Understanding people: extensions of human–computer interaction

Science and design are often seen as being at opposite ends of an academic discipline spectrum. Indeed, this is often the case. However, there are several fields that connect these two ends of the spectrum together. Human computer interaction (HCI) is one such field, being described as the bridge between science and design. HCI involves research into the design, development and use of computer technology that focuses on the interfaces between humans and technology. From the outset, usability – creating software that people will want to use, will be able to use and will find effective/satisfying to use – took a central role in HCI. In fact, there was a drive in the early days to create designs to ensure that people would not need to think too hard about the interface and how it worked. In other words, it needed to be easy to use. Since then, HCI has expanded and is now a multidisciplinary community encompassing a wide range of concepts that still include usability.
