Whether or not an angular velocity detected by an angular velocity sensor is used for a game process is determined, and a difficulty level of a game to be subjected to a game process is set so as to vary depending on whether the angular velocity is determined to be used or the angular velocity is determined not to be used. When the angular velocity is determined not to be used, a process of specifying a motion direction of an input device is performed by using acceleration detected by an acceleration sensor, whereas when the angular velocity is determined to be used, at least a part of the process of specifying the motion of the input device is performed by using the angular velocity detected by the angular velocity sensor. Accordingly, based on the specified motion direction, the game process is performed while the set difficulty level is applied.

PROBLEM TO BE SOLVED: To provide a game system which does not make a player have the feeling of incompatibility or an unpleasant feeling even in the case of the game system wherein it is hard for the player to instantaneously obtain reaction to the input operation of himself/herself such as the game system for playing a game by a controller provided with an acceleration sensor. SOLUTION: When the value of an acceleration detected by the acceleration sensor becomes a threshold or larger, the processing of outputting confirmation sound from the speaker of a controller is performed, and an effective sound corresponding to the operation of a player character is outputted from the speaker of a television.

PROBLEM TO BE SOLVED: To provide a game device capable of preventing an object to be operated from getting into motion unintended by a player.SOLUTION: A game device (10) plays a game in which at least one of the object to be operated by the player and multiple objects or characters moves in a game space. A numerical value information obtaining means (51) obtains numerical value information corresponding to the motion of the player. A control means (52) makes the object to be operated get into motion corresponding to the case where the position relationship with the object to be operated and the object or character is a first position relationship when the numerical value information satisfies a condition. A condition changing means (55) changes the condition based on the position relationship between the object to be operated and the object or character. The condition changing means (55) makes such a setting that the numerical value information becomes difficult to satisfy the condition in the case where the position relationship between the object to be operated and the object or character is a second position relationship compared to the condition in the case where the object to be operated and the object or character is a first position relationship.

By repeatedly obtaining acceleration data, a gravity direction acceleration acting in a gravity direction of a housing and a horizontal direction acceleration acting in a horizontal direction perpendicular to the gravity direction are calculated. By using a first coefficient, a first step count in accordance with a change in the gravity direction acceleration is calculated and by using a second coefficient which is different from the first coefficient, a second step count in accordance with a change in the horizontal direction acceleration is calculated. Based on a predetermined condition, one of the first step count and the second step count is selected as a user's step count.

SOLUTION: The orientation calculation apparatus includes gravitational vector calculation means, first correction means, second correction means, and third correction means. The gravitational vector calculation means calculates a gravitational vector based on an angular rate represented by angular rate data. The first correction means corrects the gravitational vector so as to approach at a first rate a direction of an acceleration vector represented by acceleration data. The second correction means corrects the gravitational vector so as to approach at a second rate a gravitational direction estimated based on a relationship between the acceleration data and the angular rate data at a second rate, the relationship being predefined for the input device making a predetermined motion. The third correction means corrects the gravitational vector so as to approach at a third rate an average of the acceleration vectors during a predetermined period. COPYRIGHT: (C)2011,JPO&INPIT
