In-Car Road Information: Comparisons of Auditory and Visual Presentations

Abstract

Two studies investigate the effects of presentation modalities (visual/auditory/repeated auditory) and complexity levels of different in- car road information on subjective preferences and on perceptual and cognitive performances of drivers. In real driving situations, each driver was alerted by a ringing signal prior to the presentation of a road information message or a map display associated with a road guidance message; the experimenter asked each driver 30 s. later to recall the message or the itinerary. Results suggest that in real driving situations, short auditory road information messages or associated with map displays optimize perceptual and cognitive performances and driving safety; written messages are of greater interest if screened when the vehicle is at rest.

Iterative design of MOVE: A situationally appropriate vehicle navigation system

“…Displays on current in-vehicle navigation systems are often modeled after paper maps, and have similar visual complexity. Therefore, some research has suggested that, due to the visual complexity of map data, it is important to limit the amount of information presented to the driver when they are driving (Streeter et al, 1985;Labiale, 1990;Parks et al, 1991), and even suggested that map information only be presented when the vehicle is stationary (Michon, 1993;Ross et al, 1995). Because relatively small displays are often used, such systems almost always allow the user to zoom into areas of interest in the current driving context to display an affordable amount of information to a driver.…”

Evaluation of the Cartographic Communication Performance of a Route Guidance and Navigation System

“…These applications could be too visually and cognitively demanding, requiring immediate attention, which could override a focus on driving (Green 2000b). According to Labiale (1990) and Liu (2000), short auditory displays combined with visual displays (multimodality) might optimize perceptual and cognitive performance. In addition, Labiale (2001) found that each guidance information representation factor (the number of exit roads, the presence or absence of a landmark and the kind of intersections) has an impact on visual demand.…”

Drivers' preferences and emotional responses to satellite navigation voices

“…Verbal delivery of route-guidance instructions reduces workload and visual distraction compared to visual-only delivery (Lansdown, 1996). In comparative studies, subjects made fewer glances away from the road when messages were delivered verbally (Labiale, 1990;Lansdown, 1996), responded more quickly to verbal instructions (Verwey, 1989(Verwey, , 1993 and made less navigational errors (Lansdown, 1996;Streeter et al, 1985).…”
