Redesign the User Interface of the Purwakarta Disdukcapil Mobile Application Using Kansei Engineering

The function and usability of a mobile application are the main reasons for making the application. In addition, the User Interface (UI) design factor is also an important consideration in making a mobile application. Good UI design is the main attraction for the application to use. There are many ways to make a good UI design. Kansei Engineering (KE) is one of the methods that can be used in the UI design process. Since the creation of the Mobile Disdukcapil application, there has never been a study on the application's design interface. This research aims to make recommendations on design elements desired by users. The KE method can detect the user's feelings towards an interface. So that the KE method will produce a UI design for the Disdukcapil mobile application that is liked by the user. The methodology used refers to the Kansei Engineering Type I methodology. This research uses Kansei Words to represent the emotional factors of the user when viewing a product specimen. Kansei Word used as many as 10 words related to the UI display on the mobile application. The mobile application specimens used were 5 specimens, which were taken from various similar applications. This study involved 80 participants to fill out the questionnaire. The results of the questionnaire were processed using multivariate statistical analysis, namely Cronbach's Alpha, Coefficient Correlation Analysis (CCA), Principal Component Analysis (PCA), Factor Analysis (FA), and Partial Least Square (PLS). The results of this study are in the form of recommendations for UI design elements based on the most dominant emotional factors. Based on the results of data processing, the dominant emotional factors are "Colorful" and "Simple".

Método do diamante duplo para o design de um aplicativo: Move in para a saúde e bem-estar

Este artigo apresenta o conceito de um aplicativo em realidade aumentada para dispositivo móvel, desenvolvido com o objetivo de apoiar a realização de atividades físicas. O que se pretende é estimular a realização de exercícios físicos para melhoria da qualidade de vida e diminuição do sedentarismo entre a população ativa, prevenindo o aparecimento de doenças não contagiosas. O processo de desenvolvimento está no uso de métodos e ferramentas de UX e UI Design. As etapas de Imersão, Definição, Ideação e Prototipação da Metodologia do Diamante Duplo, bem como as ferramentas utilizadas em cada uma delas, foram fundamentais para a compreensão e aprofundamento da importância das necessidades dos usuários no projeto, bem como na determinação das funções e requisitos de uso de um aplicativo, e direcionaram os parâmetros estéticos identificados como fundamentais para melhor interação sistema x usuário.

ACCU3RATE: A mobile health application rating scale based on user reviews

Background Over the last decade, mobile health applications (mHealth App) have evolved exponentially to assess and support our health and well-being. Objective This paper presents an Artificial Intelligence (AI)-enabled mHealth app rating tool, called ACCU3RATE, which takes multidimensional measures such as user star rating, user review and features declared by the developer to generate the rating of an app. However, currently, there is very little conceptual understanding on how user reviews affect app rating from a multi-dimensional perspective. This study applies AI-based text mining technique to develop more comprehensive understanding of user feedback based on several important factors, determining the mHealth app ratings. Method Based on the literature, six variables were identified that influence the mHealth app rating scale. These factors are user star rating, user text review, user interface (UI) design, functionality, security and privacy, and clinical approval. Natural Language Toolkit package is used for interpreting text and to identify the App users’ sentiment. Additional considerations were accessibility, protection and privacy, UI design for people living with physical disability. Moreover, the details of clinical approval, if exists, were taken from the developer’s statement. Finally, we fused all the inputs using fuzzy logic to calculate the new app rating score. Results and conclusions ACCU3RATE concentrates on heart related Apps found in the play store and App gallery. The findings indicate the efficacy of the proposed method as opposed to the current device scale. This study has implications for both App developers and consumers who are using mHealth Apps to monitor and track their health. The performance evaluation shows that the proposed mHealth scale has shown excellent reliability as well as internal consistency of the scale, and high inter-rater reliability index. It has also been noticed that the fuzzy based rating scale, as in ACCU3RATE, matches more closely to the rating performed by experts.

The Best Practice of Teach Computer Science Students to Use Paper Prototyping

The importance of understanding the repercussions of effective user interface (UI) design is critical for future Computer Science (CS) professionals, given the ubiquity of interfaces on computer devices. Through a paper prototyping activity, this article explains how to teach rapidly and successfully CS students about "fit," a Human-Computer Interaction (HCI) concept. Despite its simplicity, the concept of "fit" can be difficult to grasp without much practice. In practice, designing "fit" into UIs can be prohibitively expensive because workable prototypes are generally beyond the technical capabilities of students. As a result, we illustrate how to use paper prototyping to demonstrate "fit" in a hands-on class exercise based on active learning concepts. To guide students through the process of "fit" in UI design, we provide extensive step-by-step directions for planning, setting up, and presenting the exercise. Students will be better equipped to apply both theoretical and practical applications of "fit" in UI design and execution as a result of this assignment; this exercise can be used in any course that covers user interface design, such as concepts of human-computer interaction, systems analysis and design, software engineering, and project management.

Data-Driven Approaches to User Interface Design: A Case Study

The most common reason for software product failure is misunderstanding user needs. Analysing and validating user needs before developing a product can allow to prevent such failures. This paper investigates several data-driven techniques for user research and product design through prototyping, customer validation, and usability testing. The authors implemented a case study software product using the proposed techniques, and analyses how the application of UX/UI research techniques affected the development process. The case study results indicate that preliminary UX/UI research before the development reduces the cost of product changes. Moreover, the paper proposes a set of metrics for testing the effectiveness of UX/UI design.
