Abstract:
1. An information processing device comprising: a display device; instruction position detecting circuitry including an operating face provided on a display screen of said display device configured to accept an instruction operation from a user, and to detect and output coordinate information indicating an instruction position corresponding to said instruction operation; detecting circuitry configured to detect, when a tracing operation is performed on said operating face of said instruction position detecting circuitry, an amount-of-operation and an operation direction including a starting position of said tracing operation, based on said coordinate information from said instruction position detecting circuitry; and operating symbol display control circuitry configured to display operating symbols at predetermined positions on the display screen of said display device, and to change a display mode of said operating symbols based on said amount-of-operation and said operation direction of said tracing operation such that said tracing operation of the user is recognizable, wherein the changing of the display mode of said operating symbols corresponds to changing the predetermined positions of said operating symbols in one direction on the display screen of said display device with respect to one another in accordance with said amount-of-operation and said operation direction of said tracing operation, and wherein the changing the predetermined positions of said operating symbols includes
