Assessing the Quality of Mobile Graphical User Interfaces Using Multi-Objective Optimization
Noname manuscript No. (will be inserted by the editor) Assessing the Quality of Mobile Graphical User Interfaces using Multi-objective Optimization Makram Soui · Mabrouka Chouchane · Mohamed Wiem Mkaouer · Marouane Kessentini · Khaled Ghedira the date of receipt and acceptance should be inserted later Abstract Aesthetic defects are a violation of quality attributes that are symp-toms of bad interface design programming decisions. They lead to deteriorating the perceived usability of mobile user interfaces and negatively impact the Users eXperience (UX) with the mobile app. Most existing studies relied on a subjective evaluation of aesthetic defects depending on end-users feedback, which makes the manual evaluation of mobile user interfaces human-centric, time-consuming, and error-prone. Therefore, recent studies have dedicated their effort to focus on the definition of mathematical formulas that each targets a specific structural quality of the interface. As the UX is tightly dependent on the user profile, the combi-nation and calibration of quality attributes, formulas, and users characteristics, when defining a defect, is not straightforward. In this context, we propose a fully automated framework which combines literature quality attributes with the users profile to identify aesthetic defects of MUI. More precisely, we consider the mobile user interface evaluation as a multi-objective optimization problem where the goal is to maximize the number of detected violations while minimizing the detection complexity of detection rules and enhancing the interfaces overall quality in means M.

Using Microsoft Visual Studio to Create a Graphical User Interface ECE 480: Design Team 11
Using Microsoft Visual Studio to Create a Graphical User Interface ECE 480: Design Team 11 Application Note Joshua Folks April 3, 2015 Abstract: Software Application programming involves the concept of human-computer interaction and in this area of the program, a graphical user interface is very important. Visual widgets such as checkboxes and buttons are used to manipulate information to simulate interactions with the program. A well-designed GUI gives a flexible structure where the interface is independent from, but directly connected to the application functionality. This quality is directly proportional to the user friendliness of the application. This note will briefly explain how to properly create a Graphical User Interface (GUI) while ensuring that the user friendliness and the functionality of the application are maintained at a high standard. 1 | P a g e Table of Contents Abstract…………..…………………………………………………………………………………………………………………………1 Introduction….……………………………………………………………………………………………………………………………3 Operation….………………………………………………….……………………………………………………………………………3 Operation….………………………………………………….……………………………………………………………………………3 Visual Studio Methods.…..…………………………….……………………………………………………………………………4 Interface Types………….…..…………………………….……………………………………………………………………………6 Understanding Variables..…………………………….……………………………………………………………………………7 Final Forms…………………....…………………………….……………………………………………………………………………7 Conclusion.…………………....…………………………….……………………………………………………………………………8 2 | P a g e Key Words: Interface, GUI, IDE Introduction: Establishing a connection between -
How to Use the Graphical User Interface TCS Technical Bulletin
How to Use the Graphical User Interface TCS Technical Bulletin A. Create/Edit the Graphical Interface (Build Mode) Accessing the site using the Graphical Interface requires that you first build a layout (one or more layers/tabs depending on your site). This is done using the setup wizard to upload images/backgrounds and place controllers in appropriate locations on those images/backgrounds. When finished and saved, the User accesses the site using the Graphical Interface. 1. Click the “+” button to add a layer/tab for the site. (Skip to step 7 to edit an existing layer.) 2. Name the layer/tab by clicking in the field and entering the desired name. 3. Click the Choose File button to select the desired background image from your computer’s drive and click the Save button. 4. The Place View will open showing you the layer/tab title, a Save Positions button, the background image, and a bin of available controllers along the right-hand edge of the Graphical Interface which can be placed onto the layer/ tab. 5. Drag/drop controller icons from the icon bin to the desired location on the background image. Moving your mouse over each icon will show that controller’s name. The arrows at the top and bottom of scroll bar or the scroll bar itself allow you to scroll through the available controllers. NOTE: If you have placed controller icons too close to the icon bin and you would like to move them, you may need to scroll the available controllers up or down to clear the area around an icon to allow it to be dragged/dropped again. -
A Successor to the X Window System
Y: A Successor to the X Window System Mark Thomas <[email protected]> Project Supervisor: D. R¨uckert <[email protected]> Second Marker: E. Lupu <[email protected]> June 18, 2003 ii Abstract UNIX desktop environments are a mess. The proliferation of incompatible and inconsistent user interface toolkits is now the primary factor in the failure of enterprises to adopt UNIX as a desktop solution. This report documents the creation of a comprehensive, elegant framework for a complete windowing system, including a standardised graphical user interface toolkit. ‘Y’ addresses many of the problems associated with current systems, whilst keeping and improving on their best features. An initial implementation, which supports simple applications like a terminal emulator, a clock and a calculator, is provided. iii iv Acknowledgements Thanks to Daniel R¨uckert for supervising the project and for his help and advice regarding it.

