- Data Glove (digital glove, sensor glove, wired glove)
- A wearable input device equipped with sensors to capture hand and finger movements, positions, and orientations. Data gloves use technologies like gyroscopes, accelerometers, flex sensors, or fiber op…
- Hidden Markov Model (HMM)
- A statistical model used extensively in pattern recognition where the system being modeled is assumed to follow a Markov process with hidden (unobserved) states. HMMs have been foundational in both au…
- Isolated Sign Language Recognition (isolated SLR, word-level sign recognition)
- A sign language recognition task that focuses on identifying individual, pre-segmented signs rather than continuous signing sequences. In isolated SLR, each sign is captured as a separate video clip w…
- Multimodal Features (multimodal data, multimodal fusion)
- Information extracted from multiple sensory channels or data types—such as combining visual (RGB), depth, audio, and skeletal data—to improve recognition accuracy. In accessibility systems, multimodal…
- Sign Language Classifier (Classifier Sign, Depicting Sign, Classifier Predicate)
- A type of sign in sign languages that is not part of a fixed vocabulary but is created dynamically during discourse to represent a class of objects sharing a common shape, size, or physical characteri…
- Sign Phoneme (cheremes, sign language phoneme)
- The smallest contrastive units in sign language that bear meaning and distinguish one sign from another, analogous to phonemes in spoken language. Sign phonemes include hand shapes, movements, locatio…
- Signer-Independent Recognition (signer-independent SLR)
- A sign language recognition approach designed to work with signers whose data was not included in the training set. Similar to speaker-independent speech recognition, signer-independent systems must h…
- Skeleton Tracking (skeletal tracking, body tracking, pose estimation)
- Technology that detects and tracks the positions of human body joints (such as head, shoulders, elbows, hands) in real-time from camera or depth sensor data. In accessibility applications, skeleton tr…
