Android UI Layouts: Graphics Design Using the ViewGroup Class

Tokopedia is one of the companies in Indonesia that has a unicorn status. With a vision to build a platform that allows anyone to start and find anything and anywhere, Tokopedia also supports Micro, Small and Medium Enterprises (MSMEs) and individuals to develop their businesses through application. Even so, this does not guarantee that all Tokopedia users can really easily use the application. The baby boomer generation is a generation that faces more difficulties in processing new or complex information, thus affecting their learning about new technologies, including the user interface design of an application. The purpose of this study is to understand how the user interface elements are applied to the Tokopedia application and how the baby boomer affordance to the Tokopedia application user interface design. The method used is a case study with a qualitative approach. The results show that the user interface design elements of the Tokopedia application in the perception of baby boomer generation are always related to design elements, use of color, and layout. Some of these elements have been understood by the user's function. Nevertheless, there are some technical things, such as the use of free space, that users still don't understand. Thus, Tokopedia still has to make some improvements to the application's user interface design .

Social Media platforms are increasing user engagements with their attractive User Interfaces (UI) design playing a crucial role in maintaining user involvement. Use of Emotional Intelligence (EI) into the UI transforming user interaction and engagement pattern significantly. With an emphasis on how design decisions affect user behaviour, this study explores the nuanced function of EIUIs (Emotionally Inteligence User Interfaces) in the context of social media. It specifically draws attention to the dangers of manipulative techniques like "dark patterns"-purposeful interface strategies intended to influence users to take actions they might not have otherwise taken-as well as the possibility of constructive involvement. By investigating these practices, the paper hopes to clarify the wider ethical consequences of interface design as well as the duty of platforms and designers to promote transparency, autonomy, and confidence in digital interactions. This paper aims to contribute to the discourse on user interface design by providing a comprehensive understanding of EIUIs' potential and pitfalls in the context of social media interactions. Additionally, this study focusses on finding information of the pattern of Emotionally Intelligent User Interfaces (EIUI) design to enhance user engagements emotionally and tend to take decisions and the impact of the design pattern in user experience.

An optical brain-machine interface (O-BMI) system using calcium imaging has various advantages such as high resolution, a comprehensive view of large neural populations, abilities such as long-term stable recording, and applicability to freely behaving animals in neuroscience research. The present study developed an ergonomic user interface (UI) design, based on a use scenario for an O-BMI system that can be used for the acquisition and processing of calcium imaging in freely behaving rodents. The UI design was developed in three steps: (1) identification of design and function requirements of users, (2) establishment of a use scenario, and (3) development of a UI prototype. The UI design requirements were identified by a literature review, a benchmark of existing systems, and a focus group interview with five neuroscience researchers. Then, the use scenario was developed for tasks of data acquisition, feature extraction, and neural decoding for offline and online processing by considering the sequences of operations and needs of users. Lastly, a digital prototype incorporating an information architecture, graphic user interfaces, and simulated functions was fabricated. A usability test was conducted with five neuroscientists (work experience = 3.4 ± 1.1 years) and five ergonomic experts (work experience = 3.6 ± 2.7 years) to compare the digital prototypes with four existing systems (Miniscope, nVista, Mosaic, and Suite2p). The usability testing results showed that the ergonomic UI design was significantly preferred to the UI designs of the existing systems by reducing the task completion time by 10.1% to 70.2% on average, the scan path length by 14.4% to 88.7%, and perceived workload by 12.2% to 37.9%, increasing satisfaction by 11.3% to 74.3% in data acquisition and signal-extraction tasks. The present study demonstrates the significance of the user-centered design approach in the development of a system for neuroscience research. Further research is needed to validate the usability test results of the UI prototype as a corresponding real system is implemented.

Android-based devices have become devices for every student in communication activities and learning media, therefore the Introduction to Linguistics course requires learning media, so the alternative is to use an Android-based application. The purpose of this study was to analyze the emotional factor in designing the interface for Android-based Introductory Linguistics teaching materials with the Kansei Engineering approach; make recommendations for the interface design of Android-based Introduction to Linguistics teaching materials.

This paper proposes a method for user interface development where a model for analysis (Just-UI) and a model for design (DiaMODL) are conveniently combined into an integrated method. Just-UI currently supports automatically refining analysis models, through conceptual patterns to concrete user interface designs. Integrating a dialog modelling language (DiaMODL) into the method, will let the designers take part in the refinement process, hence gaining control and allowing a greater variety of designs. The method encourages the use of code generation for rapid prototyping of the UI. The ultimate objective is to provide a suitable software engineering and user interface design method with coverage to cross through requirements to final implementation of core application code and user interface.

