The purpose of this study is to discuss approaches for developing human–computer interaction (HCI) in educational technology (ET) based on definitions of visual design, learning variables and user-interface design principles in the field of instructional design and technology (IDT). We will do in several stages, first, we will review historical definitions of HCI and its developments in education and considerations for defining visual literacy for learning with instructional design (ID) models. Then, we will review each definition of visual principles for user interface design (UID) or user experience design (UED) and learning from screens. HCI and its roles with the perceptional approach will be discussed as previous definitions in the type of theories such as cognitive load, activity and paying particular attention to primary concepts included in each definition based on the ID model approach. We will also present some of the historical criticisms of the definitions, which provided designing and developing user interfaces. The process should indicate or address possible performance design approaches in ID steps for developing learning and teaching in learning environments as well as developing UID or UED in ET. This also indicates approaches in philosophy of ET and its theory, definition and applications of new technologies as well as UID or UED perspectives and visual design variables. In this study, we review the visual design techniques from past to present that multimedia project design teams should follow the strategies and rules for designing learning environments in industry, business and military based on philosophy of ET and HCI design with ID models by using the newest technologies. The process compares both understanding global UID or UED requirements and visual strategies and considerations for research and product design by ID models. The steps include recognising terminology in ET practice concept, psychological, technological and pedagogical foundations in ID as well as ET approaches and using visual rules for conducting multimedia projects in last decays. At the end of the study, conceptions of ET, ID models and HCI will be discussing to indicate design standards for multimedia projects in the field of IDT. We will also present the relationships between ET and designing problems for creating instructional materials in education. All steps in visual design, UID, UED and HCI design based on philosophical approaches and evaluations in the field are given at the end of the study.

In this paper, a method-mix (cultural dimensions, intercultural variables, user interface characteristics and human computer interaction (HCI) dimensions) for intercultural user interface design (IUID) is presented. Based on a hybrid approach covering cultural contexts in human–computer interaction (HCI) design using a model of culturally influenced HCI, this IUID method-mix represents the main constituent of a reasonable toolbox for IUID. The IUID method-mix is exemplified by application examples to demonstrate and discuss its benefit and limitations. The examples elucidate why and how cultural aspects play a role in HCI design and usability/UX engineering. Cultural influence on HCI is described using cultural variables for user interface design. The IUID method-mix serves to inspire HCI engineers in the requirement analysis phase as well as HCI designers in the design phase. The readers are sensitized to the challenges of intercultural usability/UX engineering and intercultural HCI design and will be equipped with relevant methodological knowledge needed to actively derive design recommendations for user interface design for and in their desired cultural contexts. Practitioners can prognosticate the ensuing effort and the expenditure for considering cultural context in intercultural user interface design.

Digital devices and online services are increasingly embedded within our everyday lives. The growth in usage of these technologies has implications for environmental sustainability due to the energy demand from the underlying Internet infrastructure (e.g. communication networks, data centres). Energy efficiencies in the infrastructure are important, but they are made inconsequential by the sheer growth in the demand for data. We need to transition users’ Internet-connected practices and adapt HumanComputer Interaction (HCI) design in less demanding and more sustainable directions. Yet it’s not clear what the most data demanding devices and online activities are in users’ lives, and how this demand can be intervened with most effectively through HCI design. In this thesis, the issue of Internet demand is explored—uncovering how it is embedded into digital devices, online services and users’ everyday practices. Specifically, I conduct a series of experiments to understand Internet demand on mobile devices and in the home, involving: a large-scale quantitative analysis of 398 mobile devices; and a mixed-methods study involving month-long home router logging and interviews with 20 participants (nine households). Through these studies, I provide an in-depth understanding of how digital activities in users’ lives augment Internet demand (particularly through the practice of watching), and outline the roles for the HCI community and broader stakeholders (policy makers, businesses) in curtailing this demand. I then juxtapose these formative studies with design workshops involving 13 participants; these discover how we can reduce Internet demand in ways that users may accept or even want. From this, I provide specific design recommendations for the HCI community aiming to alleviate the issue of Internet growth for concerns of sustainability, as well as holistically mitigate the negative impacts that digital devices and online services can create in users’ lives.

