Human–computer interaction is a difficult endeavor with glorious rewards.
Designing interactive computer systems to be effective, efficient, easy, and enjoyable to use is important, so that people and society may realize the benefits of computation based devices. The subtle weave of constraints and their trade-offs – human, machine, algorithmic, task, social, aesthetic, and economic – generates the difficulty.

The reward is the creation of digital libraries where scholars can find and turn the pages of virtual medieval manuscripts thousands of miles away; medical instruments that allow a surgical team to conceptualize, locate, and monitor a complex neurosurgical operation; virtual worlds for entertainment and social interaction, responsive and efficient government services, from online license renewal to the analysis of parliamentary testimony; or smart telephones that know where they are and understand limited speech. Interaction designers create interaction in virtual worlds and embed interaction in physical worlds.

Human–computer interaction is a specialty in many fields, and is therefore multidisciplinary, but it has an intrinsic relationship as a subfield to computer science. Most interactive computing systems are for some human purpose and interact with humans in human contexts.
The notion that computer science is the study of algorithms has virtue as an attempt to bring foundational rigor, but can lead to ignoring constraints foundational to the design of successful interactive computer systems.
A lesson repeatedly learned in engineering is that a major source of failure is the narrow optimization of a design that does not take sufficient account of contextual factors factors. Human users and their contexts are major components of the design problem that cannot be wished away simply because they are complex to address.
In fact, that largest part of program code in most interactive systems deals with user interaction. Inadequate attention to users and task context not only leads to bad user interfaces, it puts entire systems at risk.
