- Haptic Interface (Haptic Device, Tactile Interface, Touch Interface)
- An interface that communicates with users through the sense of touch, using vibrations, forces, or textures to convey information. Haptic interfaces can range from simple vibration motors in mobile de…
- Haptic Magnetism (Force Attraction, Haptic Gravity)
- A technique used in haptic interfaces where virtual attractive forces pull a haptic device (such as a stylus) toward nearby virtual objects, simulating a magnetic or gravitational effect. In accessibl…
- Haptic Music Technology (Vibrotactile Music Systems, Haptic Music Interfaces)
- Technologies that convey musical information through touch, typically using vibrotactile feedback to transmit sound properties such as rhythm, frequency, and amplitude to the body. Haptic music techno…
- Haptic Perception (Tactile Perception, Touch Perception)
- The ability to perceive and interpret information through the sense of touch, including the detection of texture, shape, temperature, pressure, and vibration. Haptic perception is a primary informatio…
- Haptic Pointing Device (Force Feedback Mouse, Haptic Mouse, Force Feedback Pointing Device)
- An input device that combines the pointing functionality of a mouse or stylus with the ability to generate physical forces that the user can feel through their hand. Unlike a standard mouse that provi…
- Haptic Rendering (Haptic display rendering)
- The process of computing and outputting touch-based signals — forces, vibrations, textures, or friction — so that a user can perceive virtual or remote objects through the sense of touch. Haptic rende…
- Haptic Technology (Haptics, Touch Technology)
- Technology that creates tactile experiences through the application of forces, vibrations, or motions to the user, enabling interaction through the sense of touch. Haptic technologies range from simpl…
- Haptic Toolkit (Tactile Prototyping Toolkit)
- A collection of physical materials designed to enable hands-on design and prototyping through touch rather than vision. In accessible design research, haptic toolkits are developed specifically for bl…
- Haptic User Interface (Haptic UI, Haptic Interface)
- A user interface that communicates information through the sense of touch, enabling users to interact with virtual or digital objects by feeling their physical properties such as shape, texture, weigh…
- Haptic Virtual Reality (Haptic VR, Feelable Virtual Environment)
- Haptic virtual reality refers to virtual environments that incorporate touch-based feedback, allowing users to feel virtual textures, shapes, and objects through force-feedback devices. Unlike visual-…
- Haptic Wearable (Haptic Wearable Device, Wearable Haptic Technology)
- A body-worn electronic device that communicates information through touch sensations such as vibration, pressure, or temperature changes. In accessibility contexts, haptic wearables can serve as assis…
- Haptics (Haptic Technology, Haptic Feedback)
- Technology that creates tactile sensations through vibrations, forces, or motions to simulate touch and physical interaction with digital content. In accessibility, haptics enables people who are blin…
- Hard of Hearing (HoH, HH)
- A term describing people with hearing loss ranging from mild to severe who typically have some functional hearing, often with the assistance of hearing aids or other amplification devices. Unlike many…
- Harm OCD (Harm Obsessions)
- A subtype of OCD characterized by intrusive, unwanted thoughts about causing harm to oneself or others, despite having no desire or intention to act on these thoughts. People with harm OCD may experie…
- Harm Reduction
- An approach that prioritizes minimizing negative consequences of potentially risky behaviors rather than demanding complete abstinence or compliance with prescribed rules. In accessibility and disabil…
- Hate Speech
- Hate speech refers to expression that attacks, demeans, or calls for violence or discrimination against individuals or groups based on protected characteristics such as race, ethnicity, religion, nati…
- Head Control (Head-Controlled Interface, Head Mouse, Head Pointer)
- An alternative computer input device that translates head movements into cursor movements on screen, enabling people who cannot use their hands or arms to operate a computer. Head control systems typi…
- Head Pointer (Head Mouse, Head Tracking Device)
- An assistive technology input device that translates head movements into cursor movements on screen, allowing people who cannot use their hands or arms to control a computer. Head pointers can be phys…
- Head Pointing (Head-Controlled Pointing, Head Mouse)
- Head pointing is an alternative input method that maps head movements to cursor position on a computer screen, enabling hands-free mouse control. The user moves their head to direct the cursor, with t…
- Head Pose Estimation (Head Orientation Detection, Gaze Direction Estimation)
- A computer vision technique that determines the orientation or direction a person's head is facing, typically classifying whether someone is looking towards or away from the camera. In accessibility c…
