- Profound and Multiple Learning Disabilities (PMLD, Profound Intellectual and Multiple Disabilities, PIMD)
- Profound and multiple learning disabilities (PMLD) refers to a combination of profound intellectual disability with additional physical, sensory, or health impairments that together create extremely c…
- Programming Accessibility (Accessible Programming, Accessible IDE)
- The practice of making software development tools, environments, and workflows usable by programmers with disabilities. Programming presents unique accessibility challenges beyond general computer use…
- Programming by Demonstration (PBD, Record and Replay, Macro Recording)
- A technique for creating automated sequences of actions by recording a user performing the task manually, rather than requiring the user to write code or scripts. The system observes the user's intera…
- Programming by Example (PBE, Programming by Demonstration)
- A technique in end-user programming where a system infers a generalizable program from concrete examples provided by the user, rather than requiring the user to write code directly. In accessibility c…
- Progress Bar (Progress Indicator)
- A UI element that visually communicates the proportion of a task, process, or timeline that has been completed. In media players it indicates playback position; in forms and wizards it signals complet…
- Progress Tracking (Progress Indication, Progress Visualization)
- The use of visual or auditory indicators to show how far a user has advanced through a task, document, or process. In cognitive accessibility, progress tracking serves multiple functions: it provides …
- Progressive Disability (Degenerative Condition, Progressive Condition)
- A disability or condition that worsens over time, requiring adaptive strategies and technologies that can evolve with changing abilities. Progressive disabilities such as dementia, multiple sclerosis,…
- Progressive Disclosure (Staged Disclosure, Layered Interface)
- An interaction design pattern that initially presents only the most essential options or information, revealing additional complexity progressively as users need or request it. Progressive disclosure …
- Progressive Enhancement
- A web design strategy that starts with a baseline of essential content and functionality that works in any browser or with any internet connection, then layers on enhanced features for users with more…

- Prompt Chaining (Chained Prompting, Sequential Prompting)
- A technique for interacting with large language models where multiple prompts are issued in sequence, with each prompt building on the output of the previous one to achieve a more refined or accurate …
- Prompt Contradiction
- A type of large language model failure in which the system disregards explicit instructions or constraints given in the user prompt, producing output that contradicts what was asked. For example, an A…
- Prompt Engineering (Prompt Design, Prompt Crafting)
- The practice of designing and structuring input prompts to guide large language models (LLMs) toward producing more accurate, relevant, and useful outputs. In accessibility contexts, prompt engineerin…
- Prompt Injection (Indirect Prompt Injection, Prompt Engineering Attack)
- A technique — originally an LLM security concern — in which carefully crafted instructions embedded in a user prompt or referenced content override the model's intended behaviour, constraints, or safe…
- Prompt engineering (Prompt design, Prompt crafting)
- The practice of designing and iteratively refining natural language inputs to large language models to elicit more accurate, relevant, or useful responses. In accessibility contexts, prompt engineerin…
- Prompting System (Prompting Device, Task Prompting Technology)
- An assistive technology that provides stepwise guidance through text, images, audio, or video instructions to help individuals complete multi-step tasks such as cooking, personal hygiene, or workplace…
