미래를 예측하는 가장 정확한 방법은 미래를 창조하는 것이다. 본 논문은 멀지않은 미래를 창조하는 것이다. 본 논문은 멀지않은 미래에 우리 앞에 놓일 기술과 제품에 대한 예측과 창조를 위하여 연구된 결과이다. 인간의 생활을 풍요롭게 할 수 있는 기술롸 제품을 인간 중심으로, 인간에게 만족스럽게 개발하기 위해서 인간의 생활 특성과 함께 기계화 인간 사이의 관계를 새롭게 정리하였다. 또 인간의 COMMUNICATION생활에서 그 비중을 급속히 증가시켜 가고 있는 Haman-Machine(Computer) Interaction에 대한 정밀한 고찰을 통하여 인간 중심의 Human-Machine Interaction 을 가능하게 할 Interface로서의 MultiMedia개념을 도출하였다. 개인의 감성은 감정과 구분되는 심리 변화로, 감정에 비하여 강도는 약하나 일상 생활에서 개인의 생각과 행동에 중요한 영향을 미친다. 감성은 외부의 감각자극에 대하여 직관적이고 반사적으로 발생되며, 개인의 생활경험과 상황에 따라 다양하게 변화된다. 제품에 대한 소비자의 욕구는 단순한 보유욕구에서 비교우위욕구, 사용성 욕구를 거쳐 감성욕구로 변환된다. 미래의 인간 생활에 필요한 기술과 제품은 인간의 COMMUNICATION생활과 감성 특성을 반영하여 감성적 MultiMedia 와 감성인터페이스의 개념으로 창조되었다.

Wearable robots are receiving great attention from the public, as well as researchers, because its motivation is to improve the quality of lives of people. Above all, complete paraplegic patients due to spinal cord injury (SCI) might be the most adequate target users of the wearable robots, because they definitely need physical assistance due to the complete loss of muscular strength and sensory functions. Furthermore, the medical care of complete paraplegics by using the wearable robots have significantly reduced the mortality rate and improved the life expectancy. The requirements of the wearable robot for complete paraplegics are actuation torque, locomotion speed, wearing sensation, robust gait stability, safety, and practicality (i.e., size, volume, weight, and energy efficiency). A WalkON Suit is the wearable robot that has satisfied the requirements of the wearable robot for complete paraplegics and participated in the powered exoskeleton race of Cybathlon 2016. In this paper, configuration of the WalkON Suit, human-machine interface, gait pattern, control algorithm, and evaluation results are introduced.

Recently, the more demand of reusable energy is globally increasing, the nationwide industry of wind power plants is more thriving. However, the level of native technology for operating wind power plants falls behind advanced countries. Thus, the most of management systems for wind power plants should be imported from the advanced countries. Additionally, advanced countries, which have possessed the controllable skills and consummate operating knowhow over decades, are blockading other countries which want to enter the market of wind power plants, and lead markets. This paper designs a prototype of HMI(Human Machine Interface) system which can effectively control and manage wind power plants.

The intelligent human-machine interface (HMI) has been developed to enhance the safety and availability of a nuclear power plant by improving operational reliability The key elements of the HMI are the large display panels which present synopsis of the plant status and the compact, digital work stations for the primary operator control and monitoring functions. The work station consists of four consoles such as a dynamic alarm console (DAC), a system information console (SIC), a computerized operating-procedure console (COC), and a safety related information console (SRIC). The DAC provides clean alarm pictures, in which information overlapping is excluded and alarm impacts are discriminated, for quick situation awareness. The SIC covers a normal operation by offering all necessary plant information and control functions. In addition, it is closely linked with the DAC and the COC to automatically display related system information under the request of these consoles. The COC aids the operator with proper emergency operation guidelines so as to shutdown the plant safely, and it also reduces his physical/mental burden by automating the operating procedures. The SRIC continuously displays safety related information to allow the operator to assess the plant status focusing on plant safety. The proposed HMI has been validated and demonstrated with on-line data obtained from the full-scope simulator for Yonggwang Units 1,2.

