- Audio-First Design (Audio-Centric Design, Sound-First Design)
- A design approach that prioritizes audio as the primary interaction modality rather than treating it as a secondary alternative to visual interfaces. Audio-first design is particularly relevant for cr…
- Audio-Haptic Feedback Layering (Multimodal Feedback Layering)
- A design technique for managing multiple concurrent non-visual feedback signals by strategically prioritizing, staggering, and adjusting audio and haptic cues to prevent sensory overload. Techniques i…
- Audio-Language Model (ALM, Audio LLM)
- A multimodal artificial intelligence model that jointly processes audio signals and natural language text, enabling it to generate detailed textual descriptions of audio content, answer questions abou…
- Audio-Reactive Visuals (Sound-Reactive Displays, Audio-Visual Feedback)
- Visual display systems that respond in real time to audio input, translating sound properties such as frequency, amplitude, pitch, and rhythm into light, color, and movement. In accessibility contexts…
- Audio-Spatial Mapping (Auditory-Spatial Mapping, Sound Spatialization)
- A technique that uses sound properties such as pitch, volume, panning, and spatialization to represent spatial information non-visually. In accessibility contexts, audio-spatial mapping helps blind an…
- Audio-Tactile (Audio-Tactile Interaction, Audio-Haptic)
- An interaction paradigm that combines tactile (touch-based) and auditory feedback to convey information. Audio-tactile systems pair physical surfaces, such as raised maps or 3D-printed models, with lo…
- Audio-Tactile Interface (Audio-Haptic Interface, Multimodal Tactile Interface)
- A user interface that combines tactile (touch-based) interaction with auditory feedback to convey information that is otherwise visual. Audio-tactile interfaces are widely used in accessibility to mak…
- Audio-Video Synchrony (AV Sync, Lip Sync, Audio-Video Synchronization)
- The temporal alignment between audio and video streams in multimedia content or real-time communication. When audio and video are not properly synchronized, the mismatch can significantly impair speec…
- Audio-Visual Entrainment (AVE, Brainwave Entrainment)
- Audio-visual entrainment (AVE) is a therapeutic technique that uses rhythmic light and sound stimuli to influence brainwave activity, guiding the brain toward specific frequency states associated with…
- Audio-tactile interface (Audio-tactile system, Talking tactile)
- An interactive system that combines physical tactile surfaces with electronic audio feedback, providing spoken labels, descriptions, or sonified data when the user touches specific areas of a tactile …
- Audio-to-Haptics Translation (Audio-haptic translation, Audio-to-vibration conversion)
- A class of techniques that convert audio signals — either recordings of real-world interactions or AI-generated sounds — into vibrotactile patterns that can be rendered through actuators embedded in p…
- Audiobook (Audio Book, Talking Book)
- A recording of a book or other text being read aloud, providing an alternative to visual reading. Audiobooks are an important accessible format for people with visual impairments, dyslexia, or other p…
- Audiogram (Hearing Test Chart, Pure-tone Audiogram)
- An audiogram is a graph of a person's hearing thresholds measured across a range of frequencies — typically 250 Hz to 8 kHz — plotted separately for each ear. Thresholds are expressed in decibels hear…
- Audiophotography (Audiophotograph, Audio Photograph, Sound Photograph)
- A medium proposed by Frohlich and Tallyn in which a photograph is packaged together with an associated audio recording — typically ambient sound captured at the moment of the shutter, a spoken caption…
- Audism
- Systemic discrimination and prejudice against deaf and hard of hearing people, rooted in the belief that hearing and spoken language are inherently superior to deafness and sign language. Coined by To…
- Auditory Channel Conflict (Audio Channel Competition, Auditory Interference)
- A situation where multiple audio streams compete for a user's attention through the same sensory channel, reducing comprehension and increasing cognitive load. For blind and visually impaired users wh…
- Auditory Comprehension (Listening Comprehension)
- The cognitive and linguistic ability to understand spoken language in real time, including recognising words, parsing grammar, holding clauses in working memory, and integrating meaning across sentenc…
- Auditory Description (Audio Description, Spoken Description, Verbal Description)
- The practice of providing spoken narration that describes visual information, making content accessible to people who are blind, have low vision, or benefit from auditory reinforcement of visual conte…
- Auditory Display (Audio Display, Auditory Interface)
- The use of sound to convey information, data, or interface state to users. Auditory displays encompass a range of techniques including sonification, earcons, auditory icons, and speech output. In acce…
- Auditory Feedback (Audio Feedback, Auditory Display)
- The use of sound — including tones, sound effects, earcons, and speech — to convey information about system states, user actions, or environmental changes. In accessibility, auditory feedback serves a…