<p>This dissertation discusses human-computer interaction, and the role of user interfaces in use and design from the point-of-view of human activity theory. Human-computer interaction conducted in purposeful human work is in focus. The main idea is that a computer application, from the user's perspective, is not something that the user operates on but something that the user operates through on other objects or subjects.</p><p>The contents of the report is the following: Danish Summary; Introduction; Human Activity and Human-Computer Interaction; User Interface Design -- the Empirical Cases; User Interfaces; Methods for User Interface Design; User Interface Design -- Advice to the Designer.</p>

To attract more users and promote purchase habits, social e-commerce platforms constantly propose new interaction techniques and marketing strategies. "Xiaohongshu" immediately became famous due to its popular "grass-planting" function. The platform established the "Sales through note-sharing" approach to interrupt the cycle of "planting without uprooting." The purpose of this study is to investigate the factors influencing online purchase intention of the "Xiaohongshu" Sales through note-sharing model from a human-computer interaction standpoint, as well as the relationships between these factors. To do this, we expanded on the TAM model by including five variables: social identity, social comparison, and knowledge sharing Willingness, interface design, and purchase intention form 12 hypotheses. We gathered 287 valid replies from "Xiaohongshu" users and tested them with SPSS and AMOS. According to the study findings, interface design has a greater impact on purchase intention than knowledge-sharing willingness and behavioral intention to use. Interface design significantly influences knowledge sharing Willingness and social identity significantly influence social comparison, which in turn significantly affects interface design. These results underscore the crucial role of interaction factors, particularly interface design, in purchase intention and the Sales through note-sharing model. This suggests that "Xiaohongshu" can enhance the Sales through note-sharing model by improving interface design to further enhance users' purchase intention and solidify the "grass-planting and uprooting" loop. In theoretical terms, this study extends the TAM model by integrating social factors (social identity, social comparison, knowledge sharing willingness) and interaction factors (interface design), enriching research in the fields of online purchasing and human-computer interaction on social e-commerce platforms. It also provides relevant insights for stakeholders.

1983: The first CHI called CHI - computers just processed data and Human-Computer Interaction (HCI) just supported users in their work tasks.Twenty years on, broadband servers and mobile devices now outnumber desktop office machines. With them come joy, persuasion, outrage, delight, faith, campaigns, satire, fun, learning, identity, communities, and passion. Now, increasingly, we interact to be, not just to do. Interaction no longer just changes things, it changes people. HCI is headed for New Horizons.CHI 2003 recognised this sea of change in HCI and addressed all forms of interactive digital communication, with a focus on three special areas: mass communication and interaction, e-learning, and emotion. Many presentations addressed these special areas. Still, CHI 2003 has not abandoned established HCI for New Horizons! Everything you'd expect to find in a CHI conference is still here.These Conference Proceedings contain the papers accepted for presentation at CHI 2003. Competition was fierce. 470 submissions were received, and 75 were accepted. Many of these accepted papers address the challenge of supportive effective and enjoyable communication via interactive digital media.A CD containing the extended abstracts for short talks, demonstrations, design and usability in practice papers, special interest group descriptions, interactive posters, student posters and doctoral consortiumpresentations accompanies these proceedings. Video figures and demonstrations are provided on an additional DVD. These complete the record of CHI 2003 as the meeting place for an inclusive community, The CHI conference is the annual gathering of the world's HCI community. There is something for everyone. Students, researchers, professionals, and educators are spoiled for choice.

The use of metaphor is essential in user interface design, particularly for the mobile landscape, as the visual environment continues to be populated with more and more mobile electronic devices. A metaphor allows us to understand one concept in terms of another. Although considerable research has gone into the mobile technology, little attention has been paid to mobile interface metaphor, which is the key to user interaction. This paper explores the role of metaphor in interfaces in facilitating user interaction with mobile devices. It presents a classification of metaphors. It also proposes a framework with salient factors in relation to visual communication with metaphors. It also offers some thoughts on the use of new metaphors.