Voice Recognition has recently been improved with AI(Artificial Intelligence) and has greatly improved the false recognition rate and provides an effective and efficient Human Machine Interface (HMI). This trend has also been applied in the defense industry, particularly in the aviation, F-35. However, for the quality evaluation of Voice Recognition, the defense industry, especially the aircraft, requires measurable quantitative models. In this paper, the quantitative evaluation model is proposed for applying Voice Recognition to aircraft. For the proposal, the evaluation items are identified from the Voice Recognition technology and ISO/IEC 25000(SQuaRE) quality attributes. Using these two perspectives, the quantitative evaluation model is proposed under aircraft operation condition and confirms the evaluation results.

The electrical muscle stimulator (EMS) based human machine interface (HMI) free to mechanical constraint and muscle fatigue problems are proposed for force feedback in a virtual reality. The device was designed to provide force feedback up to 4.8 N and 2.6 N each to the thumb and forefingers. The main objective of the HMI is to make unnecessary mechanical structures to attach on the hand or fingers. It employs custom EMSs and an interface arranged in the forearm. In this work, major muscle groups such as extensor pollicis brevis (EPB), extensor indicis proprius (EIP), flexor pollicis longus (FPL) and flexor digitorum profundus (FDP) are selected for efficient force feedback and controlled individually. For this, a human muscular-skeletal analysis was performed and verified. The validity of the proposed multi-channel EMS based HMI was evaluated thorough various experiments with ten human subjects, interacting with a virtual environment.

Traditional tactile controls that include push buttons and rotary switches may cause significant visual and biomechanical distractions if they are located away from the driver's line of sight and hand position, for example, on the central console. Gestural controls, as an alternative to traditional controls, are natural and can reduce visual distractions; however, their types and numbers are limited and have no feedback. To overcome the problems, a driver interface combining gestures and visual feedback with a head-up display has been proposed recently. In this paper, we investigated the effect of this type of interface in terms of driving performance measures. Human-in-the-loop experiments were conducted using a driving simulator with the traditional tactile and the new gesture-based interfaces. The experimental results showed that the new interface caused less visual distractions, better gap control between ego and target vehicles, and better recognition of road conditions comparing to the traditional one.

In this paper We propose one computer interface device for handicapped people. Input signals of the interface device are movements of eyeballs and head of handicapped. The movements of the eyeballs and head are detected by an image processing system. One feature of our system is that the operator is not obliged to wear any burdensome device like glasses and a helmet. The sensing performance of the image processing of the eyeballs and head is evaluated through experiments. Experimental results reveal the applicability of our system.

The purpose of rhis research is proposing rhe sysrem which does information supporr as for a truck driver, and verifying the validity. First, it investigated by visiting the Transporr Company and interview for the present situation and the opinion on computerization from the operation administrator and truck drivers. Consequently, the problem of computerization could be found out to the present system. Next, the present system was considered. As for present machine system, human's "Choosing a function", srarts processing. Then this system is called "Function-Oriented-System". And three problems were extracted from this sysrem. As a solution of those problems, the Purpose-Oriented-System was proposed. In order to attain user's purpose, Agent that situation is perceived and works a function autonomously assumed that this system was inherent. 3D-Sceanrio-Expression was proposed as the description method of rhe task process. It consists of "Machine and Functional-Item axis", "Time axis", and "Situation-Item axis". And, the task execution process of Function-Oriented-System and Purpose-Oriented-System was compared using 3D-Sceanrio-Expression supposing the scene of truck business. As a resulr, rhe following two things could be found out. (1) The concepr of Purpose-Oriented-System that Agent is inherent is effective as siruarion correspondence machine. (2) A solid scenario can express the interaction rhar cannor be seen, in the relarion of rhe conventional Human and Machine.
