1. A scrolling method, comprising:
receiving input values including pointing locations from a pointing device; storing the received input values in a storage unit; selecting input values, which are stored during a preset time period, from the storage unit; giving weight to each pointing location of the selected input values in proportion to a difference in time between successively generated time points of the selected input values from a beginning of the preset time period to a current time point, wherein the generated time points are time points when the input values are generated, and wherein the preset time period is a period of time that ends at the current time point; calculating a result value for scrolling of content being displayed by averaging pointing locations which have been given the weight; and controlling the scroll using the calculated result value.
