In many interactions, the eyes naturally point at objects of interest while the hands skilfully manipulate in 3D space. We explore a particular combination for virtual reality, the Gaze + Pinch interaction technique. It integrates eye gaze to select targets, and indirect freehand gestures to manipulate them. This keeps the gesture use intuitive like direct physical manipulation, but the gesture's effect can be applied to any object the user looks at --- whether located near or far. In this paper, we describe novel interaction concepts and an experimental system prototype that bring together interaction technique variants, menu interfaces, and applications into one unified virtual experience. Proof-of-concept application examples were developed and informally tested, such as 3D manipulation, scene navigation, and image zooming, illustrating a range of advanced interaction capabilities on targets at any distance, without relying on extra controller devices.","PeriodicalId":402574,"journal":{"name":"Proceedings of the 5th Symposium on Spatial User Interaction","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121318465","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}

Though real walking is the most natural for medium distances, it gets physically demanding and inefficient after prolonged use, while the sudden viewpoint changes experienced with teleportation often lead to disorientation. To close the gap between travel over long and short distances, we introduce TriggerWalking, a biomechanically-inspired locomotion user interface for efficient realistic virtual walking. The idea is to map the human's embodied ability for walking to a finger-based locomotion technique. Using the triggers of common VR controllers, the user can generate near-realistic virtual bipedal steps. We analyzed head oscillations of VR users while they walked with a head-mounted display, and used the data to simulate realistic walking motions with respect to the trigger pulls. We evaluated how the simulation of walking biomechanics affects task performance and spatial cognition. We also compared the usability of TriggerWalking with joystick, teleportation, and walking in place. The results show that users can efficiently use TriggerWalking, while still benefiting from the inherent advantages of real walking.","PeriodicalId":402574,"journal":{"name":"Proceedings of the 5th Symposium on Spatial User Interaction","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115045659","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}

At the same time, a growing volume of research connects cognitive science theories with tangible/embodied interactions (TEI) and virtual reality (VR) to offer novel means to support spatial cognition. But very few VR-TEI systems are specifically designed to support spatial ability, nor are they evaluated with respect to spatial ability. In this paper, we present the background, approach, and evaluation of TASC (Tangibles for Augmenting Spatial Cognition), a VR-TEI system built to support spatial perspective taking ability. We tested 3 conditions (tangible VR, keyboard/mouse, control; n=46). Analysis of the pre/post-test change in performance on a perspective taking test revealed that only the VR-TEI group showed statistically significant improvements. The results highlight the role of tangible VR design for enhancing spatial cognition.","PeriodicalId":402574,"journal":{"name":"Proceedings of the 5th Symposium on Spatial User Interaction","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124836475","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 paper, we explore a novel approach for conversation support through augmented information bits, allowing users to see and access information right in front of their eyes. To that end, we investigate the requirements for the design of a user interface to support conversations through proactive information retrieval in an exploratory study. Based on the results, we 2) present CloudBits: A set of visualization and interaction techniques to provide mutual awareness and enhance coupling in conversations through augmented zero-query search visualization along with its prototype implementation.

In this paper, we introduce GestureDrawer, a one-handed interaction with a 3D imaginary interface. Our approach allows users to self-define an imaginary interface, acquire visuospatial memory of the position of its controls in empty space and enables them to select or manipulate those controls by moving their hand in all three dimensions. We evaluate our approach with three user studies and demonstrate that users can indeed position imaginary controls in 3D empty space and select them with an accuracy of 93% without receiving any feedback and without fixed landmarks (e.g. second hand). Further, we show that imaginary interaction is generally faster than mid-air interaction with graphical user interfaces, and that users can retrieve the position of their imaginary controls even after a proprioception disturbance. We condense our findings into several design recommendations and present automotive applications.","PeriodicalId":402574,"journal":{"name":"Proceedings of the 5th Symposium on Spatial User Interaction","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123311438","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}
