This study evaluates the architectural status of circular prototype mosques in Kuwait. The argument is that the once dominant and powerful image of mosques is now merely a repetitive reproduction through the prototype scheme. The study focuses on the circular prototype design, which has been constructed in many of Kuwait's recent residential areas. It evaluates qualitatively the worshipers' experiences of these mosques.

The research methodology is qualitative. The main question is how well the circular prototype mosques are received by worshipers and local communities. Various research methods were used, including walk-through survey and group interview with worshipers and semi-structured interview with key informants in Public Authority for Housing Welfare and Ministry of Awqaf and Islamic Affairs. Purposive sampling was chosen to select for key informants. Time-location sampling was selected for worshipers' group interview.

Circular prototype presents several weaknesses. The community did not receive the circular design well as it deviates from the traditional and modern rectangular mosque design prevalent in Kuwait. This research highlights the importance of considering traditional design principles, community preferences and functional requirements while designing a mosque. It also emphasizes the need for an extensive evaluation of prototype designs to identify potential weaknesses before proceeding with the final design.

It is recommended that future mosque design projects in Kuwait consider traditional design principles; community preferences; and financial, functional and sustainability requirements. In addition, the findings of this study can be used to inform future mosque design projects in Kuwait and to ensure that they are functional, cost-effective and well received by the community.

This research provides an informative and comprehensive analysis of Kuwait's prototype mosque designs from the 1950s to the present day. It focuses on the current circular prototype, critically examining its advantages and disadvantages. This research is the first to evaluate the history and design improvements over the years. As such, this research offers invaluable information to those interested in Kuwait's religious architecture and cultural history.

Excess consumption of apparel is driven by the apparel industry to offer more styles at lower prices in shorter time and the consumers’ desire to change fashion. The purpose of this paper is to apply adaptable design in apparel as a sustainable design solution for excess consumption problem.

Guided by sustainable apparel design model C2CAD, two adaptable apparel prototypes for female college students were designed and developed. Focus group discussion and wear test were conducted with female college students to evaluate users’ acceptance, fit, comfort, and adaptability of the two prototypes.

Both prototypes were comfortable to wear by users with different sizes, indicating the users could wear the garment when she changed size. The adaptations and conversions were easily and enjoyably figured out by the users. The users would keep and use the adaptable apparel for a long time. The users would also buy fewer apparel if they were to own the adaptable apparel. Adaptable apparel would increase apparel utilization, eliminate the need to purchase unnecessary additional amount of clothing, and reduce excess consumption.

This research provided a pilot study on adaptable apparel design as an innovative approach to help solve excessive consumption problem. The adaptable garment prototypes would allow the fashion-forward female college student to easily change the function, fit, and style of the environmentally friendly garments.

This paper aims to argue about the involvement of additive technologies (ATs) in the prototyping issues of designing. More precisely, it reviews the literature contributions focused on the different perspectives of prototyping activities for design purposes, searching for both available knowledge and research needs concerning the correct exploitation of ATs.

A two-step literature review has been performed. In the first step, general information has been retrieved about prototyping issues related to design. In the second step, the literature searches were focused on retrieving more detailed information about ATs, concerning each of the main issues identified in the previous step. Extracted information has been analyzed and discussed for understanding the actual coverage of the arguments and for identifying possible research needs.

Four generally valid prototyping issues have been identified in the first step of the literature review. For each of them, available information and current lacks have been identified and discussed about the involvement of AT, allowing to extract six different research hints for future works.

This is the first literature review concerning AT-focused contributions that cover the complex and inter-disciplinary issues characterizing prototyping activities in design contexts.

This paper describes the development process of a mobile Voice User Interface (VUI) for Korean users with dysarthria with currently available speech recognition technology by conducting systematic user needs analysis and applying usability testing feedback to prototype system designs.

Four usability surveys are conducted for the development of the prototype system. According to the two surveys on user needs and user experiences with existing VUI systems at the stage of the prototype design, the target platforms, and target applications are determined. Furthermore, a set of basic words is selected by the prospective users, which enables the system to be not only custom designed for dysarthric speakers but also individualized for each user. Reflecting the requests relating to general usage of the VUI and the UI design preference of users through evaluation of the initial prototype, we develop the final prototype, which is an individualized voice keyboard for mobile devices based on an isolated word recognition engine with word prediction.

The results of this paper show that target user participation in system development is effective for improving usability and satisfaction of the system, as the system is developed considering various ideas and feedback obtained in each development stage from different prospective users.

We have developed an automatic speech recognition-based mobile VUI system not only custom designed for dysarthric speakers but also individualized for each user, focussing on the usability aspect through four usability surveys. This voice keyboard system has the potential to be an assistive and alternative input method for people with speech impairment, including mild to moderate dysarthria, and people with physical disabilities.

To illustrate the benefits of using the empirical similitude method when creating scale models with rapid prototyping processes, particularly in the context of evolutionary product design.

Apply the empirical similitude method in two experimental examples. Utilize rapid prototyping processes to create scale models. Both examples are based on the context of evolutionary product design. For one example, evaluate accuracy of empirical similitude results as compared to traditional similitude.

