FOREWORD
This is one of
a series of reports produced as part of a contract to develop precise
and detailed human factors design guidelines for in-vehicle display
icons and other information elements. The contractual effort consists
of three phases: analytical, empirical, and integrative.
This report is
the first product of the analytical phase. It provides a literature
review of research associated with in-vehicle icons and symbols, and
describes current test and evaluation practices for icons. It also summarizes
driver information requirements for in-vehicle messages and the current
use of icons and symbols by manufacturers and after-market vendors.

report can be obtained through the Research and Technology Report Center,

16. Abstract
This report describes the objectives, methods, and findings
associated with Task A: Perform Literature Review. The purpose
of Task A is to conduct a review of relevant symbols and research, including
the use of symbols by manufacturers and after-market vendors for existing
and planned in-vehicle systems. The methodology employed to complete
Task A included: examining articles collected as part of Battelle=s
previous guideline development efforts, conducting extensive database
searches, and accessing the Internet to gather information regarding
the most current use of symbols in existing and future in-vehicle information
systems. More than 200 articles, several books, and more than 100 websites
were found via this methodology.
On the basis of our review and analyses of the literature
for icon and symbol research and current applications, we developed
the following conclusions: (1) the lack of guidelines and standards
for icons has resulted in design by consensus, a lack of scientific
rigor in icon development, and multiple icons for the same messages;
(2) existing literature and standards provide little guidance for the
design of new icons for in-vehicle information system (IVIS) devices;
(3) general design principles for icon design are sufficient to avoid
development of a Abad@
icon, but are not specific enough to support development of the Abest@
icon; (4) development of new icons and symbols for in-vehicle devices
will require iterative testing and evaluation; existing test and evaluation
methods provide sufficient scientific rigor for future evaluations of
icons and symbols; and (5) despite industry concerns over the utility
and relevance of human factors design guidelines, rigorous and proven
methods for design guideline development exist and will be used in Tasks
C and F of this project.
