In initial observations, we found ubiquitous use of audio-assistance technologies by VIPs for interacting with computing devices, such as Android TalkBack. However, we also saw that devices without screens frequently lack accessibility features. Our solution allows a VIP to obtain audio assistance in the presence of an arbitrary physical interface or object through a chest-mounted device. On-board are camera sensors that point towards the user's personal front-facing grasping region. Upon detecting certain gestures such as picking up an object, the device provides helpful contextual audio information to the user. Textual interfaces can be read aloud by sliding a finger over the surface of the object, allowing the user to hear a document or receive audio guidance for non-assistively-enabled electronic devices. The user may provide questions verbally in order to refine their audio assistance, or to ask broad questions about their environment. Our motivation is to provide sensemaking faculties that creatively approximate those of non-VIPs in tasks that make VIPs ineligible for common employment opportunities.","PeriodicalId":185819,"journal":{"name":"Proceedings of the 2016 Symposium on Spatial User Interaction","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125328175","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 the same way, some research has shown novel advances in wearable devices to provide vibrotactile feedback which can be combined with low-cost technology for hand tracking and gestures recognition. The combination of these technologies can be used to investigate interesting psychological illusions. For instance, body-transfer illusions, such as the rubber-hand illusion or elongated-arm illusion, have shown that it is possible to give a person the persistent illusion of body transfer after only brief phases of synchronized visual-haptic stimulation. The motivation of this paper is to induce such perceptual illusions by combining VR, vibrotactile and tracking technologies, offering an interesting way to create new spatial interaction experiences centered on the senses of sight and touch. We present a technology framework that includes a pair of self-made gloves featuring vibrotactile feedback that can be synchronized with audio-visual stimulation in order to reproduce body-transfer illusions in VR. We present in detail the implementation of the framework and show that the proposed technology setup is able to induce the elongated-arm illusion providing automatic tactile stimuli, instead of the traditional approach based on manually synchronized stimulation.","PeriodicalId":185819,"journal":{"name":"Proceedings of the 2016 Symposium on Spatial User Interaction","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121088527","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 challenge is even harder to solve since perception and action in immersive virtual environments differ significantly from the real world, causing natural user interfaces to elicit a dissociation of perceptual and motor space as well as levels of discomfort and fatigue unknown in the real world. In this paper, we present and evaluate the novel method to leverage joint-centered kinespheres for interactive spatial applications. We introduce kinespheres within arm's reach that envelope the reachable space for each joint such as shoulder, elbow or wrist, thus defining 3D interactive volumes with the boundaries given by 2D manifolds. We present a Fitts' Law experiment in which we evaluated the spatial touch performance on the inside and on the boundary of the main joint-centered kinespheres. Moreover, we present a confirmatory experiment in which we compared joint-centered interaction with traditional spatial head-centered menus. Finally, we discuss the advantages and limitations of placing interactive graphical elements relative to joint positions and, in particular, on the boundaries of kinespheres.","PeriodicalId":185819,"journal":{"name":"Proceedings of the 2016 Symposium on Spatial User Interaction","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123773860","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 large virtual workspace, the limited available field of view (FoV) may cause objects to be located outside of the available viewing area, requiring users to first locate an item using head motion before making a selection. However, FoV varies widely across different devices, with an unknown impact on interface usability. We present a user study to test two-step selection models previously proposed for \"peephole pointing\" in large virtual workspaces on mobile devices. Using a CAVE environment to simulate the FoV restriction of stereoscopic HWDs, we compare two different input methods, direct pointing, and raycasting in a selection task with varying FoV width. We find a very strong fit in this context, comparable to the prediction accuracy in the original studies, and much more accurate than the traditional Fitts' law model. We detect an advantage of direct pointing over raycasting, particularly with small targets. Moreover, we find that this advantage of direct pointing diminishes with decreasing FoV.","PeriodicalId":185819,"journal":{"name":"Proceedings of the 2016 Symposium on Spatial User Interaction","volume":"444 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125765296","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}
