Method And Apparatus For Area-Efficient Graphical User Interface

A user operates a GUI with a thumb and an index finger while holding an information processing device with left and right hands. The GUI screen image displays a directional keys input area at the lower left on the screen image, a button input area at the lower right on the screen image, an L1/L2 button input area at the upper left on the screen image, and an R1/R2 button input area at the upper right on the screen image. The L1/L2 and the R1/R2 button input areas are in the form of circle sectors, whereby the center angles of the circle sectors are at right angles of the two upper corners of the screen, and by internally dividing the center angles further so as to divide the sectors into two sectors respectively, the L1 and L2 buttons, and the R1 and R2 buttons are distinguished.
