Abstract:

Interface evaluation by eye tracking-derived data is discussed in this review and synthesis paper. While analysis of eye movements during interface use is becoming more popular, there is little basis for justification of eye tracking methods. A review of traditional interface assessment methods and criteria is provided, to establish areas where eye tracking may potentially impact interface evaluations. Studies are then reviewed, that have used eye tracking-derived measures for performance assessment as interfaces are manipulated. A synthesis is then provided, suggesting that eye tracking-based analysis could have a positive impact in evaluations of consistency, resources, visual clarity, and flexibility, and should have difficulty in ascertaining interface compatibility and locus of control.

Abstract:

Recently, various user interfaces are developed. However the operation of user interface is very difficult for the physically handicapped persons who cannot move their hand. The stationary user interface we are proposing uses head tracking via a camera and a display. It is portable and can operate household appliances. It is also operated intuitively in head tracking.

Abstract:

Abstract. Natural user interface (NUI) is a successor of command line interfaces (CLI) and graphical user interfaces (GUI) so well known to computer users. A new natural approach is based on extensive human behaviors tracking, where hand tracking and gesture recognition seem to play the main roles in communication. The presented paper reviews common approaches to discussed hand features tracking and provides a very effective proposal of the contour based hand’s poses recognition method which can be straightforwardly used for a hand-based natural user interface. Its possible usage varies from medical systems interaction, through games up to impaired people communication support.

Abstract:

Surveys have shown that 75% of users get frustrated with search engines and only 21% find relevant information. Inability to find relevant results can be partially attributed to cluttered results pages and failure in constructing Boolean queries. This research used sixteen subjects to evaluate two types of search results interfaces using four tasks while measuring performance and studying their ocular behavior using a Tobii 1750 eye-tracker. The two interfaces used were list interface, commonly seen on many search engines and a tabular interface presenting information in discrete categories or elements of the result's abstract. Quantitative comparisons of two interfaces are made on performance metrics such as time and errors, process metrics such as fixation durations, number of fixations, and eye movement transitions from one element or category of the abstract. Subjective data was collected through post-task and post-test questionnaires. The results did not show any significant difference in performance between the two interfaces, however, eye movements analysis provide some insights into importance of search result's abstract elements such as title, summary, and URL of the interface while searching.

Abstract:

AbstractA front tracking method combined with the real ghost fluid method (RGFM) is proposed for simulations of fluid interfaces in two-dimensional compressible flows. In this paper the Riemann problem is constructed along the normal direction of interface and the corresponding Riemann solutions are used to track fluid interfaces. The interface boundary conditions are defined by the RGFM, and the fluid interfaces are explicitly tracked by several connected marker points. The Riemann solutions are also used directly to update the flow states on both sides of the interface in the RGFM. In order to validate the accuracy and capacity of the new method, extensive numerical tests including the bubble advection, the Sod tube, the shock-bubble interaction, the Richtmyer-Meshkov instability and the gas-water interface, are simulated by using the Euler equations. The computational results are also compared with earlier computational studies and it shows good agreements including the compressible gas-water system with large density differences.

Abstract:

Universal design is a philosophy of creating various products and the environment to adapt to the most comprehensive possible group of recipients. This article aims to compare interfaces with the principles of universal design and application interfaces that ignore such principles. After the literature review, the following research hypotheses were posed: “Higher interface contrast affects the visibility and speed of searching for individual elements of user interface” and “The arrangement of interface elements has a significant impact on navigating the website”. The research was conducted on two websites. The Empik storefront was a webservice that did not comply with universal design principles. The application that follow the regulations of universal design was created for the purpose of research. Three methods of measuring the quality of interfaces were used in the study: WAVE tool, eye-tracking tests, and subjective assessment using the LUT questionnaire (Lublin University of Technology). Eye tracking study showed that participants needed an average of 2 times less time to locate elements on a high-contrast interface and 4 times less time to locate all components placed compliant with generally accepted design standards.

Abstract:

As our computing needs change and the availability of advanced input systems begin to increase we find that we are coming to the point where current interfaces are beginning to become outdated. Touch interfaces are becoming abundant, but there is only so much that one can do with a 2D input. This project tries to show that there is a potential for IR based interface systems to replace standard mouse input in current as well as future interfaces. Our results show that both the accuracy and robustness of the IR system designed herein are equivalent to that of standard mouse input.

Abstract:

In the development of Level 4 automated driving functions, very specific, but diverse, requirements with respect to the operational design domain have to be considered. In order to accelerate this development, it is advantageous to combine dedicated state-of-the-art software components, as building blocks in modular automated driving function architectures, instead of developing special solutions from scratch. However, e.g., in local motion planning and control, the combination of components is still limited in practice, due to necessary interface alignments, which might yield sub-optimal solutions and additional development overhead. The application of generic interfaces, which manage the data transfer between the software components, has the potential to avoid these drawbacks and hence, to further boost this development approach. This publication contributes such a generic interface concept between the local path planning and path tracking systems. The crucial point is a generalization of the lateral tracking error computation, based on an introduced error classification. It substantiates the integration of an internal reference path representation into the interface, to resolve the component interdependencies. The resulting, proposed interface enables arbitrary combinations of components from a comprehensive set of state-of-the-art path planning and tracking algorithms. Two interface implementations are finally applied in an exemplary automated driving function assembly task.

