Objective: Learn about Direct Manipulation The characteristics of direct manipulation include visibility of objects, incremental action, rapid feedback, reversibility, exploration, syntactic correctness of all actions and replacing language with actions. For each characteristic consider and discuss an example task performed with modern GUIs. Contrast the task with the same task as performed in a command-line environment such as Unix, Linux bash, Windows Command line or DOS.

Early computer systems relied on command line interfaces to perform all actions. Today, the majority of systems use direct manipulation rather than a command line interface. The goal of designing a direct manipulation interface is to make use of the system intuitive to the end user. One industry that has been extremely successful designing intuitive direct manipulation inputs is the video game industry. Most game players are able to learn controls as they play a game and then apply the same controls to similar games. Rarely do they need to read a user manual. Write a four to five (4-5) page paper in which you: Describe the three (3) principles of direct manipulation and give examples as to how they are used in video game controls. Analyze video game-type interfaces and discuss three (3) reasons why video game-type interfaces would not be effective for real-world applications. Describe at least three (3) advantages of direct manipulation versus…
As part of a software team creating a smart phone's user interface, you'll need to have a conversation about the best approach.Is it hard to design computer interfaces? Explain in detail the kinds of activities that are performed.After a list item or object has been shown, the interface should p
Design a javafx GUI for Tasks Management. The Task data is: id, title, status, added by, creation date. Do the following: Add Task manually and from a file. View Tasks. Find All Tasks titles that added by “Ali" sorted by id. Find the top four tasks sorted by creation date. Find all tasks that start with the letter 'a' and have exactly seven letters (ignore letter 'a' case). Find who added the largest number of tasks. Find the number of tasks that are closed and open. Count the tasks that added by "Sami".

Use of interfaces has many benefits. The creation of objects of a certain class seems to be the simplest solution.
Create a Java application using the GUI components that incorporates event handlings. Create a simple java as example, , school management system that accepts user to key in data or simple calculation then display the result.
This next program is a little simpler, but it still illustrates some very critical program structures. It also illustrates an idea that is still used commonly, even if the mechanism has evolved with modern tools and alternative languages. We are referring to a menu-based help system. Modern help systems and menus are often represented using an integrated user environment; however, the core concepts behind the help system remain largely unchanged from this assignment. Create an interactive help system for Java programming. The system will incorporate a menu system that interacts with the user, and the appropriate help topic will be displayed, based on an input selection. This program is going to require some research on your part, as well as some programming in Java. Specifically, you will need to find definitions for the Java terms included in your help system. You can read the textbook or scour the Internet for the definitions. They should be no more than a few sentences each; nothing…
