By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Konami Digital Entertainment Co., Ltd. (Tokyo, JP) has been issued patent number 8740704, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Tarama, Naoki (Suita, JP); Yamamoto, Naohiro (Tokyo, JP).

This patent was filed on March 11, 2013 and was published online on June 3, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "The present invention relates to a game device, a control method for a game device, and a non-transitory information storage medium.

"There is known a game device for performing game processing by using an image (photographed image) of a player obtained by photographing the player with a camera. For example, JP 3866474 B2(JP 2001-224730 A) discloses a game device that determines an operation performed by a player by analyzing the photographed image."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "In a case where the operation performed by the player is determined based on the photographed image, processing for analyzing the image is performed, and hence it may require more time to determine the operation performed by the player than in a case where the operation performed by the player is determined based on an operation signal (for example, button depression signal) received from a general game controller. As a result, a time lag occurs between a time at which the player actually performs the operation and a time at which the game device determines that the player has performed the operation.

"For example, as described in JP 3866474 B2, in the game configured such that the player moves their body in time to an action of a character displayed on a screen, a time lag occurs between a time at which the player dances in time to the action of the character and a time at which the game device determines that the player has danced, and hence there is a problem that the player feels stressed about an improper evaluation of the game in spite of dancing correctly.

"The present invention has been made in view of the above-mentioned problem, and an object thereof is to provide a game device, a control method for a game device, and a non-transitory information storage medium therefor, which are capable of alleviating the stress placed on a player.

"In order to solve the above-mentioned problem, according to the present invention, there is provided a game device which executes a game configured such that a position of a body part of a player at a given time point is determined, including: player position information acquiring means for acquiring player position information relating to the position of the body part of the player; reference data acquiring means for acquiring reference data from means for storing the reference data, the reference data being obtained by associating information relating to a reference time point with information relating to a reference position in which the body part is to be placed at the reference time point; guide showing means for showing the player the reference time point and the reference position based on the reference data; first determination means for determining whether or not the reference position and the position of the body part of the player indicated by the player position information acquired at a first determination time point, which is a time point set based on the reference time point and which is earlier than the reference time point, satisfy a first criterion relating to a positional displacement between the position of the body part and the reference position; second determination means for determining whether or not the reference position and the position of the body part of the player indicated by the player position information acquired at a second determination time point, which is a time point set based on the reference time point and which is later than the first determination time point, satisfy a second criterion which is a criterion relating to the positional displacement between the position of the body part and the reference position and which indicates a smaller positional displacement than the positional displacement indicated by the first criterion; first processing execution means for performing processing relating to effects on the game based on a determination result from the first determination means; and second processing execution means for performing processing relating to evaluation of the player based on a determination result from the second determination means.

"Further, according to the present invention, there is provided a control method for a game device, which executes a game configured such that a position of a body part of a player at a given time point is determined, including: a player position information acquiring step of acquiring player position information relating to the position of the body part of the player; a reference data acquiring step of acquiring reference data from means for storing the reference data, the reference data being obtained by associating information relating to a reference time point with information relating to a reference position in which the body part is to be placed at the reference time point; a guide showing step of showing the player the reference time point and the reference position based on the reference data; a first determination step of determining whether or not the reference position and the position of the body part of the player indicated by the player position information acquired at a first determination time point, which is a time point set based on the reference time point and which is earlier than the reference time point, satisfy a first criterion relating to a positional displacement between the position of the body part and the reference position; a second determination step of determining whether or not the reference position and the position of the body part of the player indicated by the player position information acquired at a second determination time point, which is a time point set based on the reference time point and which is later than the first determination time point, satisfy a second criterion which is a criterion relating to the positional displacement between the position of the body part and the reference position and which indicates a smaller positional displacement than the positional displacement indicated by the first criterion; first processing execution step of performing processing relating to effects on the game based on a determination result obtained in the first determination step; and second processing execution step of performing processing relating to evaluation of the player based on a determination result obtained in the second determination step.

"Further, according to the present invention, there is provided a program for causing a computer to function as a game device, which executes a game configured such that a position of a body part of a player at a given time point is determined, the game device including: player position information acquiring means for acquiring player position information relating to the position of the body part of the player; reference data acquiring means for acquiring reference data from means for storing the reference data, the reference data being obtained by associating information relating to a reference time point with information relating to a reference position in which the body part is to be placed at the reference time point; guide showing means for showing the player the reference time point and the reference position based on the reference data; first determination means for determining whether or not the reference position and the position of the body part of the player indicated by the player position information acquired at a first determination time point, which is a time point set based on the reference time point and which is earlier than the reference time point, satisfy a first criterion relating to a positional displacement between the position of the body part and the reference position; second determination means for determining whether or not the reference position and the position of the body part of the player indicated by the player position information acquired at a second determination time point, which is a time point set based on the reference time point and which is later than the first determination time point, satisfy a second criterion which is a criterion relating to the positional displacement between the position of the body part and the reference position and which indicates a smaller positional displacement than the positional displacement indicated by the first criterion; first processing execution means for performing processing relating to effects on the game based on a determination result from the first determination means; and second processing execution means for performing processing relating to evaluation of the player based on a determination result from the second determination means.

"Further, the information storage medium according to the present invention is a non-transitory computer-readable information storage medium having the above-mentioned program recorded thereon.

"According to the present invention, it is possible to alleviate the stress placed on the player.

"Further, according to one aspect of the present invention, the first determination means determines whether or not the first criterion is satisfied by determining whether or not the position of the body part of the player indicated by the player position information acquired at the first determination time point is included in a first determination area set based on the reference position, and the second determination means determines whether or not the second criterion is satisfied by determining whether or not the position of the body part of the player indicated by the player position information acquired at the second determination time point is included in a second determination area which is an area set based on the reference position and which is covered by the first determination area.

"Further, according to one aspect of the present invention, the game includes a game configured such that the player aims to perform the same action as a character displayed on display means, and the game device further includes means for acquiring information relating to a change direction of the body part of the character within a period set based on the reference time point, and means for changing the first determination area and the second determination area based on the acquired change direction.

"Further, according to one aspect of the present invention, the first determination means determines whether or not the first criterion is satisfied based on whether or not a number of body parts, whose positional displacement amount between the position of the body part of the player indicated by the player position information acquired at the first determination time point and the reference position is within a reference range, is within a first reference range, and the second determination means determines whether or not the second criterion is satisfied based on whether or not a number of body parts, whose positional displacement amount between the position of the body part of the player indicated by the player position information acquired at the second determination time point and the reference position is within the reference range, is within a second reference range whose lower limit value is larger than a lower limit value of the first reference range."