The first experimental example showed improved accuracy in the empirical similitude results as compared with traditional similitude. The second experimental example illustrated an effective approach for applying the empirical similitude method to a realistic product evolution.

Limited to two experimental examples. Examples involve a single prototyping process (selective laser sintering). Does not cover limitations of the empirical similitude method.

The approach provides for an effective way of utilizing rapid prototypes to predict the functional behavior of an evolutionary product. Rapid prototypes are readily available, but are rarely used in evaluating product function, due to limitations in part sizes and material properties.

This paper provides a practical way of utilizing rapid prototypes to predict the functional behavior of a product through scale models. It also illustrates the proposed method with two experimental examples.

The paper reflects on the development of a medical product using rapid prototyping technologies and customer interaction through a quality function deployment (QFD) approach to speed up the process, and to result in customer satisfaction. The purpose of the specific medical product was to develop a device for fixing an Endo‐tracheal (ET) tube in a patient during anaesthesia, as it is common for an ET tube to move and/or become dislodged due to various extraneous reasons. If the tube deviates from the correct position it can cause one or both lungs to collapse, which can be fatal. The paper reviews how the anaesthetist's idea, which was to develop a product that could hold an ET tube in place in a more secure manner than is possible with current technologies, was brought to fruition through customer interaction.

Using an action‐research approach, the design evolved through series of design concepts, which through customer interaction contributed to a total optimized design. Virtual and physical prototypes, together with silicone mouldings were used as part of the customer interaction.

As with any new product, some functional parts were needed to conduct tests, which in turn would help to prove the product, and hence, the design. Traditionally this meant the manufacturing of a hard tool and proving of the design through trial and error. Hard tooling allows for some small changes to be made, but if the changes are radical a new tool will have to be designed and manufactured.

Following a developmental approach through the application of various types/stages of prototyping (such as virtual prototypes), revolutionised this process by simplifying and accelerating the development iteration process – it also developed a new version/paradigm of QFD.

Opposed to traditional forms of QFD where customer inputs are gathered through questionnaires, this case study proved that functional models provide an efficient client‐feedback, through constant involvement in the development process, as well as evaluation of the systematic progress.

The case study shows that experts in other disciplines can become involved in the product development process through the availability of functional prototypes, and builds on previous work to introduce a concept of customer interaction with functional prototypes.

Many transportation companies struggle to effectively utilize the information provided by tracking technology for performing operational control. The research as presented in this paper aims to identify the problems underlying the inability to utilize tracking technology within this context. Moreover, this paper aims to contribute to solving these problems by proposing a set of design principles based on the concept of intelligent products.

The study as described in this paper adopts a design science research methodology consisting of three phases. First, a case study in a transportation company has been performed to identify the problems faced when utilizing tracking technology. Second, to overcome these problems, a set of design principles has been formulated. Finally, a prototype system based on the design principles has been developed and subjected to experimental and observational evaluation.

This paper identifies the problems associated with the utilization of tracking technology for the control of transport operations. Moreover, the proposed design principles support the development of information systems which overcome the identified problems and thereby enhance the utilization of tracking technology in a transportation context.

The commonly held perception that tracking technology will improve the ability to perform operational control does not unequivocally stand up to empirical scrutiny. While it is widely demonstrated that tracking technology is able to accurately capture the detailed operational information, it remains a fundamental challenge to transform this abundance of information into accurate and timely control decisions. This research provides a valuable contribution with respect to tackling this challenge, by identifying problems and providing solutions related to the utilization of readily available tracking technology.

An exact pattern prototype is a prerequisite for female girdle pattern-making. The purpose of this paper is to develop new ways to make girdle pattern prototypes based on 3D technology.

This paper presented two novel methods for creating girdle pattern prototypes. The first one was the girdle's parametric foundation pattern developing method based on 3D geometric modeling. In this method, considering the different characteristics of a female's lower body shape, several models were created to define the relationship between the female's lower body shape and the pattern, such as a side-waist curvature model, an interior-posterior waist-warping model, a buttocks' parametric model and an abdomen parametric model. Then, parameters of drawing the prototype were abstracted to facilitate transforming the 3D geometric model into the 2D pattern. Another method was implemented by 3D virtual modeling and unwrapping. The whole process included surface division, surface reconstruction and surface unwrapping.

The prototypes created by these two methods were tested using the 3D virtual trying-on examination. Trial tests showed that the patterns can be dressed in the right positions on the virtual model with little pressure. This means that the proportions and shapes of the pattern are correct. The prototypes obtained through the methods proposed in this paper have good effects and high precision. Both methods can be used for making the girdle's foundation pattern.

Two pragmatic approaches of girdle's prototype building have been put forward. The parametric prototype designing method has changed the unconstrained state of free modeling. The pattern structure can be controlled by parameter constraints. In the other method, with 3D scanning and surface modeling technology, personalized girdle's pattern is generated, and the segmentation lines of the girdle can be designed flexibly according to the requirements. These findings also can be used in other tight garments' prototype making.
