If a virtual object in a virtual environment represented by a stereo vision system could be touched by a user with some tactile feeling on his/her fingertip, the sense of reality would be heightened. To create a visual impression as if the user were directly pointing to a desired point on a virtual object with his/her own finger, we need to align virtual space coordinates and physical space coordinates. Also, if there is no tactile feeling when the user touches a virtual object, the virtual object would seem to be a ghost. Therefore, a haptic interface device is required to give some tactile sensation to the user. We have constructed such a human-computer interaction system in the form of a simple virtual reality game using a stereo vision system, a vibro-tactile device module, and two position/orientation sensors.

In this paper, we determine the design criteria of haptic device considering the human haptic system and determine the design specifications. We developed a new 2DOF haptic device based on the specifications. It has the wide workspace, statically-balanced, constant inertia matrix, well-conditioned Jacobian matrix and so on. There also is not singularity point within workspace of the device. We show that it has better performance than other 2DOF haptic device in the many aspects.

본 논문에서는 주관적 3D quality of experience (QoE) 평가에 적합한 IACQE (Interactive Assistance Continuous Quality Evaluation) 방법을 제안한다. 이 방법은 크게 3D 평가 영상이 재생되는 디스플레이와 평가 도구사이의 device interaction, 평가 도구와 평가 참여자사이의 human interaction process로 구성된다. Device interaction process는 무선 네트워크 프로토콜 (WLAN and WiFi)을 통해 3D 디스플레를 동작시키는 서버와 평가 도구 사이의 정확한 동기화 및 평가결과 기록 등의 작업을 수행하며, human interaction process는 평가 도구로 사용하는 tablet-pc의 촉각, 시각, 청각적인 자극을 통해 기존의 주관적 3D QoE 평가에서 나타날 수 있는 문제점들을 최소화 한다.

This paper discusses the gereral principles to be considered in the design of usef interfaces of graphics packages and presents a top-down design process in systematic way. The effective and convenient user interfaces are analyzed based on human factors criteria and we discuss the properties and application requirements of typical interaction techniques which support primitive tasks. The choice of an interaction technique has a set of input device prerequisites to be met.

Human body motion is a non-verbal part for interaction or movement that can be used to involves real world and virtual world. In this paper, we explain a study on natural user interface (NUI) in human hand motion recognition using RGB color information and depth information by Kinect camera from Microsoft Corporation. To achieve the goal, hand tracking and gesture recognition have no major dependencies of the work environment, lighting or users' skin color, libraries of particular use for natural interaction and Kinect device, which serves to provide RGB images of the environment and the depth map of the scene were used. An improved Camshift tracking algorithm is used to tracking hand motion, the experimental results show out it has better performance than Camshift algorithm, and it has higher stability and accuracy as well.

In network human-robot interaction, human can access services of a robot system through the network The communication is done by interacting with the distributed sensors via voice, gestures or by using user network access device such as computer, PDA. The service organization and exploration is very important for this distributed system. In this paper we propose a new agent-based framework to integrate partners of this distributed system together and help users to explore the service effectively without complicated configuration. Our system consists of several robots. users and distributed sensors. These partners are connected in a decentralized but centralized control system using agent-based technology. Several experiments are conducted successfully using our framework The experiments show that this framework is good in term of increasing the availability of the system, reducing the time users and robots needs to connect to the network at the same time. The framework also provides some coordination methods for the human robot interaction system.

This article shows a set of physical information fusion IoT systems that we designed for smart buildings. Its essence is a computer system that combines physical quantities in buildings with quantitative analysis and control. In the part of the Internet of Things, its mechanism is controlled by a monitoring system based on sensor networks and computer-based algorithms. Based on the design idea of the agent, we have realized human-machine interaction (HMI) and machine-machine interaction (MMI). Among them, HMI is realized through human-machine interaction, while MMI is realized through embedded computing, sensors, controllers, and execution. Device and wireless communication network. This article mainly focuses on the function of wireless sensor networks and MMI in environmental monitoring. This function plays a fundamental role in building security, environmental control, HVAC, and other smart building control systems. The article not only discusses various network applications and their implementation based on agent design but also demonstrates our collaborative information fusion strategy. This strategy can provide a stable incentive method for the system through collaborative information fusion when the sensor system is unstable in the physical measurements, thereby preventing system jitter and unstable response caused by uncertain disturbances and environmental factors. This article also gives the results of the system test. The results show that through the CPS interaction of HMI and MMI, the intelligent building IoT system can achieve comprehensive monitoring, thereby providing support and expansion for advanced automation management.

유비쿼터스 컴퓨팅 환경이 발달하면서 홈네트워크 환경의 사용자 상황을 쉽게 인식하고 사용자의 상황 정보에 따라 좀 더 지능적인 서비스를 제공 할 수 있게 되었다. 지능적 서비스를 효과적으로 구현하기 위해서는 상황 정보를 객관적으로 표현할 수 있어야 한다. 상황 정보는 개체의 상황을 특성화 하는데 사용 될 수 있는 정보를 의미한다. 본 논문에서는 홈네트워크 서비스를 효과적으로 제공하기 위하여 상태 정보를 User context, Device context, Proximity(유저와 장치간의 거리) context로 분류하고, 그 상황 정보를 효과적으로 표현할 수 있는 XML기반의 HIML(Human Interaction Markup Language)을 설계하였다. 또한 설계된 HIML 문서를 통해 다양한 플랫폼에서 작동하고, 여러 가전기기와 센서장비들의 상호작용이 가능하게 하는 미들웨어를 설계하고 그 기능을 실험하였다.

Objective: This study aims to implement a non-contact gesture-based interface for presentation purposes and to analyze the effect of the proposed interface as information transfer assisted device. Background: Recently, research on control device using gesture recognition or speech recognition is being conducted with rapid technological growth in UI/UX area and appearance of smart service products which requires a new human-machine interface. However, few quantitative researches on practical effects of the new interface type have been done relatively, while activities on system implementation are very popular. Method: The system presented in this study is implemented with KINECT$^{(R)}$ sensor offered by Microsoft Corporation. To investigate whether the proposed system is effective as a presentation support tool or not, we conduct experiments by giving several lectures to 40 participants in both a traditional lecture room(keyboard-based presentation control) and a non-contact gesture-based lecture room(KINECT-based presentation control), evaluating their interests and immersion based on contents of the lecture and lecturing methods, and analyzing their understanding about contents of the lecture. Result: We check that whether the gesture-based presentation system can play effective role as presentation supporting tools or not depending on the level of difficulty of contents using ANOVA. Conclusion: We check that a non-contact gesture-based interface is a meaningful tool as a sportive device when delivering easy and simple information. However, the effect can vary with the contents and the level of difficulty of information provided. Application: The results presented in this paper might help to design a new human-machine(computer) interface for communication support tools.
