The goal of this research is to realize the expression of a kinetic artwork or interactive artwork such as waving tentacles of sea anemones. At present, soft actuators that bend in multiple directions have been developed. However, these each have a complex structure or are expensive. To realize the expression of waving tentacles we need a large number of actuators. Therefore, we developed a budget actuator with a simple structure. Previously, we have introduced three motion patterns for controlling a SMA actuator that can bend in three directions and an experimental system with 9 actuators [Nakayasu 2014]. In this paper, we introduce an experimental system with 64 actuators that react to a hand's movement via an optical flow algorithm.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122376424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our work focuses on representation of data relevant to natural hazards scenarios. Although visualization choices can be made on maps, their fundamental representation is recognizably the same as what it was hundreds of years ago. Video representations can improve on this by incorporating temporal information about disasters in a linear manner. Video still has restrictions though, as they require predetermined decisions about viewpoint and what information is presented at any time-point in the narrative. The current work aims to incorporate the strengths of these methods and expand on their impact. We create a highly customizable visualization tool that incorporates the Unity 3D game engine with scientific layers of information about natural hazards. We discuss the development of proof-of concept work in the bushfire hazard domain here.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122907241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas, most of them are created manually. Then automatic facial animation system for dancing character will be useful to create dance movies and visualize impressions effectively. Therefore, we address the challenging theme to estimate dancing character's emotions (we call \"dance emotion\"). In previous work considering music features, DiPaola et al. [2006] proposed music-driven emotionally expressive face system. To detect the mood of the input music, they used a hierarchical framework (Thayer model), and achieved to generate facial animation that matches music emotion. However, their model can't express subtleties of emotion between two emotions because input music divided into few moods sharply using Gaussian mixture model. In addition, they decide more detailed moods based on the psychological rules that uses score information, so they requires MIDI data. In this paper, we propose \"dance emotion model\" to visualize dancing character's emotion as facial expression. Our model is built by the coordinate information frame by frame on the emotional space through perceptional experiment using music and dance motion database without MIDI data. Moreover, by considering the displacement on the emotional space, we can express not only a certain emotion but also subtleties of emotions. As the result, our system got a higher accuracy comparing with the previous work. We can create the facial expression result soon by inputting audio data and synchronized motion. It is shown the utility through the comparison with previous work in Figure 1.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128569225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a general and unbiased rendering technique that can easily handle diffuse and glossy surfaces. To trace light paths, most of existing path tracers rely on surface BRDFs for directional sampling. This works well for glossy appearance, but tends to be not effective for diffuse surfaces because in such cases, the rendering integral is mostly driven by the incoming radiance distribution, not the BRDFs. Therefore, with the same number of samples, it is more favorable to sample the incoming radiance distribution to achieve better effectiveness for diffuse scenes. [Vorba et al. 2014] addressed this sampling problem by using photons to estimate incoming radiance distributions which can then be compactly represented using Gaussian mixture functions.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128280155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With such many photos captured from the members belonging to a social network, [Yin et al. 2014] proposed to utilize the social context from the mobile devices, e.g., geo-tag from the GPS sensor, to help a user to capture better photos via a mobile device. Using the geo-tags of a photo and the analysis of the image content to construct a 3D model of a scene has been developed since the Photo Tourism [Snavely et al. 2006] project. The scene reconstruction scheme proposed by [Snavely et al. 2008] can visualize the photos in a 3D environment according to the photos collected from the social members. In addition, [Szeliski et al. 2013] indicated that it is a natural way to navigate the images from the social media sites in a 3D geo-located context. Therefore, for multimedia visualization with a natural and immersive 3D user experience in a tech-art gallery, we propose a 3D social media browsing system to allow users to use motion-sensing devices to interactively navigate the social photos in a virtual 3D scene constructed from a real physical space.","PeriodicalId":432851,"journal":{"name":"SIGGRAPH Asia 2015 Posters","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115744959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
