Program execution system, program execution device, recording medium, program used in the program execution device, method for switching viewpoint on display device and a method for switching aim on display device of the system

A program execution device to which can be connected at least an operation device that outputs operation instructions in accordance with user's operation and a display device for displaying images, the program execution device comprising:

• a discrimination means that distinguishes a switching direction of a viewpoint in said display device based on a combination of output information output from said operation device in accordance with operation instructions from the user to first and second leftward instruction buttons and first and second rightward instruction buttons provided on said operation device;
• and
• a display switching means that switches said viewpoint to said switching direction distinguished by said discrimination means.

A program execution device to which can be connected at least an operation device that outputs operation instructions in accordance with user's operation and a display device for displaying images, the program execution device comprising:

• a discrimination means that distinguishes a switching direction of a virtual aim in said display device based on a combination of output information output from said operation device in accordance with operation instructions from the user to first and second leftward instruction buttons and first and second rightward instruction buttons provided on said operation device;
• and
• a display switching means that switches said virtual aim to said switching direction distinguished by said discrimination means.

A recording medium on which are recorded a program and data used in a program execution system including a program execution device that executes programs, at least one operation device that inputs operation instructions in accordance with user's operation to said program execution device, and a display device that displays images output from said program execution device, the program comprising:

• a discrimination step that distinguishes a switching direction of a viewpoint in said display device based on a combination of output information output from said operation device in accordance with operation instructions from the user to first and second leftward instruction buttons and first and second rightward instruction buttons provided on said operation device;
• and
• a display switching step that switches said viewpoint to said switching direction distinguished by said discrimination step.
