User interface

CSE 340 Interaction Programming University of Washington Spring 2022 This course focuses on the design and programming of interactive systems, exploring various programming paradigms, event handling, and accessibility. It requires prior knowledge of Java and familiarity with data structures. This course helps to develop user-friendly interfaces and study existing interfaces. Although the platform used is Android, it's not strictly an Android programming course. Interactive technology is changing society. Some of today’s interfaces are used by a billion people at a time. Almost everything we create is created for people to use, through user interfaces. We will learn about interactive systems, including programming paradigms and design of event handling, layout, undo, accessibility and context awareness. ## Why should I take this class?

Interfaces are an important part of our daily lives and many of them are created as a connection from a human to a machine. Even a new machine learning algorithm or a database system requires some human connection in order for those systems to work.

User interfaces are incredibly important, but interactive user interaction requires a different programming paradigm than you may have learned before. In this you will learn how to:

- write an event-driven program which reacts to user input and displays output using abstractions in a structured and maintainable way. These abstractions generally transfer to almost any other user interface toolkit.
- think about the design and implementation of novel interaction techniques such as voice based interfaces or augmented reality, in order to enrich the user experience.
- build inclusive and accessible user interfaces.
- implement implement user-centered features, such as Undo, that following well studied design principles that are applicable in any user interface.
- critique and study existing user interfaces using light weight informal and formal methods.
- communicate your findings through comprehensive reports as well as reflections on your learning

The [Course Details](https://courses.cs.washington.edu/courses/cse340/22sp/course-details.html) page describes each of our course modules as well as other classes that complement the learning goals in CSE 340.
 The only official requirement for this class is that you have taken **CSE 142 and 143 or an equivalent class**, meaning you are comfortable programming in Java, and have some experience with data structures.

There are other skills that are required for the class that are not explicitly taught, which means you should **plan to spend extra time (either independently or in OH) learning and practicing those skills**. These include:

- working in an Integrated Development Environment (IDE) that is more complicated than JGrasp
- Using a version control systems (Git)
- Reading and understanding library and toolkit documentation
- Reading and understanding a larger starter code base
- Reflecting on and explaining the coding work you have done
- Reading through assignment specifications which are “more complicated and less detailed” than a typical Introduction to CS assignment specification.

Taking CSE 391 just before or concurrently with 340 can help, but our staff can also assist where needed.

The specific platform and language for this class are **Java on Android phones** (or simulators); using the IntelliJ IDE (Android Studio). While Google is switching over to Kotlin, there are good reasons to [start learning Android with Java first](https://dzone.com/articles/java-vs-kotlin-which-language-android-developer-sh).

Note that this class is designed for CSE majors, and other students who work regularly with information technology and are strong programmers. While we will consider applications from outside the major, other restrictions may limit space for such students. ### What should I expect as a student in this class?

This is an **interaction programming course** which will teach the abstractions that underly all user interfaces (see the [Course Details](https://courses.cs.washington.edu/courses/cse340/22sp/course-details.html) page for more information). To learn these concepts, we will cover a mix of theoretical aspects of HCI (such as how to predict the time it will take to click on a button, or why Undo is important to implement) and practical aspects of HCI (such as how to handle user interface events). What we will not cover is Android programming.

To re-iterate, *this is not an Android programming class and you will be expected to research Android programming yourself*. We will point you at the relevant of Android documentation but you must be willing to read through and explore this documentation on your own.

Taking any class is a commitment, and this one is no exeception. We want to make sure you get the most out of your experience. Below is some information about prerequisites and expectations.

CSE 452 Distributed Systems University of Washington Winter 2022 This senior-level course offers deep insights into the construction of distributed systems like client-server computing, web, cloud computing, and peer-to-peer systems. Major topics include remote procedure call, error management, and consistency of distributed state. Noted for its intellectually challenging and career-relevant approach. Distributed systems are central to many aspects of how computers are used, from web applications to e-commerce to content distribution. This senior-level course will cover abstractions and implementation techniques for the construction of distributed systems, including client-server computing, the web, cloud computing, peer-to-peer systems, and distributed storage systems. Topics will include remote procedure call, preventing and finding errors in distributed programs, maintaining consistency of distributed state, fault tolerance, high availability, and scaling.

Alumni of this course say that it is among the most intellectually challenging courses that they have taken at UW, and among the most relevant to their future careers. We will attempt to live up to that recommendation. We believe the best way to learn the material is to implement the ideas presented in the course, and so there is a substantial programming project.

The [calendar page](https://courses.cs.washington.edu/courses/cse452/22wi/schedule) provides a detailed topic list for the course, including readings, problem sets, and labs. In addition, we are using Gitlab, Ed, and Gradescope for various parts of the course.

CSE 154 Web Programming University of Washington Summer 2022 This course introduces the fundamental concepts of web programming and technologies required for web development. It covers the full spectrum of web development, from HTML, CSS, JavaScript to server-side technologies like Node.js, databases, and SQL. CSE 154 is an introduction to programming for the World Wide Web and the technologies that support it. The course is one part practical: you will learn how to use the tools and technologies to build websites. It's also one part theoretical: you'll learn how and why many of these technologies work. And it's one part creative: you'll get an opportunity to design and explore creative ways of building a website.
