  • Publication number: 20110160957
    Abstract: An indication unit indicates arranged selective areas on a display surface for accepting input. A move unit moves an instructed position on the display surface according to an operation quantity of an operation unit. A selected-state determination unit determines a selected-state area from the selective areas according to the instructed position. A width determination unit determines a width of the selected-state area in each of an x-axis direction and a y-axis direction of the display surface. A moving speed set unit sets a moving speed of the instructed position variably at least when the instructed position passes through the selected-state area such that: a velocity component in the x-axis direction becomes larger as the determined width in the x-axis direction becomes larger, and a velocity component in the y-axis direction becomes larger as the determined width in the y-axis direction becomes larger.
