Developing good spatial understanding is highly dependent on how the viewer's attention is deployed to specific locations in a scene. Bailey et al. [2009] showed that it is possible to influence exactly where attention is allocated using a technique called Subtle Gaze Direction (SGD). The SGD approach combines eye tracking with subtle image-space modulations to guide viewer gaze about a scene. The modulations are presented to peripheral regions of the field of view, in order to attract the viewer's attention, but are terminated before the viewer can scrutinize them with their high acuity foveal vision. It was observed that subjects who were guided using SGD performed significantly better in recollecting the count and location of target objects, however no significant performance improvement was observed in identifying the shape of the target objects [Bailey et al. 2012]. Also, in previous studies involving SGD, the target locations were manually chosen by researchers. This paper addresses these two limitations. We present a novel technique for automatically selecting target regions using visual saliency and key features in the image. The shape recollection issue is solved by modulating a rough outline of the target object obtained using an edge map composed from a pyramid of low spatial frequency maps of the original image. Results from a user study show that the influence of this approach significantly improved accuracy of target count recollection, location recollection, as well as shape recollection without any manual intervention. Furthermore our technique correctly predicted 81% of the target regions without any prior knowledge of the recollection task being assigned to the viewer. This work has implications for a wide range of applications including spatial learning in virtual environments as well as image search applications, virtual training and perceptually based rendering.","PeriodicalId":283323,"journal":{"name":"Proceedings of the ACM SIGGRAPH Symposium on Applied Perception","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126900950","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}

For over 200 years, people have been writing about this experience, for example stating that vastness is important to the experience of awe [Mikulak 2015]. Yet vastness has received little attention in empirical research. Specifically, it is unknown which aspects of the visual stimulus contribute to perceived vastness. This may be due to the inherent difficulties in presenting a variety of vast stimuli while varying only specific visual cues. Using virtual reality addresses these difficulties, as this technology provides precise control over the presented visual stimuli. Here we investigate whether the feeling of vastness can be evoked using virtual reality and explore potential objective measures to assess vastness. We used three different measures during this experiment: 1) An avatar height adjustment task where participants had to adjust an avatar to be equivalent to their own height as viewed from a distance, 2) a distance estimation task and 3) a subjective vastness rating task. These tasks were performed in four environments: a plain (used in all subsequent environments for the ground and sky surfaces), a forest, a mountain and the mountain and forest environments combined. Our results indicate that the feeling of vastness can indeed be experienced to various degrees in virtual environments, demonstrating the potential of VR as a tool for exploring the perception of vastness. Yet the results combined suggest that the percept of vastness is a rather complex construct.","PeriodicalId":283323,"journal":{"name":"Proceedings of the ACM SIGGRAPH Symposium on Applied Perception","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116751040","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}
