    Interaction Design Studio - 711 Instructor: Patrick Thornton Email: [email protected] Thursday 6-8:45 pm Location: Pac 1815 - Clarice Smith Performing Arts Center Course Description Interaction design is the process of defining products and the broad services built around them. When interacting with systems, people build expectations and mental models of how things work. They learn what they can and cannot achieve. This course is about how to design for interactions that will resonate with your audiences: How the features and functions of a product get translated into something people find usable, useful, and desirable. Through a series of lectures, discussions, in-class design practice, and projects, students will explore the role of interaction designers. Students will learn how to prototype interactive products, systems, and services, and how to defend their work through the cycle of brainstorming and shared critique. This is a studio class, focusing on production processes that are required to develop public-facing work. The studio is important both as a working space and a space for collaborative reflection. Studio practice also describes a working method. As such, the INST711 classroom will focus on two activities: ● Externalization: You will put your ideas and conceptualizations into tangible materials. ● Critique: You will both give and receive constructive feedback on your own work and the work of other students in class. Student Learning Outcomes On the successful completion of this course, students will be able to: ● Explain basic concepts, techniques, and knowledge of interaction design. ● Critically discuss common methods in the interaction design process ● Use visual thinking and communication techniques to develop design concepts ● Build prototypes at varying levels of fidelity and can evaluate them using appropriate methods ● Develop critiquing skills to analyze interaction design artifacts and concept design.

    Principles of Interaction Design – LMC 6313 Syllabus Course Number: LMC 6313 Location: Skiles 346 Times: T/Th – 3:00p-3:50p F (lab) – 11:15a-2:00p Instructor: Dr. Anne Sullivan Instructor Email: [email protected] Office Hours: By Appointment (Mondays are the best bet) Office Location: TSRB 317C TA: Takeria Blunt TA Email: [email protected] Course Website: http://canvas.gatech.edu Course Description: What is interaction, what is design, where did these notions come from, and where are they going? Through the activities in this course, you will return to questions of what kind of designer you are and wish to be, what you believe in, and how that will extend to your research and practice. You will also develop your own critical take on the material in the class and sharpen your voice and arguments about your perspectives. Interaction design wasn’t invented from scratch as a singular, monolithic practice. It was born out of the intersection of a number of disciplines from within design and human-computer interaction, and also from art, media, architecture, politics, and philosophy, and beyond. There are many different definitions of what it is and where we fit into it, and no two people we meet in this class will likely have the same definition. And that’s the way it should be. Through my suggestions and yours, we will also turn to design questions in digital culture, film, tv, fiction, gaming, music, art and beyond as we together frame our understandings. As you read, The syllabus, dates, times, assignments, and details are subject to change by instructor notification through Canvas or email.

  • How Interaction Designers Use Tools to Manage Ideas Preprint
    How Interaction Designers Use Tools to Manage Ideas NANNA INIE, Aarhus University PETER DALSGAARD, Aarhus University This paper presents a grounded theory-analysis based on a qualitative study of professional interaction designers (n=20) with a focus on how they use tools to manage design ideas. Idea management can be understood as a subcategory of the field Personal Information Management, which includes the activities around the capture, organization, retrieval, and use of information. Idea management pertains then to the management and use of ideas as part of creative activities. The paper identifies tool-supported idea management strategies and needs of professional interaction designers, and discusses the context and consequences of these strategies. Based on our analysis, we identify a conceptual framework of ten strategies which are supported by tools: saving, externalizing, advancing, exploring, archiving, clustering, extracting, browsing, verifying, and collaborating. Finally, we discuss how this framework can be used to characterize and analyze existing and novel idea management tools. CCS Concepts: • Human-centered computing~User studies KEYWORDS Idea management; design ideas; design process; design tools; ideation ACM Reference format: 1 INTRODUCTION The fields of HCI and interaction design are well-known for studying impacts of novel interfaces and tools, and perhaps less known for studying the impact of tools that are already used in professional practice (Smith et al. 2009; Pedersen at al. 2018; Dalsgaard 2017). In the words of Stolterman, this ofen leads to research outcomes that are difficult to apply in practice, because the research is based on an inadequate understanding of how design happens in professional setings (Stolterman 2008).

  • Toward Unified Models in User-Centered and Object-Oriented
    CHAPTER 9 Toward Unified Models in User-Centered and Object-Oriented Design William Hudson Abstract Many members of the HCI community view user-centered design, with its focus on users and their tasks, as essential to the construction of usable user inter- faces. However, UCD and object-oriented design continue to develop along separate paths, with very little common ground and substantially different activ- ities and notations. The Unified Modeling Language (UML) has become the de facto language of object-oriented development, and an informal method has evolved around it. While parts of the UML notation have been embraced in user-centered methods, such as those in this volume, there has been no con- certed effort to adapt user-centered design techniques to UML and vice versa. This chapter explores many of the issues involved in bringing user-centered design and UML closer together. It presents a survey of user-centered tech- niques employed by usability professionals, provides an overview of a number of commercially based user-centered methods, and discusses the application of UML notation to user-centered design. Also, since the informal UML method is use case driven and many user-centered design methods rely on scenarios, a unifying approach to use cases and scenarios is included. 9.1 Introduction 9.1.1 Why Bring User-Centered Design to UML? A recent survey of software methods and techniques [Wieringa 1998] found that at least 19 object-oriented methods had been published in book form since 1988, and many more had been published in conference and journal papers. This situation led to a great 313 314 | CHAPTER 9 Toward Unified Models in User-Centered and Object-Oriented Design deal of division in the object-oriented community and caused numerous problems for anyone considering a move toward object technology.

  • Interaction Design
    Interaction Design Do you want to design products that are easy to use? Through this course you’ll develop an understanding of the patterns and principles that govern interaction design. You’ll become familiar with a framework for assessing the success of interaction design, you’ll learn to structure the design of products around the goals of users, and you’ll learn to sketch and wireframe your design ideas. OVER FOUR WEEKS, WE WILL COVER Introduction Interaction design is a major component of the user experience. It incorporates information architecture and usability to define how a product will behave. Projects: Business Goals, Competitive Analysis, Context of use Scenarios Usability To create products that are easy to use, designers obey a set of usability guidelines. These rules of thumb are good points of reference for making decisions, and for communicating and justifying design decisions to others. Project: Usability Competitive Analysis Intro to Sketching Sketching is a fast and easy way for designers to get their ideas out and discuss them collaboratively with team mates. Project: Sketching Exercise Information Architecture Information Architecture is the structural design of an interface that allows a user to access the right content at the optimal time so that she can navigate the product most effectively. Projects: Card Sorting, Sitemap User Flows User flows are the paths that a user takes through a product in order to complete her tasks. Project: User Flows Wireframes Once a designer hashes out the overall structure and navigation patterns of a product, she draws up the product’s blueprints, or wireframes.
