Abstract: Design is the process of changing the status quo into something more desirable. Whether written or visual, if you have ever imagined the reaction of others and thought of a way to better communicate your intentions, you have experienced design. During this course, we clarify the contours of the act of design and learn the perspectives that we should be aware of as creators.

Abstract: The first step in design is to find the "right problem." We need to set goals such as what problems to address, what to resolve, and what to provide. In this course, you learn the process of organizing design requirements using worksheets and creating a standardized statement (Point of View: PoV statement) that answers these questions.

Abstract: Using this material, students learn how to explore the ideal form of digital products and determine the direction of expression. Expressions that meet people's needs are accompanied by functions and styles that suit their purposes. Here, we focus on users' experience with using digital products to achieve their goals; users learn how to define the functions and styles that are appropriate for their purposes.

Abstract: A lot of content is shared on the Internet, all of which are resources designed and published by others. Some are available for use, and some are not. During this course, students learn to understand the culture of creating and sharing digital expressions and learn perspectives for the appropriate use of materials and work shared by creators.

Abstract: Digital images are edited using two methods: image editing for creative purposes and image processing for research purposes. Although both have different purposes, they share the same essential approach of using the information in digital images without destroying it. In this course, you learn about the concept of making the most of information in digital images.

Abstract: In this material, we focus on the output of digital images and learn the differences in color modes between web and print media and points addressing how to output images at the optimal image resolution and image size for the usage scenario.
