The purpose of this study is to examine the effect of force feedback on video gamers' performance with two different types of game controllers, and to verify users' consistency on their perceptions of force feedback effect and their actual performances in video games. 42 qualified players' records on a driving video game were analyzed in this study. This study shows 1) the force feedback effect in video games depends on the type of game controllers, 2) there is inconsistency between gamers' perception on the force feedback effect and their actual performances with the force feedback effect, and 3) emotional pleasure (fun factor) plays a big role in gamers' performances.

The sony Eytoy is developed on Playstation 2 using webcam for detecting human. A user see his appearance in television and become real gamer in the game. It is very different interface compared with ordinary video game which uses joystick. Although Eyetoy already was made for commercial products but the interface method still is interesting and can be added with many techniques like gesture recognition. In this paper, we have developed game interface with image processing for human hand and face detection and with game graphic module. And we realize one example game for busting balloons and demonstrated the game interface abilities. We will open this project for other developers and will be developed very much.

In vision-based interfaces for video games, gestures are used as commands of the games instead of pressing down a keyboard or a mouse. In these Interfaces, unintentional movements and continuous gestures have to be permitted to give a user more natural interface. For this problem, this paper proposes a novel gesture spotting method that combines spotting with recognition. It recognizes the meaningful movements concurrently while separating unintentional movements from a given image sequence. We applied our method to the recognition of the upper-body gestures for interfacing between a video game (Quake II) and its user. Experimental results show that the proposed method is on average $93.36\%$ in spotting gestures from continuous gestures, confirming its potential for a gesture-based interface for computer games.

The arcade gun has been a popular game controller in the video game market from the 1970s. The arcade gun, which is used partially in game centers and domestic games, recently is utilized as the interface for the interactive system and tangible media. On the other hand, the existing arcade gun has limits on hardware so it is unsuitable for wide screens. In addition, being platform-dependent, it is inapplicable to various types of content as a single module. This study suggests a correction algorithm that establishes an arcade gun system based on an infrared camera to solve those drawbacks and apply to possibly numerous surroundings.

This paper introduces an efficient and satisfactory search interface that enables users to browse and find the video data they want from a massively huge video database widely used in various multimedia environment. The target user group is information analysts at US defense industry or governmental intelligence agencies whose job is to identify a certain person from a lot of video footage taken from CCTV(Closed-circuit Television) cameras. For the first user test, we suggested the CAVE-like virtual reality interface to be the most optimal for the tasks we designed for, so we compared this interface with desktop interface. The softwares and database developed and optimized for each task were used in this user test. For the second user test, we researched on what input devices would be most optimal for enhancing efficiency of search task in the CAVE-like virtual reality system. Especially we focused our effort on measuring the effectiveness and user satisfaction of three different types of devices that embody gestural interface input system that encourages users' ergonomic control of the interface. We also measured the time consumed for performing each task to find out the most efficient input device among the ones tested.

With the development of tangible interface in recent years, the interest in interactive exercise games to improve health-related physical fitness has been increased. We believe that this kind of serious game should provide not only motion sensing of the action required to play sports but also a specific effectiveness of exercise. This paper will show how a serious exercise game affects theirs heart rate and preference. For the experiments, we used an exercise game named GalaxyBike for aerobics exercise which is developed by the Interaction Media Research Center of Hoseo University. In the experiments, players' heart rate was measured during the warming-up, exercise and cooling-down periods by a wireless heart-rate measuring instrument. After they played the exercise game, a survey was conducted to see how they like this serious exercise game. The findings of the study suggest that the serious exercise game providing both video game and exercise would make a contribution to the improvement of health-related physical fitness since it serves to increase the heart rate and motivation.

This paper describes a monocular PSD-based motion capture sensor to employ with commercial video game systems such as Microsoft's XBOX and Sony's Playstation II. The system compact, low-cost, and only requires a one-time calibration at the factory. The system includes a PSD(Position Sensitive Detector) and active infrared (IR) LED markers that are placed on the object to be tracked. The PSD sensor is placed in the focal plane of a wide-angle lens. The micro-controller calculates the 3D position of the markers using only the measured intensity and 2D position on the PSD. A series of experiments were performed to evaluate the performance of our prototype system. From the experimental results we see that the proposed system's compact size, low-cost, ease of installation, and high frame rates are suitable for high speed motion tracking in games.

This study investigated the types and characteristics of arcade games that have marked the beginning of the game industry. Arcade game equipment have been largely evolved from 'mechanical arcade game equipment' to 'electro-mechanical arcade game equipment', and to 'video arcade game equipment' In these evolution processes, arcade games have had unique characteristics distinct from other game platforms. These characteristics included the properties of 'space' and 'time', 'original form of gameplay', 'simple interface' and 'performance feasibility.' The recent stagnation of arcade games was due to the fact that the characteristics of arcade games started to lose their unique characteristics since these were also spread to other platform of games.

DirectX Graphics plays the role of hardware independent 3 dimensional drawing interface for 3 dimensional video display. However the APIs in DirectX Graphics provide not only small improvement in velocity in the lowest level but also unstable performance of velocity according to their usages. In this paper, we present the structure of 3D game engine of efficient performance and describe functions and implementational features of game engines for an efficient 3D rendering in the environment of DirecX Graphics.

This study conducted a case study using various platforms centered on a tennis game to examine what forms the movements of a game player had when they were abstracted in the game. In particular, it summarized the forms of the player's experience that could be attained from the abstracted tennis actions into the 4 types: movement, swing, direction & intensity, and skill; and observed and schematized them in the early video games, console games, mobile games, Gesture recognition games, and wearable games. In conclusion, the development of technology offers the players with greater experience. For example the change of the platform of simple games of pressing buttons into swinging. Furthermore, the study found a consistency in the context even though the difference of action was slightly found by the interface.
