Information processing apparatus and storage medium storing information processing program

An information processing apparatus which can communicate with an input device performing a pointing action by using an image capturing device for capturing an image of a target object, and calculate a pointing position on a screen of a display device based on the image captured by the image capturing device, wherein

• the input device comprises a motion-attitude detector configured to detect a motion or an attitude of the input device,
• the information processing apparatus comprising a processor configured to:
• calculate a tilt value indicating a tilt of the input device using a result of detection by the motion-attitude detector;
• determine whether or not the pointing position can be calculated based on the image captured by the image capturing device;
• compare the calculated tilt value with a reference value when the pointing position cannot be calculated;
• and
• output information about the tilt of the input device, depending on a result of comparison.

A method of operating an information processing apparatus which can communicate with an input device performing a pointing action by using an image capturing device for capturing an image of a target object, and calculating a pointing position on a screen of a display device based on the image captured by the image capturing device, wherein the input device comprises a motion-attitude detector configured to detect a motion or an attitude of the input device, the method comprising:

• calculating a tilt value indicating a tilt of the input device using a result of detection by the motion-attitude detector;
• determining whether or not the pointing position can be calculated based on the image captured by the image capturing device;
• comparing the calculated tilt value with a reference value when the pointing position cannot be calculated based on the captured image;
• and
• outputting information about the tilt of the input device based on the comparing.

A system comprising at least one information processing apparatus which can communicate with an input device performing a pointing action by using an image capturing device for capturing an image of a target object, and calculate a pointing position on a screen of a display device based on the image captured by the image capturing device, wherein the input device comprises a motion-attitude detector configured to detect a motion or an attitude of the input device, the system comprising:

• a processor configured to:
• calculate a tilt value indicating a tilt of the input device using a result of detection by the motion-attitude detector;
• determine whether or not the pointing position can be calculated based on the image captured by the image capturing device;
• compare the calculated tilt value with a reference value when the pointing position cannot be calculated;
• and
• output information about the tilt of the input device, depending on a result of comparison.
