Face masks interfere with social interactions, as they cover facial expressions that communicate personality, intentions, and emotions, and consequently impede smooth communication. This study designed and implemented a smart fashion accessory that communicates positive emotions to others, even when wearing a face mask, and evaluated its psychologi...

Although verbal information is adequate to recognize high-level psychological states, it is not compatible with passive and continuous monitoring systems. In this work, emotion-reacting wear using a passive and continuous emotion recognition system operating in real time is proposed. Specifically, a basic design of a wearable system, whose core fun...

Although 2D computer pattern making and 3D virtual prototyping are skills regarded as essential for the next generation of fashion experts, a concrete educational method for 3D virtual prototyping has yet to be established because of its high technical hurdle. This paper sought to develop an effective and creative educational program by examining t...

To reveal the actual situation of luxury fashion products in the online market, this study sheds light on dynamic pricing observed from the difference between regular and selling prices. Regular price distributions indicated the prestige of luxury fashion brands, with traditional French and Italian brands appearing in a higher rank. Two emerging lu...

We investigated author information in scientific articles by approximately 7,000 researchers for a quantitative analysis of researchers’ international mobility. From top journals, we traced the movements of more than 2,200 researchers in the research domains of robotics, computer vision and electron devices. We categorized countries’ characteristic...

The international mobility of robotics researchers is quantitatively evaluated by analyzing biographical notes accompanying journal papers. Mobility patterns illustrate that the United States, Canada, and Singapore attract robotics researchers from abroad as IQ magnets. Canada can be considered as an alternative to the United States for hosting Ira...

This study proposes a quantitative analysis of researcher mobility (i.e. transfer from one institution to another) and collaborative networks on the basis of author background data extracted from biographical notes in scientific articles to identify connections that are not revealed via simple co-authorship analysis. Using a top-ranked journal in t...

To provide further insight into globalization of research and development (R&D) activities, this study examines the nature of electrical and electronics (E&E) and information communication technology (ICT) research, and identifies the global shifts that have occurred in publication activities under the assumption of a definite correlation between r...

This study analysed the technical and publication activities of the Institute of Electrical and Electronics Engineering (IEEE), the most influential academic publisher in engineering. We first constructed an original comprehensive database of periodicals (journal and magazine) and conference proceedings published by the IEEE between 1980 and 2008,...

We organized a database of IEEE Periodicals from a period of over 15 years for quantitative and collective analysis. We found that the IEEE experienced globalization and more active international competition. East Asian countries and regions have grown dramatically and become major players in the IEEE during globalization over the last decade, and:...

Drape is a characteristic behaviour of flexible cloth, so it is important in modelling cloth. The paper introduces a novel method to model drape using a few shape parameters, predicted according to the pattern structure and mechanical properties of cloth. The technique is used to visualize the 3-D drapeability of cloth and is then extended to simul...

In this paper, we propose an impression evaluation model that can be used for retrieval of apparel data. Using impression words which evoke specific impressions and are reproducible in successive evaluations, we developed a model capable of estimating impression evaluation values from the physical features of apparel images extracted through image...

Particle models have been used for computer animation of cloth fabrication, although the relation with the mechanical properties of cloth is not clear. In particular, the non-linearity and anisotropy of the mechanical properties are important. A particle model reflecting these properties is described. The precise collision and repulsion mechanism i...

An important advantage of virtual reality technology is that real 3D objects including humans can be edited in the virtual world. In this paper, we present a technique for 3D clothes modeling based on a photo cloned human body. Photo cloning is an efficient 3D human body modeling method using a generic body model and photographs. A part segmentatio...

In this paper, collars are classified into three basic types - stand-collar, roll-collar and open-collar according to their structure. A geometrical model is established to simulate these collars and methods of drafting patterns are considered too. The collar shape was modeled as three-dimensional Bezier patches. Changing the position of control po...

An apparel product search system was proposed, in which customers can refer to products through several stores. With the system, the user can search for apparel products by inputting category information and/or Kansei measure values. A unified format of category information of apparel products suited for the search was developed. The Kansei search...

An interactive graphic human body model is developed as a hierarchical structure. Various postures of the model can be controlled through a natural language interface which is parsed by definite clause grammer and the database of the human body model made by Common Lisp Object System (CLOS). In particular, the torso component, which is the most imp...

In order to construct a CAD systm for clothing, body shape information must be obtained by measuring a human body. The silhouette method, a non-contact method, is a relatively easy one to measure the body and gives very little psychological influence on the person who is measured. This method, however, only provides a two-dimensional silhouette. In...
