- When types of communication between people are observed, one can see that communication not only consist of words but also, contextual communication consist of facial expressions and body gestures. In this study, elements that need to be considered when using light in clothes in order to express the thoughts and various emotions of the wearer and surrounding people and to design contextual interaction rather than simply for visual effects, are examined. Clothes and light are central visual elements therefore, the relationship between perception of objects through sight and emotions are examined, elements of visual language of cloths and light are examined through documentary record, elements of visual language such as shape, color, and texture of light and clothes that influence each other are classified as well as unique elements of visual elements of light such as blink speed and blink pattern, and terms that are related to the psychological effects of these elements are extracted. Based on this, using the 8 most representative human emotions which includes happiness, excitement, anger, hatred, sadness, shock, fear, and shame as standards of design, interaction design elements using clothes and light for expression of each emotion are organized in a matrix.
I. INTRODUCTION
WPC Technology, is closely linked to not only to computer
earable computer, the core field of the next generation
technology but also to machine, physics, apparel, material,
design, sensibility engineering, and psychology, and it [
When communicational behaviors of people are observed, they do not take place only through text of language. Oftentimes, people communicate more information and emotions they could not express through word using their facial expressions, body language, and actions thereby giving communication vitality and diversity.
Also in apparel, people have used clothes as a form of
communication for expressing their individuality, emotions,
status, social position, and information surrounding their
circumstances.[
Recently, as can be seen in wearable computing concept products, smart wear concept products and various studies, development of various smart fabrics and related technologies made possible use of electric equipment and materials in clothes. As a result, it became possible to see cases in which light is used in clothes for visual expression.
This study is one pertaining to interaction for exchanging people’s emotions or information between the wearer and surrounding people using light in clothes.
II. VISUAL PERCEPTION PROCESS AND PSYCHOLOGICAL
EFFECT
Clothes and light both can be said to be subjects of center of
perception. When the process of visually perceiving objects
and shapes is observed, light reflected from objects are
recognized by eyes, and this information is transmitted to the
brain from optic nerves and goes through the process of
perceiving objects and their color. From the psychological
aspect, it can be said that objects are felt rather than simply
seen.[
The shapes of cloth , colors of cloth, and textures of cloth are influenced by shapes of light, colors of light , and textures of light. we researched the elements of visual language of cloths and light are examined through documentary record to know the visual elements of clothes and light.
Emotion Color Brightness Chroma Feeling Warm Color Bright luminosity – High chroma -Stimulating brightens mood Strong feel Cold Color - Dim luminosity – makes Low chroma –
Calming melancholy peaceful feel Attention Cold colors attract Dramatic light and shade High chroma attracts more attention – attracts eyes (more attention better than than warm colors effective with greater low chroma
contrast in colors) Size Warm colors Bright luminosity – High chroma expands expand shapes, increase size (stronger objects, cold colors shrink color contrast with Low chroma – same shapes surrounding colors is size
more effective) Distance Warm color Bright luminosity – pulls High chroma – extrudes objects back objects Shortens distance, Cold colors pulls Dim luminosity – Low Chroma – back objects extrudes color (Extruding lengthens distance effect more effective with greater contrast in light and shade) Out-Line Contrast in color and shade is an effective method for stressing contours.
Warm colors make Contrast chroma contours light and emphasizes contours soft than cold colors and contrasting colors make contours more vivid than similar colors Table 2. Example of Psychological Influence Language Based on

Lights sorts and lights expressions (Blink Speed & Blink Rhythm and so on) are characteristic visual languages.
IV. EXPRESSION OF EMOTIONS USING LIGHT IN CLOTHING Anger, Annoying
The types of emotions and information for expression using
light in clothing are diverse and are difficult to classify
objectively. In this study, among the various forms of human
emotions, those that are most fundamental were extracted and
by integrating various studies, they were classified into 8
emotions that include happiness, excitement, anger, hatred,
sadness, shock, fear, and shame.[

This study is a base study for studies pertaining to interaction methods for delivering emotions and information between wearers of clothes that use light and surrounding people. In order to express emotions using light in clothing, elements of mutually complementary visual elements between clothing and light which include elements of shape, color, and texture were extracted as well as elements of characteristic source of light and method of expression of light (speed, rhythm and so on), and also extracted psychological language and expression method for each element.
Based on this, a matrix for expression of emotions using light in clothing was organized, and in the future, through scenarios of use and ideation, interactions using light in clothing will be designed and a selection among these will be made to produce a concept design of interaction that uses light in clothing.
As mentioned earlier, formation of human emotions are based on individual experience, learning, and culture, and factors of formation are also difficult to typecast. And elements of consideration for expression of emotions that could not be addressed in this study are areas that will need to be studied and supplemented. For that, in future studies, when light is used in clothing, additional elements that have psychological effects need to be identified, and through user evaluation, emotion expression matrix using light in clothing needs to be supplemented, and also, studies pertaining to direct expression through symbols or text using light also need to be conducted.
