唯尔有限公司出版
In-vehicle navigation systems (IVNS) have the potential to benefit older drivers, reducing stress associated with way-finding and providing on-trip support, especially in unfamiliar locations. However, existing IVNS present challenges to usability, resulting in lack of uptake and over-reliance on pre-trip planning.This paper presents research aimed at identifying features that make IVNS user-friendly and appropriate for older drivers. Studying navigational performance within a simulated driving environment, it focuses on the use of landmarks with route guidance information, and the most appropriate method of information provision (audio only, visual only or a combination of audio and visual). It also assesses potential gender differences that might arise with landmark-based navigational information.Solutions include use of appropriate roadside landmarks, and information delivered through a combination of audio and icon-based visual format. These features result in lower workload and fewer navigational errors. The audio/visual modality reduces the hazard of distraction by landmarks resulting in fewer visual glances and lower glance duration to the roadside compared to other modalities.Design and provision of IVNS tailored to older drivers' needs can make a considerable contribution to maintaining individual mobility for longer.
