- Citizen Sensing(also: Citizen Sensor, Participatory Sensing)
- A data collection approach in which members of the public use mobile devices or other tools to gather and report information about their environment, contributing to collective datasets that can inform decision-making. In accessibility contexts, citizen sensing enables people to…
- Community-sourcing(also: Community Sourcing, Community-contributed Data)
- A data collection approach where members of a specific community contribute information based on their direct experience and local knowledge, as distinct from general crowdsourcing which draws on anonymous, unrelated workers. In accessibility contexts, community-sourcing…
- Crowdsourced accessibility data(also: Crowdsourced validation, Accessibility crowdsourcing)
- The collection, verification, or enrichment of accessibility-related geographic or environmental information through the coordinated efforts of many distributed contributors, often via web-based platforms. Examples include validating automated crosswalk detections, mapping…
- Crowdsourcing(also: Crowd-Sourced Data, Community Reporting)
- A method of collecting data, information, or contributions from a large number of people, typically via the internet, rather than relying on a single authoritative source. In accessibility contexts, crowdsourcing is used to gather information about the accessibility of physical…
- Crowdsourcing
- The practice of gathering information, data, or contributions from a large group of distributed participants, typically via the internet. In accessibility, crowdsourcing platforms like Wheelmap and AccessTogether allow users to rate and report the accessibility of physical…
- Lifelogging(also: Life Logging, Digital Lifelogging)
- Lifelogging is the practice of automatically and continuously capturing data about a person's daily life using sensors, cameras, GPS, and other digital tools, typically worn or carried by the individual. In the context of accessibility, lifelogging data can be used to build…
- Passive Accessibility Sensing(also: Automatic Barrier Detection, Breadcrumb Sensing)
- A data collection approach that uses smartphone sensors (GPS, accelerometers, gyroscopes) to automatically detect potential accessibility barriers in the physical environment without requiring active user input. By analysing patterns in pedestrian movement data — such as…
- Personally Identifying Information(also: PII, Personal Data, Personally Identifiable Information)
- Any data that can be used to identify a specific individual, including names, addresses, photographs, financial details, and biometric data. In accessibility contexts, PII is a significant concern when disabled users contribute data for AI training, as they may inadvertently…
- Repository Mining(also: Software Repository Mining, Mining Software Repositories)
- A research methodology that involves extracting and analysing data from software repositories such as version control systems, bug trackers, code-sharing platforms, and Q&A sites like Stack Overflow. In accessibility research, repository mining has been used to assess whether…
- UAspeech Database(also: UAspeech, UA-Speech, Universal Access Speech)
- The UAspeech Database is a standardized corpus of dysarthric speech recordings created for research in accessible speech technology. It contains isolated word recordings from speakers with cerebral palsy exhibiting varying degrees of dysarthria, along with matched control…
- Virtual audit(also: Remote audit, Virtual streetscape audit, GSV audit)
- A method of assessing the physical environment for accessibility features and barriers using street-level imagery such as Google Street View, rather than conducting in-person site visits. Virtual audits allow researchers and practitioners to evaluate conditions like sidewalk…
