Abstract
Predetermined travel locuss are set in a three-dimensional virtual space. Menu panels for displaying menu items are arranged along the travel locuss assuming a display position set as a local origin so that the normal to each LCD panel will face a virtual camera. The transparency of a menu panel is raised in accordance with its distance to the virtual camera. In case a scroll operation is performed, menu panels are moved along the travel locuss connecting display positions P until a selected specific menu panel reaches the display position P0. A display screen on a portable information terminal is drawn as a screen image V shot with the virtual camera and menu panels are three-dimensionally displayed in rolls.
An LCD panel includes an LCD display panel functioning as a display section integral with a transparent touch panel functioning as an input section overlaid on the LCD display panel. By sliding a stylus pen on the LCD panel, that is, by dragging the stylus pen, the menu screen displayed on the LCD panel scrolls at a velocity corresponding to the drag velocity. When the stylus pen is released from the LCD panel 11, that is, performing a tap-out, an application program corresponding to the menu display entity (crosshatched) is activated.
