Abstract

Purpose

The purpose of this paper is the research of a novel gesture-based dual-robot collaborative interaction interface, which achieves the gesture recognition when both hands overlap. This paper designs a hybrid-sensor gesture recognition platform to detect the both-hand data for dual-robot control.

Design/methodology/approach

This paper uses a combination of Leap Motion and PrimeSense in the vertical direction, which detects both-hand data in real time. When there is occlusion between hands, each hand is detected by one of the sensors, and a quaternion-based algorithm is used to realize the conversion of two sensors corresponding to different coordinate systems. When there is no occlusion, the data are fused by a self-adaptive weight fusion algorithm. Then the collision detection algorithm is used to detect the collision between robots to ensure safety. Finally, the data are transmitted to the dual robots.

Findings

This interface is implemented on a dual-robot system consisting of two 6-DOF robots. The dual-robot cooperative experiment indicates that the proposed interface is feasible and effective, and it takes less time to operate and has higher interaction efficiency.

Originality/value

A novel gesture-based dual-robot collaborative interface is proposed. It overcomes the problem of gesture occlusion in two-hand interaction with low computational complexity and low equipment cost. The proposed interface can perform a long-term stable tracking of the two-hand gestures even if there is occlusion between the hands. Meanwhile, it reduces the number of hand reset to reduce the operation time. The proposed interface achieves a natural and safe interaction between the human and the dual robot.

Abstract

Purpose

This paper aims to propose and implement an integrated augmented-reality (AR)-aided assembly environment to incorporate the interaction between real and virtual components, so that users can obtain a more immersive experience of the assembly simulation in real time and achieve better assembly design.

Design/methodology/approach

A component contact handling strategy is proposed to model all the possible movements of virtual components when they interact with real components. A novel assembly information management approach is proposed to access and modify the information instances dynamically corresponding to user manipulation. To support the interaction between real and virtual components, a hybrid marker-less tracking method is implemented.

Findings

A prototype system has been developed, and a case study of an automobile alternator assembly is presented. A set of tests is implemented to validate the feasibility, efficiency, accuracy and intuitiveness of the system.

Research limitations/implications

The prototype system allows the users to manipulate and assemble the designed virtual components to the real components, so that the users can check for possible design errors and modify the original design in the context of their final use and in the real-world scale.

Originality/value

This paper proposes an integrated AR simulation and planning platform based on hybrid-tracking and ontology-based assembly information management. Component contact handling strategy based on collision detection and assembly feature surfaces mating reasoning is proposed to solve component degree of freedom.

Abstract

Purpose

The purpose of this paper is to employ a reflection on at-home ethnographic (AHE) practice to unpack the backstage messiness of an account to demonstrate how management students can craft fine-grained accounts of their practice and develop further our understanding of management practices in situ.

Design/methodology/approach

The paper reflects upon an example of AHE from an 18-month period at a chemical plant. Through exposure and exploration, the paper outlines how this method was used, the emotion involved and the challenges to conduct “good” research.

Findings

The paper does not seek to define “best practice”; it highlights the epistemic and ethical practices used in an account to demonstrate how AHE could enhance management literature through a series of practice accounts. More insider accounts would demonstrate understandings that go beyond distant accounts that purport to show managerial work as rational and scientific. In addition, such accounts would inform teaching of the complexities and messiness of managerial practice.

Originality/value

Ethnographic accounts (products) are often neat and tidy rather than messy, irrational and complex. Reflection on ethnographer (person) and ethnographic methodology (process) is limited. However, ethnographic practices are mostly unreported. By reflecting on ethnographic epistemic and ethical practices, the paper demonstrates how a largely untapped area has much to offer both management students and in making a fundamental contribution to understanding and teaching managerial practice.

Abstract

Purpose

Urban typogenetics investigates the use of machine intelligence for the evaluation of performance measures as a decision support system (DSS) with a focus on urban aesthetics evaluation. This framework allows designers to address performance measures, urban measures and aesthetic criteria in an adaptive, interactive generative design approach. The purpose of this paper is to provide an understanding of the structure and the nature of the framework and the application of human-in-the-loop design systems to urban design.

