PURPOSE/THESIS: The aim of the research paper is to outline web usability evaluation based on eye tracking and to determine the usability of the website of the National Museum - Pałace of the Grand Dukes of Lithuania from the user perspective in the process of searching for the most required Information. APPROACH/METHODS: A literature analysis was used to get acquainted with usability evaluation methods and the historical review of visual attention studies, Questionnaire based interviews with visitors of the museums were used to collect Information about people Information needs and searching patterns on museum websites. In order to evaluate the website of the National Museum - Palace of the Grand Dukes of Lithuania the researchers used eye tracking equipment. RESULTS AND CONCLUSIONS: The eye tracking have recently gained attention in different research areas, however issues of museum website design and usability research using eye tracking techniąues and methods have not been widely discussed in scientific literature so far. The research on the Information needs of the visitors of Lithuanian museum websites revealed the most reąuired Information: opening hours, museum location, entrance ticket price and Information about exhibitions. The results confirmed the assumption that people used museum websites as a primary tool to prepare for a visit at the physical museum. The eye tracking analysis of the website of the National Museum - Palace of the Grand Dukes of Lithuania revealed the typical mistakes and errors made in Information placement. When the Information most needed by the users is placed in different parts and levels of the website, the visitors have to spend more time and effort to find the Information and to prepare for a visit at the museum. ORIGINALITY/VALUE: Issues of the museum websites design are not widely discussed in worldwide scientific literature. There are no data about eye tracker based research on museum websites done in Lithuania before. The analysis results may contribute to new knowledge about designing successful interfaces for museum websites. Moreover, the results could be used in a broader field to improve the interfaces and Information representation for websites in general.

Abstract Temperamental behavioral inhibition (BI) is a robust endophenotype for anxiety characterized by increased sensitivity to novelty. Controlling parenting can reinforce children's wariness by rewarding signs of distress. Fine-grained, dynamic measures are needed to better understand both how children perceive their parent's behaviors and the mechanisms supporting evident relations between parenting and socioemotional functioning. The current study examined dyadic attractor patterns (average mean durations) with state space grids, using children's attention patterns (captured via mobile eye tracking) and parental behavior (positive reinforcement, teaching, directives, intrusion), as functions of child BI and parent anxiety. Forty 5- to 7-year-old children and their primary caregivers completed a set of challenging puzzles, during which the child wore a head-mounted eye tracker. Child BI was positively correlated with proportion of parent's time spent teaching. Child age was negatively related, and parent anxiety level was positively related, to parent-focused/controlling parenting attractor strength. There was a significant interaction between parent anxiety level and child age predicting parent-focused/controlling parenting attractor strength. This study is a first step to examining the co-occurrence of parenting behavior and child attention in the context of child BI and parental anxiety levels.

Currently an increasing number of head mounted displays (HMD) for virtual and augmented reality (VR/AR) are equipped with integrated eye trackers. Use cases of these integrated eye trackers include rendering optimization and gaze-based user interaction. In addition, visual attention in VR and AR is interesting for applied research based on eye tracking in cognitive or educational sciences for example. While some research toolkits for VR already exist, only a few target AR scenarios. In this work, we present an open-source eye tracking toolkit for reliable gaze data acquisition in AR based on Unity 3D and the Microsoft HoloLens 2, as well as an R package for seamless data analysis. Furthermore, we evaluate the spatial accuracy and precision of the integrated eye tracker for fixation targets with different distances and angles to the user (n=21). On average, we found that gaze estimates are reported with an angular accuracy of 0.83 degrees and a precision of 0.27 degrees while the user is resting, which is on par with state-of-the-art mobile eye trackers.

The Given

AbstractThis paper presents results of the effect of different translation modalities on users when working with the Microsoft Word user interface. An experimental study was set up with 84 Japanese, German, Spanish, and English native speakers working with Microsoft Word in three modalities: the published translated version, a machine translated (MT) version (with unedited MT strings incorporated into the MS Word interface) and the published English version. An eye-tracker measured the cognitive load and usability according to the ISO/TR 16982 guidelines: i.e., effectiveness, efficiency, and satisfaction followed by retrospective think-aloud protocol. The results show that the users’ effectiveness (number of tasks completed) does not significantly differ due to the translation modality. However, their efficiency (time for task completion) and self-reported satisfaction are significantly higher when working with the released product as opposed to the unedited MT version, especially when participants are less experienced. The eye-tracking results show that users experience a higher cognitive load when working with MT and with the human-translated versions as opposed to the English original. The results suggest that language and translation modality play a significant role in the usability of software products whether users complete the given tasks or not and even if they are unaware that MT was used to translate the interface.

