Interaction Design (IxD): Interaction Design refers to the process of creating and optimizing the way users engage and interact with digital products or interfaces, such as websites, mobile apps, and software. The focus of IxD is on understanding how users engage with a product, making it more user-friendly, and improving the overall user experience. This is achieved through designing intuitive and efficient interfaces, incorporating essential elements like navigation, buttons, and feedback. Good interaction design aims to make the user's interaction with the product seamless and enjoyable, ultimately leading to increased user satisfaction and higher conversion rates.
