...What is user interface design? User interface design or user interface engineering is the design of computers, appliances, machines, mobile communication devices, software applications, and websites with the focus on the user's experience and interaction. The goal of user interface design is to make the user's interaction as simple and efficient as possible, in terms of accomplishing user goals—what is often called user-centered design. Good user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Graphic design may be utilized to support its usability. The design process must balance technical functionality and visual elements (e.g., mental model) to create a system that is not only operational but also usable and adaptable to changing user needs. A user interface is the system by which people (users) interact with a machine. The user interface includes hardware (physical) and software (logical) components. User interfaces exist for various systems, and provide a means of Input, which allows the users to manipulate a system, and/or Output, which allows the system to indicate the effects of the users' manipulation. Generally, the goal of human-machine interaction engineering is to produce a user interface which makes it easy, efficient, and enjoyable to operate a machine in the way which produces the desired result. This generally means that the operator needs to provide minimal input to achieve the desired output, and also...

...Graphical User Interface Systems An Object Oriented Approach to the Design of Graphical User Interface Systems Nowadays, the usage of personal computers, mobile devices and internet among the general population, so the importance of easy to learn user interfaces has risen in recent years. The development of Graphical Interface Systems becomes important. These systems will make easy to user activities and communication of particular systems. The first and main feature of User Interface System is that manages the communication between user and application. So in the process of developing these systems, the object oriented programming features and techniques will make the design characteristics of interface systems like interactivity, flexibility and usability. Applying object-oriented methodologies to UI design can help to achieve this goal. To develop user interfaces, first identify the task to particular program function translation. It also involves identifying the object, problem space and associated functions, objects and attributes for the system. The main purpose of using object oriented approach in designing user interfaces because object programming allows for reusability,modularity and data privatization. modern graphical user interfaces are object-oriented; the user first accesses the object of interest and then modifies it by operating upon it. There are several reasons for going with an object-oriented interface approach for graphical user interfaces. One...

...User Interface A User Interface (UI) refers to the component of a computer program through which humans and machines exchange data and instructions in order to complete a task (User Interfaces). The data and instructions can be exchanged through a growing number of mediums such as text or graphical stimuli. Computer scientists go to great lengths to design and implement UIs, as they are imperative to the efficacy of the program they create. Without a working UI the computer and user would not be able to communicate with one another, severely limiting the ability of both. For instance, consider how difficult it would be to make a phone call if your phone did not provide you with a contact list or dialing pad. You would still be able to call, but it would take a much deeper level of knowledge to accomplish one of the phone’s most basic functions TYPES OF UI A UI will generally fall into one of 3 categories: command line, menu driven, and graphical 1. Command Line The oldest and least common UI is the command line interface. The command line interface is comprised solely of text. This type UI will accept input almost exclusively through the keyboard and requires the user to be familiar with the commands it accepts since no implicit direction is given. For example, Figure 1 shows a command line UI of a grade calculating program. There is no information given to the user other than the text on screen. Command line UIs are the most resource efficient of the three types of UI...

This was largely due to technical and hardware limitations. The poor interface design required a specific skill set for users and limited the mass appeal of computers. Modern interfaces are much more user friendly. Theo Mandel wrote about the five (5) golden rules of interface design. Read Mandel’s article located at http://www.theomandel.com/docs/Mandel-GoldenRules.pdf. Write a four to five (4-5) page paper in which you: 1. Describe three (3) interfaces you interact with on a daily basis. 2. Analyze each interface you identified in Question one (1) and assess how it adheres to Mandel’s five (5) golden rules. 3. Suggest two (2) changes for each interface to achieve a more user-friendly design and justify your suggestion. 4. Provide three (3) screen shots for each interface. Note: These screen shots should be labeled and appear in the appendix of the case study. These pages are not included in the page requirement for the assignment. 5.