Abstract:

Many interface events and problems occur during the construction phase of construction projects, such that tracking and controlling these are essential to construction management. Interface management (IM) has become the most important aspect of a sound project management strategy. IM affects project cost, scheduling, and quality both directly and indirectly in construction projects. Interface or changed events can be identified and tracked using IM, such that construction processes can be improved, while minimizing rework and reducing total project duration. Despite the many studies and discussions in academic and practical literature, systematic approaches and information platforms for managing interface events and problems during the construction are lacking. This study tracks and manages interface events using novel three-dimensional (3D) interface maps integrated into the building information modelling (BIM) approach. The BIM approach, which is utilized to retain interface information in a digital format, facilitates easy interface updating and transfer in the 3D CAD environment. The 3D-based interface maps provide users with an overview of interface events during a given construction project, such that users can track and manage interfaces virtually. The primary purpose of this study is to develop a web Construction BIM-based IM (ConBIM-IM) system for engineers to enhance interface information sharing and efficiency tracking in construction projects. The ConBIM-IM system is applied to a case study of a building project in Taiwan to verify its efficacy and demonstrate its IM effectiveness. Case study results show that the ConBIM-IM system is effective for managing interfaces using the BIM approach in construction.

Abstract:

It is crucial that the interface design of mobile apps be age-appropriate at this stage of global aging, as the new epidemic has resulted in a higher sense of isolation among older persons. In this study, four typical senior social service mobile applications were chosen to give older persons the ability to complete user login duties. The participants were 16 older adults (7 men and 9 women) aged 55 to 76. Both objective and subjective data, including task completion time, gaze length, pupil diameter changes, EEG wave amplitude changes, and subjective sensations of older persons, were gathered using a combination of eye-movement and EEG signal approaches. The program was created to investigate the effects of interface design aspects on older people’s task performance, including interface layout, interface color, information density, icon size and position, etc. The study’s findings revealed that when the user task completion time and average fixation duration were shorter, the line of sight was more equally distributed, the visual focus was closer to the login button, and the average EEG amplitude of the user changed more, the older adults performed better. The palace layout had a more positive effect on job completion among older individuals when it came to interface layout. In terms of interface color, colored (contrasting) colors should serve to highlight the interface’s essential information points while they can be removed. In terms of interface information density, a low-density level interface design can simplify and lower the cognitive load of task execution for older people. The first level of icons in the interface and their position in the visual center of the interface is the best interface design for older persons in terms of icon size and position. The results of this study have theoretical ramifications for a thorough understanding of the factors influencing older people’s task performance, practical ramifications for the design of older people-centered interfaces, and they contribute to our understanding of the characteristics of older people’s interface interaction behavior.

Abstract:

Abstract Eye-gaze tracking is an aspect of human-computer interaction still growing in popularity,. Tracking human gaze point can help control user interfaces and may help evaluate graphical user interfaces. At the same time professional eye-trackers are very expensive and thus unavailable for most of user interface researchers and small companies. The paper presents very effective, low cost, computer vision based, interactive eye-gaze tracking method. On contrary to other authors results the method achieves very high precision (about 1.5 deg horizontally and 2.5 deg vertically) at 20 fps performance, exploiting a simple HD web camera with reasonable environment restrictions. The paper describes the algorithms used in the eye-gaze tracking method and results of experimental tests, both static absolute point of interest estimation, and dynamic functional gaze controlled cursor steering.

Abstract:

As more data are recorded in digital form the importance of automatically extracting parameters of glaciological significance increases. This paper addresses the problem, with particular reference to tracking bedrock or internal reflectors in digitally recorded Radio Echo Sounding (RES) data. It has been found that the simplest solution to this problem is a “supervised” system, where operator decisions may be added interactively, either on operator command or upon loss of track. Increasing internal decision making within the program may reduce the number of operator interventions required, but is unlikely to eliminate them completely.Algorithms are presented and discussed for determining the position of the interface, for predicting the position of the interface in successive records, for determining the loss of track condition, and for re-acquiring track after loss of track.

Abstract:

Eye-tracking was used to investigate the attentional processes whereby different types of focus on form (FonF) instruction assist learners in overcoming learned attention and blocking effects in their online processing of second language input. English native speakers viewed Latin utterances combining lexical and morphological cues to temporality under control conditions and three types of explicit FonF: verb grammar instruction, verb salience with textual enhancement, and verb pretraining. Chinese native speakers were also tested on control and verb grammar conditions. All groups participated in three phases: exposure, comprehension test, and production test. Verb grammar participants viewed a short lesson on Latin tense morphology prior to exposure. Verb salience participants saw the verb inflections highlighted in bold and red during exposure. Verb pretraining participants took part in an additional introductory phase in which they were presented with solitary verb forms and were trained on their English translations. Instructed participants showed greater sensitivity to morphological cues in comprehension and production. Eye-tracking revealed how FonF affects learners’ attention during online processing and thus modulates long-term blocking of verb morphology.

