This system can recognize user speech commands, and the robot performs the task cooperatively. The system that we propose, in which passive sensation feedback and cooperation of the robot are used, highly reduces the perception of latency and the feeling of fatigue, which increases the quality of experience and task efficiency. In the demo experience, participants will be able to command the robot from individual rooms via a URL and RoomID, and they will perceive sound and visual feedback, such as images or landscapes of the campus of Tokyo Metropolitan University, from the robot as it travels.","PeriodicalId":344160,"journal":{"name":"SIGGRAPH Asia 2020 Emerging Technologies","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129982404","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}

Existing approaches are also often limited in their supported range of head motion. We introduce OmniPhotos, a novel approach for casually and reliably capturing high-quality 360° VR panoramas. Our approach only requires a single sweep of a consumer 360° video camera as input, which takes less than 3 seconds with a rotating selfie stick. The captured video is transformed into a hybrid scene representation consisting of a coarse scene-specific proxy geometry and optical flow between consecutive video frames, enabling 5-DoF real-world VR experiences. The large capture radius and 360° field of view significantly expand the range of head motion compared to previous approaches. Among all competing methods, ours is the simplest, and fastest by an order of magnitude. We have captured more than 50 OmniPhotos and show video results for a large variety of scenes. We will make our code and datasets publicly available.","PeriodicalId":344160,"journal":{"name":"SIGGRAPH Asia 2020 Emerging Technologies","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121488769","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, there are issues such as enclosing the user’s view with a display, restricting the workspace to a limited amount of flat space, or changing the visual information presented in conventional systems. In this paper, we propose “HaptoMapping,” a novel projection-based AR system, that can present consistent visuo-haptic sensations on a non-planar physical surface without installing any visual displays to users and by keeping the quality of visual information. We implemented a prototype of HaptoMapping consisting of a projection system and a wearable haptic device.

CoiLED Display consists of a strip-shaped display unit with a single row of attached LEDs, and it can represent information, after a calibration process, as it is wrapped onto a target object. The calibration required for fitting each object to the system can be achieved by capturing the entire object from multiple angles with an RGB camera, which recognizes the relative positional relationship among the LEDs. The advantage of this approach is that the calibration is quite simple but robust, even if the coiled strips are misaligned or overlap each other. We demonstrated a proof-of-concept prototype using strips with a 5-mm width and containing LEDs mounted at 2-mm intervals. This paper discusses various example applications of the proposed system.","PeriodicalId":344160,"journal":{"name":"SIGGRAPH Asia 2020 Emerging Technologies","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131211894","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, the quality of texture reproduction is not high because these displays use high-speed projectors with low bit depth and low resolution. In this study, to address this limitation of swept volumetric displays while retaining their advantages, a new swept volumetric three-dimensional (3D) display is designed using physical materials as screens. Physical materials are directly used to reproduce textures on a displayed 3D surface. Further, our system can achieve hidden-surface removal based on real-time viewpoint tracking.","PeriodicalId":344160,"journal":{"name":"SIGGRAPH Asia 2020 Emerging Technologies","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131438604","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 is a novel approach for creating interactive graphics where a simple program describes the interaction on a vertex. Similar in design to a geometry or fragment shader on a GPU, these programs are uploaded on initialisation and do not require input from any external micro-controller while running. The interaction shader takes input from a light sensor and updates the vertex and fragment shader, an operation that can be parallelised. Once loaded onto our prototype LGPU the pipeline can create laser graphics that react within 4 ms of interaction and can run without input from a computer. The pipeline achieves this low latency by having the interaction shader communicate with the geometry and vertex shaders that are also running on the LGPU. This enables the creation of low latency displays such as car counters, musical instrument interfaces, and non-touch projected widgets or buttons. From our testing we were able to achieve a reaction time of 4 ms and from a range of up to 15 m.","PeriodicalId":344160,"journal":{"name":"SIGGRAPH Asia 2020 Emerging Technologies","volume":"79 1-3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126991371","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}

Additionally, our pixel-parallel calculation method allows a distributed system configuration so that the number of projectors can be increased by networked connections for high scalability.

However, conventional methods ignore skin deformation and have a high latency from motion to projection, which degrades the user experience. In this paper, we propose a projection mapping system that can solve such problems. First, we newly combine a state-of-the-art parametric deformable surface model with an efficient regression-based accuracy compensation method of skin deformation. The compensation method modifies the texture coordinate to achieve high-speed and highly accurate image generation for projection using joint-tracking results. Second, we develop a high-speed system that reduces latency from motion to projection within 10 ms. Compared to the conventional methods, this system provides more realistic experiences.","PeriodicalId":344160,"journal":{"name":"SIGGRAPH Asia 2020 Emerging Technologies","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132416314","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}
