- Data Minimization
- A privacy principle requiring that organizations collect, process, and retain only the minimum amount of personal data necessary to accomplish a specific purpose. For assistive technology users, data …
- Data Mining (Knowledge Discovery, KDD, Knowledge Discovery in Databases)
- Data mining is the computational process of discovering patterns, rules, and relationships in large datasets, drawing on techniques from statistics, machine learning, and database systems. Common task…
- Data Physicalization (Physical Data Visualization)
- The practice of representing data through physical, tangible objects rather than on-screen visualizations. Data physicalizations encode information in the shape, texture, size, weight, or other physic…
- Data Protection (Data Privacy)
- The practices, policies, and legal frameworks governing how personal information is collected, stored, processed, and shared by organizations. For assistive technology companies, data protection is es…
- Data Protection Impact Assessment (DPIA, Privacy Impact Assessment, PIA)
- A process required under GDPR Article 35 for assessing and mitigating risks to individuals' rights and freedoms before undertaking high-risk data processing. DPIAs are mandatory when processing is "li…
- Data Representativeness (Dataset Representativeness, Demographic Representativeness)
- The degree to which a dataset reflects the diversity of the population it is intended to serve, particularly across demographic dimensions such as age, gender, race, ethnicity, disability, and socioec…
- Data Sharing (Open Data, Data Dissemination)
- The practice of making research data available to other researchers or the public for reuse, replication, and further analysis. In accessibility research, data sharing presents unique tensions: datase…
- Data Sonification (Auditory Data Display, Sonified Data Visualization)
- The systematic mapping of data values to non-speech audio parameters such as pitch, volume, rhythm, timbre, or spatial location to make datasets perceivable through hearing. Data sonification is a key…
- Data Sovereignty
- The principle that data about a community — its people, territories, practices, or bodies — should be subject to the laws, governance, and collective authority of that community rather than of the out…
- Data Stewardship (Dataset Stewardship, Data Governance)
- The responsible management of data throughout its lifecycle, including decisions about collection, storage, access, sharing, and disposal. In accessibility research, participatory data stewardship inv…
- Data Structure
- A way of organizing and storing data in a computer so that it can be accessed and modified efficiently. Common introductory data structures include arrays, linked lists, stacks, queues, trees (such as…
- Data Table (Genuine Table)
- An HTML table element used to present structured, tabular information where data cells have a logical relationship to header cells. Accessible data tables require proper semantic markup including th e…
- Data Transparency (Data Processing Transparency)
- The practice of clearly communicating to users what data is collected, how it is processed, where processing occurs (on-device vs. cloud), how data is stored, and who has access to it. In accessibilit…
- Data Visualization (Data Viz, Information Visualization)
- The graphical representation of data and information using visual elements such as charts, graphs, maps, and diagrams. While data visualization is a powerful tool for communicating patterns and insigh…
- Data Visualization Accessibility (Accessible Data Visualization, Chart Accessibility, Visualization Accessibility)
- The practice of designing charts, graphs, diagrams, and other visual data representations so they are perceivable, operable, and understandable by people with disabilities, particularly those who are …
- Data sonification (Auditory graph, Audio chart)
- The representation of data values through non-speech audio, typically by mapping numerical values to auditory parameters such as pitch, volume, duration, or timbre. Data sonification makes charts and …
- Data visualization accessibility (Chart accessibility, Accessible data visualizations, Graph accessibility)
- The practice of making charts, graphs, maps, dashboards, and other visual representations of data perceivable and understandable by people with disabilities, particularly screen-reader users and peopl…
- Data-based Synthesis (Corpus-based Synthesis, Unit Selection Synthesis)
- A speech synthesis technique that generates speech by selecting and concatenating segments from a large database of prerecorded human speech, rather than using rules to generate acoustic waveforms fro…
- Data-to-Text (Data-to-Text Generation, Data-to-Text NLG)
- A subfield of natural language generation (NLG) that automatically produces human-readable text from structured data, such as databases, spreadsheets, or sensor readings. Data-to-text systems analyze …
- DataGlove (Data Glove, Sensor Glove, Cyber Glove)
- A wearable input device fitted with sensors that captures hand shape, finger position, and hand orientation data in real time. Originally developed by VPL Research in the 1980s, DataGloves were used e…
