Human-Computer Interaction Design for Emerging Technologies

This article presents a multifaceted case for the inclusion of the important Human-Computer Interaction (HCI) subject matter at both the graduate and undergraduate levels of the Association of Information Systems (AIS) model curricula. Based on the presentations and discussions during a panel at the 2003 Americas Conference on Information Systems (AMCIS), we first present the rationale for incorporating HCI materials in Management Information Systems (MIS) curricula. Second, we present a list of relevant and important HCI knowledge and skills that our students need for effective careers. Third, given the limited number of credit hours available to each MIS program, we explore several strategies and options for the integration of HCI into current and future MIS courses. Finally, drawing upon teaching experiences of the authors, we provide pedagogical suggestions for teaching HCI to undergraduate and graduate students.

UES-Br

The User Engagement Scale (UES) is a self-reported attitude scale broadly used in user research to measure their engagement with interactive systems, such as digital games and applications. The present work presents a translation of UES to the Portuguese language and its cultural adaptation to the Brazilian context. We followed five steps for the cross-cultural adaptation process: Translation, Synthesis, Back translation, Expert committee review, and Pretesting. Seeking to assure that the translated version is equivalent to the original in terms of metrics and semantics, we run tests on two data sets collected from 432 users' past experiences. As expected, T-tests for independent samples demonstrated that UES-Br provides significantly higher engagement experiences than scores for non-engaging experiences. An exploratory factor analysis indicated that most items were strongly correlated to the main factor (Engagement), showing a single underlying factor for all items. A Confirmatory Factor Analysis suggests that the original four-factor model provided an adequate fit to the data collected with UES-Br. The translation also demonstrated evidence of validity and reliability. This paper contributes to the global player- and human-computer interaction knowledge by enabling the Portuguese-speaking community to use a validated tool already established for native English speakers.

Designing Online Psychological Consultation Expert System Using Human-Computer Interaction

Traditional online psychological consultation expert system has low efficiency. It is because of limited human-computer interaction and lack of intelligence. As a result, an expert system for psychological consultation is needed. Therefore, in this paper, we design an online psychological consultation expert system based on human-computer interaction. Using human-computer interaction technology, the basic principles of the system’s design are formulated. The design is used to build a psychological consultation expert system framework suitable for numerous applications. Human-computer interaction knowledge is imported into the system to determine the consultation process based on fuzzy set. To complete the online psychological consultation preset, the adjustment of human-computer interaction accuracy is determined. Moreover, a psychological state of the user in human-computer interaction is achieved using the expression of psychological counseling results. Comparing the simulated psychological consultation process, the results show that the design system is 30% more efficient than the traditional consultation system. The consulting success rate is more than 20%. The comprehensive consultation time is shortened, and its effectiveness is proved.

The Digital Therapeutic Alliance and Human-Computer Interaction.

The therapeutic alliance (TA), the relationship that develops between a therapist and a client/patient, is a critical factor in the outcome of psychological therapy. As mental health care is increasingly adopting digital technologies and offering therapeutic interventions that may not involve human therapists, the notion of a TA in digital mental health care requires exploration. To date, there has been some incipient work on developing measures to assess the conceptualization of a digital TA for mental health apps. However, the few measures that have been proposed have more or less been derivatives of measures from psychology used to assess the TA in traditional face-to-face therapy. This conceptual paper explores one such instrument that has been proposed in the literature, the Mobile Agnew Relationship Measure, and examines it through a human-computer interaction (HCI) lens. Through this process, we show how theories from HCI can play a role in shaping or generating a more suitable, purpose-built measure of the digital therapeutic alliance (DTA), and we contribute suggestions on how HCI methods and knowledge can be used to foster the DTA in mental health apps.

Research on Optimization System of Radiotherapy Equipment from the Perspective of Human-Computer Interaction

Based on the knowledge of human-computer interaction, this paper deeply analyzes the human-computer interaction problems existing in China’s existing tumor radiotherapy equipment, and notices the lack of “patient-machine” interaction in the human-computer interaction system of radiotherapy. In response to this human-computer interaction problem, the interactive experience of tumor patients was analyzed by collecting questionnaire data. According to the “input-output” process, the interactive relationship between the patient and the machine in the radiotherapy space is decomposed into visual interaction, auditory interaction, tactile interaction and comfort to form a human-computer interaction optimization system based on the data analysis. It also provides an optimized direction for the existing human-computer interaction between radiotherapy equipment and patients.

Reflecting on the Design Process for Virtual Reality Applications

ABSTRACTA reflective analysis on the experience of virtual environment (VE) design is presented focusing on the human–computer interaction (HCI) challenges presented by virtual reality (VR). HCI design guidelines were applied to development of two VRs, one in marine archaeology and the other in situation awareness simulation experiments. The impact of methods and HCI knowledge on the VR design process is analyzed, leading to proposals for presenting HCI and cognitive knowledge in the context of design trade-offs in the choice of VR design techniques. Problems reconciling VE and standard Graphical User Interface (GUI) design components are investigated. A trade-off framework for design options set against criteria for usability, efficient operation, realism, and presence is proposed. HCI-VR design advice and proposals for further research aimed towards improving human factor-related design in VEs are discussed.

