An information apparatus includes a display unit which displays an icon, a pointer, and the like, and a pointing device. When the pointer executes predetermined movement and stop in an icon-selection effective region formed in a periphery of the icon, the information apparatus determines that the pointer has selected the above-described icon. It is possible to apply a menu item in place of the icon. It is possible to set plural conditions for determining that the icon has been selected. It is possible for an operator to easily select the icon and the like on a small display unit by using the pointing device.