There have been numerous studies done on the guidelines of user interface, but only a number of them have considered specific guidelines for the design of children’s interface. This paper is about a research on the specific guidelines for children, focusing on the criteria of graphic design. The objective of this research is to study on the guidelines of user interface design and to develop specific guidelines on children’s graphic design. The criteria of graphic design are the priority of this research since previous research have proven that graphic design is the main factor which contributes to the problem of usability of web application interfaces, in terms of the overall graphic layout not being in a hierarchical order, not taken into concern the availability of space, inappropriate margin, improper type and font size selection, and less concentration on the use of the colours. The research methodology makes use of the comparison of and the coordination to the guidelines on children’s interface and the specific guidelines on the graphic design of web application interfaces. The contribution of this research is the guidelines on the design of web application graphics which are specifically for children. DOI: http://dx.doi.org/10.11591/telkomnika.v11i6.2658

Cross-use pattern language: cross-cultural user interface development tool

<p>Mobile Tole Playing Games (RPGs) are now very popular in gaming market. Still, we have great constraint in hardware provided such as screen size and interaction speed. Adopting techniques such as auto play enables the game designers to weaken the burdens of porting RPG scales to mobile platform. However, the interface design in mobile platform becomes quite different from PC based platform. In this paper, we investigate how user interface functionalities are provided for popular mobile RPGs based on google play downloaded between the year of 2014 and 2016. We analyze the commonalities and the differences of recent successful mobile RPGs first and take a user survey with heuristics. In result, subjects who are 16 ~ 25 in age weakly accept current interface layout and control as over 70% positive rate in 4 point Likert scale test.</p>

In today’s automotive industry there is an increasing demand for VR technology, because it provides the possibility to switch from cost and time intensiv physical mock up’s (PMU) to digital mock up’s (DMU). Furthermore the visualization and examination of simulation results is a very important aspect during the whole development cycle. Therefore tools are needed, which enable the users to work with DMU’s, as well as simulation data sets in an efficient and intuitive way. In this paper we present the design of a VR user interface for evaluating simulation data sets. The design of the user interface is based on the basic interaction tasks (BIT’s), introduced by Foley et. al.. This allows to generalize the results presented herein and to apply them to other domains.KeywordsData ProbeInput DeviceMenu ItemDesign ReviewColor FigureThese keywords were added by machine and not by the authors.

According to International Data Corporation (IDC), Android accounted for 81% of all smartphone shipments in the third quarter of 2013. With the increase in smartphones, mobile application installs from Google Play have reached more than 48 billion app installs as revealed by Sundar Pichai, senior vice president, Chrome and Apps at Google I/O 2013. Thus, Android application development has become increasingly popular with the need of an effective software solution for application development and testing. While most Android applications are developed in Java, the Android framework is quite different fromm typical Java frameworks. Thus, while development or testing of Android applications, the user needs to be aware of all the terms and concepts specific to the Android framework such as activity, views and the Android SDK in general.

Over time, the practice of graphic design has been undergoing progressive changes so much so that various authorities have come up with various specifications. There are various types of graphic designs amongst which are web design, user interface and user experience design, advertising and marketing design, game design, motion graphics, cartoons and animations, illustrations and typography, and publication design to mention but a few. This topic extrapolates the nuances of a minimalist approach to modern graphic design and in this essay; the word “graphics” has been used as a generic term that encapsulates corporate designs of items such as news magazines, journals, annual reports, calendars, book cover designs and such like. The objective of this research is to bring to the fore and compartmentalize the various stages of the minimalist approach to creating a cutting-edge modest design. The research methodology employed for this study is studio-based and practice-led, the survey and quasi-ethnographic study with some touch of literature review. Discussion exclusively centered on the antecedents of minimalism and steps to be taken in achieving a catchy design using the simplest techniques possible while it was concluded that it is more advantageous to adopt the minimalist approach to graphic designs with reasons rightly highlighted and expatiated on.

This paper provides an overview of important software engineering research issues related to the development of applications that run on mobile devices. Among the topics are development processes, tools, user interface design, application portability, quality, and security.

Design Patterns (DPs) are acknowledged as powerful conceptual tools to improve design quality and to reduce time and cost of the development process by effect of the reuse of "good" design solutions. In many fields (e.g., software engineering, web engineering, interface design) patterns are widely used by practitioners and are also investigated from a research perspective. Still, they have been seldom explored in the arena of Recommender Systems (RSs). RSs provide suggestions ("recommendations") for items that are likely to be appropriate for the user profile, and are increasingly adopted in content-intensive multimedia applications to complement traditional forms of search in large information spaces. This paper explores RSs through the lens of User Interface (UI) Design Patterns. We have performed a systematic analysis of 54 recommendation-empowered content-intensive multimedia applications, in order to: (i) discover the occurrences of existing domain independent UI patterns; (ii) identify frequently adopted UI solutions that are not modelled by existing patterns, and define a set of new UI patterns, some of which are specific of the interfaces for recommendation features while others can be useful also in a broader context. The results of our inspection have been discussed with and evaluated by a team of experts, leading to a consolidated set of 14 new patterns that are reported in the paper. Reusing pattern-based design solutions instead of building new solutions from scratch enables novice and expert designers to build good UIs for Recommendation-empowered content intensive multimedia applications more effectively, and ultimately can improve the UX experience in this class of systems. From a broader perspective, our work can stimulate future research bridging Recommender Systems, Web Engineering and Interface Design by means of Design Patterns, and highlights new research directions also discussed in the paper.

Humans spend 90% of their lives inside buildings, but often the Heating, Ventilation, and Air Conditioning (HVAC) systems of commercial buildings do not properly maintain occupant comfort. Use of feedback through comfort voting applications has been shown to improve the quality of service, but the effects of application feedback and user interface design has not been investigated. In this work, we present several methods of feedback that use data presentation and environmental interaction in comfort voting applications. Through a 40 week user study of 61 University employees across 3 buildings, we show that feedback systems can be used to increase user satisfaction with thermal conditions from 33.9% to 93.3% and reduce energy consumption up to 18.99% compared to a system without voting. In addition, we find that by including a drifting control strategy, we find energy savings up to 37% can be realized without a significant reduction in satisfaction.
