최근 홈로봇에 대한 관심이 인공지능의 발전과 함께 급증하고 있다. 단순히 대화가 가능한 로봇이 아니라 소니의 아이보와 같은 펫로봇 형태를 비롯해 교육, 엔터테인먼트, 안내, 청소와 같은 각기의 세부적인 기능에 특화되어 있는 로봇들이 속속들이 우리 앞에 나타나고 있다. 한편, 클라우드기반의 인공지능 알고리즘과 음성인식을 이용한 AI스피커가 단순히 소리를 전달하는 기능을 뛰어넘어 명령을 알아 듣고 이를 실행하거나 이에 대한 답을 제공하는 기기로 진화하고 있다. 이러한 기능의 변화는 텍스트에서 그래픽유저인터페이스로 진화된 MMI(Man-Machine Interface)의 새로운 세대를 예고하고 있다. 본 연구에서는 홈로봇의 현황과 홈로봇에 적용될 ABI(Audio Base Interface, 음성기반인터페이스)로서 AI스피커에 대해서 고찰하고 있다.

Universal design is defined as the design process of products and environments usable by all people to the greatest extent possible, without the need for adaptation or specialized design. The benefits of universal design have been promoted primarily through illustrative ‘success stories’of public, residential and occupational environments and products. While case examples may be informative, they may unfortunately be limited in terms of generality to other designs or tasks. Therefore, design methods and criteria that can be applied systematically in a range of situations to encourage universal design are needed. In addition, the seven principles of universal design are intended to guide the design process. The principles provide a framework that allows a systematic evaluation of new or existing designs and assists in educating both designers and consumers about the characteristics of more usable products and environments. However, exactly how these principles are incorporated into the design process has beenleft up to the designer. Since the introduction of universal design, designers have become familiar with the principles of universal design, and they have developed many products based on universal design. However, the principles of universal design are qualitative, which means designers cannot quantitatively evaluate their designs. Some have worked to develop more systematic ways to evaluate products and environments by providing design guidelines for each of the principles. However, recommendations have not yet been made regarding how to integrate performance measures of universal design into the product design process before the product is mass produced. Furthermore, there are sets of requirements regarding each user group that has different age and ability. Consequently, there is an urgent need for design methods, based on a better understanding of age and ability related factors, which will lead to a universally designed product or environment. The authors have proposed the PSD (Preference Set-Based Design) method that can generate a ranged set of feasible solutions (i.e., robust and flexible solution set) instead of single point solution that satisfies changing sets of design targets. The objective of this paper is to develop a general method for systematically supporting the universal design process. This paper proposes the applicability of PSD method to universal design. Here, the proposed method is successfully illustrated with a universal design problem.

At present, the significance of a new manufacturing system that can shift from ‘mass production’ and consider life cycles of a product is pointed out and extremely expected. In such a situation, it is recognized that the modular design, often called ‘unit design,’ is the important design methodology which realizes the new production system enabling ‘cost reduction,’ ‘flexible production of a multi-functional artifact,’ ‘settlement of an environmental issue,’ and so on. A module (unit) of a product is generally defined as ‘the parts group made into the sub-system from a certain specific viewpoint.’ So far, there have been many researches related to the modular design. However, they are often limited to a certain viewpoint (objective). This paper proposes a simple but effective method for multi-objective modular design. In the proposed method, a new design metric, called similarity index, is proposed to evaluate the modular design candidates from the multiple viewpoints.

본 연구는 회수 가능한 플라스틱 다단상자에 물류분야에서 주로 이용되는 UHF대역(900MHz)의 RFID 기술을 응용하기위해 플라스틱 다단상자에 금속 등의 내용물에 따라 인식률에 미치는 영향에 대해 논의 하고 RFID 칩의 삽입위치를 제안한다. 현재 수출용 물류에 사용되는 박스는 일회용 목재 팔레트를 이용 해 수출을 한 뒤 폐기하고 있는 실정이다. 일회용 목재 팔레트를 이용하는 수출업체는 폐기비용 발생으 로 인해 물류비가 증가하며 이는 가격경쟁력 면에서 뒤처지는 문제점뿐만 아니라 목재라는 특성상 수출 시 방역 및 위생문제에 노출, 외부 충격으로 인한 상자 및 상품의 파손위험 등의 단점이 있다. 많은 기업들이 신제품개발, 품질개선, 원가절감 등에 힘쓰고 있지만, 이들 중 대부분의 기업은 물류비용에 대한 인식이 결여되어있다. 따라서 본 연구에서 회수 가능한 플라스틱 다단상자에 RFID 기술을 응용해 기존의 나무상자의 단점을 해소하고 대체할 수 있는 방안을 제시하기 위해 실험을 통해 RFID 칩의 부착위 치를 실증적으로 연구하였다.
