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 331 Software Design & Implementation University of Washington Spring 2022 This course aims to improve students' software development skills, focusing on building correct, scalable, and easy-to-understand software. It relies on a solid understanding of Java and the concepts covered in CSE 143. Students will learn about software design principles, modern programming languages, and software tools. It covers software testing, type systems, design patterns, and more. The aim of this course is to help students write programs of higher quality and increased complexity. This requires creating software that is correct, easy to change, easy to understand, and easy to scale. The course covers principled approaches to achieving each of these. The aim of this course is to help students write programs of higher quality and increased complexity. This requires creating software that is (1) correct, (2) easy to change, (3) easy to understand, and (4) easy to scale. We will study principled approaches to achieving these four goals.

After completing this course successfully students should be able to:

- Successfully build medium-scale software projects in principled ways
- Understand the role of specifications and abstractions and how to verify that an implementation is correct, including effective testing and verification strategies and the use of formal reasoning
- Analyze a software development problem and be able to design effective program structures to solve it, including appropriate modularity, separation of abstraction and implementation concerns, use of standard design patterns to solve recurring design problems, and use of standard libraries
- Use modern programming languages effectively, including understanding type systems, objects and classes, modularity, notions of identity and equality, and proper use of exceptions and assertions
- Use and learn new contemporary software tools, including integrated development environments, test frameworks, debuggers, version control, and documentation processing tools

In this class, we will use Java and associated tools like IntelliJ, JUnit, JavaDoc, and git, but the goal is to understand the underlying ideas and concepts that are generally applicable to software construction. The only formal prerequisite is CSE 143. We will very much rely on a thorough understanding of the concepts from CSE 143 as well as Java programming skills. We will go much further and you will be challenged to approach software development much differently than you have in CSE 143 or other courses. ### Texts

The required text for the course is the following:

- Effective Java by Joshua Bloch, 3rd ed., Addison-Wesley, 2018.

Contains a great deal of distilled wisdom about Java best practices, technical details, and style issues.

There will be assigned readings from this book during the quarter, and there will be questions on the exams about those readings.

Besides the required text, the following books may be helpful to you:

- The Pragmatic Programmer by Andrew Hunt and David Thomas, 20th anniversary (2nd) edition, Addison-Wesley, 2020.

Contains a great deal of distilled wisdom about software construction and the craft of programming, including many things that those who read the book later in their careers wish they had learned early on.

- Program Development in Java by Barbara Liskov and John Guttag, 1st ed, Addison Wesley, 2000.

The content of this well-written book closely mirrors much of the content of the course. The only downside is that it was written 17 years ago, so it is out-of-date with regard to some of key parts of the Java language and libraries. Nonetheless, it is a good place to look for another presentation of the material covered in class, if you can ignore those parts.

- Core Java Vol. I - Fundamentals by Cay Horstmann, 10th ed, Prentice-Hall, 2016; 11th ed, 2018.

This is a good general reference for the Java language and basic libraries. While technical documentation for these things is available on the web, the discussions in a book like this one are usually easier to follow and typically include advice not found in the formal documentation. Either recent edition will cover what we need for CSE 331.

CS 347 — Human-Computer Interaction: Foundations and Frontiers Stanford University Spring 2021 CS 347 is an advanced HCI course that surveys foundational and cutting-edge HCI research. Students participate in discussions, read relevant papers, and undertake a research project aimed for submission to a top-tier HCI venue. The course assumes previous experience with HCI, particularly for CS or SymSys students. This course is an advanced survey of HCI research. We cover foundations and frontiers: seminal work on interactive systems, and recent advances. Core topics include interaction, social computing, and design; breadth topics include AI+HCI, media tools, programming tools, and accessibility.

For undergraduates or masters students in CS or SymSys, having taken CS147 or CS247 is a prerequisite. Topics include ubiquitous computing, social computing, design tools+methods, AI+HCI, programming user interfaces, collaboration, and accessibility.

We read two papers per class. You will submit paper commentaries by 11:30am before each class, to prepare for our discussion.

Once during the quarter, you will help us lead the discussion on that lecture's readings. Read all student commentaries before class, create a summary, and prepare a meta-commentary on main themes. Peer assess all student commentaries.

In this course, you and two partners will complete a research project with the goal of submitting it as a poster or late-breaking work to a top-tier HCI venue.

For undergraduates or masters students in CS or SymSys, having taken CS147 or CS247 is a prerequisite. All graduate and PhD students from other departments are welcome. We expect attendance and active participation during lecture and discussion. This is a 4-unit course. For undergraduates or masters students in CS or SymSys, CS147 or CS247 is a prerequisite. All graduate and PhD students from other departments are welcome. Graduate students with a unit cap may enroll for 3 units; the workload is the same.
