The Need for User Interface Design

User Interface Design is often associated with software interface and is frequently referred to as Human-Computer Interface or HCI. However, User Interface Design must be considered wherever users interact with controls or displays. The application of interface design is pervasive, including products such as: a simple watch, a DVD player, an aircraft cockpit, a software program, etc. In many cases, good technology is not readily accepted because the product is not easy to use or efficient to use. A product's usability, acceptance, and marketability are often dependent on the user feeling that it is easy to learn and use. User Interface Design increases the intuitiveness, efficiency, and comfort level with a product, which translates into product acceptance and use. You need both good technology and usability for a successful product launch.
