Summary
This study addresses the gap in research regarding how older adults perceive in-vehicle information systems (IVIS). While IVIS are designed to enhance the driving experience for all ages, few studies have explored the specific challenges and perceptions of older drivers, who often report frustration and negative feelings when interacting with advanced technology. With an aging population, understanding these subjective experiences is critical for designing safer and more accessible vehicles. The research specifically investigates the observations, concerns, and recommendations voiced by both older and younger drivers regarding IVIS, and whether these responses differ in emotional valence. The methodology involved an on-road driving study with 128 participants, comprising younger drivers (mean age 24.8) and older drivers (mean age 65.8). Participants were asked open-ended questions about their experiences with IVIS. The researchers employed a multi-phase Inductive Thematic Analysis (ITA) to code participant comments, using a hybrid of categorical and thematic approaches to capture the diversity of implicit meanings. Comments were categorized into themes such as Safety/Risk, Familiarity and Learning, General Usability, Real World application, Physical Design, Comparative Statements, and Miscellaneous. Additionally, a chi-square analysis was used to interpret the valence (positive, negative, or neutral) of the comments across age groups. The results revealed that both age groups predominantly expressed negative valence across most thematic categories. Older drivers made significantly more comments related to Safety and Risk than younger drivers. In categories such as Familiarity and Learning, General Usability, and Real World application, both groups provided overwhelmingly negative feedback. Notably, younger drivers provided no positive comments regarding Real World applications or Miscellaneous issues. Despite the negative sentiment, a key finding emerged regarding willingness to learn: older drivers expressed a broader willingness to take the time necessary to become familiar with new systems, whereas younger drivers often expressed futility toward poorly designed interfaces. Older drivers were found to be more forgiving of inconvenient designs, despite finding them initially more difficult to learn. The significance of these findings lies in challenging the misconception that older drivers are less engaged with or resistant to new technologies. The study suggests that older adults are more willing to adapt and learn, highlighting the importance of Universal Design principles that ensure accessibility and ease of use for all users. The authors conclude that while subjective accounts may show similarities between age groups, physiological differences likely mean older drivers experience these technologies differently. Future research is needed to bridge the disparity between performance and perception, informing the development of inclusive IVIS designs and refining theoretical frameworks like the Unified Theory of Acceptance and Use of Technology.
Key finding
Both older and younger drivers expressed predominantly negative impressions of IVIS, with most comments centered on General Usability. Older drivers made more Safety/Risk comments and were notably more open than younger drivers to additional training, suggesting they are more forgiving of inconvenient interfaces and willing to invest time learning, while younger drivers expressed futility with systems they viewed as poorly designed. The authors argue these findings support Universal Design principles for IVIS.
