- Gestural Input (Gesture-based Input, Touch Gestures)
- Input methods that interpret finger movements on a touchscreen as commands, including taps, swipes, pinches, and multi-finger gestures. For blind users, gestural input must be performed without visual…
- Gestural Interaction (Gesture-Based Interaction)
- A mode of human-computer interaction in which users control systems through movements of the body — hands, arms, head, eyes, or whole body — captured by sensors such as accelerometers, cameras, IMUs, …
- Gestural Interface (Gesture-Based Interface, Gestural Controller)
- An input device or system that interprets body movements, hand gestures, or physical expressions as control signals for digital systems. In accessibility and music contexts, gestural interfaces are pa…
- Gesture Elicitation (User-Defined Gestures)
- Gesture elicitation is a participatory design method where end users are asked to invent gestures for a set of device functions, rather than having gestures predetermined by designers or engineers. Pa…
- Gesture Elicitation Study (Gesture Elicitation, User-Defined Gestures)
- A research methodology in which participants are presented with the effects or outcomes of actions (called referents) and asked to propose gestures they would naturally perform to trigger those effect…
- Gesture Input (Gestural Input, Gesture-Based Input)
- A form of human-computer interaction where users perform physical movements—such as swipes, taps, pinches, or mid-air hand motions—to issue commands or provide input to a digital device. Gesture input…
- Gesture Input (Gesture Recognition, Gesture-Based Interaction)
- An input method that uses physical movements of the body — typically hands, fingers, arms, or head — to interact with digital systems. Gesture input includes touchscreen gestures (swipes, taps, pinche…
- Gesture Interaction (Gesture-based interaction, Gestural interfaces)
- An input modality in which users control digital systems through hand, arm, or body movements detected by cameras, depth sensors, IMUs, or wearable devices rather than through traditional keyboards, p…
- Gesture Recognition (Gesture Detection)
- The computational process of identifying and interpreting human gestures—typically hand, arm, or body movements—using sensors and machine learning algorithms. Gesture recognition systems analyze data …
- Gesture Recognition Threshold (Activation Threshold, Gesture Detection Threshold)
- The predefined parameters that a gesture recognition system uses to determine whether a user's hand movement constitutes a valid gesture input. These thresholds specify requirements such as the exact …
- Gesture Set Design (Gesture Vocabulary Design)
- The process of selecting and defining a collection of gestures that users will perform to interact with a system, including decisions about which physical movements map to which functions. Effective g…
- Gesture Typing (Swipe Typing, Trace Typing, Glide Typing, Shape Writing)
- A text entry method on touchscreen devices where the user enters a word by continuously gliding their finger from letter to letter on a virtual keyboard without lifting it, rather than tapping each ke…
- Gesture sonification (Touch sonification, Gesture-to-sound mapping)
- The technique of converting touchscreen finger movements into real-time audio representations by mapping spatial position to sound parameters — typically pitch for vertical position and stereo panning…
- Gesture vocabulary (Gesture set, Interaction gesture repertoire)
- The complete set of touch gestures recognized and used by a device or application, including single-stroke gestures (swipes, flicks), multistroke gestures (multi-tap, draw-then-tap), and multitouch ge…
- Gesture-Based Input (Gesture input, Gestural input, Gesture-based text entry)
- An input method that interprets finger or hand movements — such as swipes, taps, and drawn paths — as commands or text characters. For people with visual impairments, gesture-based input on touchscree…
- Gesture-Based Interaction (Gesture Control, Gestural Input)
- A mode of human-computer interaction where users control digital systems through hand or body movements detected by cameras or sensors, rather than through traditional input devices. In mixed reality …
- Gesture-Based Interface (Gestural Interface, Gesture Recognition Interface)
- An interaction system that interprets human gestures—such as hand movements, body poses, or finger motions—as input commands. Gesture-based interfaces can use cameras, accelerometers, touch surfaces, …
- Gesture-based interaction (Gestural interface, Touchless interaction)
- An interaction modality where users control technology through body movements, hand gestures, or postures detected by sensors such as depth cameras, rather than through traditional input devices like …
- Ghost Cursor (Phantom Cursor, Proxy Cursor)
- A visual indicator displayed on screen that shows a potential cursor position, used in speech-based and alternative cursor movement systems. Multiple ghost cursors can be displayed simultaneously, typ…
- Gig Economy (Platform Economy, On-Demand Economy)
- An economic model characterized by short-term, flexible, and freelance work arrangements facilitated through digital platforms, rather than traditional permanent employment. For people with disabiliti…
