The core topics at the intersection of human-computer interaction (HCI) and US law -- privacy, accessibility, telecommunications, intellectual property, artificial intelligence (AI), dark patterns, human subjects research, and voting -- can be hard to understand without a deep foundation in both law and computing.Every member of the author team of this unique book brings expertise in both law and HCI to provide an in-depth yet understandable treatment of each topic area for professionals, researchers, and graduate students in computing and/or law. Two introductory chapters explaining the core concepts of HCI (for readers with a legal background) and U.S. law (for readers with an HCI background) are followed by in-depth discussions of each topic.
