System and method for virtual space-hazard assessment

A method of determining degree of hazard of a virtual space having target identifying information that identifies a target that appears in the virtual space, the method comprising:

• providing a computer and using the computer to perform each of the following steps;
• receiving a hazard rating request to rate the degree of hazard of the target, the degree being a value inputted to a terminal by the user;
• storing a table in a storage unit, the table listing the degree of hazard of the target and the target identifying information in association with each other;
• increasing the degree of hazard of the target stored in the table in the storage unit in response to the hazard rating request;
• decreasing the degree of hazard of the target stored in the table in the storage unit in response to the elapse of time;
• and
• outputting the degree of hazard stored in the table,
• wherein the target includes a place;
• and
• the computer calculates the degree of hazard of an area adjacent to the place according to the degree of hazard of the place.

An article of manufacture tangibly embodying computer readable program code, which when executed by a computer, will cause the computer to perform the following method steps:

• receiving a hazard rating request to rate the degree of hazard of the target, the degree being a value inputted to a terminal by the user;
• storing a table in a storage unit, the table listing the degree of hazard of the target and the target identifying information in association with each other;
• increasing the degree of hazard of the target stored in the table in the storage unit in response to the hazard rating request;
• decreasing the degree of hazard of the target stored in the table in the storage unit in response to the elapse of time;
• and
• outputting the degree of hazard stored in the table,
• wherein the target includes a place;
• and
• the computer calculates the degree of hazard of an area adjacent to the place according to the degree of hazard of the place.

A virtual-space hazard assessment system, for use in a virtual space having target identifying information that identifies a target that appears in the virtual space, comprising:

• a hazard-rating-request receiver for receiving a hazard rating request to rate the degree of hazard of the target, the degree being a value inputted to a terminal by the user;
• hazard storage for storing a table in which the degree of hazard of the target and the target identifying information are associated with each other;
• hazard-degree increasing means for increasing the degree of hazard of the target stored in the table in the hazard storage according to the degree of hazard received by the hazard-rating-request receiver;
• hazard-degree decreasing means for decreasing the degree of hazard stored in the table in the hazard storage with the elapse of time;
• and
• hazard-information-output instructing means for issuing an instruction to output the stored hazard information,
• wherein the target includes a place;
• and
• the assessment system further includes a proximity-hazard-degree calculator for calculating the degree of hazard of an area adjacent to the place according to the degree of hazard of the place,
• wherein the degree of hazard is determined in advance according to the place;
• and
• the proximity-hazard-degree calculator calculates the degree of hazard of the area adjacent to the place using the calculation method according to the place.
