Abstract Current prototyping frameworks are often prompt-based and heavily rely on designers’ experience. The lack of systematic guidelines in prototyping activities causes unwanted variation in the quality of the prototype. Notably, there is limited, or no prototyping framework exists that enables human factors engineering (HFE) guidelines be part of the early product development process. In this paper, a pre-prototyping framework is proposed to render human-centered design strategies to guide designers before the hands-on prototyping activity starts. The methodology consists of extracting key factors related to prototyping and human factors engineering principles based on an extensive literature review. The key elements are then combined to form the prototyping categories, dimensions (theory), and tools (practice). The resulting prototyping framework can be used to develop prototyping strategies consist of theoretical guidelines and practical tools that are needed during the prototyping of human-centered products. The framework provides systematic guidance to designers in the early stages of the design process so that designers, in particular novices in ergonomics and human factors, can have a head start in building the prototypes in the right direction. Finally, a case study is presented to demonstrate a walk-through and efficacy of the proposed pre-prototyping framework.

Higher education is one of the key factors in the effort to improve the lives and well-being of a nation. The experience of developed countries in Asia showed that the quality of higher education correlated significantly with the increased competence of human resources as a whole which eventually forms a high competence in the global competition. Globalization proactively answered by the governments in various parts of the world through international cooperation in the form of teaching, research, and dedication to the university in the form of the internationalization program. Through descriptive qualitative method enriched by quantitative techniques with intrinsic case study design (intrinsic case study), this research found that the success of internationalization is driven by capacity building supported by horizontal and hands on leadership. Therefore, the leadership of a university is not only an academic but it must be a manager who is able to read the signs of change.

This paper describes the application of affordable program management software to the task of planning human factors programs conducted in support of complex system developments. A model of the military system acquisition process was developed and a model human factors engineering program was overlayed upon it. Interdependencies were created between the models so that changes made in the acquisition schedule would cause the human factors program to be automatically tailored. This approach has potential to reduce planning time and increase the quality of human factors plans.

Wheel Brake

A survey was made of the braking techniques reportedly used by 180 motorcyclists in a variety of conditions. Overall, the motorcyclists indicated that they used both front and rear brakes in hard braking 75% of the time on dry pavement and 47% on wet, but in other conditions they mostly used the rear brake first or exclusively. That the rear brake is preferred is not surprising because of the design of the brake controls and other reasons. Reliance on the rear brake at the expense of the front wheel brake leads to reduced deceleration. A crash case study exemplifies the effect. Integrated brakes, in which each brake control simultaneously activates the brakes on the front and rear wheels, are indicated by good human factors design and by motorcyclist's braking performance and should improve safety, especially when the brakes incorporate anti-locking mechanisms

The Military

Ergonomics (a synonym for human factors engineering) has contributed significantly to fundamental effectiveness of people, but needs a new emphasis and wider applications in future. A basic distinction is drawn between the areas of application and the focus of ergonomists. Although applications have been relatively successful in the military and industrial fields, ergonomics should also be applied to consumer products, architecture, transportation and recreation. In future, the primary challenge will be to improve the "quality of life" by enhancing human satisfaction and allowing people to function at higher value levels. In work activities the basic task of ergonomics has been to simplify and standardise jobs, but future focus should be on enlargement and enrichment of jobs. Because of individual differences probably not all jobs could be made completely satisfactory to all workers. However, significant contributions could be made through continued efforts to “humanise” work activities.Opsomming Ergonomika ('n sinoniem vir "human factors engineering") het reeds heelwat bygedra tot die doeltreffende funksionering van die mens, maar nuwe gesigspunte en toepassingsvelde sal in die toekoms nodig wees. 'n Fundamentele onderskeid word getref tussen die gebiede van toepassing en die fokus van beoefenaars van die ergonomika. Hoewel toepassings in die militêre en industriële sfere redelik suksesvol was, behoort ergonomiese beginsels ook op verbruikerswese, argitektuur, vervoer en ontspanning toegepas te word. Die grootste uitdaging in die toekoms sal egter wees om "lewenskwaliteit" te verbeter deur tevredenheid te verhoog en mense te help om doeltreffender te leef en in die proses hoër waardevlakke te handhaaf. In werksaktiwiteite was die hoofdoel tot dusver om werk te standaardiseer en te vereenvoudig, maar dit word al hoe noodsaakliker dat poste verruim en verryk moet word. Waarskynlik sal alle poste nie vir alle bekleërs volkome bevredigend gemaak kan word nie, maar dit sou tog nuttig wees om heelwat meer aandag aan die "humanisering" van werksaktiwiteite te gee.

