Computer graphics studies methods for creating and manipulating digital visual content with computers. In the past decade, the computer graphics field has seen tremendous advances in both hardware and software technologies. As a result, computer graphics technologies have helped advance many other areas such as entertainment, scientific visualization, training and simulation, computer-aided design and engineering, and architecture design. Human-computer interaction (HCI) is the study of interaction between users and computers. The field of HCI is closely related to many other fields, including psychology, design, computer graphics, operating systems, information security, and artificial intelligence. HCI studies also include consumer electronic devices that enjoy pervasive use in our daily lives.
