Modeling how different user groups perceive webpage aesthetics

UNIVERSAL ACCESS IN THE INFORMATION SOCIETY 2023年第4期22卷 1417-1424页

作者： Leiva, Luis A. Shiripour, Morteza Oulasvirta, Antti Univ Luxembourg Esch Sur Alzette Luxembourg Aalto Univ Espoo Finland

Aesthetics is a central consideration in user interface design. It is known to affect end-user behavior and perception, in particular the first impression of graphical user interfaces. However, what users perceive as pleasant or good design is highly subjective. We contribute a computational model that estimates the visual appeal of a given webpage for several common cohorts, or user groups, including gender, age, and education level. Our model, a convolutional neural network trained on 418 webpage screenshots having 771k aesthetic scores (in a 1-9 Likert scale) from 32k users, achieves high accuracy and is always less than 1 point off from ground-truth ratings. Designers can use our model to anticipate how people would rate their webpage, offer personalized designs according to the visual preferences of their users, and support rapid evaluations of webpage design prototypes for specific cohorts.

user interface description languages (UIDL) are high-level languages allowing to model user interfaces (UI). Their purpose is to ease the design of UIs. They are widely used, including to develop critical interactive systems. Nevertheless, the problem of verifying systems developed with UIDLs is barely addressed in the literature. The first step is to provide a formal semantics using an appropriate theory. We claim that the bigraphs theory is a good candidate theory. In this short paper, presenting a work in progress, we introduce the common features of UIDLs and show how bigraphs could be used to define UIDLs semantics and help with UI verification. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

学位级别：博士

Despite their increasing popularity and omnipresence in modern graphical interfaces, anima- tions are still largely under-comprehended. While prior research and practice provide useful insights about the merits and downsides of animation, it is still unclear what makes a good and effective animation that improves the usability and expressivity of graphical interfaces. The disparity of opinions about the value of animation is mainly due to the fact that most of previous studies have investigated the benefit of adding a particular animation to a particular interface, leaving a notable gap in the deep understanding of the many design aspects that influence the performance of animation. Prior research have also predominantly assessed the value of animation through a narrow empirical angle, which had left several facets of animation unveiled. This thesis contributes a first constructive step toward better understanding the vast design space of animation and mapping out the various merits of animation that can enrich user interfaces from different perspectives. We first provide a structured view of the roles and drawbacks of animation in user interfaces. We then present the theoretical fundamentals for animation in information visualization. We discuss the main challenges for designing and evaluating animation in dynamic visualizations. Through an empirical study, we investigate the meaning of the Common Fate Law, applied on animation trajectories, in dynamic visual- izations. We then introduce a design space that allows a holistic characterization of staged animation and propose an authoring tool to support the prototyping and exploration of staging in visualizations.

jCAB: Making Java Class Design Easier for Novice Programmers

jCAB: Making Java Class Design Easier for Novice Programmers

Frontiers in Education (FIE) Conference

This Research Full Paper introduces a tool called Java Class Auto Builder (jCAB) that helps students to design Java custom classes, helps them to understand the core concepts in the class design, and helps them to develop Object-Oriented (OO) ideas efficiently. When OO programming is introduced to students, its fundamental concepts are difficult for them to learn at first, and also impact them when they start to design their custom class templates. The existing UML (Unified Modeling Language) based tools could be served for educational purpose, but they are not suitable for novice Java students or programmers. Those tools generate class template code automatically from UML diagrams which must represent the class structures and functionalities clearly. That requires users to have a comprehensive view on the class structures. However, when they are first exposed to custom class design, novice programmers usually do not know what are necessary in the design and/or the relationships among classes if there are any. Therefore, it would be hard for them to develop UML diagrams which could represent class templates clearly. A tool that could help students in this stage is necessary. The jCAB tool introduced in this paper is designed for Java CS1 course, and is a good start for novice programmers to learn how to implement custom classes. The tool divides the custom class design procedure into several steps in order to show students what are necessary in the class design clearly and how to do them in detail. Its GUI (Graphic user Interface) interacts with students, directs them step by step, and generates code in each step automatically, so that students will be aware of the class structure, the design procedures, and how each piece of code is related with OO concept, and they will have better grasp on the OO fundamentals and the custom class design procedures.

Software developers use software products to design and develop new software products for others to use. Research has introduced a concept of developer experience inspired by the concept of user experience but appreciating also the special characteristics of software development context. It is unclear what the experiential components of developer experience are and how it can be measured. In this paper we address developer experience of Vaadin Designer, a graphical user interface designer tool in terms of user experience, intrinsic motivation, and flow state experience. We surveyed 18 developers using AttrakDiff, flow state scale, intrinsic motivation inventory and our own DEXI scale and compare those responses to developers' overall user experience assessment using Mann-Whitney U test. We found significant differences in motivational and flow state factors between groups who assessed the overall user experience either bad or good. Based on our results we discuss the factors that construe developer experience.

