A motivational theory in psychology proposed by Abraham Maslow that organises human needs into a hierarchical pyramid, from basic physiological needs at the base through safety, social belonging, este…
Metacommunication (Designer-User Metacommunication)
In semiotic engineering, metacommunication refers to the overarching communication that takes place between a software designer and a user through the medium of the computer interface. The interface a…
PICTIVE (Plastic Interface for Collaborative Technology Initiatives through Video Exploration)
PICTIVE is a participatory paper-prototyping technique introduced by Michael Muller at CHI 1991, in which end users and designers jointly build low-fidelity interface prototypes using pre-cut paper UI…
Participatory Design with Proxies (PDwP, Proxy Design)
A variation of participatory design in which people who are familiar with target users or who closely resemble them are included in the design process as proxy participants. Proxies — such as parents,…
Persona (User Persona, Design Persona)
A fictional character created to represent a type of user who might interact with a product, service, or website. Personas are grounded in research data and typically include details such as name, age…
Point of Infrastructuring (PoI)
A concept from Pipek and Wulf's infrastructuring theory naming the moment at which users become aware of the technology they depend on - typically when it breaks, behaves unexpectedly, or no longer su…
Reflection-in-Action (Reflection-on-Action)
A concept from Donald Schön's theory of reflective practice (The Reflective Practitioner, 1983) describing how skilled practitioners adjust their approach in the moment, based on tacit knowledge and i…
Requirements Gathering (Requirements Elicitation, Needs Assessment)
The process of collecting and documenting the needs, constraints, and expectations of users and stakeholders to inform the design of a technology system or product. In accessibility and assistive tech…
Research Probe (Design Research Probe, Technology Probe)
A purpose-built, partially functional artefact — often a software prototype, sensor, or interactive installation — deployed in a study not primarily to deliver a finished product but to provoke reflec…
Research-through-Design (RtD)
A research methodology, articulated by Zimmerman, Forlizzi, and Evenson (2007), in which the act of designing artefacts is itself the mode of inquiry. Knowledge is produced through iterative cycles of…
Tactile Rendering
The process of converting visual or spatial information into a tactile format that can be perceived through touch by blind or visually impaired users. Tactile rendering involves decisions about how to…
Tailorability (Tailorable systems)
A design property, central to infrastructuring theory, that allows users to configure, extend, or repurpose a system after deployment to fit their local use context. Tailorability goes beyond 'customi…
Universal Access Reference Model (UARM)
A conceptual framework for understanding and addressing the full range of user needs in information and communication technology. The Universal Access Reference Model provides a structured approach to…
Usability Engineering
A systematic, structured approach to designing and evaluating user interfaces that applies engineering principles to usability. Usability engineering involves defining measurable usability goals, cond…
User Empowerment (Design for User Empowerment)
A design philosophy that prioritizes giving users, particularly people with disabilities, the agency and tools to solve their own problems, customize their experiences, and participate as active creat…
User Sensitive Inclusive Design (USID)
A design methodology proposed as an alternative to User Centred Design for populations with highly diverse and dynamically changing needs, particularly older people. User Sensitive Inclusive Design re…
User-Centred Design (UCD, User-Centered Design, Human-Centred Design)
An iterative design methodology that places the needs, characteristics, and limitations of end users at the centre of each stage of the design process. In accessibility, user-centred design involves p…
User-System Model (User-System Interaction Model)
A conceptual model that describes the relationship between a user and the technology system they interact with, taking into account the user's abilities, preferences, and needs alongside the system's …
Wizard of Oz Study (WOZ Study, Wizard of Oz Method)
A research method in which participants interact with what they believe is an automated system, but which is actually operated in whole or in part by a human "wizard" hidden from view. The method is u…
