The system consists of glass-type device shifting its center of gravity in response to the user’s motion which allows drinking a beverage with a virtual perception of weight through drinking motion. We thought It’s possible to intervene in the user’s perception of flavor by displaying virtual weight perception, and so conducted experiments on weight perception and demonstrations as a user study. This paper describes the system design, the result of experiments, and comments obtained through a user study.","PeriodicalId":286424,"journal":{"name":"ACM SIGGRAPH 2021 Emerging Technologies","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114483952","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}

What is novel in our device is that it quickly tucks away when the user interacts with real-world objects. Its design allows it to fold back on top of the user's nail when not in use, keeping the user's fingerpad free to, for instance, manipulate handheld tools and other objects while in MR. To achieve this, we engineered a wireless and self-contained haptic device, which measures 24×24×41 mm and weighs 9.5 g. Furthermore, our foldable end-effector also features a linear resonant actuator, allowing it to render not only touch contacts (i.e., pressure) but also textures (i.e., vibrations). We demonstrate how our device renders contacts with MR surfaces, buttons, low- and high-frequency textures.","PeriodicalId":286424,"journal":{"name":"ACM SIGGRAPH 2021 Emerging Technologies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128032104","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}

Being a projected image, the mallet can freely “metamorphose” into different shapes, which expands the game design beyond the original air hockey. We discuss possible scenarios with a resizable mallet, with mallet shapes defined by drawing, and with a mallet whose collision conditions can be modified. A key challenge in implementation is to minimize the latency because the direct manipulation nature of the mallet positioning imposes a higher demand on latency than the puck positioning. By using a high-speed camera and a high-speed projector running at 420 fps, a satisfactorily quick tracking became possible such that we feel a projected mallet head to be an integral part of a mallet held by hand.","PeriodicalId":286424,"journal":{"name":"ACM SIGGRAPH 2021 Emerging Technologies","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132222896","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 Ubimouse, touch-panels, restaurant ordering systems, ATM systems, and etc., which are commonly used by various people in public, can be contact-less devices. These touch-less devices, especially under the harsh conditions of COVID-19, are desired to prevent infections mediated by touch devices. Also, these devices cannot be used while wearing gloves due to their touch sensing fault. Thus, in fields using gloves, there is a demand for non-contact device operation. To satisfy these demands, we have developed “UbiMouse”. This is an AI software that allows you to operate the device by moving your fingers toward the device. In the AIs in UbiMouse, a convolution model and a regression model are used to identify fingers’ features from camera footage and to estimates the position of a detected finger, respectively. We demonstrate an operation of UbiMouse without contact. Along with this operation in the air, a mouse cursor is guided to the specified location with high accuracy.","PeriodicalId":286424,"journal":{"name":"ACM SIGGRAPH 2021 Emerging Technologies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115353711","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}

When the user's finger wearing our voice-coil contacts any of the interactive patches it detects its magnetic signature via magnetometer and vibrates the patch, adding haptic feedback to otherwise input-only interactions. To allow these passive patches to vibrate, we make them from silicone with regions doped with polarized neodymium powder, resulting in soft and stretchable magnets. This stretchable form-factor allows them to be wrapped to the user's body or everyday objects of various shapes. We demonstrate how these add haptic output to many situations, such as adding haptic buttons to the walls of one's home.","PeriodicalId":286424,"journal":{"name":"ACM SIGGRAPH 2021 Emerging Technologies","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127318317","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}

While computational assistance can improve performance, naive intervention independent of the context also compromises the user’s sense of agency. We propose a context-aware assistance method that retrieves both user performance and sense of agency, and we demonstrate the method using air hockey (a two-dimensional physical game) as a testbed. Our system includes a 2D plotter-like machine that controls the striker on half of the table surface, and a web application interface that enables manipulation of the striker from a remote location. Using our system, a remote player can play against a physical opponent from anywhere through a web browser. We designed the striker control assistance based on the context by computationally predicting the puck’s trajectory using a real-time captured video image. With this assistance, the remote player exhibits an improved performance without compromising their sense of agency, and both players can experience the excitement of the game.","PeriodicalId":286424,"journal":{"name":"ACM SIGGRAPH 2021 Emerging Technologies","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128232338","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}
