Recently, it was demonstrated that even pupil dilation is subject to controlled interference. To address effects of training on the ability to exercise control on pupil dilation, the current study examines repeated exercise over seven successive days. Participants utilize self-induced changes in arousal to increase pupil diameter, real-time feedback was applied to evaluate and improve individual performance. We observe inter-individual differences with regard to responsiveness of the pupillary response: six of eight participants considerably increase pupil diameter already during the first session, two exhibit only slight changes, and all showed rather stable performance throughout training. There was a trend towards stronger peak amplitudes that tend to occur increasingly early across time. Hence, higher cognitive control on pupil dilations can be practiced by most users and may therefore provide an appropriate input mechanism in human-computer interaction.","PeriodicalId":237808,"journal":{"name":"Proceedings of the 2018 ACM Symposium on Eye Tracking Research & Applications","volume":"PE-1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126755736","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}

Existing methods, however, either ignore or require complex hardware setups to deal with refraction effects occurring at the corneal interfaces. In this work we provide a detailed analysis of the effects of refraction in glint-free gaze estimation using a single near-eye camera, based on the method presented by [Świrski and Dodgson 2013]. We demonstrate systematic deviations in inferred eyeball positions and gaze directions with respect to synthetic ground-truth data and show that ignoring corneal refraction can result in angular errors of several degrees. Furthermore, we quantify gaze direction dependent errors in pupil radius estimates. We propose a novel approach to account for corneal refraction in 3D eye model fitting and by analyzing synthetic and real images show that our new method successfully captures refraction effects and helps to overcome the shortcomings of the state of the art approach.","PeriodicalId":237808,"journal":{"name":"Proceedings of the 2018 ACM Symposium on Eye Tracking Research & Applications","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133821972","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}

First, the individuals' gaze patterns, represented by the unique fixations on each area of interest (AOI) and the total fixation duration per AOI, are calculated. Second, the gaze-based entropy of the individual is calculated. To investigate whether the proposed metric is a credible predictor of the password strength, we conducted two feasibility studies. Results revealed a strong positive correlation between the strength of the created passwords and the gaze-based entropy. Hence, we argue that the proposed gaze-based metric allows for unobtrusive prediction of the strength of the password a user is going to create and enables intervention to the password composition for helping users create stronger passwords.","PeriodicalId":237808,"journal":{"name":"Proceedings of the 2018 ACM Symposium on Eye Tracking Research & Applications","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132989370","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 demonstrate a multimodal browsing approach combining eye gaze and voice inputs for optimized interaction, and to suffice user preferences with unimodal benefits.

Current approaches to eye tracking are meant for fixed stimuli and struggle to capture context during these activities. iTrace overcomes these limitations allowing developers to work in realistic settings during an eye tracking study.

Three-dimensional (3D) gaze estimates would be extremely useful when humans are mobile and interacting with the real 3D environment. We describe a system for estimating the 3D locations of gaze using a mobile eye tracker. The system integrates estimates of the user's gaze vector from a mobile eye tracker, estimates of the eye tracker pose from a visual-inertial simultaneous localization and mapping (SLAM) algorithm, a 3D point cloud map of the environment from a RGB-D sensor. Experimental results indicate that our system produces accurate estimates of 3D gaze over a much larger range than remote eye trackers. Our system will enable applications, such as the analysis of 3D human attention and more anticipative human robot interfaces.","PeriodicalId":237808,"journal":{"name":"Proceedings of the 2018 ACM Symposium on Eye Tracking Research & Applications","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127245955","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}

Our Gaze-Contingent Intention Decoding Engine uses eye-movement data and gaze-point position to indicate the hidden intention. We detect the object of interest using deep convolution neural networks and estimate its position in a physical space using 3D gaze vectors. Then we trigger the possible actions from an action grammar database to perform an assistive movement of the robotic arm, improving action performance in physically disabled people.

The ability to sight-read a score is typically described as one of the most challenging aims for beginners and finding ways of scaffolding their learning is, therefore, an important task for researchers in music education. The purpose of this study is to provide a deeper understanding of how an application of eye tracking technology can be utilized to improve choir singers' sight-reading ability. Collected data of novices' sight-reading patterns during choral rehearsal have helped identify problems that singers are facing. Analyzing corresponding patterns in sight-reading performed by expert singers may provide valuable information about helpful strategies developed with increasing experience. This project is expected to generate an approximate model, similar to the experts' eye movement path. The model will then be implemented in a training method for unskilled choral singers. Finally, as a summative result, we plan to evaluate how the training affects novices' competency in sight-reading and comprehension of the score.","PeriodicalId":237808,"journal":{"name":"Proceedings of the 2018 ACM Symposium on Eye Tracking Research & Applications","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121761566","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 paper explores how audience and presenter coordinate visual and verbal information, and how consistent their gaze behavior is, to understand if their gaze behavior can be used for inferring and communicating attention in remote presentations. In a lab study, participants were asked first to view a short video presentation, and next, to rehearse and present to a remote viewer using the slides from the video presentation. We found that presenters coordinate their speech and gaze at visual regions of the slides in a timely manner (in 72% of all events analyzed), whereas audience only looked at what the presenter talked about in 53% of all events. Rehearsing aloud and presenting resulted in similar scanpaths. To further explore if it possible to infer if what a presenter is looking at is also talked about, we successfully trained models to detect an attention match between gaze and speech. These findings suggest that using the presenter's gaze has the potential to reliably communicate the presenter's focus on essential parts of the visual presentation material to help the audience better follow the presenter.","PeriodicalId":237808,"journal":{"name":"Proceedings of the 2018 ACM Symposium on Eye Tracking Research & Applications","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114367748","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}