Traditional Approaches

Optokinetic nystagmus (OKN) is an involuntary eye movement induced by motion of a large proportion of the visual field. It consists of a “slow phase (SP)” with eye movements in the same direction as the movement of the pattern and a “fast phase (FP)” with saccadic eye movements in the opposite direction. Study of OKN can reveal valuable information in ophthalmology, neurology and psychology. However, the current commercially available high-resolution and research-grade eye tracker is usually expensive. Methods & Results: We developed a novel fast and effective system combined with a low-cost eye tracking device to accurately quantitatively measure OKN eye movement. Conclusions: The experimental results indicate that the proposed method achieves fast and promising results in comparisons with several traditional approaches.

Artistic Images

In this paper, authors present a novel architecture for controlling an industrial robot via an eye tracking interface for artistic purposes. Humans and robots interact thanks to an acquisition system based on an eye tracker device that allows the user to control the motion of a robotic manipulator with his gaze. The feasibility of the robotic system is evaluated with experimental tests in which the robot is teleoperated to draw artistic images. The tool can be used by artists to investigate novel forms of art and by amputees or people with movement disorders or muscular paralysis, as an assistive technology for artistic drawing and painting, since, in these cases, eye motion is usually preserved.

Introduction and Objectives: Surgical treatment for trigonocephaly aims to eliminate a stigmatizing deformity, yet the severity that captures unwanted attention is unknown. Surgeons intervene at different points of severity, eliciting controversy. This study used eye tracking to investigate when deformity is perceived. Material and Methods: Three-dimensional photogrammetric images of a normal child and a child with trigonocephaly were mathematically deformed, in 10% increments, to create a spectrum of 11 images. These images were shown to participants using an eye tracker. Participants’ gaze patterns were analyzed, and participants were asked if each image looked “normal” or “abnormal.” Results: Sixty-six graduate students were recruited. Average dwell time toward pathologic areas of interest (AOIs) increased proportionally, from 0.77 ± 0.33 seconds at 0% deformity to 1.08 ± 0.75 seconds at 100% deformity ( P < .0001). A majority of participants did not agree an image looked “abnormal” until 90% deformity from any angle. Conclusion: Eye tracking can be used as a proxy for attention threshold toward orbitofrontal deformity. The amount of attention toward orbitofrontal AOIs increased proportionally with severity. Participants did not generally agree there was “abnormality” until deformity was severe. This study supports the assertion that surgical intervention may be best reserved for more severe deformity.

Los patrones normales de movimiento ocular de lectura tienen 3 componentes principales: movimientos sacádicos que mueven los ojos de una palabra a otra, movimientos sacádicos que devuelven los ojos al comienzo de la siguiente línea, y pausas de fijación entre cada movimiento sacádico para el procesamiento de la información. Las propuestas de patrones oculares en imágenes estáticas sirven para corroborar el comportamiento de orden de visualización o lectura. En este trabajo se ha verificado, mediante biometría de neuromarketing, el patrón de respuesta a un estímulo estático, basado en un texto con cambios de tamaño de letra y ubicación, el cual prevé el patrón de fijación de los usuarios. La biometría empleada fue eye tracking, obteniendo datos de visualización, mapas de calor y mapas de fijación que verifican el orden seguido por la mayoría de los usuarios. Con esta técnica pasiva se pretendía obtener los patrones mentales de lectura, estableciendo las áreas de interés previamente, a través de la aplicación informática del eye tracker. El resultado confirma que el patrón de lectura no se corresponde a las indicaciones del texto en la imagen estática, descartando la propuesta del estímulo y descubriendo que el ojo lee en un determinado orden, según la cultura de aprendizaje.