Design/methodology/approach

Significant literature reviewed lead to the identification of an application potential in the decision-making process. This potential is situated around the use of AI for the evaluation of subjective performance criteria in a DSS. Recognising that the key decisions about urban aesthetics are based on the individual evaluation of the designer, an HITL approach for computational design software to support creative decisions is presented in this paper.

Findings

Urban typogenetics for interactive generative urban design allows the exploration of complex design spaces by using a human-in-the-loop design system in the context of urban aesthetics. Hybrid aesthetic evaluation allows the designer to analyse morphological features and urban aesthetics during exploratory search and reveal hidden aspects of the urban context by visualisation of the results of the aesthetic evaluation. Integrating performance measures and urban aesthetics in urban typogenetics addresses major criteria of urban design at the beginning of the creative process.

Originality/value

The use of a broad interactive approach to typogenetic design in an application to urban scenarios is a novel conceptual approach to the design of urban configurations. The suggested adaptive mechanism would allow the user of a typogenetic tool to subjectively evaluate solutions by sight and reason about aesthetic, social and cultural implication of the reviewed design solutions.

Abstract

Purpose

This research theorizes the condition of human beings reduced to being users (and only users) in human-computer interaction (HCI), a condition that favors them becoming objects or targets of commercial dark patterns, racialized profiling algorithms, generalized surveillance, gendered interfaces and heteromation.

Design/methodology/approach

The reconceptualization of the users’ condition is done by confronting HCI theories on users with a dialectical-existential perspective over human ontology. The research is presented as a conceptual paper that includes analyzing and revising those theories to develop a conceptual framework for the user oppression in HCI.

Findings

Most HCI theories contribute to the user oppression with explicit or implicit ontological statements that denies their becoming-more or the possibility of users developing their handiness to the full human potential. Put together, these statements constitute an ideology called userism.

Social implications

HCI needs to acknowledge its role in structuring oppression not just in sexism, racism, classism and ableism, but also the specific relation that pertains to HCI: userism. Similar to other fields, acknowledging oppression is the first step toward liberating from oppression.

Originality/value

The user is an existential condition for HCI theories, yet few theories can explain in depth how this condition affects human development. From the dialectical-existential perspective, the user condition can be dehumanizing. Computers may intensify existing oppressions through esthetic interactions but these interactions can be subverted for liberation.

Abstract

Purpose

The main aim of this study is to explore the role of multi-dimensional human capital on the economic growth of the Indian economy.

Design/methodology/approach

The study used the methodology given by World Bank, 2018) in calculating the human capital index (HCI). The HCI has been constructed at a regional level for all 28 Indian states and 8 Union Territories (UTs) for the period of 2015–2016. The study explored the linkages between HCI and per capita gross state domestic product (PGSDP). The study further employed OLS (Ordinary Least Square) for overall significance and Spearmen’s Rank correlation coefficient test for establishing the linkage between HCI and PGSDP.

Findings

The results indicate that quality education, expected year of schooling, and infant mortality rate play a significant role in the improvement of HCI which further impacts the productivity rate of the upcoming generation and the inclusive growth of the country. The findings show that Mizoram, Chandigarh and Kerala are better performing states while the Bihar and Uttar Pradesh are the worst performers. The results also show that there is a positive and statistically significant correlation between PGSDP and HCI and its components. Further, the results show that public expenditure on health and education has significant effect on HCI.

Practical implications

The results of this study would be useful for policymakers to identify the determinants and improve the position of Indian states in HCI. The results show that policymakers should focus on quality education and health to improve the productivity of future generation workers for sustainable and inclusive growth.

Originality/value

The study is the pioneering study to analyze the state-wise HCI in India using methods mentioned by the World Bank. Unlike previous studies, variables such as expected year of schooling, under-5 mortality rates and survival rates are constructed more pragmatically.

This study aims to analyze the status and application/use of human–computer interaction (HCI) in libraries by conducting a systematic literature review (SLR).