Recognizing the role of human factors engineering (HFE) in the development of medical devices and combination products that involve devices, the Food and Drug Administration (FDA) now requires human factors (HF) validations before market approval. Manufacturers are responsible for ensuring their products are safe and effective through the application of HFE. However, key stakeholders are still learning and developing capabilities to adapt to the regulatory component. Nonetheless, the lack of the corresponding HF capabilities hinders compliance with the FDA’s expectations, and though ultimate success. No known previous work has looked into FDA HF validation projects to assess the underlying factors and implications of failed submissions. Applying system dynamics (SD), a causal loop diagram (CLD) was developed. CLDs are useful for the exploration of the causal interactions among factors or variables, as well as the underlying feedback structure of a complex system. This work can serve to help manufacturers better understand the FDA’s HF requirement to enable overall product success. Further, with patient safety as a common goal, HF service providers (HFSPs) and regulators should be aware of the need to ensure the consistent quality of the HF element in premarket submissions.

Development of implantable medical devices is becoming increasingly interesting for manufacturers, but identifying the right Human Factors Engineering (HFE) approach to ensure safe use and effectiveness is challenging. Most active implantable devices are highly complex; they are built on extremely advanced, compact technology, often comprise systems of several device elements and accessories, and they span various types of user interfaces which must facilitate diverse interaction performed by several different user groups throughout the lifetime of the device. Furthermore, since treatment with implantable devices is often vital and by definition involves surgical procedures, potential risks related to use error can be severe. A systematic mapping of Product System Elements and Life Cycle Stages can help early identification of Use Cases, and for example user groups and high-level use risks, to be accounted for via HFE throughout development to optimize Human Factors processes and patient outcomes. This paper presents a concrete matrix tool which can facilitate an early systematic approach to planning and frontloading of Human Factors Engineering activities in complex medical device development.

This paper illustrates some of author's views of the ergonomics implementation challenges within diverse industries, manufacturing, office environments, and machinery/product design. We intend to analyze and review the roots of problems from different perspectives and recommend which ergonomics approaches are likely to succeed or fail. Most importantly it is imperative to find the actual cause(s) of obstacle(s) - problem(s) before looking for appropriate ergonomics solution(s) and acceptance of ergonomics innovations by end users. The presented material is based on the substantial authors' experiences in human factors engineering and ergonomics, in industry and academia and in various countries. Our objective is to present an integrated view of ergonomics within corporate bureaucracy in the contexts of favorable and unfavorable environments - factors that lead to success or failure.

The Tallinn Manuals (the Manuals) attempted to clarify how to apply existing international law to cyber operations. Though the Manuals are non-binding instruments, the Group of International Experts claimed that they reflected the lex lata applicable to cyber operations. However, this claim is questionable due to the dominating role of a few Western states in the drafting process and the linked neglect of the practice of “affected states” in cyber operations. This article examines the quality of the Manuals’ drafting process and the composition and impartiality of the experts involved. It focuses on the issue of the prohibition of the use of force. The aim of this examination is not to discuss whether the Manuals provided the right answer to the question of how international law applies to cyber operations. Rather, they function as a case study of how legal scholarship may affect the making of international law. The article concludes that certain rules in the Manuals are marked by NATO influence and overlook the practice of other states engaged in cyber operations. Therefore, the Manuals disregard the generality of state practice, which should be the decisive factor in the formation of customary international law. As far as “political activism” may be involved, the article argues that the role of legal scholars as assistants to the cognition of international law could be compromised.
