Abstract It is commonly recognized that the user interfaces of recent CAD systems do not effectively support creative man-machine communication in the conceptual phase of the design process. At the same time, speech, hand sketching, claying, etc. are appropriate tools for communicating ideas among designers. The inherent vagueness of verbalism and hand movement is both tolerable and requested for the human-computer interaction, as well. However, the natural format of communication may also permit unnecessary uncertainty, which can easily lead to significant failures in the understanding. The aim of the paper is to investigate how we can find those particular formats of natural communication that offer the benefit of communication of vague concepts and help to prevent failures of understanding. We have decided to use a simplified model of Gitt’s [5] information theory. We have selected three evaluation criteria (i.e., effectiveness, efficiency, and comfort) to facilitate the ranking of different ways of communication for a particular purpose. As a future work, we intend to accomplish the evaluation prove the evaluation by pilot implementation.

Cumulative Evidence

AbstractmiRNAs (or microRNAs) are small, endogenous, and noncoding RNAs construct of about 22 nucleotides. Cumulative evidence from biological experiments shows that miRNAs play a fundamental and important role in various biological processes. Therefore, the classification of miRNA is a critical problem in computational biology. Due to the short length of mature miRNAs, many researchers are working on precursor miRNAs (pre-miRNAs) with longer sequences and more structural features. Pre-miRNAs can be divided into two groups as mirtrons and canonical miRNAs in terms of biogenesis differences. Compared to mirtrons, canonical miRNAs are more conserved and easier to be identified. Many existing pre-miRNA classification methods rely on manual feature extraction. Moreover, these methods focus on either sequential structure or spatial structure of pre-miRNAs. To overcome the limitations of previous models, we propose a nucleotide-level hybrid deep learning method based on a CNN and LSTM network together. The prediction resulted in 0.943 (%95 CI ± 0.014) accuracy, 0.935 (%95 CI ± 0.016) sensitivity, 0.948 (%95 CI ± 0.029) specificity, 0.925 (%95 CI ± 0.016) F1 Score and 0.880 (%95 CI ± 0.028) Matthews Correlation Coefficient. When compared to the closest results, our proposed method revealed the best results for Acc., F1 Score, MCC. These were 2.51%, 1.00%, and 2.43% higher than the closest ones, respectively. The mean of sensitivity ranked first like Linear Discriminant Analysis. The results indicate that the hybrid CNN and LSTM networks can be employed to achieve better performance for pre-miRNA classification. In future work, we study on investigation of new classification models that deliver better performance in terms of all the evaluation criteria.

E Learning

The development of e-learning, both in distance and mixed forms, becomes especially relevant in the modern educational process. A high-quality e-learning course is developed through the efforts of two parties: the teacher, who creates the methodological content, and the programmer, who creates the electronic shell of the course. The article substantiates the importance of quality issues in the development of a user interface for electronic educational resources, since the user of an electronic course deals with the direct implementation of educational material. The indicators for assessing the quality of software products in accordance with international and Russian standards and their applicability for assessing user interfaces of electronic educational resources are analyzed. The conclusion is made about the importance of the indicator “practicality” in relation to this type of software product as an indicator of an individual evaluation of the use of a product by a certain user or circle of users. The classical methods for assessing the quality of the human-machine interaction interface and the applicability of experimental and formal methods for assessing quality are considered. The analysis of modern approaches to the design of user interfaces based on UX/UI design is given. An assessment of the requirements and criteria for assessing the user interface from the standpoint of modern design is given. The tasks and features of the UX and UI components of the design process are analyzed. The essence of the modern term “usability” as an indicator of the interface evaluation is explained, and the qualitative evaluation criteria for this indicator are considered. The concept of UX testing is given, the main stages of this process are considered. The importance of taking into account the subjective psychological factors of interface perception is substantiated. The indicators for assessing the quality of user interfaces, based on the cognitive factors of its perception by a person, are analyzed.

A mental state is luminous if and only if being in a state of that kind always puts one in a position to know that one is in the state. This chapter is a critique of Timothy Williamson’s margin-of-error argument that no nontrivial states are luminous in this sense. While I agree with Williamson’s rejection of a Cartesian internalist conception of the mind, I argue that an externalist conception (one based on information theory) can be reconciled with the luminosity of intentional mental states such as knowledge. My argument, which uses an artificial and simplified model of knowledge, is not a direct rebuttal to his argument, as applied to a more realistic notion of the knowledge of human beings, but I argue that it shows that a luminosity assumption is compatible with externalism about knowledge, and it suggest an intuitively plausible strategy for resisting his argument.

