These challenges call for the development of new methods that are robust to such influences. In this paper we investigate the problem of gaze estimation, more specifically how to discriminate different gaze directions from eye images. In a 17 participant user study we record eye images for 13 different gaze directions from a standard webcam. We extract a total of 50 features from these images that encode information on color, intensity and orientations. Using mRMR feature selection and a k-nearest neighbor (kNN) classifier we show that we can estimate these gaze directions with a mean recognition performance of 86%.","PeriodicalId":405392,"journal":{"name":"PETMEI '11","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125187237","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}

Through analyzing the pattern of eye movement, we can make it clear how human accomplish everyday life with eyes. As human lives in the communities which are artificial environments, various man-made signs, objects and surrounding people have influence on human, particularly on eye movement pattern. To fully understand the eye movement pattern, we have to consider the human factors. This paper focuses on clarifying eye movement pattern during riding motorcycle on the mountain. We use a mobile eye mark tracking system to record the eye motion and the front view. By referring the recorded movie, eye mark analysis and fixation point analysis verify the influence from human factor. In addition, we provide suggestions to promote safe riding.","PeriodicalId":405392,"journal":{"name":"PETMEI '11","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126913893","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 allows initiating various events or commands when a test person is wearing the head unit and the gaze is detected in an AOI. The commands can be used for interaction with different devices. Thus the tool for monitoring and analyzing gaze behavior becomes an interaction medium. With such a gaze control multi-modal interaction concepts could be realized. The projects primary aim was to give people with tetraplegia a mean of controlling devices in their home. The experimental set-up was a TV set that can be controlled by gaze.","PeriodicalId":405392,"journal":{"name":"PETMEI '11","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121592463","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}

The lack of constraints that make mobile systems such powerful tools prevent the analysis tools designed for static or tracked observers from working with freely moving observers.\u0000 Proposed solutions have included infrared markers hidden in the scene to provide reference points, Simultaneous Localization and Mapping (SLAM), and multi-view geometry techniques that build models from multiple views of a scene. These methods map fixations onto predefined or extracted 3D scene models, allowing traditional static-scene analysis tools to be used.\u0000 Another approach to analysis of mobile eyetracking data is to code fixations with semantically meaningful labels rather than mapping the fixations to fixed 3D locations. This offers two important advantages over the model-based methods; semantic mapping allows coding of dynamic scenes without the need to explicitly track objects, and it provides an inherently flexible and extensible object-based coding scheme.","PeriodicalId":405392,"journal":{"name":"PETMEI '11","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133706147","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}

An example is reported in which a mobile device user interface is analyzed in on-screen simulation using a remote eye-tracker, and with the real device using a portable eye-tracker.

Gaze information strongly reflects the human interest or their attention, and thus, a gaze-based interface is promising for future usage. In particular, if we can smoothly guide the user's visual attention toward a target without interrupting their current visual attention, the usefulness of the gaze-based interface will be highly enhanced. To realize such an interface, this paper proposes a method for editing an image, when given a region in the image, to synthesize the image in which the region is most salient. Our method first computes a saliency map of a given image and then iteratively adjusts the intensity and color until the saliency inside the region becomes the highest for the entire image. Experimental results confirm that our image editing method naturally draws the human visual attention toward our specified region.","PeriodicalId":405392,"journal":{"name":"PETMEI '11","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114899601","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}

The advent of pervasive eye tracking promises new applications, such as eye-based mental health monitoring or eye-based activity and context recognition. These applications might require further research on additional eye movement types such as smooth pursuits and the vestibulo-ocular reflex as these movements have not been studied as extensively as saccades, fixations and blinks. In this paper we report our first step towards an effective discrimination of these movements. In a user study we collect naturalistic eye movements from 19 people using the two most common measurement techniques (EOG and IR-based). We develop a set of basic signal features that we extract from the collected eye movement data and show that a feature-based approach has the potential to discriminate between saccades, smooth pursuits, and vestibulo-ocular reflex movements.","PeriodicalId":405392,"journal":{"name":"PETMEI '11","volume":"96 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125983892","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 other words, the subjects need to search for and recognize the target before the final selection in each trial. The results clarify the suitable ranges of dwell time for users to avoid wrong selections as possible as they can under different cognitive load conditions.
