Game apparatus, storage medium, and computer program that adjust level of game difficulty

A game apparatus for executing a predetermined game, comprising:

• a storage unit that stores one or more predetermined assigned movements, the predetermined assigned movements having a predetermined timing;
• a movement detection unit that detects one or more concurrent movements of a player;
• a timing notice unit that indicates the predetermined timing of the predetermined assigned movements by a visual effect or an auditory effect;
• a timing decision unit that decides whether a timing of the concurrent movements of the player corresponds to the predetermined timing for the predetermined assigned movements and decides that the timing of the concurrent movement of the player does not correspond to the predetermined timing for the predetermined assigned movements if the timing of the concurrent movements of the player does not fall within an allowable range of the predetermined timing for the predetermined assigned movements;
• a movement specifying unit that specifies a correspondence between the concurrent movements of the player and the predetermined assigned movements based on the decision by the timing decision unit;
• a similarity decision unit that determines a similarity between the concurrent movements of the player and the predetermined assigned movement based on at least one of a direction, a magnitude and a speed of the concurrent movements of the player;
• and
• a game level setting unit that sets a game level of difficulty, wherein at least one of a tempo of the predetermined assigned movements, a type of the predetermined assigned movements and a degree of similarity is changed based on the game level of difficulty.

A storage medium in a computer having a computer-executable program recorded thereon, the computer being provided with an image sensor that is capable of concurrently detecting movements of a player in a detection range for a single view, the program comprising:

• a program code that executes a predetermined game;
• a program code that detects a movement of the player in each of a plurality of detection regions from a detection result of the image sensor, the detection range for the single view being divided to form the plurality of detection regions;
• a program code that determines a similarity between the movement of the player and a predetermined assigned movement for each detection region based on at least one of a direction, a magnitude and a speed of the movement of the player, the predetermined assigned movement being set in accordance with the detection region in advance;
• and
• a program code that sets a game level of difficulty, wherein at least one of a tempo of the predetermined assigned movement, a type of the predetermined assigned movement and a degree of similarity is changed based on the game level of difficulty.

A storage medium having a computer program for performing the steps of:

• executing a predetermined game;
• detecting a movement of a player in each of a plurality of detection regions from a detection result of an image sensor that is capable of concurrently detecting movements of the player in a detection range for a single view, the detection range for the single view being divided to form the plurality of detection regions;
• determining a similarity between the movement of the player and a predetermined assigned movement for each detection region based on at least one of a direction, a magnitude and a speed of the movement of the player, the predetermined assigned movement being set in accordance with the detection region in advance;
• and
• setting a game level of difficulty, wherein at least one of a tempo of the predetermined assigned movement, a type of the predetermined assigned movement and a degree of similarity is changed based on the game level of difficulty.

• a movement detection unit that detects a movement of the player in each of a plurality of detection regions from a detection result of the image sensor, the detection range for the single view being divided to form the plurality of detection regions;
• a movement specifying unit that specifies one or more specified detection regions for the concurrent movements of the player based on at least one of a direction, a magnitude and a speed of each of the movements of the player;
• a similarity decision unit that determines a similarity in each specified detection region between the concurrent movements of the player and the predetermined assigned movements corresponding to the specified detection region based on at least one of the direction, the magnitude and the speed of the concurrent movement of the player;
• and
• a game level setting unit that sets a game level of difficulty, wherein at least one of a tempo of the predetermined assigned movements, a type of the predetermined assigned movements and a degree of similarity is changed based on the game level of difficulty.

A game apparatus for executing a predetermined game, comprising:

• a storage unit that stores one or more first movement vectors of a predetermined assigned movement;
• a movement detection unit that detects a movement of a player;
• a movement vector calculation unit that calculates one or more second movement vectors for the movement of the player based on at least one of a direction, a magnitude and a speed of the movement of the player;
• and
• a similarity decision unit that decides a similarity between the first movement vectors and the second movement vectors.
