- Mobility Assessment (Mobility Evaluation, Gait Assessment)
- A clinical evaluation that quantifies a person's movement capabilities, including walking pattern, balance, and motor performance. Mobility assessments are used to diagnose conditions like Parkinson's…
- Mobility Disability (Mobility Impairment, Physical Mobility Limitation)
- A disability that affects a person's ability to move freely, including walking, climbing stairs, maintaining balance, or using fine motor skills. Mobility disabilities may result from conditions such …
- Mobility Impairment (Mobility Disability, Physical Mobility Limitation)
- A condition that limits a person's ability to move freely and independently, affecting functions such as walking, climbing stairs, or maintaining balance. Mobility impairments can result from congenit…
- Mobility Impairment (Motor Impairment, Physical Disability)
- A disability that affects movement, ranging from conditions requiring wheelchair use to limited fine motor control affecting device interaction. Mobility impairments may result from conditions like pa…
- Mobility and Orientation Trainer (MOT, Orientation and Mobility Specialist, O&M Specialist, O&M Instructor, Habilitation Specialist)
- A qualified professional who teaches orientation and mobility (O&M) skills to blind and partially sighted people, enabling safe and independent travel. MOTs assess individual needs and deliver persona…
- Mobility-as-a-Service (MaaS, Transportation-as-a-Service)
- A transportation model that integrates various mobility services (public transit, ridesharing, bike-sharing, car rentals) into a single accessible platform, typically via a smartphone app. For people …
- Modal Dialog (Modal Window, Dialog Box)
- A user interface element that appears on top of the main content and requires user interaction before returning to the underlying page. In accessibility, modal dialogs must properly manage keyboard fo…
- Modality (Interaction Modality, Interface Modality)
- The sensory channel or communication method through which a user interacts with a computer system, such as visual (graphical displays), auditory (speech or non-speech audio), tactile (braille, haptic …
- Model Cards (Model card)
- Short structured documents, proposed by Mitchell et al. (2019), that accompany a machine learning model and report its intended uses, performance across relevant demographic subgroups, training data, …
- Model Human Processor (MHP, Human Processor Model)
- A cognitive architecture developed by Card, Moran, and Newell (1983) that models human information processing as three interconnected subsystems: perceptual, cognitive, and motor processors, each with…
- Model Reliability (AI Reliability, Model Trustworthiness)
- The degree to which an AI model consistently produces accurate, truthful, and complete outputs across different inputs and contexts. In the context of visual access technology for BLV users, model rel…
- Model-Based Sonification (MBS)
- A sonification approach in which a virtual model or simulation is constructed from the data, and sound is produced through the user's interaction with that model. Rather than passively mapping data to…
- Model-Based User Interface (MBUI, Model-Based UI)
- An approach to user interface design where the interface is generated or adapted automatically from abstract models that describe the tasks users need to perform, the data domain, the user's character…
- Model-View-Controller (MVC)
- A software architectural pattern that separates an application into three interconnected components: the Model (data and business logic), the View (presentation and user interface), and the Controller…
- Moderate-to-Vigorous Physical Activity (MVPA)
- A classification of exercise intensity used in public health guidelines that encompasses physical activity raising heart rate to 60-80% or more of heart rate reserve. MVPA is the threshold recommended…
- Modified Borg Scale (Borg CR10 Scale, MBS, Borg Scale)
- A self-report rating scale used to measure the perceived intensity of physical sensations such as breathlessness, exertion, or pain, ranging from 0 (nothing at all) to 10 (maximal). Originally develop…
- Modified Stave Notation (MSN)
