Using a ‘value-added’ approach for contextual design of geographic information

Abstract

Additional Information:• AbstractThe aim of this article is to demonstrate how a 'value-added' approach can be used for user-centred design of geographic information. An information science perspective was used, with value being the difference in outcomes arising from alternative information sets. Sixteen drivers navigated a complex, unfamiliar urban route, using visual and verbal instructions representing the distance-to-turn and junction layout information presented by typical satellite navigation systems. Data measuring driving errors, navigation errors and driver confidence were collected throughout the trial. The results show how driver performance varied considerably according to the geographic context at specific locations, and that there are specific opportunities to add value with enhanced geographical information. The conclusions are that a value-added approach facilitates a more explicit focus on 'desired' (and feasible) levels of end user performance with different information sets, and is a potentially effective approach to user-centred design of geographic information.

Digital, analogue, or redundant speedometers for truck driving: Impact on visual distraction, efficiency and usability

“…Findings concluded that performances were good for ambient-visual, auditory, and tactile speedometer displays, and that redundancy with an auditory display, such as beat pattern, was beneficial (Yang & Ferris, 2016). Another solution might be to investigate dynamic interfaces, in order to provide additional relevant information (May, 2013;Davidsson & Alm, 2014). This perspective would be particularly suitable for displaying additional speed information, such as displaying the speed limit information only when the speed limit is broken.…”

Evaluating a concept design of a crowd-sourced ‘mashup’ providing ease-of-access information for people with limited mobility

“…Perspectives based on outcomes focus on the changes in behaviour that result from presenting alternative information sets to the end user. An example related to the added value of geographical information is provided by May (2013). Finally, a perceived value approach (Zeithaml, 1988;Sweeney and Soutar, 2001) takes a consumer perspective, and analyses the overall assessment of a product or service based on what is 'received', versus what is 'given'.…”

User-centred design of neogeography: the impact of volunteered geographic information on users' perceptions of online map ‘mashups’

“…It is possible that those who volunteered to participate were more socially motivated and confident using online maps than the general population, although these are also likely to be the particular subset of the user group who would make most use of online mashups. A further limitation of this form of study was that the user outcome measures were based on participant judgements, as opposed to actual differences in task-based outcomes arising from use of alternative information sets within a geographic context (May 2013).…”
