Patent ID: 7522151

Claim:
A method for translating input motion information into movement of a display object comprising: establishing a direction-specific leading-in area based on an initial motion direction in a first direction obtained from input motion information, determining a direction of motion after the initial motion direction by evaluating whether subsequent coordinates of an input motion fall within the direction-specific leading-in area established by the initial motion direction, switching the direction-specific leading-in area of the first direction for a direction-specific leading-in area of a second direction in response to changes in the amount of motion input in the first direction and the amount of motion input in the second direction, and altering a shape of the established direction-specific leading-in area in response to continuous motion input in the first direction; wherein the motion component in the first direction being in the x direction of a coordinate system and the motion component in the second direction being in the y direction of a coordinate system; and the direction-specific leading-in area for the x direction comprising an area along the x-axis bounded by lines y=ax and y=−ax where ‘ a’ is a number greater than 1 and the direction-specific leading-in area for the y direction comprising an area along the y-axis bounded by lines y=x/a and y=x/(−a) where ‘a’ is number greater than 1, and further wherein said altering a shape comprises increasing or decreasing the value of ‘a’.
