Since fundamentally though we only need to generate viewpoints for known observers, the classical approach to render all views at once is wasteful in terms of GPU resources and limits the scale of an auto-stereoscopic display. We present a technique that reduces GPU consumption when using an auto-stereoscopic displays by giving the display a context awareness of its observers. The technique was first applied to the Looking Glass device on the Unity3D platform. Rather than rendering 45 different views at the same time, for each observer, the framework only requires six views that are visible to both eyes based on the tracked eye positions. Given the current specifications of this device, the framework helps save 73% GPU consumption for Looking Glass if it was to render a 8K X 8K resolution scene, and the saved GPU consumption increases as the resolution increases. This technique can be applied to reduce future GPU requirements for auto-stereoscopic displays in the future.","PeriodicalId":216038,"journal":{"name":"ACM SIGGRAPH 2019 Posters","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130961661","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}

This method is useful for various VR use cases because it provides feedback without disturbing users' movement. In our experiment, we presented haptic feedback of sine waves which were dynamically modulated according to direction and distance between a player and a target. These waves were presented to both sides of the users' necks independently. As a result, players could reach invisible targets and immediately know they had reached the targets. The proposed algorithm allows the neck to become as important a receptive part of body as eyes, ears, and hands.","PeriodicalId":216038,"journal":{"name":"ACM SIGGRAPH 2019 Posters","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114725427","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}

We propose a refiner network (RefNet) that can augment a state-of-the-art hand tracking system (BaseNet) by refining its estimations on unlabeled data. At each input depth frame, the estimations from the BaseNet are iteratively refined by RefNet using a model-fitting strategy. During this process, the RefNet adapts to the input data characteristics by incremental learning.

To develop this procedural approach, we have identified the set of rules and similarities of Second Empire houses. Our procedural approach, therefore, captures the style differences of Second Empire houses with a relatively few numbers of parameters. Using our interface, we are able to generate virtual houses in a wide variety of styles of American Second Empire architecture. We have also developed a method to break up these virtual models into slices in order to efficiently and economically 3D print them. Using this approach we have created miniatures of two landmark buildings: the Hamilton-Turner Inn in Savannah and the Enoch Pratt House in Baltimore. Note that the virtual models still provide more details because of the limited resolution of 3D printing processes.","PeriodicalId":216038,"journal":{"name":"ACM SIGGRAPH 2019 Posters","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127624161","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}
