1. A computer readable storage medium storing an information processing program executable by a computer included in an information processing apparatus which can communicate with an input device comprising an image capturing means 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 means, whereinthe input device comprises a motion detecting means for detecting a motion of the input device,the information processing program causing the computer to execute:

  • a tilt calculating step of calculating a tilt value indicating a tilt of the input device using a result of detection by the motion detecting means;

    a determination step of determining whether or not the pointing position can be calculated based on the image captured by the image capturing means;

    a comparison step of comparing the tilt value calculated by the tilt calculating step with a predetermined reference value when it is determined that the pointing position cannot be calculated; and

    a notification step of notifying a user of information about the tilt of the input device, depending on a result of the comparison step.
