Interaction design, often abbreviated as IxD, is "the practice of designing interactive digital products, environments, systems, and services." While interaction design has an interest in form, its main area of focus rests on behavior. Rather than analyzing how things are, interaction design synthesizes and imagines things as they could be. This element of interaction design is what characterizes IxD as a design field, as opposed to a science or engineering field.
Ben Shneiderman is an American computer scientist, a Distinguished University Professor in the University of Maryland Department of Computer Science, which is part of the University of Maryland College of Computer, Mathematical, and Natural Sciences at the University of Maryland, College Park, and the founding director (1983-2000) of the University of Maryland Human-Computer Interaction Lab. He conducted fundamental research in the field of human–computer interaction, developing new ideas, methods, and tools such as the direct manipulation interface, and his eight rules of design.
User experience design defines the experience a user would go through when interacting with a company, its services, and its products.User experience design is a User Centered Design approach because it considers the user's experience when using a product or platform. Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), and encompasses all aspects and stages of a customer's experience and interaction with a company.
Contextual design (CD) is a user-centered design process developed by Hugh Beyer and Karen Holtzblatt. It incorporates ethnographic methods for gathering data relevant to the product via field studies, rationalizing workflows, and designing human–computer interfaces. In practice, this means that researchers aggregate data from customers in the field where people are living and applying these findings into a final product. Contextual design can be seen as an alternative to engineering and feature driven models of creating new systems.
The Special Interest Group on Computer–Human Interaction (SIGCHI) is one of the Association for Computing Machinery's special interest groups which is focused on human–computer interactions (HCI).
Sonic interaction design is the study and exploitation of sound as one of the principal channels conveying information, meaning, and aesthetic/emotional qualities in interactive contexts. Sonic interaction design is at the intersection of interaction design and sound and music computing. If interaction design is about designing objects people interact with, and such interactions are facilitated by computational means, in sonic interaction design, sound is mediating interaction either as a display of processes or as an input medium.
User experience evaluation (UXE) or user experience assessment (UXA) refers to a collection of methods, skills and tools utilized to uncover how a person perceives a system before, during and after interacting with it. It is non-trivial to assess user experience since user experience is subjective, context-dependent and dynamic over time. For a UXA study to be successful, the researcher has to select the right dimensions, constructs, and methods and target the research for the specific area of interest such as game, transportation, mobile, etc.
Marilyn Mantei Tremaine is an American computer scientist. She is an expert in human–computer interaction and considered a pioneer of the field.
Victoria Bellotti is a Senior CI researcher in the Member Experience Team at Netflix. Previously, she was a user experience manager for growth at Lyft and a research fellow at the Palo Alto Research Center. She is known for her work in the area of personal information management and task management, but from 2010 to 2018 she began researching context-aware peer-to-peer transaction partner matching and motivations for using peer-to-peer marketplaces which led to her joining Lyft. Victoria also serves as an adjunct professor in the Jack Baskin School of Engineering at University of California Santa Cruz, on the editorial board of the Personal and Ubiquitous Computing and as an associate editor for the International Journal of HCI. She is a researcher in the Human–computer interaction community. In 2013 she was awarded membership of the ACM SIGCHI Academy for her contributions to the field and professional community of human computer interaction.
Catherine Plaisant is a French/American Research Scientist Emerita at the University of Maryland, College Park and assistant director of research of the University of Maryland Human–Computer Interaction Lab.
Feminist HCI is a subfield of human-computer interaction (HCI) that applies feminist theory, critical theory and philosophy to social topics in HCI, including scientific objectivity, ethical values, data collection, data interpretation, reflexivity, and unintended consequences of HCI software. The term was originally used in 2010 by Shaowen Bardzell, and although the concept and original publication are widely cited, as of 2020 Bardzell's proposed frameworks have been rarely used since.
