Information processing apparatus and storage medium storing information processing program
First Claim
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.

Abstract
An information processing apparatus can communicate with an input device comprising an image capturing means for capturing an image of a target object, and calculates a pointing position on a screen of a display device based on the image captured by the image capturing means. The input device comprises a motion detecting means for detecting a motion of the input device. The information processing apparatus calculates a tilt value indicating a tilt of the input device using a result of detection by the motion detecting means. It is determined whether or not the pointing position can be calculated based on the image captured by the image capturing means. When it is determined that the pointing position cannot be calculated, the calculated tilt value is compared with a predetermined reference value. The user is notified of information about the tilt of the input device, depending on a result of the comparison.
