Acoustic Accessibility (Sound Accessibility)
An emerging framing of accessibility that considers a user's full acoustic environment - which sounds reach them, how loud, and in what mix - as a design surface to be adapted to individual sensory ne…
Active Noise Cancellation (ANC, Active Noise Control)
A technique that reduces unwanted ambient sound by using microphones to capture incoming noise and electronically generating an inverted (anti-phase) audio signal that destructively interferes with it…
Affective Congruency
The degree to which a system's sensory outputs, interactions, and feedback align emotionally with the user's current affective state and the emotional meaning the user attaches to the experience. Dist…
Cross-Modal Perception (Multisensory perception, Cross-modal integration)
The neural and perceptual integration of information arriving through two or more sensory channels — such as vision, hearing, touch, and proprioception — into a coherent experience of the world. Cross…
Cross-modal Congruency
The temporal, spatial, and semantic alignment of sensory cues during an interaction — for example, a visual event and its accompanying sound occurring at the same moment and in the same location, with…
Kinesthetic (Kinaesthetic)
Kinesthetic refers to the sense of body movement, limb position and muscular effort, arising from receptors in muscles, tendons and joints and closely related to proprioception. In accessibility and i…
Kinesthetic Perception (Kinesthesia, Proprioceptive Perception)
The sensory ability to perceive the position, movement, and forces acting on one's body and limbs through receptors in muscles, tendons, and joints. Kinesthetic perception encompasses awareness of lim…
Kinesthetics (Kinaesthetics, Kinesthesia, Kinesthetic sense)
The sense of body position, movement, and muscular effort derived from receptors in muscles, tendons, and joints. Kinesthetics is closely related to — and often used interchangeably with — propriocept…
Material Perception (Material recognition)
The perceptual processes by which people identify and characterize the materials that objects are made of — such as wood, metal, glass, leather, fabric, or stone — using visual, tactile, auditory, and…
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 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…
Olfactory Display (Olfactory Interface, Olfactory Feedback, Smell Display, Scent Display)
An olfactory display is a hardware system that delivers controlled scent stimuli to a user, typically as part of a virtual reality, augmented reality, or multisensory interaction system. Designs range…
Sensory Adaptation (Habituation, Olfactory Fatigue)
Sensory adaptation is the diminishing response of a sensory system to a constant or repeated stimulus over time. Classic examples include no longer noticing a steady smell, becoming accustomed to ambi…
Sensory Processing Sensitivity (SPS, Sensory Processing Differences)
Sensory Processing Sensitivity refers to differences in how an individual perceives, filters, and responds to sensory input across modalities such as vision, sound, touch, taste, and proprioception. I…
Somatosensory (Somatosensation, Bodily Sensation)
Relating to the sensory system that processes touch, pressure, temperature, pain, and body position (proprioception). The somatosensory system is crucial for accessibility technologies that bypass vis…
Synaesthesia (Synesthesia)
Synaesthesia is a perceptual phenomenon in which a stimulus in one sensory modality automatically and involuntarily triggers an additional experience in a different modality or sub-modality - for exam…
Tactile Stimulation (Tactile Feedback, Cutaneous Stimulation)
Tactile stimulation refers to the use of physical sensations delivered to the skin to convey information, typically through vibrations, pin arrays, textures, or pressure changes. In assistive technolo…
Texture Perception (Texture sense, Tactile texture perception)
The perceptual capacity to detect and characterize surface properties — roughness, smoothness, bumpiness, graininess, stickiness, and directional patterns — through touch, vision, or cross-modal integ…
