        Today's driver information system often features a rotary control type as a main controller for menu navigation. Population stereotype should be clearly understood in designing those systems to minimize the misunderstanding by the operator. This paper investigates stereotypes for rotary controlled menu interfaces and influences of contributing principles. A human factors experiment was conducted using various configurations of control-display layouts, cursor shapes/positions, and movement directions. The results showed that the control should be on the left of the display, with a rightward icon on the right side of the cursor, in order to match the stereotype. Regression analysis indicated that Warrick's principle was the most influential principle, followed by Icon shape, Icon position, Clockwise away, and Clockwise up principles. This study provides valuable information to designers of menu-based systems such as driver information systems and main control rooms that uses rotary controls.

        The propagation of water waves over irregular bottom bathymetry and around islands involves many process-shoaling, refraction, energy dissipation and diffraction. Numerical model in this study is developed with the mild slope equation to investigate wave transformation in water of varying depth and combined waves and a current. The method used is splitting method and minimax approximation. The numerical method used in this study is Crank-Nicolson scheme in the FDM. This model is applied to Vincent shoal and compared with laboratory experimental data. The results agreed well with laboratory data. Current effect is considered in this study. This model can be used for the estimation of rip current in the slowly varying topography.
