The purpose of this study is to suggest an appropriate menu structure of IVIS, to be implemented on the instrument cluster panel, using Taguchi's parameter design. The research consists of three steps: (1) select a set of functions that are appropriate to control through the instrument cluster among existing functions of current IVISs by quantitative evaluation of ergonomic principles; (2) extract menu structure alternatives by investigating priorities to those functions selected; and (3) evaluate menu structure alternatives through an experiment and suggest the most appropriate one by applying Taguchi's parameter design. Taguchi method plays a significant role in this research in terms of planning an experiment and evaluating alternatives. The experiment was structured as Taguchi method suggested, i.e., the use of inner and outer arrays. SN ratios were calculated and evaluated for all alternatives in order to find the most proper one. The most appropriate menu structure for the instrument cluster IVIS was finally suggested among the alternatives and the usefulness of Taguchi's parameter design was discussed. It is expected that the results of this research could provide a guideline to the instrument cluster IVIS and Taguchi's parameter design could be suggested as an effective method for evaluating menu design alternatives.