Abstract:

As per global accident statistics, human error accounts for over 85% of accidents. Therefore, human error analysis of cognitive behavior of operators can be the key to solving information interface design problems of digital smart task monitoring interfaces. This paper proposes an analytical method based on psychological experiments introduced into task monitoring interfaces to study reactions to error factors. It uses psychological techniques to conduct experiments which evoke physiological reactions to various error factors under different sub-interfaces of the monitoring system and sub-task environments. The behavioral and eye tracking data demonstrate the association between the error factors and the information interface. Error factors arising in visual search are directly related to the layout of the task-interface, the information proximity–position, and the information features-volume. Our method opens up new approaches for design optimizations of visual information interfaces and introduces novel concepts for the introduction of interface design via error factor analysis.

Abstract:

The spinal column requires special care through exercises focused on muscle strengthening, flexibility, and mobility to minimize the risk of developing musculoskeletal disorders that may affect the quality of life. Guidelines for spinal column exercises are commonly presented through printed and multimedia guides accompanied with demonstrations performed by a physiotherapist, occupational health expert, or physical fitness trainer. However, existing guides lack interaction and oral explanations may not always be clear to the user, leading to decreased engagement and motivation to start, continue, or complete an exercise program. In this article, we present two interactive and engaging posture-tracking user interfaces intended to promote proper spinal column exercise form. One user interface employs a wooden manikin with an integrated inertial measurement unit to provide a tangible user interaction. The other user interface presents a mobile application that provides instructions and explanations about the exercises. Both user interfaces allow recording key postures during the exercise for reference and feedback. We compared the usability of the interfaces through a series of flexion and extension exercises, monitored with an inertial measuring unit worn around the torso, and a Microsoft Kinect V2 vision-based sensor. Although no significant differences between the manikin user interface and the mobile application were found in terms of usability, the inertial measurement unit provided more accurate and reliable data in comparison to the Microsoft Kinect V2 as a result of body occlusions in front of the sensor caused during the torso flexion. Although both user interfaces provide different experiences and performed well, we believe that a combination of both will improve user engagement and motivation, while providing a more accurate motion profile.

Abstract:

The movements of fluid–fluid interfaces and the common curve are an important aspect of two-fluid-phase flow through porous media. The focus of this work is to develop, apply and evaluate methods to simulate two-fluid-phase flow in porous medium systems at the microscale and to demonstrate how these results can be used to support evolving macroscale models. Of particular concern is the problem of spurious velocities that confound the accurate representation of interfacial dynamics in such systems. To circumvent this problem, a combined level-set and lattice-Boltzmann method is advanced to simulate and track the dynamics of the fluid–fluid interface and of the common curve during simulations of two-fluid-phase flow in porous media. We demonstrate that the interface and common curve velocities can be determined accurately, even when spurious currents are generated in the vicinity of interfaces. Static and dynamic contact angles are computed and shown to agree with existing slip models. A resolution study is presented for dynamic drainage and imbibition in a sphere pack, demonstrating the sensitivity of averaged quantities to resolution.

Abstract:

The motion of interfaces for a mass-conserving Allen–Cahn equation that are attached to the boundary of a two-dimensional domain is studied. In the limit of thin interfaces, the interface motion for this problem is known to be governed by an area-preserving mean curvature flow. A numerical front-tracking method, that allows for a numerical solution of this type of curvature flow, is used to compute the motion of interfaces that are attached orthogonally to the boundary. Results obtained from these computations are favourably compared with a previously-derived asymptotic result for the motion of attached interfaces that enclose a small area. The area-preserving mean curvature flow predicts that a semi-circular interface is stationary when it is attached to a flat segment of the boundary. For this case, the interface motion is shown to be metastable and an explicit characterization of the metastability is given.

Abstract:

Abstract We investigated the unstable interface between vortices and anti-vortices in single crystals of iron-based superconductors (Ba0.67Rb0.33)Fe2As2 (Tc ∼ 37.6 K). These interfaces, also known as the Meissner hole, were captured with magneto-optical imaging in both pristine crystal and one with artificial point defects. Local excess current were observed flowing along the interface. In addition, we confirmed that the creep mode of such an interface follows the prediction of the critical state model, accompanied with a finite relaxation rate of magnetization.

Abstract:

In this paper, we describe two explorations in the use of hybrid user interfaces for collaborative geographic data visualization. Our first interface combines three technologies: augmented reality (AR), immersive virtual reality (VR), and computer vision-based hand and object tracking. Wearing a lightweight display with an attached camera, users can look at a real map and see three-dimensional virtual terrain models overlaid on the map. From this AR interface, they can fly in and experience the model immersively, or use free hand gestures or physical markers to change the data representation. Building on this work, our second interface explores alternative interface techniques, including a zoomable user interface, paddle interactions, and pen annotations. We describe the system hardware and software and the implications for GIS and spatial science applications.