Electronic Government (e-Government) systems are intended primarily to deliver governmental information and services through the web. The rapid evolution of mobile technology has triggered the need for conventional web-based e-Government systems to move towards another era known as Mobile Government (m-Government) systems. Although the functionality remains the same, the use of mobile devices in m-Government systems has caused the interface design of such systems to be dissimilar from the conventional web-based e-Government systems. Mobile devices in some ways have limited capacity in terms retrieving and displaying information, which makes their interface design to be quite tricky. This study aims to review the existing interface design frameworks in order to identify and collate the essential design elements that should be considered in designing the interface for m-Government systems. The study analysed qualitatively four m-Government interface design frameworks, namely 7Cs Design Elements, A Functional Design Approach for Mobile Government Website, Adaptive Mobile Government Framework and Framework of information Quality of Mobile Interface e-Government. By using content analysis, the study identified eight design elements from such frameworks. The study also highlighted the limitations of the current frameworks that could be explored further by future studies in interface design for m-Government systems.

A Web-Based Perioperative Dashboard as a Platform for Anesthesia Informatics Innovation.

The context in which a device is used has a major impact on mobile device design. Despite this, there are few system design methods that assist user interface designers to represent use context in a useful and systematic manner throughout the whole design process. Current scenario-based design approaches are able to represent context, but still present a challenge to support a shared understanding of the rich context in which activities take place and in encoding dynamic use context due to time issues such as sequential and parallel actions. This paper reports on a method called Picture Scenarios. The method was used by four design teams whilst designing mobile information devices for use in a public square. Results show that picture scenarios provide an effective way of communicating and debating use context with design partners. The suggested format of the picture scenarios facilitates to represent use context during design activities in a systematic way. These scenarios are easy to create, easy to use, and capture important contextual details about activity that is difficult to represent otherwise.

Human Computer Interaction (HCI) based interface modeling techniques can be employed in designing interactions. They provide complete mechanism for the design of an interactive interface in analysis and design phases of interface development. Interface design using these techniques incorporates usability and utility aspects. Object Action Interface (OAI) model is an interaction modeling technique. Our investigation revealed that existing model lacks interface responses, change of the interface states, relationship among interface constructs and mapping of sequence of actions on sequence of objects. OAI model may not be efficiently employed in designing interactions due to the investigated shortcomings. In this study we propose an enhancement in the existing OAI model. Response is introduced in the existing OAI model that will provide an improved mechanism for the design of interactions. The proposed mechanism can be employed as a new interface modeling paradigm. This modeling paradigm will lead to better interface response, improved relationships among interface constructs and better mapping of sequence of actions on sequence of objects.

A framework for bimanual inter-device interactions

We describe a method of assessing the implications for human error on user interface design of safety-critical systems. In previous work we have proposed a taxonomy of influencing factors that contribute to error. In this article, components of the taxonomy are combined into a mathematical and causal model for error, represented as a Bayesian Belief Net (BBN). The BBN quantifies error influences arising from user knowledge, ability, and the task environ-ment, combined with factors describing the complexity of user action and user interface quality. The BBN model predicts probabilities of different types of errorslips and mistakes for each component action of a task involving user-system interaction. We propose an Impact Analysis Method that involves running test scenarios against this causal model of error in order to determine user interactions that are prone to different types of error. Applying the proposed method will enable the designer to determine the combinations of influencing factors and their interactions that are most likely to influence human error. Finally we show how such scenario-based causal analysis can be useful as a means of focusing on relevant guidelines for safe user interface design. The proposed method is demonstrated through a case study of an operator performing a task using the control system for a laser spectrophotometer.We describe a method of assessing the implications for human error on user interface design of safety-critical systems.