...special person to do this kind of job and even though it is stressful, that special person thrives in this kind of work and are very good at managing it. For a successful project management, there are four areas that must be controlled and they are: 1. Assigning tasks to team members after organizing each individual into a team. 2. Closely monitoring and controlling the progress of the project. 3. Communication monitoring for the project. 4. Keeping track of all the open activities in the lifetime of the project. Systems design is the structuring the components and organizing the process of the system so that the new system can be programmed. The components are composed of the network, software, application architecture, system interfaces, user interfaces, the system appthat were built during the analysis. The outputs are the models or diagrams that describes the architecture of the system and detailed logic within the various components of the programming. Traditional Approach to Design The traditional approach to systems design is the data flow diagram which is enhanced by the addition of system boundary in which the designer sketches the system boundary to show the overall system. A structured design includes a system flowchart which show the movement of data among programs, manual processing steps, and files providing an overall view of the entire system. System flowcharts describes the interaction between layers of a multilayered system. Module pseudocode describes...

...The development of this application is being expanded more and more every day. How is iOS used? iOS (previously iPhone OS originally released June 29, 2007) includes a user interface that is based on the concept of direct manipulation. Direct manipulation, which uses multi-touch gestures, has interface control elements which consist of sliders, switches, and buttons. The interface elements consist of sliders, switches, and buttons, which includes gestures such as swipe, tap, pinch, and reverse pinch. The features of iOS include a home screen, folders, notification center, and much more. There are 40 million users who have interpreted this mobile application into their everyday lives. The home screen, also known as “SpringBoard”, displays different application icons and a dock where users can pin frequently used apps. This screen appears whenever the user unlocks the device. Folders on iOS have developed since the introduction with iOS 4. Folders can hold up to nine applications, which can be named to the users liking for different categories. The notification center is a system notification management which features notifications delivered in small banners that appear over the mobile application’s status bar. Improvement for Users The mobile application has not only dramatically changed how users communicate with...

...CIS 301 9:00 – 1:00 12/13/2014 Mobile App. Abstract: Mobile application development is the process where application software is developed for mobile devices like pda’s, tablets or mobile phones. As part of the development process, Mobile User Interface (UI) Design is also an essential in the creation of mobile apps. Mobile UI considers constraints & contexts, screen, input and mobility as outlines for design. The user is often the focus of interaction with their device, and the interface entails components of both hardware and software. User input allows for the users to manipulate a system, and device's output allows the system to indicate the effects of the users' manipulation. Mobile UI design constraints include limited attention and form factors, such as a mobile device's screen size for a user's hand(s). Mobile UI contexts signal cues from user activity, such as location and scheduling that can be shown from user interactions within a mobile application. Overall, mobile UI design's goal is primarily for an understandable, user-friendly interface. The UI of mobile apps should: consider users' limited attention, minimize keystrokes, and be task-oriented with a minimum set of functions. This functionality is supported by Mobile enterprise application platforms or Integrated development environments (IDEs). Mobile UIs, or front-ends, rely on mobile back-ends to support access to enterprise systems. The mobile back-end facilitates data routing, security, authentication...

...use of smart space space. Invisibility. Localised scalability. Masking uneven conditioning. • Adaptive behaviour arises due to a significant mismatch between supply and demand for resources. – Often in low level systems, e.g. bandwidth, memory. • As a mobile user moves, services and resources may become available or disappear. • Mismatch may occur even when the user is static static. • The system has to handle the variation in a way that minimises inconvenience to users and does not abruptly interfere with the task the user is trying to accomplish. WRES3405 (3) 3 WRES3405 (3) 4 • Other reasons for a mismatch: – The availability of compute servers or data-staging server is location-dependent and affects techniques such as cyber foraging. – In case of mobile code, low-level resources and interactive resources may vary widely between the source and destination systems. As time elapses, the resource level may change, for example, residual power on a laptop is depleted as battery drains. • The mismatch cannot be ignored as it will result in unsatisfactory user experience. • Adaptation is important not only as users move resource-rich to resource-poor environment but also in the other direction. – E a user should not b d i d of b tt quality E.g. h ld t be deprived f better lit video or speedier...
