- Multiple Disabilities (Co-occurring Disabilities, Comorbid Disabilities)
- The presence of two or more disabilities in a single individual, which may include combinations of physical, sensory, cognitive, mental health, and chronic health conditions. People with multiple disa…
- Multiple Disabilities (Multi-impairment, Multiple Impairments, Combined Disabilities, Complex Disabilities)
- The presence of two or more disabilities in the same individual, such as combined motor and visual impairments, or deafblindness. People with multiple disabilities often face compounded accessibility …
- Multiple Impairments (Multiple Disabilities, Complex Disabilities, Co-occurring Impairments)
- The presence of two or more concurrent impairments — such as sensory, cognitive, physical, or neurological — in a single individual that together create complex accessibility needs not adequately addr…
- Multiple Resource Theory (Wickens Multiple Resource Model)
- A cognitive psychology theory proposed by Christopher Wickens that explains how humans allocate attention across concurrent tasks. The theory posits that humans have separate pools of cognitive resour…
- Multiple sclerosis (MS)
- A progressive disease of the central nervous system caused by the immune system attacking the protective myelin sheath around nerve fibres, causing them to fail or misfire. The randomness of the damag…
- Multiply Marginalized (Multiply Marginalised, Multiply Marginalized Disabled People)
- A term used in disability justice and intersectional scholarship to describe people whose lived experience sits at the intersection of multiple marginalised identities — for example, disabled people w…
- Multisensory (Multisensory Design, Multisensory Interaction)
- An approach to design and interaction that engages multiple human senses — such as sight, hearing, touch, smell, and taste — to convey information and create richer experiences. In accessibility, mult…
- Multisensory Experience (Multi-Sensory Experience, Multisensory Design)
- An experience designed to engage multiple senses simultaneously, including touch, hearing, smell, taste, and proprioception, rather than relying primarily on vision. In accessibility contexts, multise…
- Multisensory Integration
- The neural and perceptual process by which the brain combines information from different sensory modalities — sight, hearing, touch, proprioception — into a unified percept. Integration relies on temp…
- Multisensory Interaction (Multisensory HCI)
- Multisensory interaction is an HCI research area concerned with designing and studying systems that engage two or more human senses - sight, hearing, touch, smell, taste, proprioception - simultaneous…
- Multisensory Interface (Multimodal Interface, Multi-Sensory Feedback)
- An interface that communicates information through multiple sensory channels simultaneously, such as visual, auditory, and tactile (haptic) feedback. Multisensory interfaces are particularly valuable …
- Multisensory Stimulation (MSS)
- A therapeutic and design approach that intentionally coordinates multiple sensory modalities — visual, auditory, tactile, olfactory, and kinetic — to support affective well-being, cognitive engagement…
- Multitouch Surface (Multi-Touch Interface, Multitouch Interface, MTS)
- A multitouch surface is an input device that uses optical or capacitive sensors to detect and track multiple simultaneous finger contacts on a flat surface. Unlike conventional touchpads that rely on …
- Multivariate Data (Multivariate Dataset, High-Dimensional Data)
- Data in which each observation or sample has more than two measured variables (dimensions). Analysing multivariate data is a core task in statistics, science, and business intelligence, but presenting…
- Muscle Atrophy (Muscular Atrophy)
- A condition involving the wasting or loss of muscle tissue, resulting in decreased muscle strength and endurance. Muscle atrophy can occur due to disuse, neurological conditions, or disease, and often…
- Muscle Contraction (Voluntary Muscle Activation)
- The deliberate tensing of a muscle group that generates an electrical signal (electromyographic or EMG signal) detectable by surface electrodes. In assistive technology, intentional muscle contraction…
- Muscle Fatigue (Motor fatigue)
- A decline in the capacity of a muscle or muscle group to generate force or sustain activity after prolonged or repeated exertion. In human-computer interaction, muscle fatigue is a central concern for…
- Muscle-Computer Interface (MCI (Muscle-Computer Interface), EMG Interface)
- An input modality in which signals generated by muscle contractions — typically recorded via surface electromyography (sEMG) sensors worn on the forearm or other muscle group — are interpreted by a co…
- Muscular Dystrophy (MD)
- A group of inherited genetic conditions that cause progressive weakness and loss of muscle mass, affecting mobility, upper limb function, and in some forms, respiratory and cardiac function. People wi…
- Muscular Dystrophy (MD)
- A group of inherited genetic conditions that cause progressive weakness and degeneration of skeletal muscles, the muscles that control movement. There are many types of muscular dystrophy varying in s…