Interactive exploration of the executable linking process

Interactive exploration of the executable linking process

Roedunet International Conference (RoEduNet)

作者： Andrei Ciprian Aprodu Răzvan Deaconescu Computer Science and Engineering Department University POLITEHNICA of Bucharest Bucharest Romania

Students learn about the existence of the linking process, but few know and understand what it does. The theoretical explanation requires a good background in compilers and operating systems. It can be easier to explain with by example, showing every change of the process. With available tools not beginner friendly, ELF Detective aims to make the linking processes more tangible to beginners. ELF Detective uses binary executable files to thoroughly analyse and explain the linking phase in an educational way. This makes it a lot easier to understand it without having extensive technical background.

学位级别：master

A set top box is an embedded device, much like a computer with limited capabilities. Its main purpose is to decode a video signal and output it to a TV. The set top box market is constantly growing and to be competitive in it, a set top box has to be able to do more than only TV. One way to make an attractive product is to give it an appealing user interface. This thesis is a part of a larger work at the company to find new ways to create graphical user interfaces. Its goal is to investigate what SVG implementations that exits, which one that is most suitable for an integration attempt and then perform the *** SVG engines were investigated and one provided by the company was selected for integration. Three ways to integrate the SVG engine were identified. One of these alternatives was to extend the callback interface be- tween the engine and the underlying platform. Because of the good fit with the current architecture this alternative was chosen and implemented. As a part of this investigation a demo application suite of SVG content was also *** investigation resulted in a working integration of the chosen SVG engine on the platform. It has also showed that SVG is a suitable language to build graphical user interfaces on set top boxes

Our Web-based interactive game-playing-oriented college selection system acts as a smart advisor/mentor and helps students, parents, and teachers use an effective graphical user interface to efficiently search college information and to make good decisions at each stage of students' academic development. It is an expert agent with hierarchical fuzzy knowledge base using fuzzy logic. users are expected to be able to use this agent as a trusted, involved and smart counselor, who remembers their profile and their past history and advises them through their high school years. It gives them increasingly better and specific nuggets of advice as they make progress through their schools, and guides them toward a selected set of colleges to apply that optimizes their potential. At the heart of this system is an assessment tree, which uses bottom-up fuzzy calculations to generate possibility of admission in various sets of colleges. The primary output is a short list of colleges to apply containing five kinds of colleges (highly-selective down to non-selective) with possibilities of acceptance in each college according to fuzzy rules provided. It is also a smart tool to play self-guided "what if games to explore what specific action one should be taking to have maximum impact on the selection of colleges one can get in and on his/her chances of admission. It employs a natural interactive interview process for a user (i.e., a user can play a game with the agent to gradually find out rational solutions), and produces advisories at different stages.

Evolution of interactive graphical representations into a design language: a distributed cognition account

引用

INTERNATIONAL JOURNAL OF HUMAN-COMPUTER STUDIES 2002年第4期57卷 317-345页

作者： Giordano, D Univ Catania Dipartimento Ingn Informat & Telecomunicaz I-95125 Catania Italy

This study investigates the evolution of the graphical representations used to specify information systems in a community of novice designers supported by a shared design memory, adopting the paradigm of distributed cognition. The nature of the relationship between design notations, quality of design and communication is explicated by considering the interplay of actors, representations, design task and an evolving social and cultural context. An account is provided of how meaningful representational features are transmitted and transformed across generations of designers, and combined in a design language that improves design quality and accommodates varied communication needs and interactional constraints. Diffusion and creation of novel representational features start from a process of critical imitation steered by criteria of instrumental utility set by the individual design teams to address both their needs, concerning level of understanding and desired expressiveness of the design, and the socially regulated expectations about what is required in a good design. These tendencies result in an organizational phenomenon according to which the language of the community evolves by incorporating more sophisticated representational modes, i.e. patterns of features that are used in a socially clever way, in particular to reduce the cognitive load involved in interpretation, and to sustain interaction with the instructor during the exam. It is argued that the cognitive fit between the general characteristics of design task and the expressive modalities allowed by the medium used for the design specifications, plus the individual differences between the novice designers are key factors in sustaining the evolution of the language.

There is much more to designing usable GUI screens than making them look good. The way a screen looks should tell the user how to interact with it, and what behavior to expect. Screen design is about visual communication, the bridge between the look and the feel of the user interface. In this full day tutorial you will examine the principles of good screen design, including a detailed examination of screen layout, templates and metaphors. The tutorial provides a clear understanding of how to take advantage of user knowledge when creating screen designs that work. Examine layout techniques, including colour, fonts and symbols, and learn the principles of creating easy-to-use software and interactive new media productions. The tutorial is very much hands-on with exercises - you will put the skills you learn into practice. Learn valuable tips and techniques for the best ways to use icons, controls, text and graphics in user interfaces. © 1998. Copyright on this material is held by the author.
