Abstract:
1. An input apparatus for controlling a movement of a pointer on a screen, the input apparatus comprising: a casing; a movement signal output means for detecting a three-dimensional movement of the casing and outputting a signal of a velocity-related value that is related to a velocity of the casing, wherein the movement signal output means includes: a comparison means for comparing the first velocity value and the second velocity value that have been calculated; a gain means for obtaining a pointer velocity value as a velocity value for moving the pointer on the screen by multiplying the output velocity-related value by a gain; a control means for variably controlling the gain in a first range in which the output velocity-related value ranges from a first threshold value to a second threshold value larger than the first threshold value, and controlling the gain to be constant in a second range in which the output velocity-related value exceeds the second threshold value, wherein the control means controls the gain with respect to a larger one of the first velocity value and the second velocity value as a result of the comparison; and a transmission means for transmitting information on the pointer velocity value obtained by the gain means.
