Anticipation effect has been used as a traditional skill to enhance the dynamic motion of the traditional 2D animation. Basically, anticipation means the action of opposite direction which performs before the real action step. In this paper, we propose the perception-based video anticipation method to guide a user's visual attention to the important region. Using the image based attention map, we calculate the visual attention region and then combine this map with temporal saliency of video. We apply the anticipation effect in these saliency regions using the blur kernel. Using our method, we can generate the dynamic video motion which has attentive guidance.

Highly sweep leading edge extensions(LEX) applied to delta wings have greatly improved the subsonic maneuverability of contemporary fighters. In this study, systematic approach by PIV experimental method within a circulating water channel was adopted to study the fundamental characteristics of induced vortex generation, development and its breakdown appearing on a delta wing model with or without LEX in terms of four angles of attack($15^{\circ},\;20^{\circ},\;25^{\circ},\;30^{\circ}$) and six measuring sections of chord length($30{\%},\;40{\%},\;50{\%},\;60{\%},\;70{\%},\;80{\%}$). Sideslip effect in case of the LEX was also studied for two sideslip(yaw) angles($5^{\circ},\;10^{\circ}$) at one angle of attack(20). Distribution of time-averaged velocity vectors and vorticity over the delta wing model were compared along the chord length direction. Quantitative comparison of the maximum vorticity featuring the induced pressure distribution were also conducted to clarify the significance of the LEX existence. Animation presentation in velocity distribution was also implemented to reveal the effect of LEX with wing vortex interaction.

The next generation Web 2.0 users are requiring a screen that satisfies visual and emotional factors regarding UI and the possibility of constant recognition about various information. To actively deal with these kinds of user demands, dual cooperation between the developer and designer is becoming more urgently needed. For this, Microsoft released Silverlight, a tool for when making a web presentation that enables persons to create a visually stunning webpage using diverse platforms and function. We applied clarity and animation to existing windows concepts, using Silverlight with which designers and developers can work together and is accessable to many development tools, and provided 3D effects to implement a Warehouse Management System.

This paper attempts to analyze Starcraft by Greimas's Carre Semiotique and the theory of structure generation semiotics, which are useful for non verbal text as well as verbal text. First, by using the Christian Metz's grand syntagma theory and principle, this study articulated the text of starcraft. As a result, it revealed that Starcraft has the axis of sense of war and has the primary sense categories of production and destruction. The sense of the Starcraft is being generated by these axis of sense and sense categories. This analysis is expected to be a stepstone for the furthermore analysis of narrative and discoursive level.

Characters' nonvocal communication plays an essential role in delivering lines and expressing emotions. A character in a game is represented with its nonvocal behavior combined with a large number of lines. In this paper, characters' nonvocal communication behaviors are categorized and analyzed. Furthermore, characters' gestures and movements are designed with bones for character gesture generation in 2D games. Besides, characters' movements are visualized. In brief, a nonvocal communication system for emotional expression of characters in 2D games is proposed.

The surface reconstruction problem from a set of wire-frame contours is very important in diverse fields such as medical imaging or computer animation. In this paper, surface triangulation method is proposed for solving the problem. Generally, many optimal triangulation techniques suffer from the large computation time but heuristic approaches may produce very unnatural surface when contours are widely different in shape. To compensate the disadvantages of these approaches, we propose a new heuristic triangulation method which iteratively decomposes the surface generation problem from a band (a pair of vertices chain) into tow subproblems from two sub-bands. Generally, conventional greedy heuristic contour triangulation algorithm, suffer from the drastic error propagation during surface modeling when the adjacent contours are different in shape. Our divide-and-conquer algorithm, called band partitioning algorithm, processes eccentric parts of the contours first with more global information. Consequently, the resulting facet model becomes more stable and natural even though the shapes are widely different. An interesting property of our method is hat it supports multi-resolution capability in surface modeling time. According to experiments, it is proved to be very robust and efficient in many applications.

Nowadays, UI(User Interface)'s main target area is getting larger from user's convenience oriented interface, to user's satisfaction oriented interface. In this study, we attempted 'Storytelling User Interface' for fulfillment of user's satisfaction. We analyzed UI in games, distinguished and clarified its effectiveness that conveys main contents and special features to its audience. The most important element in storytelling UI is 'Inherent Drama'. This was proved through the game analysis with Blizzard's 'Diablo', Sierra's 'Home world', Eden Games' 'Test Drive Unlimited', EA's 'Black And White', and Sony Entertainment's 'Eye Of Judgment'. And we divided storytelling elements into 3 pieces, Mood Design - that shows story's background, or traits, Natural Control - for user's feeling as a hero in the content, and Flow Directing - using animation, visual design and sound, etc. Via these elements, we can make the best use of background, icon, animation, every structures and flow in games. Finally, we embodied three pieces for putting in practice for effective improving interface.

In Charlotte's Web, each character motivates the other and strives for the new generation based upon motherhood. The intersection between life and death is directly and symbolically addressed as a component of the natural life cycle. Borrowing Kristeva's theory of the semiotic, the symbolic and the chora, this study investigates the dialectical oscillation between the semiotic and the symbolic and the social circumstances of subjects in signification as well as highlights the features of character growth. From a feminist perspective, herein, motherhood is translated not only as a robust foundation for relations among characters but also as an impetus for developing into a good and influential individual who embraces all organisms with care and consideration. Charlotte's Web clearly shows how the semiotic and symbolic elements of each being, united by motherhood, interact and lead to positive change. Though the world appears to consist of incompatible ingredients, they are combined. Charlotte's Web awakens the fact that their harmony makes a commitment to building a more wonderful place. It can be suggested that Charlotte's Web, where animal characters contain two tendencies of the human mind, exhibits human development proceedings.

, one of the Disney's animations, hit the 10 million audience mark for the first time in the history of animations released in Korea. not only raised the fever with its theme song, 'Let it go', as well as Elsa, Anna, and Olaf's character products but caused sensations in many ways. If so, we need to think about what kind of meaning did create in Korea to be so sensational. This study examines the value that Frozen intended to deliver and the meaning it generated by using Greimas actant model and semiotic square. From the actant model analysis on Anna and Elsa from , it was identified that Anna desired to recover her relationship with Elsa and to take summer back in Arendelle. Her desires can be interpreted as her love toward Elsa and people in Arendelle. Meanwhile, Elsa always desired freedom although she confined herself because of her ability to freeze. In other words, Elsa desired to free herself from her freezing ability by finding out how to control her ability. Such desires of Anna and Elsa were achieved by their actions of true love, and the solution of all the conflicts in was an action of true love. From the semiotic square analysis on the meaning of , it was found out that created past-oriented value with which characters tried to change their abnormal lives of the present into their normal lives of the past. The characters tried to change their present lives where freezing winter comes in the middle of summer, communication between the sisters is cut off, and people try to take advantage of the abnormal state deliberately, into the past when the sisters had a good relationship and the natural season of summer in Arendelle. The past-oriented value that tried to tell us is similar to our reality. In our reality with a lot of unbelievable news and unstable circumstances, we desire to go back to the past when we were filled with affection and hope even though our lives were tough and difficult. This sentiment must have contributed to the huge success of in Korea.
