The non-player character(NPC) either cooperates with the player character to proceed the game or fight against the game player. This paper proposes the context awareness method for the natural action control of the same NPC. The context awareness method analyzes the context information of the NPC that can be utilized in the current status and creates the actions which suit the current context automatically. The context awareness method analyzes the information value of the context elements of the NPC which occur in the current context and creates natural actions of the character by utilizing the analyzed context element information. In this experiment, average performance improved by 39% and by 8% in the context awareness method as compared to the rule-based method and information gain method, respectively.

본 논문에서는 입 바람 인터페이스를 이용하여 레이싱 게임에서의 논플레이어 캐릭터(Non-player character, NPC)를 제어할 수 있는 새로운 프레임워크를 제안한다. 대부분의 게임 콘텐츠에서 캐릭터를 제어하는 손가락을 이용한 인터페이스 방식이다. 이 같은 인터페이스의 제약은 게임의 재미를 감소시킬 뿐만 아니라 콘텐츠를 사용하는데 있어서 사용자의 몰입을 감쇠시키는 원인이 된다. 본 연구에서는 입 바람 인터페이스를 이용하여 자동차의 방향 및 속도를 제어하고 입 바람으로부터 계산된 바람의 강도를 외력으로 이용하여 NPC를 제어할 수 있는 프레임워크를 제안하여, 게임의 몰입과 재미를 향상시킨다. 본 연구는 Unity 게임 엔진에서 개발했으며 레이싱 게임뿐만 아니라 다양한 콘텐츠에서 활용할 수 있다.

포괄적인 개념에서, 게임에서 인공지능이란 PC(Player Character, 사용자에 의해서 조정되는 게임 오브젝트)를 제외한 모든 것들을 제어하기 위해 사용되는 일련의 기술이라고 정의할 수 있다. 예를 들면, PC를 둘러싸고 있는 환경, PC를 대적하거나 경쟁관계에 있는 NPC(Non-Player Character), PC에 조언을 해주는 조언자 NPC 등을 제어하고 사용자가 느끼기에 지능적이면서 실제적인 것으로 보이도록 하여 게임의 흥미를 더하기 위한 기술들이다. (중략)

본 논문에서는 실감형 Networked Virtual Environment (NVE)의 사실성 증진을 위한 Non Player Character (NPC)의 지능적 제어 프레임워크를 제안한다. 이 프레임워크는 반응의 다양성, 실시간성 그리고 NPC의 능동성면에서 기존 게임에서 사용되는 NPC 구현 기법과 차이가 있다. 기존 NPC 제어구조의 경우, 휴먼 사용자의 행동에 따른 NPC의 반응이 일정 스크립트나 규칙에 따르기 때문에 정형적이며, 또한 NPC의 반응시간에 대한 실시간성을 고려하지 않고 있다. 또한 NPC는 휴먼 사용자의 액션에 반응하는 종속적이고 수동적인 역할만을 담당한다. 제안하는 프레임워크에서는 NPC는 각자의 취향을 가지고 있어 다양한 반응과 행동양식을 보일 수 있으며, NPC의 행동 결정 시간에 어느 정도 실시간성을 부여할 수 있으며, 또한 NPC의 역할이 수동적 형태에서 벗어나 능동적으로 계획하여 행동을 실행할 수 있다. 프레임워크의 구현을 위해 SWI-Prolog의 Rule based 추론엔진과 유전자 알고리즘을 사용하였다.

Recently AI(Artificial Intelligence) is one of the issues in the on-line game, a research that a game character seems to be realistic and is progressing using AI technique. Especially NPC is an important part of the AI researches of on-line game, and it is concerned by a game player and an architect. We proposed an intelligent agent framework to implement the NPC technique after studying the NPC technique using context awareness that reacts to the PC(Player Character) actively. Also, it can be developed gradually, and apply to various application because it has the capability to of adding an agent or deleting an agent easily.

This paper explores the concept of mobile gaming platforms and changes in game play through mobile parameters, focusing on the role of role-playing mobile games through mobile parameters. As a move, the Player combines the mobile media with the game platform. The daily time of the mobile mid-dividualization is reconstructed with the principle of superposition, which affects play experience on the mobile gaming platform. The character of a mobile role-playing game plays a non-integrated play where the player is staying, rather than an avatar character, and exhibits a non-dwelling character as a residential space. Automatic battle also regenerates unused combat forces in the form of explicit integration. The experience of combat in overlapping hours serves as a visual spectacle, and the player inhabits the fighter jets.
