IMRCE is a lightweight, flexible, and robust Unity toolkit that allows designers and researchers to rapidly prototype mixed reality-mixed presence (MR-MP) environments that connect physical spaces, virtual spaces, and devices. IMRCE helps collaborators maintain group awareness of the shared collaborative environment by providing visual cues such as position indicators and virtual hands. At the same time IMRCE provides flexibility in how physical and virtual spaces are mapped, allowing work environments to be optimised for each collaborator while maintaining a sense of integration. The main contribution of the toolkit is its encapsulation of these features, allowing rapid development of MR-MP systems. We demonstrate IMRCE's features by linking a physical environment with tabletop and wall displays to a virtual replica augmented with support for direct 3D manipulation of shared work objects. We also conducted a comparative evaluation of IMRCE against a standard set of Unity libraries with complementary features with 10 developers, and found significant reductions in time taken, total LOC, errors, and requests for assistance.","PeriodicalId":166611,"journal":{"name":"Proceedings of the Symposium on Spatial User Interaction","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123197968","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}

Like in other sports, proper training leads to a faster increase of skill and lessens the risk of injuries. We chose a set of exercises from slackline literature and implemented an interactive trainer which guides the user through the exercises giving feedback if the exercises were executed correctly. Additionally, a post-analysis provides the trainee with more detailed feedback about her performance. The results from a study comparing the interactive slackline training system to a classic approach using a personal trainer indicate the interactive slackline training system can be used as an enjoyable and effective alternative to classic training methods (see [1] for more details). The contribution of the present demo is to showcase how whole body gestures can be used in interactive sports training systems. The design and implementation of the system informs many potential applications ranging from rehabilitation to fitness gyms and home use.","PeriodicalId":166611,"journal":{"name":"Proceedings of the Symposium on Spatial User Interaction","volume":"392 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114371367","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}

These challenges include higher demands on spatial cognition and motor skills, as well as the potential for mistakes caused by depth perception errors. We present Multiplanes, a VR drawing system that supports both the flexibility of freehand drawing and the ability to draw accurate shapes in 3D by affording both planar and beautified drawing. The system was designed to address the above-mentioned challenges. Multiplanes generates snapping planes and beautification trigger points based on previous and current strokes and the current controller pose. Based on geometrical relationships to previous strokes, beautification trigger points serve to guide the user to reach specific positions in space. The system also beautifies user's strokes based on the most probable intended shape while the user is drawing them. With Multiplanes, in contrast to other systems, users do not need to manually activate such guides, allowing them to focus on the creative process.","PeriodicalId":166611,"journal":{"name":"Proceedings of the Symposium on Spatial User Interaction","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123862108","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}

In this way, the viewer enjoys an immersive movie experience. However, due to the free choice of field-of-view, it is possible to miss details which are important for the story. On the other hand, the additional space component gives the filmmakers new opportunities to construct stories. To support filmmakers and viewers, we introduce the concept of a 'spaceline' (named in analogy to the traditional 'timeline') which connects movie sequences via interactive regions. We developed a spaceline editor that allows researchers and filmmakers to define such regions as well as indicators for visualising regions inside and outside the current field-of-view. *","PeriodicalId":166611,"journal":{"name":"Proceedings of the Symposium on Spatial User Interaction","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128008117","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 it takes advantage of situatedness compared to traditional text-based and visual programming tools, it does not allow programmers to inspect what the robot detects in the workspace, nor to understand any programming or execution errors that may arise. In this work we propose to use a projector mounted on the robot to provide such functionality. This allows us to provide an interactive situated tangible programming experience, taking advantage of situatedness, both in user input and system output, to reference parts of the robot workspace. We describe an implementation and evaluation of this approach, highlighting its differences from traditional robot programming.","PeriodicalId":166611,"journal":{"name":"Proceedings of the Symposium on Spatial User Interaction","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115495410","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, attaching a device to fingertips has issues such as difficulty in attaching and detaching and hindering free movement of fingers. To address these issues, many methods have been proposed to incorporate a haptic presentation mechanism in an HMD, but only for presenting passive tactile information of the face or whole body. To present the tactile sensation of the fingertips in a configuration that can be incorporated in an HMD, we developed a skin-suction mechanism called Haptopus to simulate the pressure applied to multiple fingers. Haptopus can express the sense of fingers touching virtual objects by presenting corresponding suction pressure around the eyes.","PeriodicalId":166611,"journal":{"name":"Proceedings of the Symposium on Spatial User Interaction","volume":"8 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":"121792689","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}
