Preparing appropriate vibrotactile signals for applications is difficult and takes much time because we need recording or directly hand tuning signals if the required signals do not exist in the database of vibrotactile stimuli. To solve these problems, TactGAN can generate signals presenting specific tactile impression based on user-defined parameters. It can also automatically generate signals presenting the tactile impression of images. It realizes the rapid designing of vibrotactile signals for application with such feedback. Users can experience the rapid designing process of the vibrotactile stimuli for specific user interfaces or specific contents on applications. TactGAN enables us to apply various vibrotactile stimuli to UI components like buttons using material kinds or tactile words, and to attach textures with vibrotactile feedback to the 3D model.","PeriodicalId":226979,"journal":{"name":"SIGGRAPH Asia 2018 Emerging Technologies","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128098421","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}

However, it has some problems in the range of motion, the resolution, and the kinds of object that can be projected. In this paper, we propose a method for realizing dynamic projection mapping by combining a high-speed/low-latency projector and a mirror-based high-speed optical axis controller. Based on high-speed visual feedback with multiple dot markers, dynamic projection mapping onto rotating/deforming objects moving in a wide range, with almost-imperceptible delay, has become possible.","PeriodicalId":226979,"journal":{"name":"SIGGRAPH Asia 2018 Emerging Technologies","volume":"285 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116295337","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}

An electrical stimulus was applied to Achilles' and tibialis anterior tendons with a kinesthetic stimulus generated by a lower limb device driven synchronously with an egocentric visual scene during virtual walking. The system works as a part of experience replication scheme that aims to receive other's physical activity. As a common bodily activity of humans, walking motion was focused. The evaluation experiment has shown that walking sensation was increased by each stimulation at a 1% significance level. In this demonstration, the user on a chair can feel as if he/she is walking in a haunted house. The user can move the upper body freely to look around with a virtual flashlight, however the lower body is possessed by the other. The user walks into the house despite the intention. The work gives the user a realistic experience which was not sufficiently generated with only a movie and sounds.","PeriodicalId":226979,"journal":{"name":"SIGGRAPH Asia 2018 Emerging Technologies","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124350876","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}

A conventional 3D zoetrope has only one object group that is illuminated by a unitary strobe light, so that the presented animation is always periodic and unchanged. Some studies [Miyashita et al. 2016; Smoot et al. 2010; Yoshida et al. 2016] and artworks, for example the Time Stratum series by Toshio Iwai, attempted to expand the range of expression of 3D zoetropes, but they did not focus on animating multiple subjects with alterations in the mutual relation between them as in the video animation.","PeriodicalId":226979,"journal":{"name":"SIGGRAPH Asia 2018 Emerging Technologies","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115406194","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}

One of the main issues accompanied by the implementations is that the odorants spread into the ambient air and it makes the user confuse what smell is presented at that time. We tried to solve this with an innovative and simple design concept of the olfactory display: installation of the air intake and inner deodorant filter. Based on the method, we include olfaction in a VR game to provide the remarkable sensation to a user with clear and various smells presentation.","PeriodicalId":226979,"journal":{"name":"SIGGRAPH Asia 2018 Emerging Technologies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117183185","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}

The purpose of this installation is to demonstrate novel visual illusions of depth and transparency for paper materials, which is induced by the conventional light projection of cast shadow patterns. Thus, this installation focuses on perceptual rather than technical aspects. Illuminating a target object, the spatial vicinity of the object is darkened to produce the visual impression of a shadow of the object. By controlling the blurriness of the cast shadow and/or spatial distance between the object and its shadow, a perceptual change in the layout of the object is induced. The audience can interactively enjoy visual experiences wherein objects and letters on a paper perceptually float in the air. We also demonstrate that it is possible to edit the material appearance of a real object by manipulating the shape of the shadow; an opaque colored paper appear to be a transparent color film floating in the air.","PeriodicalId":226979,"journal":{"name":"SIGGRAPH Asia 2018 Emerging Technologies","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115123504","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}

The mechanism of FacePush is obtained by shifting torques provided by two motors that press upon a user's face via utilization of a pulley system. FacePush can generate normal forces of varying strengths and apply those to the surface of the face. To inform our design of FacePush for noticeable and discernible normal forces in VR applications, we conducted two studies to iden- tify the absolute detection threshold and the discrimination threshold for users' perception. After further consideration in regard to user comfort, we determined that two levels of force, 2.7 kPa and 3.375 kPa, are ideal for the development of the FacePush experience via implementation with three applications which demonstrate use of discrete and continuous normal force for the actions of boxing, diving, and 360 guidance in virtual reality. In addition, with regards to a virtual boxing application, we conducted a user study evaluating the user experience in terms of enjoyment and realism and collected the user's feedback.","PeriodicalId":226979,"journal":{"name":"SIGGRAPH Asia 2018 Emerging Technologies","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128902505","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}
