“…Accurate locational and regional information such as road names and numbers need to be stored. Third, real-time synchronisation and system integration are required to send and retrieve the correct data at the right time (Ariyoshi et al 1988;Gilliéron and Merminod 2003;Narzt et al 2004;Robertson and Cipolla 2004). Following the introduction of these technologies in the first commercial car navigation system by Steven Lobbezoo in 1985, they have become essential elements of car navigation systems (Autos.ca 2011).…”

This study proposes an integrated research model for investigating driver adoption of car navigation systems. We consider the potential causal connections between core cognitive and psychological factors and driver intention to use these systems. We extracted possible factors that may significantly affect the perceived usability of car navigation systems from in-depth interviews with two groups of individuals: an expert group and a driver group. Data collected from N = 1045 drivers via an online survey were analysed by structural equation modelling. The results showed that the service & display quality components of the systems were the most significant determinants of driver attitude and intention to use car navigation systems. Two other factors, namely attitude and perceived usefulness, also had impacts on driver intention. Moreover, both satisfaction and service & display quality were affected by perceived system reliability, while usefulness was affected by both perceived locational accuracy and satisfaction. Satisfaction also significantly affected perceived ease of use. In addition, we introduced new external variables to the technology acceptance model (TAM) and validated the causal connections proposed by the original TAM. The present study provides valuable insights into the core factors that significantly affect driver perspectives of and intention to use car navigation systems.

“…Narzt et al [14] envision a wholewindshield HUD with navigational information overlaid onto the road surface as transparent colored paths. Charissis et al [5] prototyped a system that superimposes virtual representations of objects onto the driving scene, providing early warnings of impending sharp turns or traffic slowdowns that might otherwise be missed due to weather conditions such as fog.…”

It has been established that head-down displays (HDDs), such as those commonly placed in the dashboard of commercial automobiles, negatively affect drivers' visual attention [1]. This problem can be exacerbated when screens are "busy" with graphics or rich information. In this paper, which is an extension of a user-preference study [23], we present the results of a driving simulator experiment where we examined two potential alternatives to HDDs for presenting textual lists. Subjects conducted a series of street name finding tasks using each of three system variants: one with a head-down display (HDD), one with a head-up display (HUD), and one with only an auditory display. We found that the auditory display had the least impact on driving performance and mental load, but at the expense of task completion efficiency. The HUD variant had a low impact on mental load and scored highest in user satisfaction, and therefore appears to be the most viable target for future study.

“…Typically, line features aligned with the course of the route or arrows at decision points are integrated in the visualization to guide the user. These elements can be integrated, for example, within live video imagery as an overlay showing route indicators in a perspectively correct way (Narzt et al 2004). In (Coors et al 2005), multi-modal representations of routes are analyzed, including verbal instructions, 2D and 3D route hints.…”

Research in cognitive sciences suggests that orientation and navigation along routes can be improved if the graphical representation is aligned with the user's mental concepts of a route. In this paper, we analyze an existing 2D schematization approach called wayfinding choremes and present an implementation for virtual 3D urban models, transferring the approach to 3D. To create the virtual environment, we transform the junctions of a route defined for a given road network to comply with the eight sector model, that is, outgoing legs of a junction are slightly rotated to align with prototypical directions in 45° increments. Then, the adapted road network is decomposed into polygonal block cells, the individual polygons are extruded to blocks and their façades are textured. For the evaluation of our 3D wayfinding choreme implementation, we present an EARLY DRAFT experiment framework that allows to train and test subjects by route learning tasks. The experiment framework can be parameterized flexibly, exposing parameters to the conductor. We finally give a sketch of a user study by identifying hypotheses, indicators, and, hence, experiments to be done.