Age and domain specific usability analysis of opinion visualisation techniques

ABSTRACTThis study analysed the impact of age and domain knowledge on the usability of some of the state-of-the-art opinion visualisation techniques. A questionnaire survey was designed to ask the users’ level of agreement or disagreement about the selected opinion visualisation techniques against a set of information visualisation metrics. The data were collected by conducting seminars and using a web-based online questionnaire. We categorised participants (N = 146) into three age groups (≤20 years: teenager; 21–30 years: young adults; >30: adults). According to domain knowledge, participants are classified into two groups, one having knowledge of human computer interaction (HCI users) and the other without this knowledge (non-HCI users). The collected data were analysed using an independent sample t-test and analysis of variance. It is concluded that there are significant differences between the perception of HCI and non-HCI users on visual appeal, understandability, user friendliness, intuitiveness, informativeness, usefulness, comprehensiveness, comparison ability, and pre-knowledge requirement. Moreover, age was found to be significant for visual appeal, comprehensiveness, intuitiveness, and pre-knowledge requirement.

얼굴의 특이점 검출 및 실시간 추적을 이용한 e-Book 제어

This study is about e-Book program based on human-computer interaction(HCI) system for physically handicapped person. By acquiring background knowledge of HCI, we know that if we use vision-based interface we can replace current computer input devices by extracting any characteristic point and tracing it. We decided betweeneyes as a characteristic point by analyzing facial input image using webcam. But because of three-dimensional structure of glasses, the person who is wearing glasses wasn't suitable for tracing between-eyes. So we changed characteristic point to the bridge of the nose after detecting between-eyes. By using this technique, we could trace rotation of head in real-time regardless of glasses. To test this program's usefulness, we conducted an experiment to analyze the test result on actual application. Consequently, we got 96.5% rate of success for controlling e-Book under proper condition by analyzing the test result of 20 subjects.

The art of interaction

Interactive art has become much more common as a result of the many ways in which the computer and the Internet have facilitated it. Issues relating to human–computer interaction (HCI) are as important to interactive art making as issues relating to the colours of paint are to painting. It is not that HCI and art necessarily share goals. It is just that much of the knowledge of HCI and its methods can contribute to interactive art making. This paper reviews recent work that looks at these issues in the art context. In interactive digital art, the artist is concerned with how the artwork behaves, how the audience interacts with it and, ultimately, in participant experience and their degree of engagement. The paper looks at these issues and brings together a collection of research results and art practice experiences that together help to illuminate this significant new and expanding area. In particular, it is suggested that this work points towards a much needed critical language that can be used to describe, compare and discuss interactive digital art.

Modeling multimodal human-computer interaction

Incorporating the well-known Unified Modeling Language into a generic modeling framework makes research on multimodal human-computer interaction accessible to a wide range off software engineers. Multimodal interaction is part of everyday human discourse: We speak, move, gesture, and shift our gaze in an effective flow of communication. Recent initiatives such as perceptual and attentive user interfaces put these natural human behaviors in the center of the human-computer interaction (HCI). We've designed a generic modeling framework for specifying multimodal HCI using the Object Management Group's Unified Modeling Language. Because it's a well-known and widely supported standard - computer science departments typically cover it in undergraduate courses, and many books, training courses, and tools support it - UML makes it easier for software engineers unfamiliar with multimodal research to apply HCI knowledge, resulting in broader and more practical effects. Standardization provides a significant driving force for further progress because it codifies best practices, enables and encourages reuse, and facilitates interworking between complementary tools.

A Corporate Style Guide That Includes Domain Knowledge

Different professions adopt their own language such that the semantics involve elements very specific to their domain. System developers approaching users in a new domain often experience initial difficulties when trying to understand these semantics and associated work practices. Although most software developers also lack knowledge of human-computer interaction (HCI), means of transferring domain and HCI knowledge to developers in a convenient form are needed. A domain-specific style guide could be a worthy framework for the development of a high-level structure of interface elements and guidelines, including domain knowledge. Such a style guide is suggested as a practical form for packaging domain and HCI knowledge to aid developers. Anticipated benefits are enhanced application quality, usability, efficiency, and acceptance as the communication among software developers and intended users improves. The speed of application development could also increase. This article summarizes a project in which a medical style guide was developed and describes in more detail the work procedure utilized in the development of a corporate style guide for the tax-handling domain. Finally, suggestions on style guide development conditions are presented based on experiences from the establishment of the style guide in an organization.

Specifying relations between research and the design of human-computer interactions

This paper argues the need for more effective: human-computer interactions; design of such interactions; and research to support such design. More effective research for design would result in more effective human-computer interactions. One contribution to more effective research would be the specification of relations between research and the design of human-computer interactions. The aim of this paper is to propose such a specification. Frameworks for specifying relations are proposed for: disciplines; the human-computer interaction (HCI) general design problem; and validation. The frameworks are used to model, and so to specify, the relations: between HCI research and the HCI general design problem; and within the particular scope of HCI, to support HCI research. Together, the models specify the relations between HCI research and the design of human-computer interactions. Meeting these specifications renders HCI knowledge coherent, complete and “fit-for-design-purpose”. An illustration of the relations, thus specified, is provided by a model of the planning and control of multiple task work in medical reception and its hypothetical application. The same frameworks are also used to specify the relations between Cognitive Science and the understanding of natural and artificial forms of intelligence. Lastly, they are further used to identify the relations not specified between Cognitive Science and the design of human-computer interactions. The absence of such relations renders Cognitive Science knowledge not coherent, complete nor “fit-for-design-purpose” (as opposed to “fit-for-understanding-purpose”). It is proposed how the relations specified for HCI and Cognitive Science might be used in the assessment of relations between other research and the design of human-computer interactions. Finally, the paper recommends that such an assessment should be undertaken by any discipline, such as Cognitive Science, which claims a relation between its research and the design of human-computer interactions. Such an assessment would establish whether or not such relations are, or can be, specified. The paper concludes that specification of relations is required for more effective research support for the design of human-computer interactions.
