Abstract Incorporating human factors engineering guidelines early in design has the potential to reduce the cost and product lead-time to market. Also, products that go through strict ergonomics assessments are associated with better comfort and safety ratings. However, designers are often caught in the dilemma of what prototyping method to use when assessing product ergonomics early in design. This is especially problematic during the conceptual design phase before the physical prototypes are available or built. In this research, we explore the computational prototyping dilemma for early design ergonomics assessments from both fidelity and human-product interaction perspectives. In this paper, three computational prototypes with different fidelity levels (low, medium-, and high-fidelity) are compared in their adequacy for evaluating designs that comprise low- to high-levels of human-product interactions. We used three computational prototyping strategies: (1) Method #1 is a low-fidelity methodology based a digital sketchpad tool; (2) Method #2 is a medium-fidelity methodology consisted of computer-aided design and digital human modeling; and, (3) Method #3 is a high-fidelity methodology composed of computer-aided design, digital human modeling, and surrogate modeling. In order to perform computational ergonomics analyses using above approach, we selected a generic wall mounted cabinet design and a simplified Boeing 767 cockpit model as case studies to illustrate designs that require low- and high-levels of human-product interactions. Our preliminary results show that low-, medium- and high-level prototyping strategies produce similar ergonomics outcomes when evaluating low-level human-computer interaction (e.g., cabinet model). On the other hand, both low- and medium-fidelity (Method #1 and Method #2) prototyping strategies are limited in terms of providing detailed information about human performance when compared to high-fidelity prototyping (Method #3) in evaluating designs with high-level human-computer interaction (e.g., cockpit model).

Abstract Industry 4.0 promises better control of the overall product development process; however, there is a lack of computational frameworks that can inject human factors engineering principles early in design. This shortage is particularly crucial for prototyping of human-centered products where the stakes are high. Thus, a smooth Industry 4.0 transformation requires bringing computational ergonomics into the loop, specifically to address the needs in the digitized prototyping process. In this paper, a computational prototyping approach is explored that focuses on various fidelity levels and different human-product interaction levels when conducting ergonomics assessments. Three computational prototyping strategies were explored, including (1) a digital sketchpad based tool, (2) computer-aided design and digital human modeling based approach, and (3) a combination of computer-aided design, digital human modeling, and surrogate modeling. These strategies are applied to six case studies to perform various ergonomics assessments (reach, vision, and lower-back). It is suggest that designers must determine which fidelity level prototype to employ after applying a trade-off study between the accuracy of the ergonomics outcomes and the available resources. Understanding the intricacies between the fidelity level, type of ergonomic assessment, and human-product interaction level helps designers in getting one step closer to digitizing the human-centered prototyping in meeting Industry 4.0 objectives.

Abstract Background Contemporary dentistry is advancing toward computer-aided design/ computer-aided manufacturing (CAD/CAM) technology. But the budding dentists are unaware about the advancement. This survey aims at detecting the level of awareness among the undergraduate students and then correlating those results to modify the future curriculum. Objective The study aims (1) to assess the awareness among the dental undergraduate students and (2) to correlate the level of awareness among the third years, final years, and interns. Sample Selection Study sample consist of 300 students (third year students, final year students, and interns) of A. B. Shetty Memorial Institute of Dental Sciences, Mangalore, Karnataka, India. The information of the survey was collected with the help of a questionnaire. Results More than 70% of the students were aware about the basic functioning of CAD/CAM unit and approximately 74% of the students were unaware about the materials used to fabricate the prosthesis using CAD/CAM technology.

Abstract In this study, we examined student experiences surrounding the utilization of 3D printing for accessory production by fashion merchandising students enrolled in an Apparel Construction and Evaluation course at a historically Black university. The students designed and produced a sustainable 3D accessory prototype, and at the end of the course, completed a survey on their experiences surrounding drafting and the design-making process using computer-aided design (CAD). Faculty in the Apparel Construction and Evaluation course collaborated with Department of Technology faculty to help advance students' design skills in mass manufacturing in the fashion industry. Each student completed a month of impactful technology experience by creating sustainable prototypes of 3D accessories for their end-of-year fashion showcase held annually in the department. Results were compiled from student-completed surveys administered at the end of the course. This research was undertaken with the primary goal of assessing creative learning and was focused on three objectives: (1) to have students rethink and develop their own sustainable accessory line; (2) to provide students with real-world fashion accessory applications and (3) to increase students' understanding of computer-aided methods of design through 3D modeling, shapes and figures.

This chapter discusses the difficulties of CAD assessment through examining and reviewing existing CAD examination questions in Hong Kong. Based on the review, limitations of the current assessment are highlighted. It is argued that the existing method is inconsistent with the problem solving nature of the software and is unable to assess students with high ability and advanced drawing skills. Recommendation and improvement directions are suggested in the chapter to optimize the quality of assessment. Other subjects which also involve assessment of computer skills and design may also benefit from the recommendations.
