Most VR applications include a visual rendering part. However, efficient and relevant visual interfacing of a human user (who can be a designer, the final user of a future product, a trainee or the subject of an experiment) raises issues about visual interfaces and depth perception in computer generated images. In this survey we review the issues raised by the visual part of VR applications. We particularly focus on the commonly used stereoscopic vision by studying its constraints and show how an efficient stereoscopic application should be designed.","PeriodicalId":403219,"journal":{"name":"2013 26th Conference on Graphics, Patterns and Images Tutorials","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115707723","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}

Eye tracking is the process of monitoring eye movements in order to determine the point of gaze or to analyze motion patterns of an eye relative to the head or the environment. This process provides essential information to tasks such as face detection, usability testing, biometric identification, human behavior studies and human-computer interaction, among others. The term textit{remote} is used whenever the eye tracker components do not have any physical contact with the user's body. In general, highly accurate commercial eye trackers are expensive. However, nowadays it is possible to develop low-cost remote eye tracking systems with off-the-shelf hardware components. By this perspective, an overview of eye tracking technologies and applications is given in this paper, and the state-of-the-art work in the field is discussed as well. Moreover, hardware components and underlying computer vision processes are also presented in this paper.","PeriodicalId":403219,"journal":{"name":"2013 26th Conference on Graphics, Patterns and Images Tutorials","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133828095","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}

Torres","doi":"10.1109/SIBGRAPI-T.2013.11","DOIUrl":"https://doi.org/10.1109/SIBGRAPI-T.2013.11","url":null,"abstract":"Every year, new sensor technologies are being implemented to improve the acquisition of high-resolution remote sensing images (RSIs). With the large amount of data provided by these sensors, novel computational approaches are constantly required to support the decision-making process based on RSI analysis. A typical problem is the recognition of target regions for land-cover mapping. In this context, the main problems are: (1) classification methods are dependent on the segmentation quality; and (2) the selection of representative samples for training is a costly process. The samples indicated by the user are not always enough to define the best segmentation scale. Furthermore, the indication of samples can be expensive, since it often requires to visit studied places in loco. The segmentation-dependence problem has been addressed in the literature by using multiscale analysis. The training sample selection problem is, in turn, addressed mainly by employing user interaction techniques which are usually combined with pixel-based classification approaches. This work aims to introduce problems, challenges, and some state-of-the-art approaches for multiscale classification of remote sensing image. The main covered topics are arranged into four sessions: research challenges, segmentation, feature extraction, and classification.","PeriodicalId":403219,"journal":{"name":"2013 26th Conference on Graphics, Patterns and Images Tutorials","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125550084","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}