Abstract

Purpose

This study aims to analyze the status and application/use of human–computer interaction (HCI) in libraries by conducting a systematic literature review (SLR).

Design/methodology/approach

A Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach was used to search Scopus, Web of Science and Google Scholar databases. The search criteria included research studies published in English language between 2010 and 2021, which were 4,167 citations. Out of 4,167 citations, a total of 50 studies were selected for the final analysis.

Findings

The results showed a positive attitude of librarians toward HCI applications in libraries worldwide. The results depict that one-third (30%) of the studies were conducted in the USA, followed by four (8%) studies in China. Out of 50 studies, a portion of 15 (30%) studies were based on digital libraries, followed by seven (14%) studies on academic libraries and five (10%) studies on libraries and their websites. HCI was used for searching and retrieving information, users’ interaction, authentication, online help/support, feedback, library web access, web OPAC, virtual access to resources, indigenous repository and virtual services. The most productive year was 2015, and journal of The Electronic Library had more articles on HCI than other journals.

Practical implications

The findings of this study could assist policymakers and library authorities in reconciling the HCI application in libraries for providing effective and efficient access and services to end-users.

Originality/value

This study is unique as no comprehensive study has been conducted on the use of HCI in librarianship using the SLR method.

Abstract

Purpose

This study aims to empirically analyse the influence mechanism of perceived interactivity in real estate APP which affects consumers' psychological well-being. With the growing application of human–machine interaction in real estate APP, it is crucial to utilize human–machine interaction to stimulate perceived interactivity between humans and machines to positively impact consumers' psychological well-being and sustainable development of real estate APP. However, it is unclear whether perceived interactivity improves consumers' psychological well-being.

Design/methodology/approach

This study proposes and examines a theoretical model grounded in the perceived interactivity theory, considers the relationship between perceived interactivity and consumers' psychological well-being and explores the mediating effect of perceived value and the moderating role of privacy concerns. It takes real estate APP as the research object, analyses the data of 568 consumer samples collected through questionnaires and then employs structural equation modelling to explore and examine the proposed theoretical model of this study.

Findings

The findings are that perceived interactivity (i.e. human–human interaction and human–information interaction) positively influences perceived value, which in turn affects psychological well-being, and that perceived value partially mediates the effect of perceived interaction on psychological well-being. More important findings are that privacy concerns not only negatively moderate human–information interaction on perceived value, but also negatively moderate the indirect effects of human–information interaction on users' psychological well-being through perceived value.

Originality/value

This study expands the context on perceived interaction and psychological well-being in the field of real estate APP, validating the mediating role and boundary conditions of perceived interactivity created by human–machine interaction on consumers' psychological well-being, and suggesting positive implications for practitioners exploring human–machine interaction technologies to improve the perceived interaction between humans and machines and thus enhance consumer psychological well-being and span sustainable development of real estate APP.

Abstract

Purpose

The purpose of this paper is to report findings from an interpretive case study on user participation in the open source software (OSS) development context.

Design/methodology/approach

Through an empirical, interpretive case study and a literature review utilising the metaphor of text in the analysis, this paper provides a refined conceptualisation of user participation in OSS development.

Findings

The paper reveals that different kinds of meanings have been attached to users and to their participation. User participation is both direct and indirect in the OSS development context. Some user groups actively take part in OSS development, while others are merely represented in it. Different kinds of intermediaries “representing the users” are identified.

Research limitations/implications

The research is based on one case study on a small but active OSS project with an interest in users. Other kinds of OSS projects should be analysed. The analysis was focused on a discussion forum, but users can take part in OSS development by other means as well. Paths for future work should include the gathering of more varied empirical data.

Practical implications

The findings indicate that users can provide feedback to the development through discussion forums in the distributed environment, but there is a need to support the users in doing so and the developers in analysing the data. The importance of different kinds of intermediaries “representing the users” is highlighted.

Originality/value

The paper provides thorough empirical insights and a refined conceptualisation of user participation addressing the currently weakly empirically explored OSS development context.