This research aims to create a new approach for spider maps production that results in a fast and automatic method having as input only network location data. Schematization task is commonly done by hand or by purely graphics software. This is a difficult and time consuming task that also needs a skilled map designer, which results in an expensive outcome. A configurable force-directed algorithm allows fast creation of eye-pleasing schematic maps, avoiding labor-intensive manual arrangement. In the other hand, different sets of design rules and constraints may be used to quickly generate alternatives, and allow the configuration of a distinctive graphic style. This document presents some of the rules and constraints that may be used to output a map that meets certain criteria in order to be used as a spider map in transportation systems. We present results with real public transport network datasets, and discuss possible evaluation criteria. The present work introduces a new set of experimental validations that confirm the previous research but also leading to new open issues for future work.

The rapid development of mobile user interfaces for students’ websites and the constant utilization of such interfaces by students have witnessed a significant upsurge in growth. However, mobile service providers may lack valuable feedback on user satisfaction, particularly for Arabic users, because the sites are designed and implemented without students’ participation. This paper empirically investigates the user satisfaction of a mobile banner system for the University of Ha’il in Saudi Arabia. Users’ satisfaction was evaluated across six scales: overall reactions, screens, terminology and system information, learning, system capabilities, and technical manuals and online help. A quantitative research method was utilized, involving a questionnaire survey of 235 students. We found that female students have significant concerns about user satisfaction. The paper proposes theoretical and practical implications for future work.

Route Search

Electric vehicles (EVs) have numerous inherent challenges, including running out of power frequently and taking a long time to charge. To make matters worse, current automotive navigation systems cannot provide proper route searches that include charging plans. One way to tackle these challenging problems is to propose several route plans and select one which meets the driver’s needs. In this paper, the following three evaluation criteria are proposed: shortening travel time by predicting charging queues, maintaining high residual capacity of the battery, and utilizing charging time. The proposed method is applied to Okinawa, Japan as a case study. The simulation results using this evaluation method in Okinawa demonstrate its potential utility and open the way for future work on relieving the stress of EV drivers.

Transient use of information visualization may support specific tasks without permanently changing the user interface. Transient visualizations provide immediate and transient use of information visualization close to and in the context of the user’s focus of attention. Little is known, however, about the benefits and limitations of transient visualizations. We describe an experiment that compares the usability of a fisheye view that participants could call up temporarily, a permanent fisheye view, and a linear view: all interfaces gave access to source code in the editor of a widespread programming environment. Fourteen participants performed varied tasks involving navigation and understanding of source code. Participants used the three interfaces for between four and six hours in all. Time and accuracy measures were inconclusive, but subjective data showed a preference for the permanent fisheye view. We analyse interaction data to compare how participants used the interfaces and to understand why the transient interface was not preferred. We conclude by discussing seamless integration of fisheye views in existing user interfaces and future work on transient visualizations.

Abstract This paper reports on a research effort involving design of a class of significantly complex products — nuclear submarines. It focuses on the use of features as a means of design abstraction, and it is found that a principal motivation for the use of features in this design environment is the convenience of the early stage submarine designer. To support this argument, a review of feature research is presented. Experiments in the development of feature catalogs are described, and implementation through two generations of feature based submarine CAD systems are discussed. The architecture of the feature based submarine CAD systems includes the use of Microsoft Foundation Classes (MFC), the ACIS geometric modeler, and user interfaces which store/recall hierarchical submarine feature information easily. Strong connections to object-oriented programming and object-oriented databases are recognized. Conclusions are drawn regarding the use of features for designer convenience and regarding support provided by hierarchical, parameterized features for other means of design automation.

And Task

We introduce an unobtrusive, computational method for measuring readiness-to-hand and task-engagement during interaction."Readiness-to-hand" is an influential concept describing fluid, intuitive tool use, with attention on task rather than tool; it has longbeen significant in HCI research, most recently via metrics of tool-embodiment and immersion. We build on prior work in cognitivescience which relates readiness-to-hand and task engagement to multifractality: a measure of complexity in behaviour. We conduct areplication study (N=28), and two new experiments (N=44, N=30), which show that multifractality correlates with task-engagement and other features of readiness-to-hand overlooked in previous measures, including familiarity with task. This is the first evaluation of multifractal measures of behaviour in HCI. Since multifractality occurs in a wide range of behaviours and input signals, we support future work by sharing scripts and data (https://osf.io/2hm9u/), and introducing a new data-driven approach to parameter selection

This chapter introduces a standards-based and adaptive framework whose main objective is to adapt user interfaces, content and learning environment to learners’ needs, including their functional diversity issues (i.e., disabilities). The framework is intended to be general (e.g., two different learning management systems and two large pilot sites are being considered) and to that end it is implemented in terms of an open architecture, which aims at providing services for Accessible Lifelong Learning. The chapter focuses on accessibility and adaptation issues, and their interoperability requirements. The covered topics are the required standards, interoperability requirements of the architecture, user model, recommender system, and their application to the end-user services that are being implemented at UNED University, one of the large pilot sites of the EU4ALL European project. Some of the challenges and solutions provided are discussed as well as the future work of related research areas.
