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 a summary of the analytical, empirical, and integrative phases of the In-Vehicle Display Icons and Other Information Elements project. It is an overview of the process used to meet the primary goal of the project: to provide designers of in-vehicle technologies with a set of design guidelines for in-vehicle display icons and other information elements.

16. Abstract
Because of the speed with which IVIS devices are entering the automotive marketplace, many research issues associated with the design of in-vehicle visual symbols and other information elements have not been adequately addressed. The overall goal of the In-Vehicle Display Icons and Other Information Elements project has been to provide the designers of these in-vehicle technologies with a set of design guidelines for in-vehicle display icons and other information elements. Specific objectives of this project were to:
- Design and perform experimentation to select appropriate symbols for in-vehicle use, then analyze the resulting data to write final guidelines for in-vehicle sysmbols usage encompassing both current and future symbols.
- Write preliminary, as well as empirically based, final guidelines.
The key product of this project is a set of clear, concise, and user-centered human factors design guidelines for in-vehicle icon design. The guidelines address issues such as the legibility, recognition, interpretation, and evaluation of graphical and text-based icons and symbols. These guidelines provide IVIS developers with key information regarding the use and integration of existing and new visual symbols. In addition, the Icon IDEA software tool developed in this project has provided a real-time icon development and evaluation tool that, to-date, is receiving consistently positive reviews from the project's working group members. This tool is entirely functional and ready to use, and should prove to be an invaluable aid and resource for icon design.
