- Capacitive Touchscreen (Capacitive Touch Display, Cap Touch)
- A capacitive touchscreen is a type of display that detects touch input by sensing changes in the electrical field caused by the conductivity of a human finger or conductive stylus. Unlike resistive to…
- Click-on-Lift (Lift-off Activation, Release Activation)
- An interaction technique where a touch target is activated only when the user lifts their finger from the screen while still within the target area, rather than registering the action at the point of …
- 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…
- Risk-Free Exploration (Safe Exploration)

- Surface Haptics (Surface Haptic Technology)
- A branch of haptic technology that creates tactile sensations directly on a flat surface, such as a touchscreen, by modulating the friction between a fingertip and the display. Unlike conventional vib…
- Touch Target (Tap Target, Hit Area, Target Size)
- A touch target is the area on a touchscreen interface that responds to a user's tap or touch input. Accessibility guidelines recommend minimum touch target sizes to ensure that people with motor impai…
- Touchscreen Accessibility (Touch Interface Accessibility)
- Touchscreen accessibility refers to the design principles, techniques, and assistive technologies that make touchscreen devices usable by people with disabilities. This includes screen reader gestures…
- Variable Friction (Variable Friction Display, Friction Modulation)
- A surface haptics technique that dynamically adjusts the friction between a user's fingertip and a touchscreen surface to create the sensation of different textures. Typically achieved through ultraso…
