A Collaborative and Interactive Surface Concept for Early Stages of New Product Development—A Multi-stage Expert Study

To come up with new ideas and innovations, product developers are faced with the challenge of finding a suitable way through a jungle of tools and methods, e.g., creativity tools, CAD software and project management applications. The goal of this paper is to develop a user interface concept for a supportive tool that integrates a variety of tools on an interactive surface to enable horizontal collaboration and interaction during creativity sessions in product development. Therefore, the user interface should not just support collaboration but also incorporate guidance to support product developers to find a suitable path through this jungle of tools and methods. To elicit requirements for such a supportive tool, an explorative multi-stage study design was chosen. In the first part expert workshops were conducted to create a design space. This space was further explored in a second phase, to derive relevant requirements. In the last phase, first visions of the supportive tool and possible design ideas were developed. The results of this study form a foundation to build a supportive tool for product developers that could pave the way to a new form of digital collaboration, provides a more holistic understanding of the development process and its activities and furthermore enhances the acceptance of creativity methods.
Proposal of a Firefly Algorithm with Three Types of Functionally Differentiated Fireflies

Firefly algorithm (Firefly Algorithm; FA) is one of the swarm intelligence algorithms. FA is known as the algorithm that is based on the flashing behavior of fireflies and their associated behavioral patterns. Specifically, FA associates the objective function with the light intensity of fireflies, and searches for the optimal solution based on the feature that fireflies are attracted to those with higher light intensity than themselves. In this way, we can find the optimal solution. However, since FA only uses the information of the other firefly with light intensity stronger than itself, it may not be able to find the optimal solution if the firefly with the highest light intensity falls into the local solution. On the other hand, while fireflies in nature are naturally distinguished into males and females, in general FA, all fireflies are defined as the same functional group with no gender and uniform behavioral patterns. Therefore, FA do not have the diversity of behaviors and may not be possible to properly solve problems due to uniform behavior patterns. In this study, we propose an algorithm that distinguishes the sexes of fireflies in FA and defines different behavioral patterns for female fireflies. By achieving diversity in the movements of fireflies, we aim to avoid the defined FA system falling into local solution and find the optimal solution. The proposed FA system is applied to the maximization problem of mathematical function, and the effectiveness of the system is verified by comparing it with existing FA systems in previous studies.
A Study on Skill Transfer Using Augmented Reality

Effective methods of skill transfer are required at the manufacturing site of heavy industry with high-mix, low-volume manufacturing. Several previous studies have shown that giving unskilled worker simultaneous experiences in the skilled worker’s visual sense from a first-person perspective and force sense is effective for the skill transfer. This paper proposes a method of skill transfer by creating holographic moving images of workpieces and tools from the skilled worker’s motion. In order to analyze the effectiveness of this method, a control experiment by the assembly work of Tetris Block was carried out as a preliminary experiment. By using the proposed method and movie instruction which has already been put to practical use, each experimental participant’s assembly work was observed and compared, and the difference of two methods was analyzed from the three viewpoints of the work procedure, work time, and body motion. As a result, the effectiveness of the proposed method was confirmed from three perspectives; the margins of the body motion can be provided by the movement of holograms, the movement of holograms can communicate the skilled worker’s detailed motion information, and the skill transfer is possible in the virtual space environment which is not affected by real space. The future task is to verify the findings of this study by applying proposed method to actual field works.

Assessment of income group based on features causing decision paralysis

According to Barry Schwartz, a psychology professor, "people do not make decisions based on what's the most important, but based on what's the easiest to evaluate." This directly opposes the thought of providing too many choices to consumers, which has been treated as a very common process to win the minds of consumers. But it has a side effect of making consumers confused. Searching for information, 'best deal' has become an 'obligation rather than opinion' which in long run results in stress, sub-optimal decisions (Mitchell and Papavassiliou, 1999). This is the scenario where decision paralysis originated. This current study aims to find the factors restricting the decision-making process of consumers while purchasing consumer durable as well as luxury items. Along with feature extraction, classification using random forest has been performed with 98.20% accuracy. This study provides a guideline for marketers to categorise consumers into 'higher' or 'lower' income groups based on decision paralysis features.
A ranking paired based artificial bee colony algorithm for data clustering

Data clustering aims to partition a dataset into k subsets according to a prespecified similarity measure. It is NP-hard, and has lots of real applications. This paper presents a ranking paired based artificial bee colony algorithm (RPABC) to solve data clustering. First, a chaotic map is employed to generate initial food sources. Second, in order to speed up the search, RPABC uses a ranking paired learning strategy to produce new positions. Finally, the best food source is utilised to guide the search in the onlooker bees' phase. Several datasets from the literature are used to test the RPABC. The computational results show that the proposed method is able to provide high quality clusters, and is more stable than the compared algorithms.

L1 in L2: Indonesian towards English in Public Speaking Class

Indonesian or Bahasa (L1) as a learner's first language is often used in English (L2) speaking lessons. This phenomenon often occurs even though teachers have informed them that using Indonesian during English-speaking skills classes is not permissible. Many reasons are suggested by experts why students use this first language. The most prominent reason is the student's lack of understanding of L2. However, this phenomenon still occurs in Public Speaking classes where students are already at the intermediate and advanced levels. In connection with this phenomenon, this study aims to find the main reasons students in the Public Speaking class use Indonesian in their English-speaking skills and what they think about using Indonesian in their English-speaking skills. A total of 50 students in two Public Speaking classes were observed and given questionnaires about their reasons and opinions for using Indonesian in speaking English skills. The results show that the highest reason students use L1 (Indonesian) in Public Speaking class is to process new and complex concepts. They argue that using Indonesian makes it easier for them to explain and understand the new concept.
