Academic library innovation through 3D printing services

Applications of metaverse-related technologies in the services of US urban libraries

Purpose

The purpose of this paper is to understand the applications of metaverse-related technologies in US urban libraries, explore excellent cases of US urban libraries' practices in using metaverse-related technologies to serve patrons and try to find the factor that may affect the application of metaverse-related technologies in libraries at this stage.

Design/methodology/approach

To gather information about how and whether libraries use metaverse-related technologies such as three-dimensional (3D) technology, radio frequency identification (RFID), virtual reality augmented reality (AR) and artificial intelligence (AI) in their services. Firstly, the authors visit 150 US urban library websites that are members of the Urban Libraries Council. Secondly, the authors calculate the proportion of services provided by urban libraries that use metaverse-related technologies and introduce outstanding cases. Lastly, the authors discuss the factors that influence the application of metaverse-related technologies in urban libraries in the United States based on data published by the Institute of Museum and Library Services.

Findings

Metaverse-related technologies have been widely used in US urban libraries, but there are differences in the popularity of the applications of different technologies. In all, 84% of libraries use 3D technology, mainly in 3D printing services and 3D model building services; 76% of libraries use virtual and augmented reality technologies in their services, mainly concentrated in head-mounted VR device experiences, AR device experiences, virtual tours and virtual exhibitions; 62% of libraries use Internet of things (IoT) technology, mainly in self-checkout machines and book location services. However, AI technologies are less used in libraries, with 28% of libraries mentioning the applications of AI in their services, mainly focusing on intelligent search, virtual assistants and robot librarians. In addition, this study finds that library operating expenditures and population served do not affect the application of metaverse-related technologies in libraries.

Originality/value

This paper provides updated statistical data on the use of metaverse-related technologies in US urban libraries and aims to help library managers understand the overall applications and best practices. With this as an inspiration, they could formulate corresponding development plans to better serve their communities with metaverse-related technologies.

Tutorials for Integrating 3D Printing in Engineering Curricula

Three-dimensional (3D) printing can revolutionize the way products have been designed and manufactured. This necessitates engineering graduates equipped with the knowledge and skills of 3D printing. As a result, the educational aspects of 3D printing have earned a great deal of attention. Nevertheless, to teach 3D printing in an undergraduate engineering degree program, an outcomes-oriented approach integrating engineering design, object visualization/digitization, and 3D printing domains can be used. Accordingly, this study presents a tutorial development method to teach undergraduate engineering students the knowledge and skills of 3D printing. The method integrates the abovementioned domains maintaining a hierarchy among the seven ABET-prescribed outcomes. The hierarchy organizes the outcomes into three levels (primary, secondary, and tertiary). The presented method is implemented by introducing a tutorial where a spur gear-pinion pair is designed, visualized, digitized, and 3D printed systematically. E-learning tools can be developed to deliver the tutorial online.

Geometric Modeling and 3D Printing Using Recursively Generated Point Cloud

Previous studies have reported that a recursive process called the point cloud creation algorithm (PCA) that generates a point cloud is useful for reverse engineering a planner shape. This study elucidates the characteristics of the parameters used in the recursive process as well as its ability in geometric modeling and 3D printing of 3D shapes. In the recursive process, three constants (center point, initial distance, and initial angle) and two variables (instantaneous distance and instantaneous rotational angle) are employed. The shape-modeling characteristics of the constants and variables are elucidated using some commonly used shapes (straight-line, circle, ellipses, spiral, astroid, S-shape, and leaf-shape). In addition, the shape-modeling capability of the recursive process as a whole is quantified using two parameters called the radius of curvature and aesthetic value. Moreover, an illustrative example that shows the efficacy of the recursive process in virtual and physical prototyping of a relatively complex 3D object is presented. The results show that reverse engineering performed by the recursive-process-created point cloud is free from computational complexity compared to reverse engineering performed by the 3D-scanner-created point cloud. As such, the outcomes of this study enrich the field of reverse engineering.

How to design innovative information services at the library?

Purpose

The subject of the paper is innovative information services. The purpose of this paper is to identify the potential sources of innovation in library information services and point out how they can be used to improve the overall service quality.

Design/methodology/approach

In the first stage, literature analysis and critique was used to establish the state of research in the field of innovative solutions and select the main sources of innovation in services. Next, a systematic search of the subject literature and network resources was carried out according to the selected criteria to find the examples of innovative commercial services, particularly in the information sector.

Findings

Libraries, like all customer-oriented service organizations, must innovate and continually evolve to better meet the needs of their audience. It seems that in libraries, the basis of innovation and building a competitive advantage over other institutions may primarily be the thoughtful design of services in the spirit of the assumptions of the experience economy. Innovative ideas based on in-depth knowledge of user needs are less dependent on financial conditions and more on the creativity and enthusiasm of library staff.

Research limitations/implications

This paper is a conceptual work presenting the issue of innovation from the perspective adopted by the author. The paper does not aim to fulfill the subject but to show some interesting aspects of this issue and help initiate discussions on innovation in libraries from the perspective of phenomena present on the commercial information services market. This approach, which has not yet been adapted in library science, may show some new aspects and lead to new conclusions. This is a literature review type of paper that is not based on empirical research and it has not yet been tested in practice; however, the author believes that it can provide a valuable framework for designing and implementing innovative services in libraries. The presented process is a preliminary proposal that can and should be modified in the future based on further scientific reflection and examples of implementations in libraries.

Practical implications

The results can be widely used in practice as a framework for designing innovative services in libraries. The paper, based on subject literature, proposes a process of designing innovative information services that can and should be tested in practice.

Social implications

The paper can help initiate the debate on the need to implement innovative solutions in library services.

Originality/value

The issue of innovation in library services has not yet been widely discussed in library and information science journals from the perspective proposed by the author. This paper presents a specific approach to library innovation based on the observation of the certain phenomena on the commercial market, which opens the door to new reflections.
