Emojis are extensively used to convey emotional nuances non-verbally in computer-mediated communication. Previous studies have examined how emojis are used and how they change the expression of a sentence, as well as the subsequent impression of the reader. Regarding whether the writer’s emotion is understood correctly by readers, evidence shows that emojis can enhance specific emotions. However, the effects of variation in the kinds of sentence, emotion, and emoji on the shifting emotion conveyed have not been studied. In this study, we examined the various factors that affect the shift in emotions being communicated. Our results demonstrated that positive emotions can be communicated more correctly compared with negative emotions and that smiley emojis (a.k.a. emoticons) can communicate emotions more clearly compared with other kinds of emoji.

Websites of interior brands display many photographs of products that include walls, floor, and other furniture. Such photographs, known as image photographs, have much information about the brand image because the colors of walls, floor, and furniture in a photograph influence the brand image. This paper proposes a method of extracting representative colors of interior photographs in the L*u*v* color space by using a hierarchical clustering algorithm and analyzes the characteristics and differences of interior brands with color features by using model-based clustering. Our proposed method can be used to describe the common characteristics of interior image photographs and differences between six interior brands (arflex, Cassina, Fritz Hansen, IKEA, karimoku, and Muji). To measure similarity or difference between brand images, we constructed a brand image space with clusters of representative colors and obtained a relationship between six brand images.

本研究の目的は,複雑な色彩特徴を持つ画像から代表色を抽出する人の知覚過程を参考にして,データ分析に基づく代表色抽出手法を提案することである.人は画像を見たとき,画素の一つ一つを知覚するのではなく,画像全体を俯瞰して少数の代表色を知覚し,それに基づいて色彩特徴を認識する.また,画像を見て瞬時に直感的に,色彩イメージを想起したり,色彩特徴によるグループ分けをしたりする.こうした人の知覚・認知機能をコンピュータで代替する技術は未だ確立されていない.本研究では,画像に応じて代表色の色数が適応的に決まらない既往研究の問題点に着目し,画像領域分割と階層クラスタリングをあわせた方法でこの問題を解決した.また人間が抽出した代表色と提案手法が推定した代表色の距離を評価基準とし,代表色抽出法の比較評価を行った結果,従来手法より提案手法の方が統計的に人間の抽出結果に近い推定をすることが示された.

Body care motions apply a large amount of stress on caregivers' muscles and spines, so most of them suffer from low back pain. One of the major factors of low back pain is the low back muscular load to keep the deep flexion posture. This study concerned development of a suit-type back muscle supporter named "the care suit," which reduces low back load. Elastic fiber belts (support lines) are arranged on the back and leg parts of the suit. The support lines are relaxed so as not to interfere with daily trunk motion, arm motion, walking, and sitting motion, but to exert tensile force and extension moment in the deep flexion posture. The care suit is a two-piece design to improve comfort and convenience. To optimize the layout of the support lines we developed a small reel-type device to measure body surface deformation. As the result of measurement by this device and a system for posture measurement during several motions, the back support lines are arranged in an x-shape from the side neck point to the point internally dividing the Jacoby-line at a ratio of 1 to 2. The leg support lines branch at the rear face of the thigh and are attached to the apex of the patella. The maximum tension of support lines is limited by the user's shoulder pain to 140 N for males and 85 N for females. The effect of the care suit was evaluated by electromyograms of back muscles. The action potential in the deep flexion posture was 25% decreased. In comparison with the conventional corset, the effect of the care suit for back muscle was equal, but the care suit is superior in that it does not interfere with flexion motion. The lumbar joint muscular moment during a diaper change operation was calculated from body posture through a rigid body link model. The results of this calculation showed that the stored load during the operation was decreased by 30% by the care suit. Furthermore the summation of intervertebral disk compressive force was reduced by 15% during the operation. Therefore the care suit is effective for reduction of not only continuous muscular load but also spinal load. Practical use by caregivers also resulted in good evaluations as it reduced continuous muscle load for a diaper change operation, bed making operation, etc. Conclusively, the low back load during body care motions can be reduced by the care suit developed in this research. This care suit is under patent application.