The Three-Dimensional User Interface
32 The Three-Dimensional User Interface Hou Wenjun Beijing University of Posts and Telecommunications China 1. Introduction This chapter introduced the three-dimensional user interface (3D UI). With the emergence of Virtual Environment (VE), augmented reality, pervasive computing, and other "desktop disengage" technology, 3D UI is constantly exploiting an important area. However, for most users, the 3D UI based on desktop is still a part that can not be ignored. This chapter interprets what is 3D UI, the importance of 3D UI and analyses some 3D UI application. At the same time, according to human-computer interaction strategy and research methods and conclusions of WIMP, it focus on desktop 3D UI, sums up some design principles of 3D UI. From the principle of spatial perception of people, spatial cognition, this chapter explained the depth clues and other theoretical knowledge, and introduced Hierarchical Semantic model of “UE”, Scenario-based User Behavior Model and Screen Layout for Information Minimization which can instruct the design and development of 3D UI. This chapter focuses on basic elements of 3D Interaction Behavior: Manipulation, Navigation, and System Control. It described in 3D UI, how to use manipulate the virtual objects effectively by using Manipulation which is the most fundamental task, how to reduce the user's cognitive load and enhance the user's space knowledge in use of exploration technology by using navigation, and how to issue an order and how to request the system for the implementation of a specific function and how to change the system status or change the interactive pattern by using System Control. -
Toward General Purpose 3D User Interfaces: Extending Windowing Systems to Three Dimensions

However, these devices require custom integration with every application which wishes to use them, seriously limiting application support, and there is no established mechanism for mul- tiple applications to use the same 3D interface hardware simultaneously. This thesis proposes that these problems can be solved in the same way that the same problems were solved for 2D interfaces: by abstracting the input hardware behind input prim- itives provided by the windowing system and compositing the output of applications within the windowing system before displaying it. -

Development and Analysis of a Window Manager Concept for Consolidated 3D Rendering on an Embedded Platform
Institute of Parallel and Distributed Systems University of Stuttgart Universitätsstraße 38 D–70569 Stuttgart Master’s Thesis Nr. 0202-0001 Development and Analysis of a Window Manager Concept for Consolidated 3D Rendering on an Embedded Platform Han Zhao Course of Study: INFOTECH Examiner: Prof. Dr. Kurt Rothermel Supervisor: Dipl.-Inf. Simon Gansel, Dipl.-Inf. Stephan Schnitzer Commenced: 19. Jan. 2015 Completed: 21. July 2015 CR-Classification: I.3.2, C.3, D.4.9 Abstract Nowadays with the information technology rapidly developing, an increasing number of 2D and 3D graphics are used in automotive displaying systems, to provide vehicle information, driving assistance, etc. With the demand of 3D models interacting with each other, an implementation should have a 3D compositing capability. However, traditional 2D compositing implementations are not capable of 3D models compositing tasks. In order to composite 3D graphics on embedded platform, the 3D compositing implementation is necessary. Therefore, a concept of window manager is developed aiming to composite 3D graphics with an optimized efficiency for embedded platform. Specially for automotive platforms, a virtualization is made to unify multiple Electronic Control Units (ECUs) into one single ECU platform. On this platform, a server and multiple clients are implemented with dedicated Virtual Machines (VMs). The server is in charge of rendering tasks requested from clients. Based on this, a 3D compositing concept is implemented. It handles efficiently the multiple 3D applications situation using a method of off-screen rendering. A server-side virtualization is also implemented by replacing certain client-side commands during commands forwarding. With this virtualization implementation, multiple applications run simultaneously with accessing single 3D GPU only. -
GUI Vs Command Line (CLI)
GUI vs Command Line (CLI) Windows vs Non Windows Based Two most popular ways to interact with a computer are the Command Line and the GUI (Graphical User Interface). Command line is a text only interface, while GUI is an Interface, composed of graphical symbols. Most of the times, all the general tasks performed using a GUI can be performed by a Command line and vice versa (although when it comes to advanced tasks Command line may be the only option). What is a GUI? GUI (pronounced gooey) is a type of interface that allows users to communicate with operating systems in the form of images/animations/audio as opposed to text. This interface presents the user with the information/actions available through graphical objects (like icons). Both mouse and keyboard can be used for the interaction. The user performs actions by directly manipulating graphical objects on the screen. What is a Command Line? Command Line (typically known as Command-line interface/interpreter or CLI) is a mechanism that allows interacting with the computer operating system by inputting (typing) commands. This is a text only interface, which only requires input from the keyboard (usually referred to as “entering a command”). Typically, Enter key is pressed at the end of a command, after which the computer will receive, parse and execute that command. The output of the command will be returned back to the terminal as text lines. Output may include a summary of the task and the actual result as well. To insert command in a batch mode, user can use a script file. -
