The handheld display acts as a window into virtual reality, providing users with a perspective view of 3D data. T(ether) tracks users' heads, hands, fingers and pinching, in addition to a handheld touch screen, to enable rich interaction with the virtual scene. We introduce gestural interaction techniques that exploit proprioception to adapt the UI based on the hand's position above, behind or on the surface of the display. These spatial interactions use a tangible frame of reference to help users manipulate and animate the model in addition to controlling environment properties. We report on initial user observations from an experiment for 3D modeling, which indicate T(ether)'s potential for embodied viewport control and 3D modeling interactions.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128656343","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 transition has been addressed many times by science fic- tion literature and cinematographic works, which often show dystopic visions in which humans live their lives in a virtual reality (VR)-based setup, while they are immersed into a vir- tual or remote location by means of avatars or surrogates. In order to gain a better understanding of how living in such a virtual environment (VE) would impact human beings, we conducted a self-experiment in which we exposed a single participant in an immersive VR setup for 24 hours (divided into repeated sessions of two hours VR exposure followed by ten minutes breaks), which is to our knowledge the longest documented use of an immersive VEs so far. We measured different metrics to analyze how human perception, behav- ior, cognition, and motor system change over time in a fully isolated virtual world.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127127728","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}

It enables a remote expert to observe a video feed of the local worker's environment and directly specify object movements via a touch display. Visual feedback for the gestures is displayed directly in the local worker's physical environment with Spatial Augmented Reality and observed by the remote expert through the video feed. A virtual representation of the physical environment is captured with a Kinect that facilitates the context-based interactions. We evaluate two methods of remote worker interaction, object-based and sketch-based, and also investigate the impact of two camera positions, top and side, for task performance. Our results indicate translation and aggregate tasks could be more accurately performed via the object based technique when the top-down camera feed was used. While, in the case of the side on camera view, sketching was faster and rotations were more accurate. We also found that for object-based interactions the top view was better on all four of our measured criteria, while for sketching no significant difference was found between camera views.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129690980","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 common method to observe and understand how users express gestures is to use elicitation studies. However, these studies require time-consuming analysis of user data to identify gesture patterns. Also, the analysis by humans cannot describe gestures in as detail as in data-based representations of motion features. In this paper, we present GestureAnalyzer, a system that supports exploratory analysis of gesture patterns by applying interactive clustering and visualization techniques to motion tracking data. GestureAnalyzer enables rapid categorization of similar gestures, and visual investigation of various geometric and kinematic properties of user gestures. We describe the system components, and then demonstrate its utility through a case study on mid-air hand gestures obtained from elicitation studies.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127168148","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 a Fitts' law pointing experiment, we compared the effects of texturing, highlighting targets upon being touched, and the presence of support cylinders intended to eliminate floating targets. Results of the study indicate that texturing and support cylinders did not significantly influence performance. Enabling target highlighting increased movement speed, while decreasing error rate. Pointing throughput was unaffected by this speed-accuracy tradeoff. Highlighting also eliminated significant differences between selection coordinate depth deviation and the deviation in the two orthogonal axes.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129662758","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 present the iterative design and evaluation of HOBS -- a Head-Orientation Based Selection technique for interacting with these devices at a distance. We augment a commercial wearable device, Google Glass, with an infrared (IR) emitter to select targets equipped with IR receivers. Our first design shows that a naive IR implementation can outperform list selection, but has poor performance when refinement between multiple targets is needed. A second design uses IR intensity measurement at targets to improve refinement. To address the lack of natural mapping of on-screen target lists to spatial target location, our third design infers a spatial data structure of the targets enabling a natural head-motion based disambiguation. Finally, we demonstrate a universal remote control application using HOBS and report qualitative user impressions.","PeriodicalId":274675,"journal":{"name":"Proceedings of the 2nd ACM symposium on Spatial user interaction","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131166963","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}
