Information processing apparatus, information processing method and information processing program for performing a tracing operation

摘要

To present the operating state of a tracing operation in the event of performing a tracing operation to scroll objects of display. Upon a tracing operation being performed as to the operating face of an input detection device (i) provided on the display face of a display device (5), coordinate information indicating he instructed position corresponding to the tracing operations is output from the input detection device (I). A user interface control unit (2) detects the operation direction and amount-of-operation with the starting position of the tracing operation as a reference, based on the coordinate information from the input detection device (i), and effects control so as to change the display mode of operating symbols displayed on the display screen of the display device (5).

主权项

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
changing respective positions of each of the operating symbols in the one direction on the display screen based on said amount-of-operation and said operation direction of said tracing operation, andchanging interval distances between said operating symbols in the one direction based on said amount-of-operation and said operation direction of said tracing operation.
